RE: [lazarus] ColorToRGB in console app
Hi Graeme, Thanks for the tips. Console apps with the Laz GUI linked in (i.e., linked against a widgetset via inclusion of interfaces unit) work fine on Windows and Carbon and even with GTK on OS X if run in an X termimal. However, I would like to be able to have a truer console app (and a much smaller one too). ColorToRGB is widgetset-dependent so I can't use that if I want a true console app. Another problem I've run into is trying to decide what RGB value to use for color constants. For example, ColorToRGB(clBtnFace) returns different RGB values on Windows, OS X Carbon and OS X GTK, as implemented by the widgetsets' GetSysColor. Probably different values would also be returned on the same platform depending on user preferences too. So I guess my problem is how to map color constants for use, say, in other programs or in a Web browser. Maybe just use a default Windows set of RGB values or something would make sense. Thanks. -Phil -Original Message- From: Graeme Geldenhuys [mailto:[EMAIL PROTECTED] Sent: Monday, February 11, 2008 2:09 AM To: lazarus@miraclec.com Subject: Re: [lazarus] ColorToRGB in console app On 10/02/2008, Hess, Philip J [EMAIL PROTECTED] wrote: Of course, now the app has the same issues as any Mac GUI app compiled with GTK, in that even though it's a console app (sort of), it will only run under X11.

You can't include the 'interfaces' unit in a console application because it requires (pulls in) GUI code. You will not notice anything under Windows, because Windows always has a GUI installed. Under Linux it's easily noticed when you don't run a X Server and try an execute a console application that uses 'interfaces' unit. I had this same issue in the tiOPF project and console unit tests on my Linux server which doesn't run a X Window server installed. Some unit tests required the clipboard, which is a GUI feature in LCL or VCL. I had to rework the unit tests to exclude those tests when run as a true console application. RGB value _or_ a color constant like clBtnFace (value of 15). If someone passes a color constant to one of these functions, they'll get an unexpected result. So it seems as though RedGreenBlue, etc. should either call ColorToRGB first or else the param type should be Again correct and what I forgot to mention in my previous post. If you pass in a cl color alias (like clBtnFace etc) you first need to lookup the RGB equivalent color value via ColorToRGB. In fpGUI it's possible to do without requiring a true GUI installed, but I'm not sure what would happen under Windows etc...

[lazarus] ColorToRGB in console app
I need to call ColorToRGB in a console app. Adding Graphics to uses allows lazbuild to compile the console app okay, but I get an AV when running it, presumably because the widgetset that actually implements ColorToRGB isn't getting linked into the app, as evidenced by otool -L (on Mac): /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 88.1.10) If any widgetset code were linked in, I would see something like this: /System/Library/Frameworks/Carbon.framework/Versions/A/Carbon (compatibility version 2.0.0, current version 128.0.0) /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 88.1.10) This console app runs okay on Delphi. Is there something I'm missing here or is this just not possible with Lazarus? Thanks. -Phil
RE: [lazarus] ColorToRGB in console app
Excellent, that's what I was forgetting. Of course, now the app has the same issues as any Mac GUI app compiled with GTK, in that even though it's a console app (sort of), it will only run under X11. And no way to compile for Carbon with lazbuild unless the framework carbon stuff already set in the .lpi. Also, looking at some of the functions in Graphics.pp, I wonder if it's confusing to use TColor for params with functions like RedGreenBlue, InvertColor, etc. TColor can be a full RGB value _or_ a color constant like clBtnFace (value of 15). If someone passes a color constant to one of these functions, they'll get an unexpected result. So it seems as though RedGreenBlue, etc. should either call ColorToRGB first or else the param type should be LongInt or something to make it clearer that a color constant should not be passed. Same with ColorToRGB - in Delphi the return type is LongInt, not TColor, since it only returns RGB values, not color constants.

RE: [lazarus] make, MacOSX
Hi Albert, The Lazarus installer creates the lazarus.app bundle and puts the structure inside it that OS X wants. For apps you develop yourself you can use the create_app_mac.sh script to create the app's .app bundle. Open the script in a text editor to see what it's doing. Note that for convenience both lazarus.app and the bundle created by create_app_mac.sh use a symlink to the actual executable in the same folder as the .app. For distribution you would want to replace the symlink in the bundle with the actual executable file.

After running my report on my older version of Linux I have indeed seen

Lazarus problem. I know its not CUPS or the print filters because my
other programs don't have any trouble printing Landscape.
So any insight as to what other libraries Lazarus (on Linux) is using
for printing would be a big help to try and determine where the failing
component is. Maybe its a GTK thing? I use the TPrintDialog component to
setup the initial print environment and then in code I force it to

that when you configure a print job for landscape it doesn't take
affect
until the second page. The first page still prints portrait. Here
is a
snippet of code to demonstrate:
if not PrintDialog1.execute then exit;
with printer do begin
orientation:=poLandscape;
PaperSize.PaperName:='Letter'; { This should be the default }
BeginDoc;
canvas.TextOut(100, 100, 'Portrait Text')
newpage;
canvas.TextOut(100, 100, 'Landscape Text')
EndDoc;
end;
I've even tried setting the landscape setting in the print dialog
caused by the first line and I get exactly the same results. Is
there a
fix for this?

