JMFrameMouseOver

Passes a mouse-over event to a frame.

OSStatus JMFrameMouseOver (
                     JMFrameRef frame, 
                     Point localPos, 
                     short modifiers);

frame

The frame containing the mouse. This should be the active frame.

localPos

The position of the mouse in frame coordinates.

modifiers

Any keyboard modifiers from the EventRecord structure. See Inside Macintosh: Macintosh Toolbox Essentials, for more information about the EventRecord data structure.

function result

A result code; see "JManager Result Codes".

DISCUSSION

To monitor the position of the mouse, you should call the JMFrameMouseOver and JMIdle functions each time through the event loop. Note that the client application must keep track of the currently active frame.
