MEL: Progress Window

Ever wanted to build a progress window into a script you're running that is taking a long time? MEL has one built in already, and it works quite well!

int $amount = 0;

progressWindow
    -title "Doing Nothing"
    -progress $amount
    -status "Sleeping: 0%"
    -isInterruptable true;

while (true) {

    // Check if the dialog has been cancelled
    if ( `progressWindow -query -isCancelled` ) break;

    // Check if end condition has been reached
    if ( `progressWindow -query -progress` >= 100 ) break;

    $amount += 5;

    progressWindow -edit
        -progress $amount
        -status ("Sleeping: "+$amount+"%");

    pause -seconds 1;
}

progressWindow -endProgress;

You can find it in the MEL help file. It's fun.
