[pygtk] External activation of gtk.FileChooserButton

[Osmo Salomaa]

I want to have a filechooser button on a toolbar and an item in the
menubar that corresponds to it. How do I get the menu item to perform
the same function as what happens when the filechooser button is
clicked, which is running the filechooser dialog associated with the
filechooser button?

I assume that if I make the filechooser dialog an instance variable, I
can later call run() on it,

    def __init__(self):
        self.dialog = gtk.FileChooserDialog(...)
        self.button = gtk.FileChooserButton(dialog)
    ...
    def on_menu_item_activated(self, *args):
        self.dialog.run()
    
but I'd rather not have yet another instance variable. I tried the
activate() method and emitting button-press/release-events on the
filechooser button, but they did not work.

Below is a simple test app, where the menu item has been replaced by a
button. The "on_clicked" method is the part that needs modification.

Thanks,
Osmo Salomaa


#!/usr/bin/env python

import gtk

fcbutton = gtk.FileChooserButton('Select File')

def on_clicked(*args):
    fcbutton.activate() # Does not work.
button = gtk.Button('Activate file chooser button')
button.connect('clicked', on_clicked)

vbox = gtk.VBox()
vbox.pack_start(fcbutton)
vbox.pack_start(button)

window = gtk.Window()
window.set_default_size(400, 60)
window.add(vbox)
window.connect('delete-event', gtk.main_quit)
window.show_all()
gtk.main()
