Setting Font Color on certain controls

[Andrew Spencer 2]

Why can I set the Font.Color property, in Delphi 7, for controls like TCheckBox (and descendents TDBCheckBox etc) TRadioGroup and get the expected result. But in Delphi 10.4.2 everything remains clWindowText (or clBlack).

 

TLabel.Font.Color works, but most other controls do not.

 

Have I really just not noticed this for the past few years!?

If you use themes, don't be surprised.

If you enable Runtime Themes you delegate the drawing for some components to Windows and the colors from the Active Windows Theme is used. In ancient versions of Delphi this was done through XPManifest.

 

You can use VCL Styles to customize the drawing.

This is the style support at work. You can disable/override it on a control basis using the StyleElements property.

And also introduce large numbers of obscure bugs that will take forever to debug.

Or instead of dealing with the Vcl/Theme style you can easily put a label/panel next to a control and color it however you like and maybe add handler to simulate same behavior for mouse clicks. (Anchoring works great on that matter)
