In this article we are going to learn about EditLabel() method associated with wx.TreeCtrl class of wxPython. Starts editing the label of the given item.
This function generates a EVT_TREE_BEGIN_LABEL_EDIT event which can be vetoed so that no text control will appear for in-place editing.
If the user changed the label (i.e. s/he does not press ESC or leave the text control without changes, a EVT_TREE_END_LABEL_EDIT event will be sent which can be vetoed as well.
Syntax: wx.TreeCtrl.EditLabel(self, item)
Parameters:
Parameters Type Description item wx.TreeItemId Item that we want to associate editlabel with.
Code Example:
Python3
import wx class MyTree(wx.TreeCtrl): def __init__(self, parent, id, pos, size, style): wx.TreeCtrl.__init__(self, parent, id, pos, size, style) class TreePanel(wx.Panel): def __init__(self, parent): wx.Panel.__init__(self, parent) # create tree control in window self.tree = MyTree(self, wx.ID_ANY, wx.DefaultPosition, wx.DefaultSize, wx.TR_HAS_BUTTONS) # CREATE TREE ROOT self.root = self.tree.AddRoot('root') self.tree.SetPyData(self.root, ('key', 'value')) # add item to root item = self.tree.AppendItem(self.root, "Item") item2 = self.tree.AppendItem(self.root, "Item") # expand root self.tree.Expand(self.root) # start editlabel self.tree.EditLabel(item2) sizer = wx.BoxSizer(wx.VERTICAL) sizer.Add(self.tree, 0, wx.EXPAND) self.SetSizer(sizer) class MainFrame(wx.Frame): def __init__(self): wx.Frame.__init__(self, parent = None, title ='TreeCtrl Demo') panel = TreePanel(self) self.Show() if __name__ == '__main__': app = wx.App(redirect = False) frame = MainFrame() app.MainLoop() |
