[wxPython-users] Another sizer question

[Alun Griffiths]

Christopher

thanks again for your help.  I just spotted that PlotFrame was based 
on a wx.Frame and not a wx.Panel and have modified the code 
accordingly - that was a big improvement!!  Also changed some of the 
code so that I am ALMOST there - the only problem I now have is that 
the text boxes are on the frame (dark grey in Windows) whereas I 
would like to put them on a panel and have not managed to work out 
how to add a sizer to a panel.  What I would like to do is (a) add 
the text control widgets to LHSIZER (already done) (b) add LHSIZER to 
PANEL (don't know how to do this) then (c) add the PANEL to the box 
sizer BOX.  Revised code is attached

As regards WXMPL, I did use this before but it does not come as part 
of the ENTHOUGHT edition which has been installed on the university 
server.  I though the DIY approach would be easier than hoop-jumping 
associated with getting an "unofficial" package installed on the server.

Best regards

Alun Griffiths
