[pygtk] Re: custom popup dialog

[Michael Baranov]

Here is a small standalone snippet illustrating of the problem.

The allocation for each of the  2 entries does *not* reflect the actual =

on-screen size of  the widgets, but rather the space allocated for them =

by the container. Can somebody tell me what's happening? Why the entries =

are not resized to their allocations? How to solve my problem? Thanks!!!

#start
import gobject
import pygtk
pygtk.require('2.0')
import gtk

def on_focus_in(widget, event):
    allocation =3D widget.get_allocation()
    print allocation.x, allocation.y, allocation.width, allocation.height

if(__name__ =3D=3D "__main__"):
    window =3D gtk.Window(gtk.WINDOW_TOPLEVEL)
    window.set_size_request(200, 100)
    window.set_title("GTK Entry")
    window.connect("delete_event", lambda w, e: gtk.main_quit())

    entry1 =3D gtk.Entry()
    entry2 =3D gtk.Entry()
   =

    entry1.connect("focus-in-event", on_focus_in)
    entry2.connect("focus-in-event", on_focus_in)

    box =3D gtk.VBox()
    window.add(box)

    box.add(entry1)
    box.add(entry2)

    window.show_all()
    window.show()
    gtk.main()
