I have the standard:
from RegWindow import *

rw=RegWindow(self.scroll, ID=-1, Registration=rg,
(rg.Rg_SeNo))
weekoverviewSizer.Add(rw, pos=(srow,col), span=(erow,1),
flag=wx.EXPAND)
self.scroll.SetSizer(weekoverviewSizer)
self.scroll.SetupScrolling(self, rate_x=20, rate_y=50)
fullsize=wx.Size(1000,900)
self.Centre()
class App(wx.App):

self.frame = main_window(None, 'Planning Assistant')

When a room is selected in the context sensitive menu. The RegWindow is
moved to another spot in the sizer. Then the screen needs to be
refreshed. If I do it manually by resizing or by maximizing, everything
looks K, but I want to do it programmatically. The problem is that from
within the RoomSelected handler I cannot get a reference to the frame.
Do I have to import the main module into RegWindow.py? That seems like
spaghetti to me, two modules each importing the other and it doesn't
work then either. With something that is contained in a sizer, it's
possible to get the containing sizer object, but there is no method on
the sizer object to obtain the containing panel object.
I hope somebody can help me with this and I also hope I didn't take out
too much of code for the example. I tried to just post the essential
bits to show what I'm trying to achieve.
Kind regards,
Jo

Hi Jo,

instead of:
app.frame.Refresh()

you could do:
wx.GetApp().frame.Refresh()

in your app you set the topwindow:

self.frame.Show(True)
self.SetTopWindow(self.frame)

wx.GetTopWindow().Refresh()

Did not try this out, but hopefully it is enough to get you going.

Hi Robin,

That did the trick. Now the window is redrawn correctly, but the sizer
still behaves erratically (didn't mention that yet). When I detach a
RegWindow and then place it somewhere else, it happens very often that a
lot of sizer cells are added on top and very rarely on the left.
Maximizing the window solves this. When the window is maximized, putting
it back to Window mode solves it too. So the app/window/sizer knows how
it should be, but it doesn't actually do what it's supposed to do. Maybe
I should maximize the screen programmatically and then put it back to
where it was?

Many thanks for your answer and also for the great book which I'm using
extensively.

Jo

Hi Werner,

It certainly put me on the right track. Many thanks,

Jo
