MCClick

Your application should call the MCClick function when the user clicks in a movie controller window.

pascal ComponentResult MCClick (MovieController mc, WindowPtr w,
                                 Point where, long when, 
                                 long modifiers);

mc

Specifies the movie controller for the operation. You obtain this identifier from the Component Manager's OpenComponent or OpenDefaultComponent function, or from the NewMovieController function (described on page 2-28).

w

Specifies the window in which the event has occurred.

where

Indicates the location of the click. This value is expressed in the local coordinates of the window specified by the w parameter. Your application must convert this value from the global coordinates returned in the event structure.

when

Indicates when the user pressed the mouse button. You obtain this value from the event structure.

modifiers

Specifies modifier flags for the event. You obtain this value from the event structure.

DESCRIPTION

The MCClick function returns a value indicating whether it handled the event. The function sets the returned value to 1 if it handles the event. The function sets the returned value to 0 if it does not handle the event. In this case, your application is responsible for the event.
