I'm isolating my problem with mapper. When i setup a mapper, the ESC key reverts changes in the edited widgets. That's ok, but i need to trap that situation. I need to do more than revert changes when i press ESC. For instance, before going into editing mode i disable some buttons. When i press ESC, i'm not in editing mode anymore, so i need to enable that buttons back. How i detect the moment when i press ESC in a mapper form ?
