RE: Catching key press events while model wx.MessageDialog(...) is shown?

Wouldn't a wx.ProgressDialog or a wx.agw.pyprogress be more appropriate than a modal wx.MessageDialog? You can optionally have an abort button (in addition to the "Stop" and check the returned values when you update it. AFAIK when a progress dialog is shown any active keyboard shortcut bindings should work & you can always disable other controls to have much the same effect as a modal dialog.

Subject: [wxPython-users] Catching key press events while model wx.MessageDialog(...) is shown?

I have a program that runs a long task in a background thread, and shows a modal wx.MessageDialog(...) in the foreground with a "Stop" button to stop the background thread. The long task is a sequence of work cycles, and the "Stop" button stops the sequence after completing the currently running cycle. So far, all is good (as in the attached example code).

I would like to add a mechanism that allows stopping the background thread immediately (without waiting to complete the current cycle) by pressing a key or key combination on the keyboard. For example, pressing the 'K' key on the keyboard should trigger a call to worker_thread.kill() in the attached example code. What would be a good appraoch to make this work? Is there a way to hook into the event loop of the wx.MessageDialog(...) to check for key press events? Of is there another way to check for key presses?
