import wxclass MainFrame(wx.Frame): def __init__(self): wx.Frame.__init__(self, parent = None, title ='TreeCtrl Demo') # tree control self.tree = wx.TreeCtrl(self, wx.ID_ANY, wx.DefaultPosition, wx.DefaultSize) # create imagelist il = wx.ImageList(16, 16) # add images to image list one = il.Add(wx.Image('plus.png', wx.BITMAP_TYPE_PNG).Scale(16, 16).ConvertToBitmap()) two = il.Add(wx.Image('close.png').Scale(16, 16).ConvertToBitmap()) # assign image list to tree self.tree.AssignImageList(il) # add a root node to tree self.root = self.tree.AddRoot('Root ', 0) # add item to self.root self.tree.AppendItem(self.root, "Item", 1) # expand tree self.tree.Expand(self.root) # show frame self.Show()if __name__ == '__main__': app = wx.App(redirect = False) frame = MainFrame() app.MainLoop() |
