BN_UNPUSHED
The
BN_UNPUSHED notification message is sent when the push state of a button is set
to unpushed. The parent window of the button receives this notification message
through the WM_COMMAND message.
BN_PUSHED
BN_UNPUSHED
is the same as the BN_UNHILITE notification message.
This
notification message is provided for compatibility with applications written
for versions of Windows earlier than version 3.0. New applications should use
the BS_OWNERDRAW button style and the DRAWITEMSTRUCT structure for this
task.
