Title: lazarus apps in rh9 don't run

Entered by: Pascal de Bruijn

Original Description:
I've retested the new 8.5.2 release, and still me applications won't run. Though lazarus itself does run fine.

Works for me

Title: TPaintBox drawing wrong origin

Entered by: domin

Original Description:
When I put TPaintBox on the form and do some drawing on it, It's always done from the origin (0,0) of the *Form*, not the PaintBox, which has left and top properties other than 0 (also on the runtime - I've checked it)

Updated by: Mattias

Status: Fixed

Comments:
The Get/SetPixel functions didn't consider the DCOffset. That's Fixed. If you find some other drawing functions with thsi bug, please tell.

I saw an anouncments, which says that TControl.Font property is readonly. I tried the source, and... It is really ReadOnly. So, I can't change Font property not only for TLabel (which normally should work for Delphi clones, but didn't work properly) , but for any other controls, including TStaticText (which worked). Moreover, TListBox.Items and TMemo.Lines can't be edited too. Why is it done? It worked OK, but was disabled.

Title: TImage.Picture.Bitmap.Canvas.Pixels

Entered by: domin

Original Description:
Any attempt to write to the pixels[x,y] array property generates division_by_0, while LineTo etc works very well.

Updated by: Mattias

Status: Fixed

Comments:
Set/GetPixel now consider the DCOffset. So they draw now to the right position. As for TImage.Picture: Most parts are not implemented.

Title: loss of gtk theme

Entered by: Pascal de Bruijn

Original Description:

When compressing (with upx.sf.net) an executable generated by lazarus, the project loses it's theme and then uses the gtk default theme.

This might just be a bug in upx. I don't know, that why i'm asking your opinion.

Updated by: Mattias

Status: Not a bug

Comments:
The lazarus gtk-interface loads the gtkrc file ParamStr(0)+'.gtkrc'. UPX decompresses the executable to /tmp/xxxx and runs the file there, so the original command is lost and the right gtkrc file can not be found.

MG

My fault. Sorry. Fixed.

Mattias

Sorry. Forget my nonsense. I didn't saw the

> procedure TForm1.Button1Click(Sender: TObject);

You are right. This does not work. This is not yet implemented. Please use always 'Invalidate' and draw in the 'OnPaint' event. It will make your applications smoother. This has nothing to do with LCL, this is true for all event based GUIs. Especially if you use the very slow Get/SetPixel functions.

Still works for me. Blue square in the paintbox.

// And I can see funny little blue square begining at (10,10) of the _Form_// BTW I'll try to download CVS again

TCanvas in cancas.inc uses the Get/SetPixel functions of the gtk-interface. Can you send me an example, where it does not work?

New Project, one button, one TPaintBox (left,top0) + simple code:

procedure TForm1.Button1Click(Sender: TObject);
var i,j: integer;
begin
  for i := 10 to 20 do
    for j := 10 to 20 do
       PaintBox1.Canvas.Pixels[i, j] := clBlue;
end;

This was one of those bugs, where you find some code, that exists and worked for years and now you wonder how the code did that.

Title: Changing MaxValue disables Spinedit handles

Entered by: Tom Lisjac

Original Description:

Spinedit works fine if one is dropped on a blank form and the program is immediately run. If the spinedit MaxValue is changed in the property editor, the spin handles are disabled when the program is run again. Saving the form and reloading shows 3.6757817268371582 in MaxValue... so something with stored properties appears to be broken in this control.

Floats were not implemented in fpc 1.0.7. This has been fixed in 1.0.8.
