Online people ask: button on the toolbar this method can not be used

People on the Internet answered:

You can put the button in the Gtkeventbox, and then put the Eventbox into toolbar, so that Eventbox motion-notify-event can be processed.

Mouse move-in and move-out handler functions
Static Gboolean Banner_image_motion_notify_handler (gtkwidget *widget,gdkeventmotion *event,gpointer data)
{
Mouse Move in
if (Event->type = = gdk_enter_notify) {//Enter the thumbnail, you will cancel the autohide temporary thread
Banner_cancel_autohide ();
Mouse out control
} else if (Event->type = = gdk_leave_notify) {//need to re-open autohide thread
Banner_autohide_tip_window ();
}

Return false;//no need to process anymore.
}
