I am using the Graphics32 TColorPickerGTK component, unfortunately, it doesn't support VCL Styles. My first thought was to clear the FBuffer in the PaintColorPicker() method as such,
FBuffer.Clear( Color32( StyleServices.GetStyleColor( scWindow ) ) );
works great for non textured styles, but, for styles like Glossy or Jet, not much chop.
An epiphany and I was on my way, copy the bitmap under the control with the Create() method and just paint it back on the PaintColorPicker () method.
ABitmap := TBitmap32.Create();
ABitmap.SetSize( Width, Height );
ARect1 := Rect( 0, 0, Width, Height );
ABitmap.Canvas.CopyRect( ARect1, {No canvas object}, ARect1 );
How do I get access to the underlying canvas of the form, so CopyRect works?
