Hello,
I am trying to implement TLabel for the Qt widgetset. I implemented
ExtTextOut winapi function and then droped a TLabel on a form and
compiled it, but at run-time I get this error:
TControl.DoSetBounds Label1:TLabel Old=174,44,65,17
New=174,44,145497925,1208546853
ERROR in LCL: TControl.DoSetBounds Label1:TLabel Invalid bounds
Creating gdb catchable error:
[FORMS.PP] ExceptionOccurred
Sender=EInvalidOp
Exception=Invalid floating point operation
Stack trace:
$080AC6F8 RAISEGDBEXCEPTION, line 737 of lclproc.pas
$080DA7B3 BOUNDSOUTOFBOUNDS, line 440 of ./include/control.inc
$080DA545 TCONTROL__DOSETBOUNDS, line 445 of ./include/control.inc
$080DA1D1 TCONTROL__CHANGEBOUNDS, line 364 of ./include/control.inc
......
This doesn't happen with other controls I tested. Any ideas what this
is? Wrong values are being passed to DoSetBounds, but where does LCL
read the Width and Height of the control?
Another problem is that Qt does not allow painting outside a paint
event, but winapi is allows it. Has anyone had this problem before? Like
on Carbon widgetset, perhaps.
Maybe I should try to detect if a drawing function was called outside a
paint event and if so, create a list of functions to be called when a
paint event occur.
Or Should I send a paint message everytime a paint function is called
outside OnPaint?
Any other ideas?
thanks,
Felipe
