Re: expose event following button press/release event

[Tony Wang <wangtao adi gmail com>]

Yes, I handled the two button events myself, and both return true.

There are not anything related with GtkWidgets in my app, I directly use cairo to draw my UI elements, and gtk+ is just used to handle the event.

handle the button press & release events yourself, and return true
from your handlers, thus preventing the default handler from running.
it sounds as if you don't want a GtkButton anyway, but something more
like a GtkEventBox that simply receives button events without
redrawing itself to indicate state to the user.
