Re: [lazarus] Behavior of ClientToScreen in scrolling windows across different widget sets
Luiz Americo Pereira Camara wrote: While debugging scrolling bugs in LCL i found that ClientToScreen acts differently according to the widget set. These are the behaviors: 1) The returned value is related to the actual position, i.e., it does not consider the scroll offset. If you pass Point(0,0) the value will be the same regardless of the scroll position. (Gtk1) 2) The returned value is related to the virtual position, i.e, it takes into account the scroll offset. If you pass Point(0, 0) the value changes inversely to scrollbar position. (Gtk2) 3) The returned value is related to the virtual position, i.e, it takes into account the scroll offset. If you pass Point(0, 0) the value changes the same amount of scrollbar position. (Win32) 4) Nothing. Qt has no visible scrollbars so... Notes: Delphi does the same as (1)/Gtk1 Not really, internally Delphi does it like 2. All controls are moved. (3) is clearly buggy. Between (1) and (2) is a design decision. We started like delphi, move controls and report corrected values when asked. However this aproach is very inefficient on all widgetsets except win32. So the new approach is that controls stay at their position and only the virtual parent gets an offset. This means that the top/left of a control on a say scrollbox are allways the same, an offset to the virtual parent top/left. So now ClientToScreen. The top/left of a scrolled control needs to get a scrolled offset, so that is reflects the real position relative to the real parent of the control. Marc Attached is a patch that makes win32 acts like (2)/gtk2. It changes the offset signal when calculating the LCL bounds. With the change it becomes consistent with the TCustomGroupBox signal convention (LCL bounds at Right/Down of win32 +, at Left/Up -). It also fixes the scrolling paint and setcursor of non TWincontrol.

It's just one of the 65000-plus known bugs of Windows. This is not only unneeded, but not even thought of in other OS's. Only in Redmond such a thing can be considered normal. Dont make quick decisions :) Some qt widgets also lack from inability to change few properties after their creation. For example QRubberBand cannot change its shape after creating. Some gtk properties also cannot be set after realizing of widget. For example you cannot ask gtk widget to create/remove gdk window after widget realizing. I expect carbon can have own examples. So in 2% of cases RecreateWnd is needed, That is exactly why I removed recreatewind form twincontrol. Most (if not all) widgetsets needs a recreate for the one or the other property (you cannot add columns to a listview in gtk for instance). However this recreating is not always for the same property. So recreate will work, but in most widgetsets it is unneeded. but indeed its add headache. For the LCL itself it doesn't since all logic to create a handle is already present.

That is why there different widgetset backends too, not just to create different widgets, but also to make them behave consistent. But how do you know if that's not maybe the native behaviour of the underlying widgetset? I think this is what Giuliano was trying to say or assumed. Don't assume, research. Not convinced, GTK1 implementation of TMemo InsertText: if NewTextLength - CutLength 0 then begin gtk_editable_insert_text(PGtkEditable(widget), char, NewTextLength - CutLength, Position); end; g_signal_stop_emission_by_name(PGtkObject(widget), 'insert_text'); GTK2 implementation of Tmemo InsertText: if NewTextLength - CutLength 0 then begin gtk_text_buffer_insert(TextBuffer, StartIter, TheText, NewTextLength - CutLength); end; g_signal_stop_emission_by_name(PGtkObject(Textbuffer), 'insert-text'); GTK2 scrolls in order to show the text just inserted, GTK1 doesn't. Convinced now? Convinced, that you did some research: yes. Convinced, that you did enough research: no. Convinced, that scrolling the text after inserting text is agains the native behaviour of the native widgetset: no, not at all. IMO, the LCL should give the application users a native look and feel using the native components as much as possible. At this moment, we are failing in this respect with our current implementation of the Treeview and the Toolbar, for example, since they are drawn by the LCL and not by the widget set. This will probably change in the future, keeping the current Treeview as TLCLTreeView or something like that. The LCL should give the application developer a consistent (VCL compatible) interface to accomplish that. In this case when you append or insert text the application developer expects that gtk1 and gtk2 (and all widget set) do the same thing: either scroll to end or leave the cursor on the current position. I don't think that this scrolling (or not scrolling) can be considered intrisically part of a widget set. Suppose we decide that a widget should scroll when adding line to a LCL TMemo should scroll that line into view, then all widgetset should do that. The gtk1 implementation should add extra code to accomplish that. Suppose we decide that a widget should not scroll when adding line to a LCL TMemo should scroll that line into view, then all widgetset should not do that. The gtk2 implementation should record the current position and add extra code to accomplish to keep the cursor on the current position. I would sugest to fix the gtk1 implementation. I hope this is clear now, if not, feel free to ask for clarification. What you say is clear, and I do agree with you. LCL should provide consistent behavior across widgetsets. Maybe I can disagree on what's the best way (i.e. minimum work-best result) to achieve this result, but that's another matter, and it's up to you, after all. I can just provide my point of view as a contribute to the discussion. But when I see other developers say exactly the opposite, i.e. that LCL should provide native behavior, and maintain that some properties shouldn't be implemented in some widgesets because they're not natively available, then I get confused. Native widgets native behaviour. The LCL adds functionality to native widgets so a LCL user wil benefit from that and will het the same behaviour. (also the VCL added some different behaviour to win32 widgets) On case by case base it is decided if a certain behaviour is compatible with delphi, is better than delphi or is behaving like most widgetsets. For scrolling after a line is added, I don't know. Personally I hate it when a memo gets updated and I want to read the contents the same time.