Gnome shares the default browser from gconf, kde you can use kfmclient which will revert back to the configured one, every other desktop doesn't do anything like that at all. Pretty much every file manager not part of either gnome or KDE uses brute force or 'you have to configure it' approach.

I have no idea why it didn't take off, but it didn't - sad because it would have been an ideal solution. Perhaps the code should be expanded to check for the existence of $BROWSER first, and THEN start brute-forcing command names ? Other than that, it really cannot be much better than it is. Sorry.

Actually I'm looking at a slightly wider problem which is how to know what program to invoke in order to open any file: using Win-32 ShellExecuteEx() I can pass a file name with either a known suffix (.txt) or a known scheme (http:) and a suitable program is started, similarly with KDE and presumably also with Gnome. The test app that I'm recoding to get into Lazarus has a couple of right-button options: one of them treats highlighted text as a file name and opens it using another instance of the same program, the other treats it as a command and executes it. Under Win-32 the command can have a .txt suffix which opens whatever editor is associated, an http: scheme which opens the default browser and so on, it would be nice to be able to duplicate this functionality even if it was limited to desktops which conform to freedesktop.org. -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
RE: [lazarus] Helpfiles for Lazarus apps
I think the issue is that most programs, whether word processors or browsers, if they receive a file spec that includes a page anchor (e.g., #something with HTML) the program sees this as part of the file name and chokes. It's been a while but I think I concluded that a separate HTML file would be needed for each topic with the Lazarus help system on Linux and OS X if a browser is used to view the help. My original investigation was for OS X. The Carbon API's AHGotoPage function does allow an anchor to be specified for scrolling to with the Mac Help Viewer, but this would require direct calls to Carbon from my app rather than through the Lazarus interface. I never got around to following up on this.

RE: [lazarus] Building Lazarus (first time ever) on Mac OS X 10.5 (Leopard) fails - fink's apt-get sources has no glib or other packages.
Hi Warren, The Lazarus snapshots for OS X include an app bundle (lazarus.app) but the Lazarus executable is still compiled for and dependent on GTK so you can't launch from it the bundle until you've recompiled the IDE for the Carbon widgetset. See this link for more information, including an uninstall script that gives the location of all FPC and Lazarus files installed by the snapshot installers: http://wiki.lazarus.freepascal.org/OS_X_Programming_Tips The Lazarus folder is read-only. To get to it with Finder, choose Go | Go to Folder and enter /usr, then navigate to /usr/local/share. Damien's script should work to recompile the IDE because it changes the ownership of the Lazarus folder to make it writeable. You can also do what I do which is simply to use Finder to copy the Lazarus folder into my user area and recompile it there. I would hope that within a couple months or so we'll have a stable, functional Carbon-based IDE and we can just forget all the GTK, X11 stuff for OS X and have a normal app bundle that's ready to go out of the box.

RE: [lazarus] Adding AllowFractionalPositioning to TCarbonDeviceContext
Tobias, I suspect that my e-mail was blocked because of the screenshots I attached. I won't try to resend them with this e-mail for fear of losing another posting. I'll post them shortly in separate e-mails. Are there any other controls affected besides TLabel? Most controls are Carbon native based, which do their own rendering. If BeginTextRender could determine what kind of LCL control it's being used for, perhaps it could automatically change the rendering on the fly. For example, if it's a TCustomControl or TGraphicControl it would use the integer-based spacing; if it's a TLabel it would use the fractional spacing. I'm just thinking out loud here before we commit to your proposed approach. I spent quite a bit of time testing this over the weekend. The flag that is causing the effect you see with TLabel is kATSLineUseDeviceMetrics. However, for my purpose I need both kATSLineUseDeviceMetrics and kATSLineDisableAllLayoutOperations. The latter is actually 5 flags in one so I haven't determined which of these I actually need, but the presence of this flag doesn't seem to affect TLabel any, only kATSLineUseDeviceMetrics does as far as I can determine. If you haven't had a chance to look at the link that Colin posted, please do so. Some very interesting stuff here: http://antigrain.com/research/font_rasterization/index.html I don't believe what we're seeing has anything to do with anti-aliasing. It appears as though the Carbon widgetset is leaving antialiasing alone, meaning it's set via system preferences. I played around with this (see text smoothing in Appearances in System Preferences) and it doesn't seem to have any effect on TLabel spacing. It's also possible to see these rendering issues in commercial software. I have a small .rtf file that shows some rendering problems when opened with OS X's TextEdit, but not with Word or Pages or any other word processor. Because each version of an OS probably has different or refined rendering smarts there will probably be rendering differences with the same software on different OS versions, so you might find it difficult to hit the TButton rendering target, since the way that it's actually rendered is unknown to us and may change from one version of OS X to the next.

Tobias, Please load the attached .rtf file into OS X's TextEdit. On my Mac, the t and o in to are jammed together in the first line but not in the second line.

