[pygtk] key press handling... HELP!!!

[days_of_ruin]

self.window.connect("key-press-event",self.on_window_key_press_event)
Okay so I have the window handle key press events


def on_window_key_press_event(self,window,event):
print event.state
if event.state == gtk.gdk.MOD2_MASK:
print "Control"
if event.keyval == 122:
print "z":w


But no matter what key I press the console always prints

<flags GDK_MOD2_MASK of type GdkModifierType>
Control

Why does it do that??

Okay I still have no idea what MOD2_MASK means but I figured out how to
tell if the user pressed control + z

if event.keyval == 122:
if event.state == gtk.gdk.CONTROL_MASK | gtk.gdk.MOD2_MASK:
print "Control + z"


Is there a gtk.gdk key constants for a-z? To make the code more readable.

Sorry for late reply :) The reason you got both of lines printed is because Control is a key too, so event was first fired when user pressed Control key and later for Z too. :) Under event.state you have bit mask representing state of modifiers (ALT, SHIFT, SUPER, CONTROL... etc.).



import gtk.gdk

def click_event(self, widget, event):
print gtk.gdk.keyval_name(event.keyval)


This will give you output like "Control_L", "Tab", "z", "s"

Hope this helps!

In my system, GDK_MOD2_MASK is mapped to the numerical lock.

You can run xmodmap to see the keymap table of your system.
