Re: [Lazarus] Ideas for improving lazarus.dci code templates
Zitat von Graeme Geldenhuys graemeg.li...@gmail.com: Hi, Over the years I have noticed some shortcomings in the lazarus.dci handling. Here are some of my ideas. Please comment on them before I create official feature requests in Mantis. * Lazarus should have seperate .dci files. One for custom user settings and one which contains the default .dci settings. That way if new default settings get applied to the lazarus.dci file, all users get it without the next Lazarus update. The lazarus.dci should live in the Lazarus install directory. Then we should have a user.dci in the profile directory. * If the user customizes an existing (default) code templates, they should be added to the user.dci file and override the default one. +1 for overriding. About the default file: The defaults are compiled into the IDE. The IDE has a 'secondary' config path, where pool admins and package maintainers can put default configs. A secondary config file is copied to the user's config directory, iff no user config exists. i.e. the configs are not merged. If no primary and no secondary config exists, the IDE uses its defaults. So there is already a chain of defaults. I think adding a further default file only complicates things and will not solve much. Why not use the same as for the highlighters and key mappings: The IDE first loads the defaults, then merges the user config (additions, replacements). Because you can not delete a default code template, a 'disable' option is needed. * This design which be extended even further to have language specific .dci files. Instead of lazarus.dci, rather have the following: - objectpascal.dci - java.dci - html.dci - javascript.dci etc... So as the IDE opens a file, lets say for example a index.html file, then the default code template for that file will be html.dci The synedit editor available on sourceforge already includes a lot of language specific dci files. I post those to mantis if needed. Ok. Add an extra .dci for all languages (copyright templates, todo comments, ...). * Why doesn't the default lazarus.dci contain a repeat...until' code template. I always add it myself though. Name? rep? The templates use the first unique prefix, so 're' will automatically work. * Maybe project specific code templates could also be an option. I'm not sure is this is really relevant, but it might be handy. For example, I develop many tiOPF (Object Persistent Framework) applications. I have a lot of code templates for such projects. But if I work on a quick console application, those code templates are not needed. Some maybe Lazarus Packages or Project Options could contain an entry for project or packages specific code templates. Project Options is probably the better option. IMO this is only useful for power power users. Your thought? Any new suggestions?

Re: [Lazarus] Live Templates
Zitat von Lee Jenkins l...@datatrakpos.com: Graeme's recent post made me wonder if there is been work or talk of work on implementing Live Templates like Delphi has? Yes. 1. Lazarus will not support the Delphi syntax, because Lazarus already supports code macros. There are already some code macros using the codetools. 2. auto complete without pressing a short cut already works for return, space and word end. Some code macros are needed to fine tune adding text if parts of the template already exists (for example auto complete 'begin' after pressing return). But this is stuff for another thread. 3. templates with parameters: editing the parameters directly in the source editor (synedit) without a dialog. synedit needs a further edit mode for marking and editing several places in parallel. Martin has already implemented marking several places. I guess he can also create a plugin/extension/mechanism for the needed edit mode. When this is done, I will be glad to implement the rest. This edit mode is also needed for in situ rename. I imagine that that kind of behavior is a bit of work to implement. Yes, but I bet Martin has already some ideas for synedit.

