[pygtk] Best pattern for keyboard accelerators in dialog
Hi I have a Window that has a number of widgets placed in it, including a TreeView, a Frame (containing more widgets), buttons etc. The Frame contains a table with Labels, CheckButton and Edit widgets. I would like to provide keyboard accelerators that move the focus to the appropriate Widget. I want to underline a letter in each label and link Alt-letter to switch to the Edit widget alongside the Label. I would like these accelerators to work regardless of which widget has the focus. I would really like to keep the handling of these accelerators inside the abstractions of the sub-widgets. The Frame is implemented as a subclass of gtkFrame and I want to be able to plug in different Frames into the main Window with different keybindings. Is there a good pattern for coding this type of thing or an example of another app that I can take a look at?

Hi,
does this help you?
http://www.pygtk.org/pygtk2tutorial/sec-WidgetAccelerators.html
18.3. Widget Accelerators
The following methods:
widget.add_accelerator(accel_signal, accel_group, accel_key, accel_mods,
accel_flags)
widget.remove_accelerator(accel_group, accel_key, accel_mods)
add and remove accelerators from a gtk.AcceleratorGroup that must be attached
to the top level widget to handle the accelerators.
The accel_signal is a signal that is valid for the widget to emit.
The accel_key is a keyboard key to use as the accelerator.
The accel_mods are modifiers to add to the accel_key (e.g. Shift, Control,
etc.):
SHIFT_MASK
LOCK_MASK
CONTROL_MASK
MOD1_MASK
MOD2_MASK
MOD3_MASK
MOD4_MASK
MOD5_MASK
BUTTON1_MASK
BUTTON2_MASK
BUTTON3_MASK
BUTTON4_MASK
BUTTON5_MASK
RELEASE_MASK
The accel_flags set options about how the accelerator information is
displayed. Valid values are:
ACCEL_VISIBLE # display the accelerator key in the widget display
ACCEL_LOCKED # do not allow the accelerator display to change
An accelerator group is created by the function:
accel_group = gtk.AccelGroup()
The accel_group is attached to a top level widget with the following method:
window.add_accel_group(accel_group)
An example of adding an accelerator:
menu_item.add_accelerator(activate, accel_group,
ord('Q'), gtk.gdk.CONTROL_MASK, gtk.ACCEL_VISIBLE)

I had read this documentation but I could not work out the correct pattern for
making use of it.
So the principle is to use 'add_accelerator' on each of the widgets that I
want to be activated by keypress and then somehow agregate the accel_groups
up to the top level widget?
Or is it better to construct the accel_group in the top level window and pass
it in to the constructor of all the sub widgets, using it in the calls to
add_accelerator on each of the sub widgets?
Does anyone have an example of doing this?
Thanks again.
Richard
