No key events for linux application without desktop environment
I have an application that runs on Ubuntu 12.04 without desktop environment. The application opens some popup dialogs. In these popup dialogs I am not able to grab key events. It seems that these key events are not passed to the dialog but they are also not send to the main window. If I run the same application with a desktop environment everything works as expected.
Is there a way to pass key events to dialogs when no desktop environment is present?
may be exporting QWS_KEYBOARD would help ...