Do you mean the shortcut doesn't work or the actual procedure List dialog doesn't work on all widgetsets? Alt-G does not work. With other short cuts it works. Since I switched from GTK1 to GTK2, procedure list doesn't work as well. I think it's due to a bug in GTK2 listview, but I haven't investigated further. To reproduce: * Alt-G (or whatever your shortcut is - mine is always different) to open Procedure List. * Start typing partial method name. * Now press Down Arrow. This should put focus in first item in listview, but it doesn't. :-( This used to work under GTK1. Other differences between Procedure List and Code Explorer. * Procedure List jumps to Implementation section. Code Explorer to Interface section. Yes. And this is needed. Maybe jumping to implementation can be added with a modifier key. And an option can be added to toggle With/Without modifier and Interface/Implementation. * Procedure list can filter by Class, non-class or All methods. I don't think Code Explorer can. Very easy to implement. Make a proposal for the gui. * Procedure List can filter by method starting with text or method containing text. Not sure what Code Explorer does. containing * Procedure List, when launched puts focus where it must be - in the filter edit box. Code Explorer - I have no idea where the focus is, I think the treeview (filter box might be a better idea). Patch is welcome. * In procedure list, when you press Enter to jump to a method, Procedure List closes and gets out of the way. Code Explorer hangs around taking up screen space. code explorer is a floating window, normally visible all the time and placed left or right of the source editor. So yes, there are plenty to discuss before any merge is to be considered. Please. All floating windows should be dockable. We have already a docking Excellent! Can we enable docking already in Lazarus - even though it isn't saved and restored between sessions? 1. afaik dragdrop docking does not work on gtk. Only docking via menu item. 2. docking without restore is as useful as a lazarus without projects. Maybe some predefined sets can be added until someone finishes the restore of one of the docking managers.

Also I can't see how those 3 relate at all. They can use the same Search Results window for their output. That window will know what to do (show related place in source code) when an entry is clicked. I don't see how. Find in files shows simple text and identifier occurences. Find in Files and Find identifier references already use the same window. Messages shows several types of messages from compiler, make, codetools and allows to quick fix these. It is planned to allow filtering and sorting. Code observer shows places that might be interesting for code tools. It is planned to add a second treeview to the code explorer as gui for the codetools. Code explorer has lots of short items (more height than width), the other two need more width than height. I see no problem to page-dock messages and find in files, but implementation and usage are too different to marry them. Anyway, for that lets wait for docking. Some notes on docking: The Messages and Search Results can be docked to the IDE main window, eventually by default. The docking of forms is unsupported on many platforms, due to the different management of controls (widgetset) and windows (window manager). So all dockable windows should contain one single component for their entire content. (or the forms should float as clients of a floating form). This requirement lead me to another suggestion: When one or more forms are docked into another window, their UI (menus, toolbars...) could be added to the dock host form's UI. Just an idea... AFAIK merging menus is a very old Delphi feature. There are some starts in the LCL already. what about: - keybard layouts? - Menu layouts? Some visual design for toolbars (and menus) would be nice, as in the Delphi IDE window (configure by dragdrop from the list of available options to a toolbar).

Why do you want to give the controls names? Names are convenient to identify floating windows (label title bars) or docked controls (dock header label), and are required for the de/serialization of docking layouts. But you are right in so far, as dynamically created controls are of little use in the recreation of a docking layout. In this case the names should be hardwired somehow, so that the appropriate controls can be created from the stored layout. I'll have to re-think this issue in the implementation of multiple editor windows and the related forms. Then e.g. the code explorer windows etc. must be linked to the edit control in their dock site, regardless of their name in creation order. Welcome to the complex world of layout restoration. ;) Just an idea: The anchor docking manager has one component per docked control. It allows to set a unique name and will use by default the component name. The manager will resolve conflicts by appending a number. The user can set the name via the designer and a translated name for i18n. Mattias ___ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus

