It wasn't implemented =) This is what I was looking for, thanks.
I did a quick and dirty implementation for DrawText windows API and
TLabel now works =) (no font, size, etc implemented however)
Here is my code:
function TQtWidgetSet.DrawText(DC: HDC; Str: PChar; Count: Integer;
var Rect: TRect; Flags: Cardinal): Integer;
var
WideStr: WideString;
begin
Result := 30;
WideStr := WideString(Str);
if DC = 0 then Exit;
TQtDeviceContext(DC).drawText(Rect.Left, Rect.Top, @WideStr);
end;
The problem is that the Qt function drawText doesn't return
information about the size drawn, so I just hardcoded to 30 until a
better solution arrives.
Another problem, it works, but I think that LCL tryes to paint outside
the paint event, I receive some messages like this:
QPainter::begin: Widget painting can only begin as a result of a paintEvent
I think I will do like Den Jean sugested and use that Qt function to
check if I'm on a paint event.
thanks,
