void PandaFramework::set_exit_flag ( ) [inline]

Sets the flag that indicates it is time for the application to exit.

The application will actually exit at the end of the current frame.

Certain operations affect the highlighted node only.

void PandaFramework::set_recorder ( RecorderController recorder) [inline]

Assigns a RecorderController with the PandaFramework.

This should be called before any windows are opened. The subsequently opened windows will register their user inputs with the recorder.

If a RecorderController is associated, it will presumably be used for recording user input to a session file, or for playing back the user input from a previously-recorded session.