2009/4/9 Mattias Gärtner nc-gaert...@netcologne.de:
As I already written some time ago, the solution is to introduce a
hint/warning for the circular dependencies in implementation sections.
This hint should probably be disabled by default, for compatibility
reasons.
Yes, a hint would be nice.
But a hint won't be enough. It would go unnoticed too easy.
This is another important problem. Easily unnoticed hints are just useless.
There are two related causes here:
1) The message window interface of Lazarus is currently very weak.
(And it hides most of the hints by default, which I consider a bug in
design).
What hints are hidden?
This interface is one thing I think is worth borrowing from Visual Studio.
Can you give more details for the people who don't know VS?
2) The compiler produces _many_ extraneous hints, which is very harmful --
it is impossible to produce hints-free code, so new hints has much
more chances to go unnoticed.
True.
First point is IMO of patches welcome category (and perhaps I will
provide some,
but don't count on that), but the second one is more fundamental.
There are two main sources of harmful hints now:
1) Parameter unused.
This is by far the main culprit. There are many cases when parameters are
unused deliberately -- e.g. basic implementations of virtual
functions, most events etc.
OTOH, the hint is not _entirely_ useless and can in some rare cases
point to a real bugs.
The solution is to enable per-variable hint suppression. It is done in C/C++
by omitting variable name, but I think a better way would be a
compiler directive.
I see two variants:
a) procedure TMyForm.Button1Click(ASender {$UNUSED}: TObject);
b) procedure TMyForm.Button1Click(ASender: TObject); {$UNUSED ASender}
The first one is slightly messy in case of many unused arguments,
while the second one avoids duplicating their names, so I am not sure
which is better.
Implementing either of them will fix the problem.
That's pretty much what I purposed a long time ago. I even implemented it once
via IDE directives.
But the code gets ugly and it worked only in lazarus.
A compiler solution with some synedit sugar might improve this.
2) Uninitialized variable for auto-initialized strings.
See http://bugs.freepascal.org/view.php?id=0013341 and
http://bugs.freepascal.org/view.php?id=13370.
Both issues were resolved as won't fix which IMHO was done without
considering full picture.
... or because they considered an even bigger picture than you.
Here is my argument:
There are two possible approaches to non-initialized warning:
a) Do not guarantee anything about non-initialized variables, complain
on their usage.
This is C/C++ route. It is not entirely consistent there as well
(global variables of simple types
are still auto-initialized to zero), but that is their problem.
b) Makes some guarantees about variable initialization and complain only for
the variables which are not initialized automatically. This is Object
Pascal/Delphi route.
It does not warn about global variables, object fields, strings and
interfaces since they are guaranteed
to be auto-initialized in a consistent way (and programmers rely on that).
FPC seems to take the third route -- it inconsistently warns[1] about
globals, strings and interfaces but
not object fields. This is the worst of both worlds and should be
fixed one way or another.
Compatibility and language tradition dictate retaining
auto-initialization, but I am not principle
opposed to removing it -- this, however, should be a loudly declared
lack of feature/incompatibility
and have a good reason.
Wrong list. Lazarus will not change the compiler.
[1] FPC issues this warning even in Delphi mode, which is an outright bug.

Re: [Lazarus] Define Symbols in SynEdit
Zitat von saeka saeka...@gmail.com: Hello, developers. SynEdit.pp source code has a lot of 'SYN_MBCSSUPPORT','SYN_LAZARUS'. It seems to be SynEdit was compiled by defines SYN_MBCSSUPPORT originaly but now, that is undefined by SYN_LAZARUS.$B!!(B(in SynEdit.inc) SYN_MBCSSUPPORT is defined by supporting MultiByteCharacterSystem on FarEastAsian Windows, but MBCS is not equal to UNICODE. Now, SynEdit in Lazarus is working at UNICODE, ( Its very nice for us.) and SynEdit in Lazarus is highly customized for Lazarus and FreePascal. I have created patch on released version 0.9.16-0.9.24 to Japanese Community in which enabling SYN_MBCSSUPPORT. (http://sourceforge.jp/projects/freepascaljp/releases/?package_id=5278) Now, that is not smart way after 0.9.26, I think. In Unicode, no additional defines needed in handling character. How about delete symbols, and delete IFDEF codings , if it will not be used in the future ? (SYN_MBCSSUPPORT, SYN_LAZARUS, and defines about delphi version) They were kept to eventually merge the changes to synedit. But the differences became too big, so it makes no sense anymore to use syn_lazarus. They can be removed. Martin already started to clean up the code.

