TButtons and “runtime themes”: peculiar behavior

Question

Have you seen this?

I have a little utility application (for easy load / test xml generation from CDS and/or DBGo), and I had put some buttons (the poorest button of all, TButton) to trigger some actions.

I never paid attention to appearance, because I'm the only one that uses it. So today I added a new button, and they appeared different from the others in designer - but not when running. It's just an copy and paste process (change the button name, caption and event - the rest is equal to the origin).

When I looked the other buttons have an grey gradient and round corners, the button I copied and pasted not (just a bare rectangle). When running all buttons where just bare rectangles.

So I discovered that on designer, W7 and delphi are applying themes. On running, they are obeying the Project/Options/Application/Enable runtime themes flag.

This is annoying. There's a way to make Delphi doing that obeying the project options flag on forms designer? (Or even manually if is not possible to automate that)?

EDIT:

The toolbars on the form are from CNWizards ;-)

EDIT II:

Apart of disabling themes for the IDE executable, all buttons get themed equally if the form (or project) is reloaded. But it's really weird.

Answer 1

If you want to enable/disable themes in the IDE, then open the properties of bds.exe, select the 'Compatibility' tab, and make sure that the 'Disable visual themes' checkbox is unchecked/checked.

Programs that you run from the IDE will inherit the compatibility settings of the IDE.

Answer 2

Delphi IDE itself is an application and the way the designer draw the form is using the setting for the IDE application (delphi32.exe or bds.exe's compatibility settings) so the answer is no. The default behaviour is different between IDE versions, for eg. the opposite behaviour (not drawing themed) happened in past.
