Resizing a SpliterWindow

wxPython Users
1

I haven’t been able to figure out how to control which part of a
SplitterWindow is changed on a window resize. My application is split
into a top panel and bottom panel. The top panel is the main
application, and the bottom panel displays status messages. When user
resizes a
window, I want the extra space to go into the top panel.

Everything
I have tried so far has the bottom panel resizing. I have tried several
things with sizers to no avail. Obviously the user could change the
splitter, but I know resizing can be made to work because I see
applications do it (e.g., PyCrust) I just haven’t found the secret.

Here is the simple example. When the user resizes, the bottom panel changes size, I want the top panel to change.

import wx

class MyFrame(wx.Frame):
def init(self, *args, **kwargs):

    wx.Frame.__init__(self, *args, **kwargs)

    splitter = wx.SplitterWindow(self)

   
    top = wx.Window(splitter, style=wx.BORDER_SUNKEN)
    wx.StaticText(top, -1, "Top Panel", (5,5))
    bottom = wx.Window(splitter, style=wx.BORDER_SUNKEN)

    wx.StaticText(bottom, -1, "Bottom Panel", (5,5))

    splitter.SplitHorizontally(top, bottom, -100)

    splitter.SetMinimumPaneSize(20)

    splitter.SplitHorizontally(toppane, bottompane, -100)

app = wx.PySimpleApp()

frame = MyFrame(None)
frame.Show()

app.MainLoop()

Add this line:
splitter.SetSashGravity(1.0)
