Getting an event when dialog opens - maybe recieving wxEVT_INIT_DIALOG

[LonelySTar]

Hello together,

I want to write a plugin to replay user actions. For this I need to get informed when a dialog box opened and is ready for input. I believe that the wxWidgets event "wxEVT_INIT_DIALOG" would be exactly what I need.
But how can I recieve it? Connecting(with connect) to the main frame does not work .
Any Ideas on how to do it?

Thanks!
Nathan
