Abstract
The present invention provides the capability to use customized procedures to manipulate and control objects in graphic implementations. It provides externalizes much of the underlying object manipulation functionality. A customized procedure is executed at various 'trigger' points including: the expiration of a specified period of time; the opening or closing of a window; or, when input from a mouse input device is received. There are several different types of mouse events: mouse button down; mouse move with button down; mouse move with no button down; and mouse button up. A graphic object associated with a customized procedure that is triggered by a mouse event is called a 'button object.' The customized procedure associated with a button object has four parameters: buttonobj, hitobj, win, and eventinfo. The buttonobj parameter refers to the graphic object having a button procedure that is currently being executed. The hitobj parameter refers to the graphic object that was selected triggering the mouse event. The present invention provides a tree-like organization for grouping its graphic objects. If the selected object does not have an associated button procedure, the tree-like structure is traversed upward to find an object that does have an associated button procedure. The win parameter identifies the window that the mouse event occurred in. The eventinfo parameter points to a record containing information pertaining to the mouse event that triggered the procedure execution. A customized procedure driven by a mouse event transforms a graphic object into a 'button' object.