Re: [Lazarus] How to query Enabled/Disabled component state?
Zitat von Graeme Geldenhuys graemeg.li...@gmail.com: Hi, Something weird I just noticed. I have not tested this under Delphi 7, but I have tested it with Lazarus GTK1 and GTK2 widget set. See attached image to help explain If I do Panel1.Enabled = False, all components are disabled (visually). This is what I expected. But if I now query Edit1.Enabled, it returns True. Also if I query CheckBox2.Enabled it also returns True. Is this a bug? For some reason I expected all child components to be Enabled = False, because that's what they are. Once Panel1 is disabled, I cannot set focus or interact with any child components. They are even painted in disabled state. How do I pragmatically detect if a component is really enabled or disabled? Seems that the logical way of quering the component's Enabled property gives false information. Most LCL properties are relative. Left is relative to Parent, Visible hides all childs too, etc. As Michael said: Use CanFocus, which uses IsControlVisible and parent enabled. Use IsControlVisible to check whether a control is visible on the form. It checks parents and things like multi pages. It does not check whether the control is clipped. There are almost always exceptions to the rules. It depends on what you want to achieve. Where is a good place to document this?

Zitat von Hans-Peter Diettrich drdiettri...@aol.com: Mattias Gärtner schrieb: Maybe I misunderstood your proposal. What parts of TWinControl should be moved to TContainerControl? Do you want to move the ControlCount and Controls properties to TContainerControl? Yes, all the child control related stuff. I'd move that into the LayoutManager, and redirect all related methods and properties to that helper object. Then the LayoutManager is as exchangable as the DockManager. What about TControl.Parent? It will be of type TContainerControl, of course. I admit that the tests for TWinControl have to be revised accordingly, but there remains more to do. E.g. it's nonsense when TWinControl redirects docking and other messages to TControl, which then again delegates the job back to its own TWinControl parent. All that docking and child control handling stuff should be entirely removed from TControl, and also from TWinControl, and instead should be moved into the layout and docking helper objects. I'm just about to find all that stuff, and to implement a direct connection between e.g. TDragManager, TDockPerformer, and the DockManager. The legacy interface of all classes can survive that update, the revised methods only will redirect the tasks immediately to the final worker object. These are highly desireable changes, regardless of whether we introduce a new layout layer class or not. We might use conditional compilation, so that in case of trouble the old class tree remains intact, for debugging and as a last resort in case of trouble with legacy code. IMO we should cut some of the old trees, in order to see the wood for trees again. First of all: Yes, that would be better from object oriented point of view. But: At least 90% of TWinControl is about its child controls. The rest is mostly key, mouse and focus handling. I guestimate, TContainerControl will have about 1-3kloc code, 500loc will stay in TWinControl and the remaining 4-6kloc will go to the new docking/layout classes. There is no question, that such a big change is Delphi incompatible. The question is how much: - A lot of code (outside the LCL) relies on the fact, that AControl.Parent is a TWinControl and has a handle (exact: can have a handle). The compiler will not find all places that needs to be fixed. For example: procedure RecursiveCall(AWinControl: TWinControl); begin for i:=0 to ControlCount-1 do if Controls[i] is TWinControl then RecursiveCall(TWinControl(Controls[i])); end; This recursive call won't find all children anymore. So all users have to check every place manually, where TWinControl is used and maybe replace it with TContainerControl.

Re: [Lazarus] Vote for Property Editors to stay on top
Zitat von Leslie Kaye les.k...@couchmansfarm.plus.com:
I write to canvas your support for the idea that property editors should
stay on top.
In Delphi property editors stay on top so that for instance you can have
an ActionList editor open and continue to work on the source code editor
underneath.
In Lazarus property editors are initially shown but soon become buried
under other IDE windows so that either they are difficult to find or you
forget them all together.