RE: [lazarus] Adding AllowFractionalPositioning to TCarbonDeviceContext
Tobias, Here are 2 screenshots from my Mac. I don't see quite the same spacing issues that see. As you can see, in the prepatch screenshot, the TLabel text is wider than the TButton text. The screenshot with the patch shows that the TLabel's text has now been rendered with some of the inter-character spacing removed. See be and some and how the renderer has removed the extra pixel between b and e and between o and m. Probably what's happening here is the renderer, using font hints and other smarts, figures out that even though the typographic width of b with this font on my screen is somewhere between two whole numbers, removing the extra pixel required to display the fractional part of the character actually improves the display of the word. Also, to my eyes it looks like the renderer is using a slightly larger font with the TLabel, whereas in Tobias' original screenshot it appears as though it's using a slightly smaller font. That's probably a difference between our systems that we're seeing. I'm running OS X 10.4.10 on PowerPC. Display at 1056 x 792. I think this demonstrates the potential problems of trying to get simulated, non-native controls (TLabel) to look the same as native widget-based controls (TButton). If Apple were to change the way the button, edit, etc. are rendered in the future, then the TLabel would be off again. From Mattias' account, it sounds as though there might be some rendering surprises awaiting us in Leopard.

RE: [lazarus] Adding AllowFractionalPositioning to TCarbonDeviceContext
I agree with Giuliano, so add me to the ranks of the horrified. TFont.Pitch doesn't appear to be used in any LCL or Carbon widgetset logic, so that might work. Please be sure to document in the patch that this is used only as a switch and has nothing to do with mono vs proportional spaced fonts. Giuliano: I assume that you mean I would need to set my control's canvas Font.Pitch any time the font changes. That might be a lot of work (120,000 lines of code that I did not write) and having a single switch for the canvas would be better but I don't see any unused properties in TCanvas. I thought perhaps the TCanvas.TextFlags could be extended, but the LCL doesn't have TextFlags the way VCL does. Tobias: 2 of my e-mails were never posted to this list yesterday. Did you see the one where I attached screenshots showing different results than what you were getting? It appears there is some variation between systems on how text is rendered. Even with your patch the TLabel text does not look identical to the TButton text and the unpatched TLabel text doesn't look as bad as yours did.

RE: [lazarus] Carbon Widgetset: character spacing problems
SynEdit is not the only custom control that was fixed by the change to BeginTextRender that disabled the fractional positioning of characters. This was an important fix since proportional font characters do not have whole number widths, yet they can only be displayed on a device using whole pixels. Without disabling this, then width(char) x number of chars in string width(string), which is what was causing the problem in SynEdit (and any other text editor type custom controls). Note that all char and string width functions return a whole number, so individual char widths get rounded. Tobias, what fonts are you using? Could you post your example app. I'm not seeing the char positioning differences here. Please be careful making any changes to this.

RE: [lazarus] Carbon Widgetset: character spacing problems
Hi Mattias, I don't believe the issue is one of proportional fonts using monospaced font character spacing. Monospaced fonts use the same width for all chars. Disabling fractional positioning of the char glyphs means treating each char's width as a whole number. For example, if the period (.) has a width of 3.3, I believe this means treat it as having a width of 4.

RE: [lazarus] Carbon Widgetset: character spacing problems
Hi Mattias, Not sure if I follow your reasoning. In Windows, the ExtTextOut Dx param means use these character widths (in array pointed to by Dx) instead of the default character widths. Since Dx is otherwise ignored in the Carbon widgetset you're just using the Dx param as a switch. If Dx is nil, it means use fractional char widths; if non-nil it means don't use fractional char widths. Neither of these is consistent with how Dx is supposed to function. Who's to say what normal character spacing should be? Tobias might suggest that it should be as close as possible to the way OS X currently renders buttons. I might suggest that it should be as close as possible to the way Windows renders text (as in Write once compile anywhere). There's probably quite a lot going on here. Tomas is actually passing a total of 8 options, including options to turn off kerning, to use rounded text metrics instead of fractional, and others, as well as disabling fractional spacing in the rendering of the line.

RE: [lazarus] DOM bug with 64 bit installation
Michael, Thanks for pointing that out about ReadXMLFile. I see that my code has the same memory leak. I think the confusion lies in that with Delphi once TXMLDocument has been used to create the object, the file is loaded by setting the object's FileName property, so it would appear logical to do the equivalent with FPC: call ReadXMLFile and pass the TXMLDocument object. But looking at the XmlRead.pp source I see that ReadXMLFile's TXMLDocument parameter is out. Another point of confusion is that the corresponding WriteXMLFile function takes an already-instantiated TXMLDocument, whereas ReadXMLFile does not. Question: Is there any place where someone could know this without inspecting the XmlRead.pp source and understanding the implications of that out param?

Are you trying to use the osprinters unit? Don't do that. Use the Printers

the non-implemented Carbon printer files.
You'll also probably have to put something like this in Other Unit Files path:

Hi all,
this is possibly a silly error on my part. I have just updated to the
latest snapshot version of Lazarus/FPC. When I try and compile my Mac OS
X project the unit carbonprinters_h.inc is opened and the TCarbonPrinter
class is highlighted and the console window error message is :
carbonprinters_h.inc(7,3 Fatal : Syntax Error, 'IMPLEMENTATION'
expected but identifier TCarbonPrinter found
this include file is definitely missing an implementation section.
Btw, what does {%MainUnit ../osprinters.pp} imply? When I looked in that
directory all I found was osprinters.pas not osprinters.pp.
FPC compiler is listed as 2.2.1 and the Lazarus editor is listed as
v0.9.23 beta.

