new bordericon on forms

[Andre Jacobs]

Hi, I have this problem that I want to add a bordericon on a form like the
Help icon. So obviously I have to derive something from the tcustomform but
not having ever changed the look of a vcl I dont know how!

I also see that there is a bordericon set in forms.pas but it is not
possible to override that is it? I dont want to change forms.pas unless I
absolutely have to.

please help this desperate man, and just point me in the right direction.

Thanks!
Andre

The caption bar icons are drawn and maintained by Windows. The VCL has
nothing to do with their apearance, so overriding TCustomForm won't
help you. The BorderIcons property allows you to select which of the
standard buttons are displayed.

To place additional buttons on the caption, you have to handle
non-client messages, such as WM_NCPAINT and WM_NCLBUTTONDOWN, which
are sent when a window needs its non-client area (such as the caption
bar and borders) repainted, and when the user clicks that area.

You can download TCaptionControl from my page (see signature), which
allows you to place custom buttons on the caption bar. Full source is
provided, so you can modify the code to your needs.

You dont need to derive from TCustomForm (unless you want to add properties
or methods etc) to get another icon on the caption.

In order for you to get another icon up there, you would need to override
the WM_NCPAINT message and actually paint the icon yourself. Thats the only
way to do it.

I think there are some components available which do it, you can check up
one of the Delphi sites for it. Those components would also be trapping the
WM_NCPAINT message of the form, inorder to paint it.

Give our oxForm component a try. You can download it from our web site along
with many other components.
