Creating an OS close button? (WinAPI)

Question

I want to create a button that is basically Windows' close button. How could I do this? I want to avoid drawing this myself because I want it to look like that version of Windows' close button. Firefox's tabs do something like this. Thanks

Answer 1

The close buttons on the tabs in Firefox are part of its theme.

If you look in Program Files\Mozilla Firefox\chrome\ there's a zip file called classic.jar.

Inside this zip file is a png file skin\classic\global\icons\close.png.

This png file has the icons for the various states of the close buttons on the tabs:

from hg.mozilla.org

Answer 2

You can get at Windows XP+ theme specific UI elements via the DrawThemeBackground API.
Use WP_CLOSEBUTTON for the window X button (and one of CBS_NORMAL/HOT/PUSHED/DISABLED for its state) and you can draw one wherever you like.