Leslie
Example for Collection Editors: code should be modified in
/lazarus/ideintf/propedits.pp
class function TCollectionPropertyEditor.ShowCollectionEditor(
ACollection: TCollection;
OwnerPersistent: TPersistent;
const PropName: String): TCustomForm;
begin
{ // proposed code removed
if CollectionForm = nil then
CollectionForm := TCollectionPropertyEditorForm.Create(Application);
CollectionForm.SetCollection(ACollection, OwnerPersistent, PropName);
CollectionForm.EnsureVisible;
} // end code removed
// proposed new code
if CollectionForm = nil then
begin
Application.CreateForm(TCollectionPropertyEditorForm, CollectionForm);
CollectionForm.FormStyle := fsStayOnTop;
end;
CollectionForm.SetCollection(ACollection, OwnerPersistent, PropName);
CollectionForm.Show;
// end new code
Result := CollectionForm;
end;
Note:
Please remember that the concept of fsStayOnTop is windows specific. fsStayOnTop
is very annoying under X, because it stays on top of everything.
Gladfully fsStayOnTop only works if BorderStyle=bsNone under X.
Mac OS X knows more window modes than windows and X together. Eventually we need
some TCustomForm properties to get the whole range of possibilities of all
platforms instead of only the few winapi modes.
Maybe this behavior should be configurable and the default should depend on the
platform.

Second problem. The files created with UTF8 now. Right. But if set
Encoding to CP1250 (after pressed Change file) File Settings/Encoding
displays good CP1250 value but if reopen the project the File
Settings/Encoding displays UTF-8 again.
Are there any CP1250 characters in the file?
The IDE does not save the information about the encoding. It only saves the text
in the encoding. If the file contains only ASCII characters, then setting CP1250
as encoding has no effect.
You can add {%encoding CP1250} as the first line.

No, because the source editor is only one part of the IDE, so a save must be handled one level higher saving is not as plain as one can expect yes the Ide will or should have some structure holding the combined data. Sometimes only parts are known. The glue class is TUnitInfo. It does not hold all data, but with it you get to everywhere else. But at current it appears it has to go down to code-tools and/or SynEdit (or SynEdit via code-tools) to get the actual Text. Correct. The actual file content is in the codetools. The actual lines as seen in the source editor is in synedit. The codehelp can hold the xml nodes. The form designer holds the lfm as component. ...

The codetools have that already. But for speed you have to optimize in one way or the other. You can not have both fast. This is not a proposal to throw over all the working code. This is first to see which directions make sense inside SynEdit, and maybe SourceEditor at some stage. Once that has developed into a more modular form, and gained the ability to provide that functionality, it can be reviewed, if any other code could benefit from it.

Re: [Lazarus] csvexporter
Zitat von Andrea Mauri andrea.mauri...@gmail.com:
Dear all,
when I put a csvexporter on a form lazarus automatically adds to my
project lazdbexport unit if I am under windows and fpccsvexport if I am
under Linux.
I didn't try cvsexporter myself.
Correct me if I'm wrong: When you drop a cvsexporter component onto a form, the
IDE adds a unit. And this unit is different on windows and linux?
If yes, then yes, you have to do the below.
So I have to do this:
{$IFDEF WINDOWS}
lazdbexport;
{$ENDIF}
{$IFDEF UNIX}
fpcsvexport;
{$ENDIF}
Is it ok?
... although IMO the package should be restructured, so that the IFDEFs go into
the package instead of to the using code.

Re: [Lazarus] Environment options corrupted
Zitat von Tom Verhoeff [EMAIL PROTECTED]: We use Lazarus in our first year programming education (as an experiment). There are various issues that we encounter, some small, some bigger. OS? FPC Version? Laz Version? Here is one that I don't understand. We have had a few instances where a window consistently failed to show up: * Object Inspector * Messages In both cases, it turned out that the saved options were to blame. In one case, I advised to remove all user-specific Lazarus configuration files (including environmentoptions.xml). Restarting Lazarus, will apparently recreate default option settings. The window then did show up. In another case, I looked a little further and noticed that the window position for the Messages window had a very large Top coordinate (as saved in environmentoptions.xml). So, it probably did open, but outside the visible screen region. I edited the options xml file, restarted Lazarus, and the window appeared again. As you can immagine these are quite annoying experiences (not only for the students, but also for teachers). Questions: * How can a student easily overcome this situation? Is there e.g. a way to sanitize saved options? Note that finding the relevant file is not trivial (so it is harder for me explain manual santization in a FAQ). * How can this happen in the first place? Either by closing the IDE on a big screen resolution and opening it on a small one. OR because of a bug in the widgetset returning the wrong window coords. * What can be done to avoid this in the future? I added some checks so that the IDE applies some bounds to the restored windows positions, so that at least a portion of the window should be visible. r17758. We can not auto move the whole window onto the screen, because some people need negative coords.

