Reading Keyboard Input using AdaGtk

问题

I am using Ada together with the Gtk library. I would like to read the user's keyboard input and react individually on it, depending which keys he/she pressed. How can I access the keyboard input from the user?

回答1:

I'm not sure what you're looking for: 1) keystrokes or 2) editable text.

1. The game LinXtris handles main window key_press_event signals in the procedure On_Main_Window_Key_Pressed, which passes each Gdk.Event.Gdk_Event_Key on to the Game_Engine.

2. The Interaction demo cited here has a Gtk.Editable that handles Signal_Insert_Text in the procedure On_Insert_Text. The advantage is that the handler is called for single keystrokes, as well as pasted text.
