File: popup.c Project: jihnsius/d2r

// Use: Left button (button 0) goes down, then up, then this is called
// as opposed to straight after the button goes down, holding down
// until an option is chosen.
// This is like the 'modern' behaviour of popup menus and also happens
// to be easier to implement because of the button code.
// Recommended for use in conjunction with a button gadget,
// i.e. when that button is pressed, call PopupMenu,
// update the button's text then the value in question.
