How to change the color of TButton?

Question

In "Borland" C++ Builder 6, how to change color of button (TButton)?

I've tried in this way

button->Font->Color = clRed;

but it doesn't work.

Answer 1

TButton is a thin wrapper around a standard Win32 BUTTON control, which gets its coloring from the OS, not the VCL. You cannot set the Color for a standard TButton. The Color property exists only because it is inherited from a base class.

That being said, the Win32 BUTTON does support a BS_OWNERDRAW style. You can use SetWindowLong() to enable it, then subclass the button to handle the WM_DRAWITEM message so you can paint the button however you want.

Here is an example component that derives from TButton and implements BS_OWNERDRAW to expose working color properties: TColorButton
