To be able to interact with the interface the application must return the
control to the system even if for just a moment. The IupLoopStep function
does exactly that.
So if you have a long processing, you can call IupLoopStep periodically
so the system can process pending messages, including drawing controls,
clicking on buttons, etc. Of course that creates other problems, you must
disable things in the interface that must not be activated during the long
process.
One common approach is to use a progress dialog to display processing
progress information. IupProgressDlg can be used along with IupShow. The
main dialog can then be disabled with SIMULATEMODAL=Yes.
