MOUSE(_down)

Syntax

buttonStatus = MOUSE(_down)

Description

If your program does not do any kind of event-trapping using the HANDLEEVENTS statement, then you can use the MOUSE(_down) function to determine whether the mouse button is currently down. In these circumstances, MOUSE(_down) returns _zTrue is the button is down, or _false otherwise.

The MOUSE(_down) function will not work if your program traps events using HANDLEEVENTS. Since most well-designed programs trap events this way, the MOUSE(_down) function is probably of limited usefulness. See the <a href="mouse%20event.html">MOUSE <event></a> functions to learn how to respond to mouse clicks using event trapping.

Note: You can also use the Toolbox function FN BUTTON to determine whether the mouse is currently down. FN BUTTON works regardless of whether your program uses event trapping.
