[lazarus] fpgui font bug
While testing fpgui, I had a problem with default font, because Arial-10
wasn't found.
So I looked into the source. I fixed my problem changing the default to
Sans-10, but I spotted what it seems a bug to me.
In the following section of code form GFX_X11 lines 1281 on:
if not Assigned(FDefaultFont) then
begin
{$IFNDEF XftSupport}
FDefaultFont.FontData := XLoadQueryFont(Handle, 'fixed');
{$ENDIF}
..
if FDefaultFont is *not assigned*, attempting to write
FDefaultFont.FontData doesn't appear right.
I'm not familiar enough with X11fonts witchcraft to attempt to fix it.

Re: [lazarus] fpgui font bug
Are you using Xft font support (the default) or standard X11 font support?

I made a change to this code in revision 85 of fpGUI. Thanks for
spotting the problem.

It's the philosophy of Open Source, isnt'it?
My compliments for your work. If I could manage to squeeze some time out
of my engagements I'd gladly contribute more effectively.

[lazarus] After compiling and debugging my app, sometimes (randomly) a failure pops up.
Dear devvers, I am trying to write quite a nice application in Lazarus. Now sometimes when I compile my project and run it (debug via Lazarus) i get the following error: (slightly different probably, translated from Dutch) Running is temporarly halted. Address: $7C810665, Procedure: KERNEL32!CreateThread, File (doesn't report a filename.) After clicking OK, debugging goes on immediately. I have no clue where this possibly comes from. My setup: Windows XP Pro SP2, Lazarus 0.9.22, fpc 2.0.4 How to debug this irritating thingie?

[lazarus] listview example cannot be loaded in the IDE on win64
Hi, I am trying to find out why the listview example doesn't load in the IDE on windows 64. I enabled and added some debugln's and got this information. The listview has an empty [TJITComponentList.ReaderError] Error reading ImageList1.Bitmap: Access violation ignoring=0 Some more writelns told me the crash occurs when FOnChange(Self) is called in procedure TCustomImageList.Change; The value of TMethod(FOnChange).code points to a copy of the TPersistentWithTemplates.DoNothing procedure which is located on the heap. It is a place holder for procedure TForm1.ImageList1Change. Questions: * Is this code actually to be executed? Was it designed so that the IDE could execute this code at design time? I think the answer is yes. * I tested on windows XP 64. Does anybody know if the 64 bits version of windows works differently in this respect than the 32 bits version? For example does it proctect the memory on the heap from execution?

If it is off, then there is no locking and any thread may run at any time. If on, then only the current thread may run when the inferior is resumed. The step mode optimizes for single-stepping. It stops other threads from seizing the prompt by preempting the current thread while you are stepping. Other threads will only rarely (or never) get a chance to run when you step. They are more likely to run when you `next' over a function call, and they are completely free to run when you use commands like `continue', `until', or `finish'. However, unless another thread hits a breakpoint during its timeslice, they will never steal the GDB prompt away from the thread that you are debugging. show scheduler-locking Display the current scheduler locking mode. _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

I think the answer is yes. Short answer: yes Long answer: It is the really dirty hack in the IDE. It was done, because assigning a 'real' TMethod to an event has the advantage that all OI, RTTI and all streaming code work without hacks or additions. * I tested on windows XP 64. Does anybody know if the 64 bits version of windows works differently in this respect than the 32 bits version? For example does it proctect the memory on the heap from execution? If yes, then it is finally time to use the Delphi half Assigned trick and to check and extend the whole OI, RTTI and Streaming code to support this.

[lazarus] Run Error 216
I am getting the following error as I exit one procedure and enter another. I believe it has something to do with allocating memory using the SetLength procedure for a dynamic array. That is the line it appears to be failing on. External: SIGSEGV Address $0806360B SYSTEM_SYSGETMEM_VAR$LONGINT$$POINTER This is then followed by a RunError (216); I am not sure the dynamic array I am allocating in the first procedure is really getting deallocated when the procedure ends even though I am setting it's length to zero before the procedure ends. The array is declared locally so once the procedure end, that memory should be returned to the free store. Has anyone see this before?

Re: [lazarus] devel: TRawImage questions
On Mon, 16 Apr 2007 00:40:08 +0200 Marc Weustink [EMAIL PROTECTED] wrote: Hi, I'm currently reworking/verifying TLazIntfImage/TRawImage and ran into sume questions. Since the devel list is down. I'll ask it here. 1)What is the purpose of CreateBitmapFromRawImage ? When looking at the win32 implementation it looks like this function should create a bitmap compatible with the current display. But I wonder if this meant this way (you don't want to create a compatible bitmap in all cases) The idea is to create a bitmap compatible with the TRawImageDescription. If it should be compatible with the current display, then it must be filled with compatible values. If the values are not compatible, then the lcl intf can either create a non bitmap, which is incompatible to the display (DIB?), or fail. 2) Why are the DataSize and MaskDataSize (which I rather would like to call AlphaDataSize) Yes, that would be better. It is a pitty we can not rename the Mask in TBitmap. defined as PtrUInt. What is the purpose of this ? A definition like this means that code on a 64bit platform can handle larger images ? Yes. IMO, we should keep this cikd of structs constant, so either define the size as DWord or as QWord. Why? TRawImageDescription is for handling memory images, not for streaming.