Tom is right. Almost everything is implemented and working with the Carbon widgetset. Even printing works. For now, you can use the Unix CUPS-based printer dialogs and TPrinter implementation. The dialogs aren't native like the Open, Save, etc. dialogs, but they do work fine now. The TPrinter implementation does use the Carbon API and is limited to the 4 font families built into the Postscript interpreter (Courier, Times, Helvetica, Symbol, which are very similar to the TrueType Courier New, Times New Roman, Arial, Symbol) but it does print correctly. One thing that's needed now is testing of the integration of Carbon with large, existing apps. For example, the Laz IDE is a good test of integration. The Laz IDE can be compiled with the Carbon widgetset and it actually works pretty well. There are a few big issues still and a lot of little cosmetic ones with IDE dialog sizes (too small to fit some of the controls with Carbon), but you can try it out and see the future. I'm thinking of creating a wiki page devoted to getting the Laz IDE working fully with Carbon. Would anyone be interested in that?

RE: [lazarus] Philip Hess' Carbon IDE WIKI idea
Jim, All Mac GUI apps should have an .app bundle. Here's how I created one for the Carbon-based Laz IDE: 1. First made copy of GTK-based Lazarus in case Carbon-based IDE doesn't work. Can use Finder or command line: cp -p lazarus lazarus-gtk 2. Started GTK-based Lazarus, then in Configure Build Lazarus: - Set everything to None, except Laz IDE. - Set LCL interface to carbon. - Unchecked Restart box since we don't want to start unbundled executable. - Entered this in Options: -k'-framework' -k'carbon' - Clicked Build button. 3. Exited GTK-based Lazarus. 4. Created .icns file. I just posted lazarus.icns to BugTracker, but you can also create this yourself with Icon Composer from mainicon.ico (in images folder). 5. Created app bundle with script: ./create_app_mac.sh lazarus Lazarus This will create Lazarus.app (with proper uppercase first char) and if it finds lazarus.icns will copy icon file into bundle. If the bundle has an icon file you'll see this on the dock when it's run. Script is available from: http://web.fastermac.net/~MacPgmr/Lazarus/ 6. Double-click Lazarus in Finder to start Carbon-based IDE. You can also drag and drop it onto Dock to start it from there.

Adriaan van Os helped us get a middle-sized PC Lazarus app moved into an xcode project. The carbon components this project uses, are working great. The low-level message loop is behaving nicely, doing what one would expect it to do responding to keyboard, mouse, updating controls, all that good stuff. The stuff our program exercises, include Main Menu (with check-items, and numerous hierarchical menus), Right-click menus, TForm, ShowModal, multiple TPanels in a TForm, TButton, TSpeedButton, Multiple TPaintBox in a TPanel, TScrollBar, TBevel, TLabel with default Black Text, TLabel with Colored Text/Background, TComboBox, TProgressBar, TMemo, TEdit, TProgressBar, TOpenDialog, TTimer. Dunno if every feature of each mentioned control is perfect (since I haven't tested every available feature of each control), but they are working exactly as they should in our use of each control. We still need to do some work on it, but here are some screenshots: http://www.errnum.com/html/MacACWScreenShots.html Have done Mac programming a long time, off'n'on, but am very ignorant of a lot of modern Mac details, especially the unix and command-line tools. Maybe I'm doing something wrong, but when I double-click startlazarus, it runs the IDE from the Terminal. A lot of things seem to work, but no top menu (except the Terminal top menu), and the message loop doesn't seem to be fully running. For instance, clicking on a lot of the buttons will open an appropriate window, but once the window is open, it doesn't do much and can't be dismissed. Am not complaining. Far from it. Am only describing it, in case the current IDE version is supposed to be doing more and I haven't done something necessary to get it running better. Do the developers generally run 'all command line all the time', or do they work on the IDE project in an XCode project? Does the IDE ultimately need to be built into a bundle to become double-clickable with a menu and fully functional message loop and such? The carbon application.run loop is already so well-behaved on our middle-sized program, that it seems that the code ought to be pretty close to 'prime time' to run the IDE pretty fully (albeit with perhaps some initially missing features and bugs to clean up)? Its looking great. Congrats to all the folks who programmed this. jcjr On Oct 14, 2007, at 12:48 PM, Hess, Philip J wrote: Tom is right.

RE: [lazarus] Lazarus and Gtk2 under Mac OS X
Felipe, Instead of adding the wiki lines to your fpc.cfg, just specify them in an additional .cfg file on the Compiler Options Other tab for use when compiling with gtk2. If these lines interfere with gtk, then just uncheck the Use additional Compiler Config File box. I've attached my original gimplib.cfg file to this message. Also, to run an executable that's linked against the Gimp libraries, you have to export some of the Gimp gtk2 library locations. The easiest way to do this is with the attached script file. Run Lazarus like this: ./glaunch.sh lazarus That's the way Gimp is launched and I adapted my script from Gimp's. Study the script for more information.

I can't think of any reason why 2.0.4 would still need to be used for the snapshots. A disadvantage to having users work with 2.0.4 is that they'll be posting bugs that might already have been fixed.

RE: [lazarus] Roadmap Status of features
The setting made with SetTextAlign is used by TextOut and ExtTextOut. Perhaps SetTextAlign was in winapi.inc because this sort of compatibility was planned at one point. Delphi code that calls SetTextAlign to set the text alignment flags won't work correctly when it then calls TextOut or ExtTextOut since SetTextAlign is not implemented.

