mouse(_down)   function



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 mouse <event>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.