Do you mean: Environment / Options / Environment / Form Editor / Auto create forms when opening a unit ? No. When a GUI program is started in the IDE, the designed forms stay on the desktop and are overlaid when the windows are created by the application. Moving the runtime form reveals the designtime form, what's very confusing. I see. At the moment there are only two choices: nothing, and hide all IDE windows. You want to hide only the designer forms. Probably the OI and the anchor editor should be hidden in that case too. Either the checkbox should be replaced with a radiogroup or with a checkgroup. What do others think? Docking should be handled properly in design state (Windows). It's unclear whether it should be possible to dock forms at design time, or whether it should be disabled at all. It seems to me that at design time only the default dock manager can be used, so that docking at design time doesn't make much sense? No docking at design time. Then it should be properly disabled. As a workaround I leave the designed mode as dmManual, and turn it into dmAutomatic in FormCreate - but that's not a solution to the problem. Docking should *not* work for components with csDesignTime - that means the LCL should prohibit it. Can you give some more details how to reproduce this bug? What about the LazDoc programs?

Re: [Lazarus] Lazarus questions (auto complete, searching, docking, edit height)
Zitat von Marius [EMAIL PROTECTED]: After release fpc 2.2.2, recent TFrame introduction and some spare time i'm gonna experiment some more. Compiling went very well and i had some quick looks today with a few simple projects. I have collected a few simple questions: Please create one thread per topic. -Is there an ide option to turn off the auto complete option of the comboboxes in both the find dialogs. I keep searching for the wrong text because of it ;) Would it be a problem if i adjusted it with a switch via the editor options? Standard will be autocomplete=true. IMO it would be more intuive, if there is a speedbutton to the right of the combobox to turn it on/off. -What are the thought on having a combined Find and Find in files dialog? How about a form with the findtext and replacetext on top and a pagecontrol below with two tabs for the standard and find in files? They have different sizes. The find dialog is small and is positioned, so that the current line is still visible. This is not possible with the find in files dialog. -Is it possible to turn on docking via the ide options? no Or is it still done via an include file? (i forgot which include file it was though). Would it be a problem if i introduced a switch in the editor options for this or is this unwanted? I know its still beta, but still i like it.. When it is finished, you can dock and the IDE stores the state. So that on next start it will restore the docking layout automatically. An option to turn it on/off is not needed. Maybe some common layouts will be available (e.g. undock all, dock like Delphi 7 or something like that). -Why is the default height of an edit these days 23 instead of 21, has this changed recently? The edit(s) looks kind of large and weird having that height. Is there any reason for this particulary height or is this an issue in my lazarus instalation? Set Edit1.AutoSize=true to get the default height of the current platform. -Would it be a problem to have a seperate IDE window for the structure view instead of a fixed one in the object inspector. IMO the current structure view is to small and it is also limiting the size of the object explorer. At the moment you can only use the splitter between to change the size. -I still see the same keyboard bugs in the objectinspector. Which ones? What is the best (and quickest) way to apply patches into lazarus these day's? Quick for you, or quick for the lazarus devels? A change to the keys/focusing of the OI must be tested on all platforms.

Ok, but I do not quite understand the part of comment about 'end' keyword --
where can it be used as non-reserved?
As label in asm.
Also, the list was taken straight from the
FPR Reference guide, so if it is incorrect, then the guide should be fixed
too.
The list correct, that each listed word can be a keyword.
And yes, it is incorrect to not list the exceptions.
Regarding the non-reserved keywords (called 'modifiers' in the Reference)
I think it would be better to explicitly say the are not included, instead of
only offering one example ('static').
BTW, 'static' seems to be unknown to FPC 2.2.2 is it new in 2.3 series?
It's only available with the -St switch.