Re: [lazarus] Default target OS/CPU for projects ?
Michael Van Canneyt wrote: Hello, How does the IDE determine the target OS/CPU if none is specified for a project ? Apparently, it takes the same OS/CPU combination as the one the IDE itself was compiled with. In my opinion, this is wrong. It should see what compiler was selected, and use the OS/CPU combination that this compiler reports. Specifically: - I use the i386/Linux IDE. - No target OS/CPU has been specified. - I select the ppcx64 compiler in the Environment options. - The IDE constructs all paths with units/i386-linux. - Recompile IDE. Of course, compilation fails. All goes well for the LCL/IDE because the makefile detects that it needs x86_64-linux, but compiling the packages fails, because the IDE constructs all paths with 386-linux... The same is true for any other project as well, of course. I think that this behaviour should be changed to the same behaviour as used by the makefile: detecting the default OS/CPU of the used compiler. Or that at least there should be an option to allow the choice between: - Always use IDE CPU/OS combination - Detect compiler CPU/OS and use that. Opinions, comments ? IIRC, this was a todo to base CPU/OS on selected compiler.

A lot of time ago. I know, it's voluntary work, everybody does its best. We take what's available, and thank. But please don't tell me that gtk2 can be taken in consideration for anything else than a specific project carried on by a Lazarus developer, who knows enough the internals to fix the widgets he needs. And what do you plan to do about it? Try and convince Lazarus developers to follow a route which makes it possible for a lot of people like me to actively contribute instead of just feeling helpless and whine. What route do you suggest ? What I mean is very simple: I have to get to work at 7:30 and come back at 21:00. Why would I use my spare time to hunt for the endless, arbitrary bugs in the gtk2 interface? And my experience with the gtk/gtk2 interface is enougth to say it ain't particularly fun to work endless hours to fix small bugs on that spaguetti code, which often ends up without any fix. That's the point. Attempting to fix z-order in GTK2, which is a minimum requirement in order to make a real world application work, requires to study gtk2 in detail. Whatever model you come up with, be it native contols or customdrawn controls, as soon as there is a bug on OS/widget level, you need to understand that level. Moreover you may be forced to modify something in LCL, which will doubtless break gtk1, Qt, Carbon, windows, WINCE etc. (I see it happen every day) So you must study gtk1 in detail (loss of time because gtk1 is long dead), Qt, Carbon (I don't have a Mac), windows API's etc. It's above me. And apparently above Lazarus team. Now you're taking the extreme route, this doesn't happen that often. However if there is a bug in the LCL it needs to be fixed. It's to noones advantage that every widgetset has to work around tose bugs. Still we are happy to receive patches aginst gtk2+lcl in this case. It may only take longer before things are applied since more ppl are involved to fix other widgetsets. That's why I claim that the native widget route is a dead end. That's your claim, not ours. If the bug is annoying you, then *you* should do something about it =) If all users use the approach: Oh, I'll test now and wait 3 months and test again, then they are all risking that in 3 months there won't be any change to what they wanted changed. See above. If something is within my reach, I attempt to fix it. If it's above my reach I can only whine. You can also help with small testcases and such exactly pinpointing the problem. Whining won't help anyone, only you loose. (I will certainly not inspire me to help you) If you don't plan on doing anything about it, then I say it's not that annoying for you, because it's not annoying enougth to make you do something about it =) What *I* plan to do is to take alternative, more viable routes, but it's a pity.

And we could do things other widgetsets could only dream of. And porting to OpenES would be easy, too. Stupid Lazarus developers. Now we only get this sucking Win API, GTK1, GTK2, Carbon and QT. Nothing really works and all is full of bugs. If we had used OpenGL, then we had to create out component framework first. Keep in mind, Lazarus is primarely focused in using *native* components and I repeat it again *native* components. OpenGL is *not* native. EOD.

If it uses accesses the terminal directly, there is little you can do, except opening the terminal and trying to control it yourself, but that's outside the scope of TProcess.

My question is when I try to use the code in my project using Delphi compatability mode, I get the error listed below... var lRow : Pointer; ScanLineImage : TLazIntfImage; begin for j := 0 to Height - 1 do begin lRow := ScanLineImage.GetDataLineStart( j ); i := 0; while ( i Width - 1 ) do begin PByte(lRow)[i] := 0; // Error : Array type required end; end; end; Why and is there a fix for this? in objfpc mode you can access any typed pointer as an array like: var p: PWord; begin ... p[someindex] := 12345; Should I define lRow as a PByteArray? In delphi mode, Yes. Unless you want to compile this in Delphi, there is no reason to use delphi mode. You can, if needed, use a different mode per unit.

