    <p>I'm using wx.aui to build my user interface. I'm defining a class that inherits from wx.Panel and I need to change the content of that panel when its window pane is resized.</p> <p>I'm using code very similar to the code below (which is a modified version of sample code found <a href="https://stackoverflow.com/questions/523363/how-do-i-layout-a-3-pane-window-using-wxpython/532873#532873">here</a>).</p> <p>My question is: is there a wx.Panel method being called behind the scenes by the AuiManager that I can overload? If not, how can my ControlPanel object know that it's being resized?</p> <p>For instance, if I run this code and drag up the horizontal divider between the upper and lower panes on the right, how is the upper right panel told that its size just changed? </p> <pre><code>import wx import wx.aui class ControlPanel(wx.Panel): def __init__(self, *args, **kwargs): wx.Panel.__init__(self, *args, **kwargs) class MyFrame(wx.Frame): def __init__(self, *args, **kwargs): wx.Frame.__init__(self, *args, **kwargs) self.mgr = wx.aui.AuiManager(self) leftpanel = ControlPanel(self, -1, size = (200, 150)) rightpanel = ControlPanel(self, -1, size = (200, 150)) bottompanel = ControlPanel(self, -1, size = (200, 150)) self.mgr.AddPane(leftpanel, wx.aui.AuiPaneInfo().Bottom()) self.mgr.AddPane(rightpanel, wx.aui.AuiPaneInfo().Left().Layer(1)) self.mgr.AddPane(bottompanel, wx.aui.AuiPaneInfo().Center().Layer(2)) self.mgr.Update() class MyApp(wx.App): def OnInit(self): frame = MyFrame(None, -1, '07_wxaui.py') frame.Show() self.SetTopWindow(frame) return 1 if __name__ == "__main__": app = MyApp(0) app.MainLoop() </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
