[Tkinter-discuss] Fwd: Tix hlist-clearing selection

[hani abraham]

Yes, i used the hlist component of the tree but nothing happens. The thing is I can clear the selection if I use selection_set then selection_clear but i can't clear the selection when it's highlight with a mouse.

Thanks, 
Hani

Hey Hani,

Are you sure you are calling the selection_clear method of the hlist child widget and not the parent tree?

eg.
tree = Tix.Tree(root)
tree.hlist.selection_clear ()

If you look in Tix.py you can see that Tree is a compound widget containing two scrollbars and a hlist. 

class Tree(TixWidget):
    def __init__(self, master=None, cnf={}, **kw):
        TixWidget.__init__(self, master, 'tixTree',
                           ['options'], cnf, kw)
        self.subwidget_list ['hlist'] = _dummyHList(self, 'hlist')
        self.subwidget_list['vsb'] = _dummyScrollbar(self, 'vsb')
        self.subwidget_list['hsb'] = _dummyScrollbar(self, 'hsb') 

Thus to clear the hlist selection you must address the child hlist directly and not its parent Tree widget.

Cheers,
James

Hi, 
 
I'm new to python and i'm using Tix Tree widget in my application. I'm trying to clear the tree selection but no luck so far. I tried selection_clear and anchor_clear but these aren't working. Can someone help?
