wxTreeCtrl

I've created a TreeCtrl class
*class MyTreeCtrl(wxTreeCtrl):
    def __ini__(self,parent,id,pos,size):
        wxTreeCtrl.__init__(self,parent,id,pos,size
        #now I want to add a item
        self.root = self.AddRoot("Root item")

*but this doesn't work
I have to make an instance of the class and then do : self.root = self.instanceofclass.AddRoot("Root item")
Is it possible to add items in the class self ?

First of all, there are a couple of typographical errors, but I
assume that you did not copy and paste, because the code as posted
should not even run at all.

Secondly, self.root = self.AddRoot("Root item") should work fine,
but technically this statement adds a root item *to each instance*
not to the class. The object "self" is the instance that is being
initialized by the __init__ method at instantiation.

Regards,

For me it doesn't work
here is my code this time I copy past it
*class MyTreeCtrl(wxTreeCtrl):
    def __ini__(self,parent,id,pos,size):
        wxTreeCtrl.__init__(self,parent,id,pos,size)
        self.root = self.AddRoot("Root item")
        return 1

*I make an instance of the class in my frame like this
*self.treeCtrl = MyTreeCtrl(splitter,-1,wxDefaultPosition,wxDefaultSize);*

Try this:

class MyTreeCtrl(wxTreeCtrl):
    def __init__(self,parent,id):
        wxTreeCtrl.__init__(self,parent,id)
        self.root = self.AddRoot("Root item")

class MyFrame(wxFrame):
    def __init__(self):
        wxFrame.__init__(self, None, -1, 'Tree Test',
                         size=(200,200))
        self.tc1 = MyTreeCtrl(self, -1)
        self.tc1.AppendItem(self.tc1.root, 'test1')

class MyApp(wxApp):
    def OnInit(self):
        frame = MyFrame()
        frame.Show(true)
        return true

if __name__ == '__main__':

    app = MyApp(0)
    app.MainLoop()

Constructors are named "__init__" (with a "t"; not "__ini__").

Also, __init__ should not return anything (if you fix the "__ini__"
typo, the interpreter will tell you this ;))
