Programmatic binding of accelerators in wxPython
- by Inductiveload
I am trying to programmatically create and bind a table of accelerators in wxPython in a loop so that I don't need to worry about getting and assigning new IDs to each accelerators (and with a view to inhaling the handler list from some external resource, rather than hard-coding them). I also pass in some arguments to the handler via a lambda since a lot of my handlers will be the same but with different parameters (move, zoom, etc).
The class is subclassed from wx.Frame and setup_accelerators() is called during initialisation.
def setup_accelerators(self):
bindings = [
(wx.ACCEL_CTRL, wx.WXK_UP, self.on_move, 'up'),
(wx.ACCEL_CTRL, wx.WXK_DOWN, self.on_move, 'down'),
(wx.ACCEL_CTRL, wx.WXK_LEFT, self.on_move, 'left'),
(wx.ACCEL_CTRL, wx.WXK_RIGHT, self.on_move, 'right'),
]
accelEntries = []
for binding in bindings:
eventId = wx.NewId()
accelEntries.append( (binding[0], binding[1], eventId) )
self.Bind(wx.EVT_MENU, lambda event: binding[2](event, binding[3]), id=eventId)
accelTable = wx.AcceleratorTable(accelEntries)
self.SetAcceleratorTable(accelTable)
def on_move(self, e, direction):
print direction
However, this appears to bind all the accelerators to the last entry, so that Ctrl+Up prints "right", as do all the other three. How to correctly bind multiple handlers in this way?
