Example
This example demonstrates how you can use the 
option of user interface functions to allow user interface updates to be visible when performing a long Mathematica calculation by threading the calculation and ensuring that user interface update requests occur on the event dispatching thread.
Additionally, once a process is threaded, it allows the user to abort a long Mathematica calculation from the same user interface. This is accomplished by triggering an abort using 
, which does not require a kernel script evaluation to interrupt an existing kernel evaluation.
Another important feature of properly interrupting a calculation is proper placement of 
calls to allow interruption at certain points of the 
block, and to make sure that the rest of the 
will continue as expected. All 
blocks are automatically wrapped with 
by the GUIKit framework so that, by default, all scripts will evaluate without interruption. You should add 
blocks in scripts that perform longer calculations.
