Adding other widgets to gtk.Menu

Question

I would like gtk.ProgressBar to be added to gtk.Menu, but since there are only gtk.MenuItems and its subclasses in the menu, I instead made a simple gtk.MenuItem and tried to add my progress as a child to this. Since gtk.MenuItem is a subclass of gtk.Bin, it should be able to store almost any widget.

Example:

menu = gtk.Menu() item = gtk.MenuItem() button = gtk.ProgressBar() button.pulse() button.show() item.add(button) item.show() menu.append(item) 

This works fine even if the pigt doesn't complain at all. However, my progress bar is simply not shown:

If I replaced the progress indicator with gtk.Label, it showed that it was just fine.

Now to my questions:

• How to find out which widgets you need?
• How can I trick him into letting me post other widgets there?

Answer 1

This is a limitation of Ubuntu application indicators, see this question in askubuntu .

Answer 2

Your sample code works here (I tested it by modifying the pygtk example, which I will embed below).

Maybe this is a problem with the rest of your code or your theme?

 #!/usr/bin/env python # example menu.py import pygtk pygtk.require('2.0') import gtk class MenuExample: def __init__(self): # create a new window window = gtk.Window(gtk.WINDOW_TOPLEVEL) window.set_size_request(200, 100) window.set_title("GTK Menu Test") window.connect("delete_event", lambda w,e: gtk.main_quit()) # Init the menu-widget, and remember -- never # show() the menu widget!! # This is the menu that holds the menu items, the one that # will pop up when you click on the "Root Menu" in the app menu = gtk.Menu() ### MODIFIED PART!! ### item = gtk.MenuItem() button = gtk.ProgressBar() button.pulse() button.show() item.add(button) item.show() menu.append(item) #### END MODIFIED PART #### # This is the root menu, and will be the label # displayed on the menu bar. There won't be a signal handler attached, # as it only pops up the rest of the menu when pressed. root_menu = gtk.MenuItem("Root Menu") root_menu.show() # Now we specify that we want our newly created "menu" to be the # menu for the "root menu" root_menu.set_submenu(menu) # A vbox to put a menu and a button in: vbox = gtk.VBox(False, 0) window.add(vbox) vbox.show() # Create a menu-bar to hold the menus and add it to our main window menu_bar = gtk.MenuBar() vbox.pack_start(menu_bar, False, False, 2) menu_bar.show() # Create a button to which to attach menu as a popup button = gtk.Button("press me") button.connect_object("event", self.button_press, menu) vbox.pack_end(button, True, True, 2) button.show() # And finally we append the menu-item to the menu-bar -- this is the # "root" menu-item I have been raving about =) menu_bar.append (root_menu) # always display the window as the last step so it all splashes on # the screen at once. window.show() # Respond to a button-press by posting a menu passed in as widget. # # Note that the "widget" argument is the menu being posted, NOT # the button that was pressed. def button_press(self, widget, event): if event.type == gtk.gdk.BUTTON_PRESS: widget.popup(None, None, None, event.button, event.time) # Tell calling code that we have handled this event the buck # stops here. return True # Tell calling code that we have not handled this event pass it on. return False # Print a string when a menu item is selected def menuitem_response(self, widget, string): print "%s" % string def main(): gtk.main() return 0 if __name__ == "__main__": MenuExample() main()