RE: [lazarus] Roadmap Status of features
(1) General status of widgetset's Win API support. There are lots of TODO's and implement this in gtkwinapi.inc and even win32winapi.inc doesn't appear to be complete. Win API support is one gauge of how well many 3rd-party Delphi components would be supported on Lazarus. What do you mean with win32winapi.inc doesn't appear to be complete? Maybe TODO means something different to you than it does to me. There are a lot of TODO's in win32winapi.inc, which tells me that it's not complete. Also, these functions are defined in the LCL winapi.inc, but not implemented even in win32: GetMapMode SetMapMode SetTextAlign There are probably others. All functions defined in winapi.inc should be implemented in all widgetsets, even if just stubs. And if stubs, they should at least use DebugLn or even raise an exception so programmers are notified that they're not implemented. Thanks. -Phil winmail.dat

[lazarus] Roadmap Status of features
Felipe, Good idea adding the Status of features table to the Roadmap page: http://wiki.lazarus.freepascal.org/Roadmap#Status_of_features_on_each_wi dgetset I wonder if it would be useful to list a few other things here too: (1) General status of widgetset's Win API support. There are lots of TODO's and implement this in gtkwinapi.inc and even win32winapi.inc doesn't appear to be complete. Win API support is one gauge of how well many 3rd-party Delphi components would be supported on Lazarus. (2) Status of non-visual components (a) TMetafile and TMetafileCanvas - still missing although I understand there's an implementation for win32 that's not part of LCL. (b) TClipboard - still missing GetAsHandle method. In Delphi this is typically used to get the handle to clipboard contents in a specified format, which is then passed to GlobalLock to get a pointer to the contents' first byte. Also probably need SetAsHandle. Both of these are declared but commented out in LCL's TClipboard. Doesn't appear to be anything equivalent to these in LCL's TClipboard that could be used instead. Since the combination of GetAsHandle and Win API GlobalLock is used simply to get at the clipboard contents, perhaps a GetAsPtr method could be added if there's a widgetset-independent way of getting a pointer to the clipboard memory. (c) TPrinter - missing GetPrinter method. In Delphi this is typically used to get printer device capabilities. Doesn't appear to be anything equivalent to this in LCL's TPrinter. Thanks. -Phil

RE: [lazarus] LCL in DLL
This has never worked. There was a time when you could put a form in a DLL and it would start okay (on Windows), but it wouldn't respond to keyboard inputs, as I recall. Now I can't even get a DLL containing a form to start without crashing the host app. On Delphi this works fine and you just set the DLL form's Application.Handle to the calling app's Handle to integrate it with the main app. I tested this with OS X recently too: same crash.

RE: [lazarus] Carbon may become deprecated soon
Run otool -L on various OS X executables and libraries (.dylib). You'll see that a lot of programs use the Carbon framework, either exclusively or in tandem with the Cocoa framework. All of these programs would be affected by a move away from Carbon. This includes things like the Qt libraries. However, deprecated does not mean eliminated. Apple has been pushing Cocoa since 10.0, but met fierce resistance from developers who didn't want to rewrite everything. Eventually Cocoa will probably be desirable from the point of view of new things added to it that aren't available via the traditional Carbon API. At that point it might be reasonable to develop a Cocoa-based widgetset. In the meantime I'm just grateful that we have a native widgetset for Lazarus in Carbon. Once the IDE is Carbon-based I imagine there will be an increase in the number of Mac programmers taking another look at Lazarus who were scared off by GTK, X11, fink, etc. Thanks. -Phil -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Tuesday, June 19, 2007 4:12 PM To: lazarus@miraclec.com Subject: [lazarus] Carbon may become deprecated soon Hi, The most important point of the day was : no 64 bits for Carbon.

[lazarus] Open-doc event handler for OS X Carbon
On Windows, if your app is associated with a specific file extension, if a user double-clicks a file of that type Windows starts another instance of your app, which can then determine the file that launched it by inspecting ParamStr(1). On OS X, if your app is associated with a specific file (via creator code or extension), if a user double-clicks this file OS X checks to see if your app is running - if not, it starts it - then sends an open-doc Apple Event to your app with information about the file that was double-clicked. Double-clicking can occur at anytime your app is running or another app could send an open-doc event to your app to have it open a file. The timing of these events means that putting this information in ParamStr(1) doesn't make sense the way it does with an OS X console app. Instead, this open-doc event needs to be handled by an event handler that your app installs. I've attached code with an example handler. OS X programmers can test this by calling InitOpenDocHandler in your main form's FormCreate method, passing a pointer to a method of the form that has the required parameter signature. When a file associated with your app is double-clicked, this event handler will call your form's method, passing the file's path. To associate a file with your app, select the file and press Cmd+I, then choose your app in the Info dialog that pops up. The question is where this event handler code should go. If it's put in the Carbon widgetset, then programs would need to add its unit to their uses. Normally we don't specify widgetset units in our apps, only the LCL units. There probably isn't anything that corresponds to this in the LCL, so it would be unique to the Carbon widgetset. Any ideas or suggestions? Thanks. -Phil CarbonOpenDoc.pas Description: CarbonOpenDoc.pas

RE: [lazarus] Report Tools for Lazarus
It's not a report tool, per se, but you can use FPC's RtfPars unit to create an RTF document, then display it in the user's word processor. Two units that simpify this are included in the XDev Toolkit: http://wiki.lazarus.freepascal.org/XDev_Toolkit The advantage to generating the report as RTF is that you have excellent control over the final look of the report since you can use any RTF formatting. Plus it's already in a form that the user can then browser, edit, print or save, without any export step required.

