How to make a dialog 'fail to open'?

[Jurko Gospodnetić]

   Hi.

   I was wandering how to allow my dialog to 'fail to open'. It contains 
some code in its wxInitDialogEvent handler that could fail, in which 
case I do want to report an error and not allow the dialog to be open.

   The only way I found to do this so far is to throw an exception. Is 
this 'the only way' since wxWidgets attempts not to require exceptions?

   I tried skipping the event but could not find a way to skip the 
default event handler as well. As I saw from the code - if I could do 
that then the dialog would fail to open.

   Also... have not found any documentation on this...

   Using wxWidgets 2.8.3 on Windows XP. MSW build.

   Best regards,
