ActionHandler constructor.

Create the main window, setup the message handler, import the preferences,

and connect all of the action handlers. Finally, enter the gtk main loop and block.

Args:

file_paths: a list of flow graph file passed from command line

platform: platform module

* some keys are ignored by the accelerators like the direction keys,

* some keys are not registered to any accelerators but are still used.

When not in focus, gtk and the accelerators handle the the key press.

Returns:

false to let gtk handle the key action

"""

Handle the delete event from the main window.

Generated by pressing X to close, alt+f4, or right click+close.

This method in turns calls the state handler to quit.

Returns:

true