RE: [lazarus] OutKafe 5.1.0 Released !
Hi A.J., What version of Postgres are you using? I see that there are several binary downloads available from the Postgres site. Any interest in a Mac client? I note that Postgres doesn't have binary download for Mac. Fink does, but it looks out of date and nothing is listed for the current version of OS X. I'm usually a little reluctant to get involved with software that doesn't support all 3 major platforms. For many Mac users putting something on fink is kind of like putting up a sign that says We don't really expect anybody to use this. http://pdb.finkproject.org/pdb/package.php/postgresql Thanks. -Phil -Original Message- From: A.J.

RE: [lazarus] OutKafe 5.1.0 Released !
Hi A.J.,
Googling around it appears as though I need libpq.a to link a client app
against and then libpq.dll is only used at runtime. I'll download the full
postgres installer this week and see if the liqpq.a file is included.
Any reason why you're using postgres and not postgres3? Postgres3.pp uses
external instead of linklib and doesn't require libc.
I've also found a regular OS X package (.pkg) for postgres.
Thanks.

Can anybody help us here ?
I actually have it linking on one machine, and not on another but for
the life of me I cannot figure out the difference between the two
machines.
Can we document this somewhere ? When developing programs using
third-party linklibs through lazarus/fpc units - where do you actually
PUT the dll's ?
I am also trying to determine the minimum number of libfiles that need
to be shipped WITH the program - the libpq.dll in the svn tree came
from pgadminIII - as an experiment, but I am affraid that perhaps you
need the full set of libs that are included in postgresql - or at
least a few more of them... but which ones, and where to put them in
order to get lazarus to build with the package installed, and the app
to link on windows ?
/me really hopes for some good advice here.

RE: [lazarus] Debugger on Mac OS X
Today I started looking into the issue of how to store additional version info that could be used to populate a Mac app bundle's Info.plist file. Unfortunately, it appears as though any additional data added to the .lpi file in the VersionInfo section gets deleted the next time it's saved. Shouldn't the Laz IDE roundtrip data it doesn't know about in the .lpi rather than deleting it? By deleting it, isn't that kind of defeating the purpose of using XML for the .lpi? Also, if the value you enter in the Product Version box isn't in the expected format (major.minor.micro.build), this prevents Laz from compiling and doesn't give any error.

You can then change the widget type to gtk, qt or carbon as needed and compile. I don't believe the extra linker switches make any difference if not needed to resolve references for a particular widget set. AFAIK this will only work under MacOSX. We need conditional compiler options. There is already a feature request in mantis. Regarding your 2nd suggestion: It's absolutely critical that the IDE not create a new app bundle each time it compiles. Remember that an app bundle is rarely the barebones folder that createmacapplication creates. It may contain dozens or hundreds of other files - resources, icons, private frameworks, etc. These will likely need to be copied in manually by the developer, but once he's done that the IDE shouldn't delete the app bundle - rather, it should just compile to replace the executable (which is either inside the bundle or outside the bundle and symlinked to it from within the bundle as createmacapplication does it). Agreed. It would be nice if there were a way to set the bundle's Info.plist settings from within the IDE, but this might be asking too much. I believe I wrote up some suggestions related to this and the IDE's Project Options | Version Info about a year ago but don't recall if I posted them on the forum or what. What info is stored in the Info.plist? Currently I use a script file something like my create_app_mac.sh that I run to create the initial app bundle and copy everything needed into the bundle folder (can also do this anytime I need to start over with the bundle). Something like this will probably always be needed for non-trivial projects.

RE: [lazarus] Debugger on Mac OS X
Mattias, I've used the FPC DOM unit to add to and delete from XML files without destroying everything else in the file. Use TDOMNode.RemoveChild to delete a node (for example, VersionInfo). Use TDOMNode.OwnerDocument.CreateElement and TDOMNode.AppendChild to add a node to an existing XML file. It would seem as though the change would need to be made in TProject.WriteProject, which calls CreateClean rather than Create. I believe Create loads the XML file rather than starting a new one the way CreateClean does. My thinking is that possibly the Version Info panel could have a Mac Info.plist button, which would be disabled in non-Mac versions of the IDE. Clicking this displays another dialog with a grid for entering any of the settings for the app bundle's Info.plist file. These would be saved in the .lpi, either as a subsection (Info_plist) of VersionInfo or in its own section. Eventually when the IDE has the ability to create an app bundle folder when it compiles a project, it could use this info to populate the bundle's Info.plist file. Does that sound like a reasonable way to go about it? Or should we not dirty the IDE with platform-specific stuff in this way?

RE: [lazarus] Debugger on Mac OS X
You're right, the Mac Info.plist button should not be disabled on other platforms. Presumably by including Mac (or maybe OS X) in the button label should make clear the target for these values. Speaking of which, it's not clear that the Version Info and Additional Info settings are only for Windows. Even though there's some overlap between Windows version info settings and Info.plist settings, it might not be a bad idea just to duplicate these to ensure that there's no conflict between their meanings! Yes, the Info.plist settings should be managed same as other .lpi settings, perhaps written in TProject.WriteProject? I haven't really studied this code much yet.

