Version 7 of busy

Updated 2002-09-10 17:41:45

BLT has a busy command, which

  • changes the cursor to a "clock-face"
  • captures all pertinent WIMP events (so "clicks" don't back up ...), and
  • after the operation in question has finished, restores the cursor.

The way BLT manages the user interface is by pasting an invisible window over the "busied" frame. The invisible window intercepts all clicks and keystrokes ...


The effect of clock-face cursor can be had in pure Tk by

 . configure -cursor watch
 update
 # time-consuming action here...
 . config -cursor {} ;# RS

Example code for the cursor change appears in an old private page [L1 ] as well as the Cookbook [L2 ].
