I want to limit the size of a list control box. Let us take the following code:
    import wx
    class Students(wx.Frame):
        def __init__(self, parent, id, title):
            wx.Frame.__init__(self, parent, id, title, size=(380, 230))
            hbox = wx.BoxSizer(wx.HORIZONTAL)
            panel = wx.Panel(self, -1)
            self.list = wx.ListCtrl(panel, -1, style=wx.LC_REPORT)
            self.list.InsertColumn(0, 'name')
            self.list.InsertColumn(1, 'age')        
            hbox.Add(self.list, 1,wx.EXPAND)
    app = wx.App()
    Students(None, -1, 'studs')
The result of above code is shown in picture below

If I make the horizontal box sizer's proportion=0 (as shown in the code snippet below):
    hbox.Add(self.list, 0,wx.EXPAND)
then the result of the code is shown in picture below:

The problem with proportion=1 is that after 'Age' column, there is a lot of empty space the list control box is eating up for the third column which doesn't exist.
The problem with proportion=0 is that it is too short in width.
I want to display the list control box with 'Name' and 'Age' columns only and save the rest of the space. How do I do that?
