How would you bind a button located within a hypertreelist?

[Dustin Hice]

Currently I'm trying to bind the button using the following inside of
the AppendItem function:

#Place the button in the hypertreelist
self.SetItemWindow(new_item,StatusButton(self.GetMainWindow(),"icons/
green_status16.png", "icons/yellow_status16.png","icons/
red_status16.png"),0)

#Bind the button to an event and function
self.Bind(wx.EVT_BUTTON,self.OnStatusButton,id=self.GetMainWindow
().GetItemWindow(new_item).GetId())

When AppendItem runs, I receive the following Message:

Traceback (most recent call last):
File "blade_gui.py", line 119, in newTestSuite
self.suite_list.AppendItem(self.suite_list.root,'Enter Test Suite
Name')
File "M:\blade_release\BLADE\gui\suite_list.py", line 32, in
AppendItem
self.Bind(wx.EVT_BUTTON,self.OnStatusButton,id=self.GetItemWindow
(new_item).GetId())
AttributeError: 'NoneType' object has no attribute 'GetId'

If GetItemWindow returns a NoneType, how to I access the individual
items?

My code below:

import sys
import wx
from wx.lib.agw.hypertreelist import HyperTreeList

sys.path.append("../process")
from suite import Suite
from step import Step
from seq import Sequence
from statusbutton import StatusButton

class SuiteList(HyperTreeList):

self.AddColumn('Status',width=42)
self.AddColumn('Test Suites',width=2000)
self.SetMainColumn(1)
self.root = self.AddRoot('Test Suites')
self.Bind(wx.EVT_RIGHT_UP, self.OnRightClick)

You should do something like this:

# Create the button
wnd = StatusButton(self.GetMainWindow(),"icons/green_status16.png",
"icons/yellow_status16.png","icons/red_status16.png")
# Bind the event
wnd.Bind(wx.EVT_BUTTON, self.OnStatusButton)
# Place the button in the hypertreelist
self.SetItemWindow(new_item, wnd, 0)

Thanks, that was extremely helpful.

I do however have one additional question. If I need to access a
member function of an item embedded in a hypertreelist, how would I go
about accessing it through the list?

Thanks

Dustin
