python-keybinder and right hotkey string

Question

Python-keybinder is used to set global hotkeys in my program. GtkToggleButton widget is used to retrieve keybinding from user (key-press-event/key-release-event).

User presses togglebutton and presses some keys (Left Control + t, f.e.). Togglebutton`s event (key-press-event) returns "Control_L" and "t". Program saves this into string "t" and calls keybinder.bind("t", callback). User presses that hotkey and ... nothing happens. I found strange thing after some time of digging - keybinder understands "Control" (without _L/_R), "Alt" etc, and does not understand "Control_L", "Alt_L"... Documentation says next:

Text from python-keybinder documentation:

bind(...)
    bind (keystring, callback, user_data) -> bool

    Keystring should be in the format understood by
    gtk.accelerator_parse. An example is '<Ctrl>space'.

Text from gtk/gtkaccelgroup.c:

• gtk_accelerator_parse: *
• Parses a string representing an accelerator. The
• format looks like "<Control>a" or "<Shift><Alt>F1" or
• "<Release>z" (the last one is for key release).
• The parser is fairly liberal and allows lower or upper case,
• and also abbreviations such as "<Ctl>" and "<Ctrl>".
• Key names are parsed using gdk_keyval_from_name().

Text from gdk/gdkkeynames.c:

• gdk_keyval_from_name: *
• Converts a key name to a key value. *
• The names are the same as those in the
• <gdk/gdkkeysyms.h> header file
• but without the leading "GDK_KEY_".

Ok, and at last text from gdk/gdkkeysyms.h:

205 #define GDK_KEY_Control_L 0xffe3
206 #define GDK_KEY_Control_R 0xffe4

How can I set and use keybinder without replacing "Control_L" to "Control", "Alt_L" to "Alt" and etc?

Upd: Linux, Python 2.4-2.7

Upd2: I want to see difference between "left control" and "right control" and use these keys as different buttons. How can I do this with gtk.accelerator_parse()? Is there a way?

Thnx.

Answer 1

Just to add an example to the accepted answer, here is the python code solved my problem:

>>> import gtk
>>> gtk.accelerator_name(ord(';'),gtk.gdk.MOD1_MASK)
'<Alt>semicolon'

The function documentation is at http://www.pygtk.org/pygtk2reference/class-gtkaccelgroup.html#function-gtk--accelerator-name

The modifier constants are at: http://www.pygtk.org/pygtk2reference/gdk-constants.html#gdk-modifier-constants.

Answer 2

GTK offers GtkCellRendererAccel for setting keybindings, this might be easier as you wont have to worry about converting between the two key description formats.
