WaitCursor true|false
Description
Set WaitCursor to true to display a wait cursor. The design of the cursor depends on the browser. Set it to false to turn the waitcursor off again. This command does not do anything on mobile devices, since they do not have a cursor.
Example (Basic)
Rem WaitCursor Example WaitCursor True Sleep 5000 WaitCursor False
Example (JavaScript)
// Cursor Example with Delay sleep=function(ms) { //used for delay to avoid loop that uses up CPU var caller = sleep.caller; if (caller.sleepTimer) { delete caller.sleepTimer; return true; } caller.sleepTimer = window.setTimeout (function () { caller.apply ([]); },ms); return false; } delayPostProcessing=function(ms) { /* if you need a delayed response, put all post processing in this function * anything outside this function will execute prior to the delay even if it * comes after calling this function */ document.body.style.cursor = 'wait'; //busy style cursor during delay NSB.Print("Cursor changed to busy"); if (!sleep (ms)) return; document.body.style.cursor = ''; //normal cursor NSB.Print("Cursor restored to normal"); NSB.Print("Continue processing inside the wrapper after delay"); NSB.Print("... and continue processing inside the wrapper"); } preProcessing=function() { //do your pre-processing before delay here var delayMS=5000; NSB.Print("After processing this line, cause delay of " + (delayMS/1000).toString() + " seconds"); delayPostProcessing(delayMS); //force delay now NSB.Print("This line ignores the delay"); } preProcessing(); //this runs all code prior to the delay NSB.Print("This line ignores the delay also");
