nonVCL Style ändern

[Luckie]

also, wenn du eine Dialog Ressource hast, dann guck dir mal WM_CTLCOLORDLG an. Bei einem Button ist es nicht so einfach, den musst du komplett selber zeichen, also subclassen. Es gibt zwar die Nachricht WM_CTLCOLORBTN, aber

Zitat:

By default, the DefWindowProc function selects the default system colors for the button. Buttons with the BS_PUSHBUTTON, BS_DEFPUSHBUTTON, or BS_PUSHLIKE styles do not use the returned brush. Buttons with these styles are always drawn with the default system colors. Drawing push buttons requires several different brushes-face, highlight and shadow-but the WM_CTLCOLORBTN message allows only one brush to be returned. To provide a custom appearance for push buttons, use an owner-drawn button.