The second line would not compile. Button1.caption := 'Press again'; Button1.caption := ´Press again´; I would like to know where I can set the preferences of the editor to correct this.

I would like to throw up a suggestion for extending the editor's hinting
functionality.
We use Lazarus in a first-year introductory programming course.
One of the rules in our coding standard is that every variable
declaration needs to be accompanied by an explanatory comment.
It would be nice if the editor could show the comment associated with the
variable's declaration when you enter/point at an occurrence of that
variable.
This resembles the functionality where you get the routine prototype
when entering/pointing at a routine invocation.
Of course, this could apply to other names as well (constants, types,
routines). In fact, for routines, the prototype only shows you the
_syntactic_ specifics of that routine. _Semantic_ specifics are typically
addressed in a comment.
It might be necessary to use a special marker (cf. Javadoc) to
help the editor recognize such comments-to-be-used-for-hinting.
This functionality would further increase the value of adding comments
to definitions and declarations.
Implemented in svn 16843.
For example:
var
i: integer; // comment starting in same line
c: char;
{ long comment starting in next line}
Comments in front are not yet implemented.
By the way, I hired a student (Thorstin Crijns) to do some work on
improving Lazarus for educational use. This should benefit all Lazarus
users, both aspiring beginners and experienced users.
Great.
You'll be hearing more from Thorstin in the future.
I have asked him to start with the built-in help facility and
documentation. Other items on the list are the built-in debugger support,
and template support. Editor features could be another thing, but he
will need more help there.

Re: [Lazarus] Exception when I change betwen forms
Zitat von Reenen Laurie [EMAIL PROTECTED]:
You may need to post your application's .lpr as well... We don't know if the
forms are created in there or not.
I am not sure you can assign Appliction as the parent of a form... isn't
it just null or self? Smarter people will know that...
You confuse Parent and Owner.
TForm2.Create(Application) sets the Owner, not the Parent. Using Application as
Owner for forms is normal and allowed. As Parent it won't even compile, because
TApplication is not a TWinControl.
Owner = responsible for freeing component (can only be set at creation)
Parent = visual parent (can be changed at any time)
To debug an access violation, run the program in the debugger and create a
backtrace. The wiki explains how.
Mattias
ie.
Form2 := TForm2.Create (self);
or
Form2 := TForm2.Create (null);
In the .lpr file the command is different too...
Application.CreateForm (TForm2, Form2);

Sometimes in a simple applicattion whith a principal form and several
secondary forms accesed by a TMainMenu I get the error:
Access violation.
Press Ok to ignore and risk data corruption.
Press Cancel to kill the program.
when I branch between forms. Anybody help me?
My application:
unit Unit1;
{$mode objfpc}{$H+}
interface
uses
Classes, SysUtils, LResources, Forms, Controls, Graphics, Dialogs, Menus;
type
{ TForm1 }
TForm1 = class(TForm)
MainMenu1: TMainMenu;
MenuItem1: TMenuItem;
MenuItem2: TMenuItem;
MenuItem3: TMenuItem;
MenuItem4: TMenuItem;
procedure MenuItem1Click(Sender: TObject);
procedure MenuItem2Click(Sender: TObject);
procedure MenuItem3Click(Sender: TObject);
private
{ private declarations }
public
{ public declarations }
end;
var
Form1: TForm1;
implementation
uses Unit2, Unit3, Unit4;
{ TForm1 }
procedure TForm1.MenuItem1Click(Sender: TObject);
begin
Form2 := TForm2.Create (Application);
try
Form2.ShowModal;
finally
Form2.Free;
end;
end;
procedure TForm1.MenuItem2Click(Sender: TObject);
begin
Form3 := TForm3.Create (Application);
try
Form3.ShowModal;
finally
Form3.Free;
end;
end;
procedure TForm1.MenuItem3Click(Sender: TObject);
begin
Form4 := TForm4.Create (Application);
try
Form4.ShowModal;
finally
Form4.Free;
end;
end;
initialization
{$I unit1.lrs}
end.
Unit2.pas
unit Unit2;
{$mode objfpc}{$H+}
interface
uses
Classes, SysUtils, LResources, Forms, Controls, Graphics, Dialogs, Menus;
type
{ TForm2 }
TForm2 = class(TForm)
MainMenu1: TMainMenu;
MenuItem1: TMenuItem;
procedure MenuItem1Click(Sender: TObject);
private
{ private declarations }
public
{ public declarations }
end;
var
Form2: TForm2;
implementation
{ TForm2 }
procedure TForm2.MenuItem1Click(Sender: TObject);
begin
Close;
end;
initialization
{$I unit2.lrs}
end.

