gizmos.TreeCtrl question

[Stefano Bartaletti]

Hello,

I am using a TreeListCtrl (as in the demo for TreeMixin) with 4 columns.
I want to resize the column labels with proportional values (like a Sizer 
does), so I wrote this function called in an OnSize event:

    def adjustColumns(self):
        props = (5,1,1,1)
        totProps = reduce(operator.add, props)
        
        maxSize = self.GetMainWindow().GetClientSize().x
        totSize = 0
        for idx, prop in enumerate(props):
            newSize = (maxSize * prop) / totProps
            self.SetColumnWidth(idx, newSize)
            totSize += newSize
        # Last column should get any spare size
	self.SetColumnWidth(idx, newSize + (maxSize - totSize))

It works fine except that the rightest Column is overlapped by a Scrollbar if 
I start with a small list and then expand one or more items, so I tried 
forcing a CallAfter to this function in an OnExpandItem

The call to self.GetMainWindow().GetClientSize() always gives me the size of 
the ScrolledWindow inside the Tree withouth taking Scrollbars into its 
calculation

I have tried forcing Refresh/Layout on the Tree window and on the 
GetMainWindow() object before GetClientSize() with no luck.

How do I get the correct result? Is there any special event I should handle or 
am I using data from the wrong Window?

Thanks for any tip
