Sizer

Hello everybody,

I am just new to this group and to wxPython, i am french and I apologize for my poor English.

I want to have a main window with sliders and a “More controllers” button on it.

When I click on “More controllers” button a subwindow open showing others sliders.

My problem is if I use the sizer method on the subwindow I can’t see any sliders on this subwindow !!

Have included the file Sizer_test.py, a “reduced” (no button) version for test.

Normally it should display a main window with two sliders and a subwindow with two sliders.

I can’t find my mistake. (I am on Ubuntu 10.04 with wxpython 2.8)

Thanks for help

Hello Djack,

On Windows XP SP3, wxPython 2.8.11.0 and Python 2.6, the 2 windows
show up
without problem although a little small.
I can see the 2 sliders.

Anyway, I think you should:
- attach your gridbagsizer to the panel instead of self in the
subwindow,
panel.SetSizer(sizer1)
- add panel.Fit()
- increase the size of your subwindow,
I never put SetSizeHints, but I may be wrong !! I am not a
professionnal!

Hi Djack,

here is your code with the small corrections.
Test on Windows 7, wxPython 2.8.11.0 and Python 2.7.

#!/usr/bin/python
# -*- coding: latin-1 -*-

import wx

class Sub_Window(wx.Frame):
    def __init__(self, parent, size=(200,200), position=(300,300)):
        wx.Frame.__init__(self, parent, -1, title="Sub Window",
size=size, pos=position)

        panel = wx.Panel(self, -1)
        self.GrAmpCtrl = wx.Slider(panel, -1, 250, 0, 400, (0, 0),
(90,35), wx.SL_HORIZONTAL | wx.SL_LABELS )
        self.GrFreqCtrl = wx.Slider(panel, -1, 14, 1, 1500, (0, 0),
(90,35), wx.SL_HORIZONTAL | wx.SL_LABELS )

        sizer1 = wx.GridBagSizer(10, 10)
        sizer1.Add(self.GrAmpCtrl, (2,1))
        sizer1.Add(self.GrFreqCtrl, (4,1))
        sizer1.SetSizeHints(panel) ##### panel
        panel.SetSizer(sizer1) ##### panel

class GUI(wx.Panel):
    def __init__(self, parent):
        wx.Panel.__init__( self, parent, -1)

        self.GrAmpCtrl = wx.Slider(self, -1, 250, 0, 400, (0, 0),
(90,35), wx.SL_HORIZONTAL | wx.SL_LABELS )
        self.GrFreqCtrl = wx.Slider(self, -1, 14, 1, 1500, (0, 0),
(90,35), wx.SL_HORIZONTAL | wx.SL_LABELS )

        sizer1 = wx.GridBagSizer(10, 10)
        sizer1.Add(self.GrAmpCtrl, (2,1))
        sizer1.Add(self.GrFreqCtrl, (4,1))
        sizer1.SetSizeHints(self)
        self.SetSizer(sizer1)
        window = Sub_Window(parent, (300,300), (800,0))
  window.Show(True)

application = wx.PySimpleApp()
frame = wx.Frame( None, -1, "Main Window", pos=(0,0))
guiMain = GUI(frame)

frame.Show(True)
application.MainLoop()

Good continuation,
CJC.

You should assign the sizer to the panel, not to self. The items being managed by the sizer are children of the panel, and so it is the panel who should be responsible for their layout, so it is the panel that needs the sizer with those items in it.
