After some more digging i found a way to do it:

    import wx

    def on_initialize(self, event):
        self.components.thelist.columnHeadings = dat.headings
        self.components.thelist.items = dat.values()
        self.autoSizeColumns()
        self.updating = False

    def autoSizeColumns(self):
        for col in range(len(dat.headings)):
            self.components.thelist.SetColumnWidth(col, wx.LIST_AUTOSIZE)      
     

and call this on any update of thelist. I wonder if i can do it in one
central place.

Cheers,
