Hello, Lazarus mailing list.
I want to inform you that starting with r28344 all controls default
fonts an brushes will have clDefault color instead of clBtnFace/clWindow
as you had for years.
That was made because non windows widgetsets does not use clBtnFace
color for forms, clWindow for edit controls and also have different
ideas regards default font colors
I believe that I can't foresee all the situations where your code
depends on this. So I expect you will see some graphic glitches but hope
not much. Please report them as unswer to this message and to the bug
TCanvas mostly know how to handle clDefault color in different
situations but not in all.
TControl.Color := clDefault - is ok - control knows how to handle it.
TControlCanvas.Brush.Color := clDefault - is ok too because
TControlCanvas has TControl and get retrieve the correct representation
But TBitmap.Canvas.Brush.Color := clDefault will result in black color
because TBitmap knows nothing about control and can't resolve clDefault
to another color.
To obtain what clDefault color means for TControl use
