[pygtk] DnD and resize

[Andre Lerche <a lerche gmx net>]

Hi!

I've a bit of a problem while programming with pygtk and I'll try
to explain it with the following little sample application:

#!/usr/bin/env python
import pygtk
import gtk as g

class dragTest (g.Window):
    def __init__(self):
    g.Window.__init__(self)
    self.set_size_request(100,100)
    self.__motion=False
    self.show()

    target = [("text/uri-list", 0, 0)]
    self.drag_dest_set(g.DEST_DEFAULT_ALL, target, g.gdk.ACTION_COPY)
    self.connect("drag-motion", self.dragMotion, None)
    self.connect("drag-leave", self.dragLeave, None)
    self.connect("destroy", g.main_quit)
    g.main()

    def dragMotion (self, widget, context, x, y, time, data):
        if not self.__motion:
            self.__motion = True
            self.set_size_request(300,300)
            self.queue_draw()
            while g.events_pending():
                g.main_iteration()
 
        print "Motion"

    def dragLeave (self, widget, context, time, data):
        print "Leave"

dragTest()

If I drag something over the window, the window gets resized to 300x300.
But if I move the "dragobject" out of the old 100x100 area, dragLeave
is called and dragMotion stops - why? Normally I thought that dragLeave
is called when I move the "dragobject" out of the 300x300 window or am
I wrong and/or miss some functions to announce the new window size?

It's pygtk 2.3.91 with Gtk 2.4.0

Thanks,

Andre
