Hello,
Is there any easy way to obtain the color of a component taking into
considerating all the factors? aka, propagating ParentColor, resolving
clDefault, etc.
I have my TCDPageControl on top of a form, but for
TCDPageControl.Color I get just clDefault, which turns out to be
black. =( using Parent.GetDefaultColor(dcBrush) also returned black in
Windows...
If there is no easy way maybe we should add one?
I think it is possible since clDefault is TColor($20000000) and clBlack
is TColor($000000) there are situations where the most significant bits
of clDefault are lost and the two colours become identical.
I've found that the Object Inspector's default component editor for
colours seems at times to initialise colours to $000000 whatever the
component's constructor may have directed.
In these situations I've resorted to overriding the Loaded method to set
the desired value.
