Summary0019384: TCanvas.Brush.Color problem on GTK2
DescriptionHi guys.

I already discussed this problem with Bart on the forum:
http://lazarus.freepascal.org/index.php/topic,13167.msg68590.html#msg68590 [^]

And we made a conclusion there seems to be without any problem with TMaskEdit component itself.

I guess there must be an issue with root permission:
http://lazarus.freepascal.org/index.php/topic,13167.msg68649.html#msg68649 [^]

In addition, no one gives me any suggestion with TCanvas.Brush problem yet :(

Thanks.
Additional InformationUbuntu 11.04 with Unity and GTK2 2.24.0
Korean Language pack installed.
Tested under FPC 2.4.2 + Lazarus 0.9.30 from Synaptic and trunk version via SVN.
TagsNo tags attached.
Fixed in Revision36929

 The first issue is duplicated by this: http://bugs.freepascal.org/view.php?id=19413 [^]

But still the second one remained.

 You reported the bug in the wrong project (Mantis support)...

 Quoted gitspielen from the forum:


=============================================
[quote]
secondly i wrote some texts on timage.canvas setting its brush.color for their background colors like this:

Code:
with Image1.Canvas do
begin
  Font.Color:=clRed;
  Brush.Color:=clYellow;
  Brush.Style:=bsSolid;
  TextOut(5, 5, 'blah blah');
end;

red texts on yellow displayed on windows box as i expected but only the text color changed on linux. what's wrong with that?

=============================================

I have adjusted the topic title to reflect the problem.

 @Zeljan: You should ask gitspielen.
I merely tried to clarify what this bugreport is about (the actual description was rather vague), citing his posting on the forum.

 @gitspielen: please provide a sample program (sources only) demonstrating the issue.

 hm...qt works fine, but indeed gtk2 does not change brush bg in this case.

 I confirm that this is bug on gtk2.

 This is *workaround* atm (only for gtk2):
with Image1.Canvas do
begin
  Font.Color:=clRed;
  Brush.Color:=clYellow;
  // Brush.Style:=bsSolid; NOT NEEDED FOR TRUNK, bsSolid is already setted up
  // when Color is changed
  FillRect(3, 3, TextWidth('blah blah') + 2,TextHeight('blah') + 2);
  TextOut(5, 5, 'blah blah');
end;

 actually gtk2 does not respect brush state + color when drawing text.

 Please test and close if ok.