Re: [lazarus] last svn problems under fpc 2.0.4
Giulio Bernardi wrote: A little bit off topic... but does lazarus still need to support fpc 2.0.4? AFAIK fpc 2.2.0 runs on all platforms supported by lazarus... or am I missing something? nope. 2.2.0 fails on OSX when sources are located on a casesensitive filesystem. So initially I plead for 2.0.4 compatebility. However 2.2.1 has solved this, so for me there is no reason that there *must* be a 2.0.4 compatebility. I've to admit that after my last changes I forgot to check if 2.0.4 still compiles., maybe causeing your problems.

Re: [lazarus] Laz / Fpc function listing
James Chandler Jr wrote: I've been using Delphi Pro from version 1 thru 2006 (skipped over a few versions). I really like Lazarus, especially the crossplatform aspects. Strangely, have been using Delphi Help (very well put-together) for most Lazarus lookup. I first check on the function (easy to find) in Delphi help, then do a file-search in the Lazarus folder to see if the name exists, and double-check to lookup any differences which might exist from the Delphi incarnation. But a lot of times, you have to know a little bit before you start looking in Lazarus. Some fpc/lazarus stuff is well documented and easy to find 'on the surface'. Other stuff is well hidden. A trivial example-- Try doing a google search or search the fpc/lazarus websites for documentation on PtInRect. Maybe ya'll have different search tools that recover lots of references, but if I don't know what pas/inc file holds PtInRect, I can't find any easy-to-retrieve info with a web search. I knew I needed PtInRect, but didn't know if Lazarus had one, and didn't know how Lazarus spells it. Ah.. this is a common issue. While a lot of ppl think all routines you use in delphi are from delphi, it in fact isn't. You have the ones made by Borland which you will find in the rtl or vcl and you have the translation of windows api. PtInRect is such function. It is defined in the Windows Unit. Since Lazarus is crossplatform, it doesn't have a windows unit. Most common used winapi functions you normally would find in the windows unit are implemented in the LCIIntf unit.

OK, I couldn't remember. I only remembered the alignment issues florian and I had when getting lazarus-sparc to work Working from memory rather than notes a form icon works OK on Win-32 and x86-Linux except that it might get turned upside-down (that might be specific to BMP rather than XPM). I only know that this is the case for lazarus running on wine (and I know the location what causes this, I only need to do some checks). However it causes various exceptions in the IDE on SPARC to the extent that a form won't load into the designer, although compilation works and the result is runnable. I got as far as suspecting that there were related problems. Lazarus should run on a BE machine (tested on my ppc mini mac) I must stress that the above might be unreliable since I'm not working from a methodical set of experiments and notes, it's something I hope to get back onto as soon as I have time. :) Maybe I should find some time to fix my disk issue and fireup my sparc Marc _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

I know for some parts I wrote myself that they are pretty similar to the way delphi had implemented them. Most smaller implementations of a given method can only be done in one efficient way. So it make's sense that they look equal. Note: This tool is automated and fast. I'm sure _not_ everything it detects are actual copied code, but it might be worth our while going through it and verifying the code marked. Rather be safe than sorry. Plus we can then say we tried to remove infringed code from our side. True. The most used pieces of delphi code I recognize, but not the from the bit more exotic areas. We have also had one or two cases where code appeared to be similar, but only had a (important) difference in details.

Re: [lazarus] ParentWindow
Christian Budde wrote: Ok, just for the records: I tried to do it with TWinForm.CreateParented(ParentWindow: hwnd), but I get an access violation. So that does not work. I think ParentWindow is very widgetset specific (see below). Probably it will work cross platform very limited. Ok, thanks for the information. I'm willing to find a cross platform solution, so I don't necessary need to go that ParentWindow road. Solution: It is probably easier to create a wrapper TWinControl / TCustomForm with the ability to use the foreign Handle. I just had a look at the wincontrol.inc and I already found this: {-- TWinControl CreateParentedControl --} class function TWinControl.CreateParentedControl(ParentWindow: hwnd): TWinControl; begin // ToDo Result:=nil; end; Is this what you thought of? I mean it's still pretty ToDo, but I guess the structure is already there. Now all I need to do is fill it with live. Any ideas? The main reason it exists is delphi compatebility. Using this function instead of using windows.SetParent has the advantage that the VCL/LCL knows that the parent is not a VCL/LCL control so it can do special things. I think on win32 for sure and on X or OSX it is doable. However I think it will take loads of time to debug the LCL prevent it to assume that a parent always is a LCL control. And the result will always have less functionality that when it has a real LCL parent. Even in delphi this is the case. So it is a lot of effort for something with limited functionality and limited use. I rather spend my time on other things.
