Capture Right Click events in pygtk
If you pass in the event when you enter a callback, you can look at event.type to determine which button was pushed and process the action accordingly.
If you’re only interested in the right-click, say for a menu popup for example, check for event.button equal to three.
|
1 2 3 4 |
def tv_event_cb(widget, event): if event.type == gtk.gdk.BUTTON_PRESS: if event.button != 3: return False |
Make sure to check the event.type first for a button press as not all events will define an event.button.
Here’s an example of catching right clicks on a treeview:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 |
#!/usr/bin/env python import gtk class Example: def __init__(self): window = gtk.Window(gtk.WINDOW_TOPLEVEL) window.set_size_request(200,200) store = gtk.ListStore(str) store.append([ 'rootninja' ]) cell = gtk.CellRendererText() tvcol = gtk.TreeViewColumn('col0') tvcol.pack_start(cell, True) tvcol.add_attribute(cell, 'text', 0) tv = gtk.TreeView(store) tv.connect('event', self.tv_cb) tv.append_column(tvcol) window.add(tv) window.connect("destroy", gtk.main_quit) window.show_all() def tv_cb(self, tv, event): if event.type == gtk.gdk.BUTTON_PRESS: if event.button != 3: return else: print "right button pressed" Example() gtk.main() |
In this case, connecting the broad ‘event’ enables my callback to use event without having to pass it in, however, most signals all you to specify any arguments you want.