I believe Create loads the XML file rather than starting a new one the way CreateClean does. Sorry, maybe I made myself not clear: You are right, that it would be *possible* to keep some user created data. But the lpi file should not use these abilities, because - Lazarus uses an optimized xml reader/writer, that is not capable of all xml things. So the only guaranteed working xml is created by the laz_xmlcfg unit. - The clean up is used to keep the lpi file short and free of waste, so you can be sure, every single token has a meaning. For example if a path name changed the old values will automatically vanish. This way I'm still using some 6 years old .lpi files. - The lpi file content should be completely editable via the IDE. Users do not need to understand the lpi format. - the lpi file content can be exported (publish project). Eventually maybe to a non xml format. My thinking is that possibly the Version Info panel could have a Mac Info.plist button, which would be disabled in non-Mac versions of the IDE. No. All options must be visible and editable under all platforms. Think about cross compiling or a non mac developer that must review/fix the mac port. Just give a hint, that these option are only valid for the Mac platform. Clicking this displays another dialog with a grid for entering any of the settings for the app bundle's Info.plist file. These would be saved in the .lpi, either as a subsection (Info_plist) of VersionInfo or in its own section. A grid is a good idea. But IMHO it should be stored in the lpi as any other project data via the TXMLConfig, not as raw xml. Eventually when the IDE has the ability to create an app bundle folder when it compiles a project, it could use this info to populate the bundle's Info.plist file. Maybe some values like title can be shared between platforms. So the Info.plist will be created from many values. Storing the Info.plist as raw xml will make it harder to do that.

Hi All, I'm happy to announce that OutKafe 5.1.0 is now available for download from http://outkafe.outkastsolutions.co.za. The new version is primarily a bugfix release containing fixes for many critical bugs and a few multidistro compatibility improvements, here is the changelog: 2007-06-02 Ported application to GTK2 Fixed multiple crash bugs in counter Fixed layout and accounting bugs in admin system Fixed counter-window button layout bug Fixes for several LTSP related bugs. Better handling of remote admin functionality Fixed a bug with number entry in sell-time dialog. 2007-05-21 Added pid-storage support to outkafed Enhanced boot scripts to use pid-stored value native installer support for chkconfig or rc-update when available I also made significant progress on the promised win32 client - but I simply couldn't get it to quite work. At this stage though, it's far enough complete that I am putting out a call for a volunteer who can help me finish it off. Anybody with experience of lazarus/delphi on Win32 who is up for helping me maintain the win32 client please mail me - I would welcome all assistance with this part, experience with postgresql will be useful but not critical (everything is pretty abstracted).

Heh, fair enough - though I thought I basically had :p Where does OutKafe run? Does the cafe have a network server or something that the cafe's computers are hooked up to? OutKafe comprises basically three parts (this I KNOW is on the website). The postgresql database server does all the network serving, so I don't code any of that, I just interact with it. OutKafe has: 1) A daemon which counts down time on logged in accounts (it's done centrally for security reasons) 2) An administration tool which allows the icafe operator to sell time, create user accounts, reset passwords, define offers etc. 3) Client programs which let a user log in, counts him down and logs him out again. Currently only the Linux client is in a working state. The win32 client is very close - but I need somebody with genuine windows coding experience to help me finish it. There is also a WIFI client very similiar to what you describe below, but that is not very complex and at this stage barely started. I guess I'm not familiar with Internet cafes like this. Usually here the cafe has wireless and you get a login code for your laptop when you buy a coffee. That is common in some countries, here in the developing world the kind with computers hooked up that you buy time on is still very common, for many people such outlets ARE their offices. Having a GPL'd tool to manage them is an important (I believe) way to ensure software freedom in the developing world. OutKafe is the only such tool out there (OpenKIOSK is only partially free software - I'm not aware of any other free projects that are still actively developed though there are quite a few proprietory ones like smartlaunch). Of course the whole thing is also done in Lazarus and is one of the oldest continuing lazarus developments (the original app was started in November 2002, the Lazarus website carried a story on the 3.0 release in May 2005).

RE: [lazarus] Debugger on Mac OS X
Felipe, Good suggestion. By making it a compiler option, it could be unchecked if you don't want the default barebones app bundle to be created. For experienced developers, this would probably be what they would want since they would probably have to delete the barebones app bundle in order to use their own Info.plist, etc. However, by making it on by default, it would mean that new developers wouldn't have to worry about figuring this out.

RE: [lazarus] App bundle and icons for x11 apps on macintosh
Felipe, You should be able to create an app bundle for Lazarus, even with its dependence on needing X11 already running. See http://wiki.lazarus.freepascal.org/OS_X_Programming_Tips. I had this working at one time. Note that you'll probably want to go a step further and try putting all of the Lazarus source and other files inside the bundle folder. That way you'll be able to drag and drop Lazarus anywhere you want on your computer. An app bundle is what's known as an opaque directory in that it appears to the user in Finder as a single file, without its .app extension. However, it's really just a normal folder. It's important to remember that when constructing your app bundle, you're also readying it for distribution. For example, you can drag and drop the app bundle anywhere you want or copy it to another computer. Or you can turn it into an installer package (.pkg) with PackageMaker. This is a different approach from, say, Windows, where you build your application and then use a separate program (e.g., Inno Setup) to select all the various files, often from diffeent locations on your computer, that need to be rolled into the installer, and also specify where all these files will be installed on the target computer. With OS X, you're both building the app and creating the final installation footprint at the same time. Really a lot more logical way of doing things. I think that moving to an app bundle for the IDE really should wait for a Carbon-based IDE. That would eliminate the need for X11 or GTK to be installed and would make Lazarus a true Mac app that's easy to install (I suspect most newcomers to Lazarus on OS X just give up when they see how complicated the installation is). Once a Carbon-based IDE is available I doubt if any Mac user of Lazarus would ever install GTK, except perhaps out of curiosity. Also, since you have an Intel Mac, you should be able to install and run the PowerPC version of FPC and Lazarus too and create PowerPC executables without cross-compiling. One issue would be figuring out how to install two versions of FPC since these file locations are kind of hardwired right now. Perhaps FPC could be put in an app bundle too or made more relocatable than it is now. If you're able to compile PowerPC executables maybe you could look into creating a universal binary app bundle that contains both the Intel and PowerPC executables and compiled units. If that's possible then Lazarus could theoretically be distributed as a universal binary instead of separate versions for Intel and PowerPC.

