[pygtk] Retrieve remaining column widths directly after removing column from treeview

[Calum Lind]

I have an issue where shutting down the application a remove_column method
is called just before saving the column state to a file which results in the
width data for all the columns being zero. Disabling the treeview
remove_column method the column width data is stored properly.

How do this width data get generated and is there any way to force this
update?

I have attached a code example.

Thanks

#!/usr/bin/env python

# example treeviewcolumn.py

import pygtk
pygtk.require('2.0')
import gtk

class TreeViewColumnExample:

    # close the window and quit
    def delete_event(self, widget, event, data=None):
        print "Quit Called, Column Width: %s" % self.tvcolumn1.get_width()
        self.treeview.remove_column(self.tvcolumn2)
        print "After removed another column, Column Width: %s" % self.tvcolumn1.get_width()
        gtk.main_quit()
        return False

    def __init__(self):
        # Create a new window
        self.window = gtk.Window(gtk.WINDOW_TOPLEVEL)
        self.window.set_title("TreeViewColumn Example")
        self.window.set_size_request(100, 100)
        self.window.connect("delete_event", self.delete_event)
        self.liststore = gtk.ListStore(str, str, str, 'gboolean')
        self.treeview = gtk.TreeView(self.liststore)
        self.tvcolumn = gtk.TreeViewColumn('Column')
        self.tvcolumn1 = gtk.TreeViewColumn('Column1')
        self.tvcolumn2 = gtk.TreeViewColumn('Column2')
        self.treeview.append_column(self.tvcolumn)
        self.treeview.append_column(self.tvcolumn1)
        self.treeview.append_column(self.tvcolumn2)
        self.window.add(self.treeview)
        print "Before window show, Column Width: %s" % self.tvcolumn1.get_width()
        self.window.show_all()
        print "After window show, Column Width: %s" % self.tvcolumn1.get_width()
        self.treeview.remove_column(self.tvcolumn)
        print "After removed column, Column Width: %s" % self.tvcolumn1.get_width()
