wx.Dialog and sizers

wxPython Users

i'm using the following code as a test:

        panel = wx.Panel(self, -1)
        panel.SetBackgroundColour('#4f5049')
        vbox = wx.BoxSizer(wx.VERTICAL)

        midPan = wx.Panel(panel, -1)
        midPan.SetBackgroundColour('#ededed')

        vbox.Add(midPan, 1, wx.EXPAND | wx.ALL, 20)
        panel.SetSizer(vbox)
        self.Centre()
        self.Show(True)

it works fine in my main application, but it does nothing in the
wx.Dialog that i call. what am i doing wrong?

thanks,
bob k.

ps (wxPython in Action is on the way, but i don't have it yet)

Bob,

i'm using the following code as a test:

         panel = wx.Panel(self, -1)
         panel.SetBackgroundColour('#4f5049')
         vbox = wx.BoxSizer(wx.VERTICAL)

         midPan = wx.Panel(panel, -1)
         midPan.SetBackgroundColour('#ededed')

         vbox.Add(midPan, 1, wx.EXPAND | wx.ALL, 20)
         panel.SetSizer(vbox)
         self.Centre()
         self.Show(True)

it works fine in my main application, but it does nothing

You mean you don't see these two panels or ......?

in the
wx.Dialog that i call. what am i doing wrong?

Just pasted above code into a dialog and run it and looks fine to me. Can you attach the the file with the wx.Dialog you did.

Are you doing anything to manage the size/position of the first panel? Have you added it to a sizer that is assigned to self?

I seem to recall that on one platform that a dialog doesn't get an initial size event like frames do, so that may be part of the problem as well. So you may need to do something to help force the initial layout, like calling self.SendSizeEvent or self.Layout.

Robin,

i've changed the code to:

        # panels
        panel = wx.Panel(self, -1)
        panel.SetBackgroundColour('#4f5049')
        vbox = wx.BoxSizer(wx.VERTICAL)

        midPan = wx.Panel(panel, -1)
        midPan.SetBackgroundColour('#ededed')

        vbox.Add(midPan, 1, wx.EXPAND | wx.ALL, 20)
        #panel.SetSizer(vbox)
        panel.SetSizerAndFit(vbox)
        panel.Layout()

the display now is visible, but it' a small portion of the wx.Dialog
(the upper left corner). in the main wx.Frame app it uses the entire
frame.

What about the attached, i.e. add a sizer to the dialog and add the panel to that sizer and then call Layout on the dialog.