Re: [Lazarus] Event editing on ARM Linux
Zitat von Mark Morgan Lloyd [EMAIL PROTECTED]: 0.9.25 compiled for Linux on ARM (little-endian) appears to have a problem with the event editor. If I put a button on a form then double-click on the OnClick event I get a messagebox Unable to find method. Please fix the error shown in the message window. The message is Error: source not found: unit /usr/local/share/lazarus/lcl/units/arm-linux/stdctrls.ppu. I admit to being rather inexperienced on that particular platform but I think I've set it up the same as other systems. In particular I can specifically see lcl/stdctrls.pp. Irrespective of whether the problem has shown up it is impossible to exit without getting an access violation. Please test with svn r16827.

Re: [Lazarus] Lazarus addon - File Browser
Zitat von Graeme Geldenhuys [EMAIL PROTECTED]:
Hi,
I created a File Browser addon for Lazarus (thanks MvC for IDE
integration). See attached screenshot.
The last feature I need to add before I contribute the code, is drive
letter support under Windows. I know how to find those, as I have
done it before in fpGUI's File-Open Dialog.
My problem is, how am I supposed to implement platform specific code
in a Lazarus addon? Am I allowed to use IFDEFs?
eg;
{$IFDEF MSWINDOWS}
get available drive letters...
{$ELSE}
return / ...
{$ENDIF}
Yes.
[...]
* Dialog position persistence via IDE (Environment Options | Windows tab)
This is for windows only. For dialogs use:
uses IDEWindowIntf;
FormCreate
IDEDialogLayoutList.ApplyLayout(Self);
FormDestroy
IDEDialogLayoutList.SaveLayout(Self);
Make sure your dialog has a unique 'Name'.

Re: [Lazarus] Showmodal trouble
Zitat von Sebastian Kraft [EMAIL PROTECTED]: Hello, have some trouble with Form.ShowModal... Form1:= TForm1.create; Form1.ShowModal; Should bring Form1 to front, keep it on top of all other project forms and stay there until it is closed. Is this right? Yes. (Except other ShowModal forms.) But sometimes when I click on the Mainform behind Form1 Mainform comes to front and Form1 is hidden behind it I am using GTK2 widgetset from svn. Am I doing something wrong calling ShowModal? Or is it a bug? What window manager are you using? For example ubuntu with compiz has such a bug. This has nothing to do with the LCL or the gtk2, but compiz in general.

Re: [Lazarus] TMS component for lazarus released

I told the TMS people so: there is currently no workable solution. As soon as someone recompiles the LCL, it's broken. Even if the trial is released (without source, only .ppu and .o files) for a specific version of Lazarus and FPC? You still need to recompile lazarus. It's enough that 1 file of the LCL is recompiled. eg; Trial only works with latest stable released versions of FPC (2.2.0) and Lazarus (0.9.24) If you use any other versions of FPC or Lazarus, you can't use the trial component. Could this work? I doubt it, since you must recompile lazarus, and chances that it recompiles an LCL file are very close to 1... The IDE does not recompile the LCL when installing a package. That's why 'unit interfaces not found' is a FAQ. Mattias ___ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus
