demoWaitForInput

A function that can be used in Scripting.

Syntax and semantics

demoWaitForInput ( ): wait for a user event (click or key press) in the Demo window.

This function blocks until the user clicks in the Demo window or types a key into the Demo window.

Once the function finally returns, it returns the value 1 (true). This makes it possible to use this function in a while loop:

   while demoWaitForInput ()

       if demoClicked ())

           # handle the mouse click

       elsif demoKeyPressed ())

           # handle the key press

       endif

   endwhile
