SystemClick

Process mouseDown occurring in a system window

#include <Desk.h> Desk Manager

void SystemClick( theEvent, theWindow );

EventRecord *theEvent ; as used in previous GetNextEvent

WindowPtr theWindow ; as obtained via FindWindow

Call SystemClick to take control when the mouse is clicked in a system

window (i.e., a DA window).

theEvent is the address of a 16-byte EventRecord structure; it normally

contains the data obtained from a recent call to GetNextEvent.

theWindow identifies the window in which the mouseDown occurred. It is

normally the value obtained from a call to FindWindow that yielded

a return code of inSysWindow.

Notes: SystemClick takes control and process all events associated with a click

in a non-application window; e.g., events meant to be seen by DAs.

A typical usage might look like:

WindowPtr whichWindow;

if(WaitNextEvent(everyEvent, & theEvent, 0, nil)) {

if ( theEvent.what == mouseDown ) {

switch ( FindWindow( theEvent.where, & whichWindow ) ) {

/* check for mouseDown events in other areas */

case inSysWindow:

SystemClick( & theEvent, whichWindow );

break;

case inContent:

/*... etc ... */

}
