[wxpython-users] Re: wxTreeListCtrl

[ARCHER, Thomas]

Here's a quick app I knocked up. Notice how item 3 appears off to the side. 
Removing the image list solves this, but I need images, so that isn't practical.
Adding the style flag wx.TR_LINES_AT_ROOT seems to improve things (icons appear
in the right place) but leaves small horizontal dotted lines behind the text.
Maybe it's just a matter of getting the right combination of flags ;-).

Also, in terms of hiding the header, any ideas of how to attempt removing it?

Regards,
Tom

 
import wx
from wx import gizmos
class TreeTest(wx.Panel):
    def __init__(self, parent):
        wx.Panel.__init__(self, parent, wx.ID_ANY, size=(400,200))
        
        tree = gizmos.TreeListCtrl(self,style=wx.TR_HIDE_ROOT|wx.TR_HAS_BUTTONS|wx.TR_FULL_ROW_HIGHLIGHT , size=(400,200))        
        tree.AddColumn('Test')
        tree.AddColumn('Test1')
        self.root = tree.AddRoot('Root')
        treeItem = tree.AppendItem(self.root, 'Item1')
        treeItem2 = tree.AppendItem(treeItem, 'Item2')
        treeItem3 = tree.AppendItem(self.root, 'Item3')

        self.imgList = wx.ImageList(16,16)
        tree.AssignImageList(self.imgList)

app = wx.App()
frame = wx.Frame(None, -1, 'TreeTest')
TreeTest(frame)
frame.Show()
app.MainLoop()

There is a TODO comment in the code that says it would be nice to be
able to provide a style to do that, so I guess that means that is
hasn't been done yet.

Not sure.  Please make a small runnable sample that shows the problem.
