In the program below, the main window's central widget is a QFrame

QFrame). Pressing the "Create work panel" button inserts another
QFrame above the CtrlPanel, causing the main window to grow
vertically. Pressing the "Remove work panel" button removes the work
panel, which *should* cause the main window to shrink vertically to
its original size.
But the main window does not shrink automatically (using CHOICE = 0 in
line 74). Method MainWin.fix_size() should force the main window to
shrink, but simply invoking this method after removing the work panel
(CHOICE = 1) does not have the desired effect. The only thing that
works for me is using a QTimer to invoke MainWin.fix_size() after a
short delay (CHOICE = 2).
Note: I also tried invoking update() on various objects -- no luck there.
Can anyone provide some insight into what's going on and/or what I'm
doing wrong?
Environment: Python 2.6.5; QtCore.qVersion() == 4.5.3
Many thanks,
John

Hi,
Change this def :
def fix_size(self):
"""change window size after removing work panel"""
self.ctrlpanel.resize(*self.ctrlpanel.smallsize)
C.QCoreApplication.processEvents()
self.resize(*self.ctrlpanel.smallsize)
and :
elif CHOICE == 1:
# DOES NOT WORK: resize main window immediately
C.QCoreApplication.processEvents()
self.mainwin.fix_size()
use CHOICE = 1

Merci bien, Vincent. Using processEvents() works fine in the test
program I submitted.
But here's an interesting wrinkle: when I change the test program to
invoke fix_size() via signal/slot instead of a direct call, things work
fine. The large application from which I abstracted the test program
uses signal/slot to call fix_size(). When I applied your change to the
large application, the resizing does not work. Changing from signal/slot
to a direct call *does* work, so I'm happy now (if still a little confused).