RE: [lazarus] Debugger on Mac OS X
Good point. But if the linker on other platforms complains about the OS X specific switches, you should be able to uncheck Pass Options To Linker box, correct? Here's the reference for what can go into the app bundle's Info.plist file: http://developer.apple.com/documentation/MacOSX/Conceptual/BPRuntimeConfig/index.html Some of the settings in Info.plist kind of overlap with Windows-type version resource info, hence the idea that maybe some of them could be set in Project Options | Version Info, although this would require a way to define any sort of string the way you can in Delphi, not just the limited version strings that it allows now.

I don't believe the extra linker switches make any difference if not needed to resolve references for a particular widget set. AFAIK this will only work under MacOSX. We need conditional compiler options. There is already a feature request in mantis. Regarding your 2nd suggestion: It's absolutely critical that the IDE not create a new app bundle each time it compiles. Remember that an app bundle is rarely the barebones folder that createmacapplication creates. It may contain dozens or hundreds of other files - resources, icons, private frameworks, etc. These will likely need to be copied in manually by the developer, but once he's done that the IDE shouldn't delete the app bundle - rather, it should just compile to replace the executable (which is either inside the bundle or outside the bundle and symlinked to it from within the bundle as createmacapplication does it). Agreed. It would be nice if there were a way to set the bundle's Info.plist settings from within the IDE, but this might be asking too much. I believe I wrote up some suggestions related to this and the IDE's Project Options | Version Info about a year ago but don't recall if I posted them on the forum or what. What info is stored in the Info.plist? Currently I use a script file something like my create_app_mac.sh that I run to create the initial app bundle and copy everything needed into the bundle folder (can also do this anytime I need to start over with the bundle). Something like this will probably always be needed for non-trivial projects.

Please review before applying this patch. Looks ok, the only problem I see is that, currently the property default for GridLineWidth is set to 1, but as grid doesn't set the GridLineWidth at creation it takes value 0, this value is stored in lfm file for every project that uses grids (TDrawGrid and TStringGrid) previous to this patch, nobody reported this bug before I think because it didn't have any effect. But now people will find suddenly their grids doesn't have gridlines, the fix is just to change the value to 1 in object inspector and save the form. This have to be done anyway, so I applied the patch in revision 10961 and fixed the grid lines in lazarus sources in revision 10962 This is not a full implementation but rather a quick cosmetic implementation. The difference is that this patch changes the grid line width for painting only, but not the actual offset or regions of the cells due to the change in Grid Line Width. No problem, it's the way it works currently. Fixed columns don't draw the grid lines thicker than 1 (not sure if this is correct behaviour). I don't think it is, I will try to fix it. At least with this patch you are now able to hide the grid lines (GridLineWidth = 0) when required. This is the main feature I was missing to get my custom component to work. I agree it does a better work than the current methods. In the Delphi implementation, the cell size will stay the same even though the grid line width increases. Delphi does cause a very strange effect (I think it's a bug) when the GridLineWidth is set to a negative values. I don't think Lazarus needs to copy that behaviour so the lowest value the GridLineWidth will go is 0 in the LCL. I agree, we will have to change this so it becomes more delphi compatible anyway, but for the moment I think it's ok as is. -- Graeme Geldenhuys Thanks. Jesus Reyes A. __ Correo Yahoo!

RE: [lazarus] Doing the Delphi 6 Text Editor Tutorial in Lazarus?
Do you want to (a) create RTF files programmatically and/or display RTF files from your program or do you want to (b) allow your users to have a simple rich-text editor in your program. You can do (a) now in a cross-platform way with the FPC rtfpars unit and an external word processor. -Original Message- From: Graeme Geldenhuys [mailto:[EMAIL PROTECTED] Sent: Thursday, April 05, 2007 3:14 PM To: lazarus@miraclec.com Subject: Re: [lazarus] Doing the Delphi 6 Text Editor Tutorial in Lazarus?

It doesn't show up in Kylix because there is no equivalent in the QT widget set. The WINE guys I know under Delphi it's a wrapper for that .dll, but why couldn't Borland just write one from scratch for Kylix? The same goes for Lazarus. Strangely enough, developers come up with all different kinds of components, but nobody every bothers to write a RichEdit component from scratch. That's why I'm asking if it's such an impossible thing that nobody can do, except the hordes of Microsoft employees. -- Graeme Geldenhuys There's no place like S34° 03.168' E018° 49.342' _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
