Re: [Lazarus] ColotToRGB in GTK apps
Hello, I found solution: in unit GtkProc is procedure UpdateSysColorMap that updates SysColorMap array (from where ColorToRGB gets RGB values of system colors), but functionality of this procedure is disabled (NewSysColors is not defined). So i writed own procedure that based on code of mentioned procedure. Now this procedure I call in OnCreate and then ColorToRGB returns correct values. -- Valdas Jankūnas ___ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus
[Lazarus] TStringGrid, One click, multiple events.
Hi,
I'm sure this has been covered often, but none of my searches seems to find it.
I have a routine to remove a row from a TStringGrid if the user selects it.
The problem is that the onSelection event seems to be trigered twice:
procedure TForm1.StringGrid1Selection(Sender: TObject; aCol, aRow: Integer);
var i:integer;
begin
if messageDlg('Remove
'+StringGrid1.Cells[aCol,aRow]+'?',mtInformation,[mbYes,mbNo],0)=mrYes
then
begin
for i:=arow to StringGrid1.RowCount-2 do
begin
StringGrid1.Cells[0,i]:=StringGrid1.Cells[0,i+1];
StringGrid1.Cells[1,i]:=StringGrid1.Cells[1,i+1];
end;
StringGrid1.RowCount:=StringGrid1.RowCount-1;
end;
end;
The user will click the item to be removed, the dialog will appear
asking for confirmation to delete the row, but on clicking yes, while
the row is deleted as expected, the dialog pops up again, asking the
user if the next line should be deleted.

Re: [Lazarus] unable to rebuild lazarus
Mattais, I deleted the exe file, then selected Run. The project recompiled successfully, but now it says (debugging...) and is not doing anything else. bob k. -- From: Mattias Gaertner [EMAIL PROTECTED] Sent: Saturday, July 26, 2008 1:46 PM To: lazarus@lazarus.freepascal.org Subject: Re: [Lazarus] unable to rebuild lazarus On Sat, 26 Jul 2008 13:21:55 -0400 Bob K.

You misunderstood me. To find the error 'unit interfaces not found' you should compile with -vt -vu. The can not create object files means for example: disk full, no write permissions, output directory does not exist or output file is locked. Delete the old exe before compiling.

This patch does the following: - Avoid the creation of WidgetInfo to combox childs [gtk1] - Pass WidgetInfo as the data to the changed event handler [gtk1] - Update the ItemIndex cache when inserting items [gtk2] Thanks. Applied. BTW: the file gtkobject.inc seems unused. Initially i got confused after searching for the places where the info is freed. gtkobject.inc? AFAIR it was removed 9 months ago.

I enabled it by default. This fixes the 'random' colors. But remember that the rest of my mail still holds true: These values depend on theme and not every theme defines all values. So don't expect that your program will work on every machine. Mattias ___ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus
