Could someone give an example of using a hypertreelist

With TR_AUTO_CHILD and TR_AUTO_PARENT checkboxes?

I haven't been able to find an example thus far, and the wx demo did
now show those styles.

Thanks

Well, this depends on what you want to do: the 2 styles
TR_AUTO_CHECK_CHILD and TR_AUTO_CHECK_PARENT are useful only for
checkbox-type items. I am not sure what you are asking here, but a
simple constructor for HyperTreeList would be:

HyperTreeList.__init__(self, parent,
style=wx.TR_DEFAULT_STYLE|TR_AUTO_CHECK_CHILD|TR_AUTO_CHECK_PARENT )

Here's what I've tried.

from wx.lib.agw.hypertreelist import
(HyperTreeList,EVT_TREE_ITEM_CHECKED,EVT_TREE_ITEM_CHECKING)
from wx.lib.customtreectrl import
(TR_AUTO_CHECK_CHILD,TR_AUTO_CHECK_PARENT)
HyperTreeList.__init__(self,parent=inparent,style=TR_AUTO_CHECK_CHILD|
wx.TR_HIDE_ROOT | wx.TR_EDIT_LABELS | wx.TR_MULTIPLE |
wx.TR_FULL_ROW_HIGHLIGHT | wx.TR_HAS_BUTTONS| wx.TR_TWIST_BUTTONS |
wx.TR_NO_LINES)

When I add a new Item to the list (every item has a checkbox in column
0) the name of the item no longer show up and the checkboxes do not
automatically check/uncheck the children.

Also when I tried to import those styles from wx.lib.agw.hypertreelist
I received

ImportError: cannot import name TR_AUTO_CHECK_CHILD

Here's how I'm adding the checkboxes:

new_item = self.GetMainWindow().AppendItem(item,name)
new_checkbox = wx.CheckBox(self.GetMainWindow())
self.SetItemWindow(new_item,new_checkbox,0)
new_checkbox.Bind(wx.EVT_CHECKBOX, self.OnChecked)
new_checkbox.Bind(wx.EVT_UPDATE_UI, self.OnUpdate)
self.Bind(EVT_TREE_ITEM_CHECKED , self.OnItemChecked)

ImportError: cannot import name TR_AUTO_CHECK_CHILD

Here's how I'm adding the checkboxes:

new_item = self.GetMainWindow().AppendItem(item,name)
new_checkbox = wx.CheckBox(self.GetMainWindow())
self.SetItemWindow(new_item,new_checkbox,0)
new_checkbox.Bind(wx.EVT_CHECKBOX, self.OnChecked)
new_checkbox.Bind(wx.EVT_UPDATE_UI, self.OnUpdate)
self.Bind(EVT_TREE_ITEM_CHECKED , self.OnItemChecked)

No, no, no, don't do that! When I said "checkbox-type" items, I meant
that if you tell HyperTreeList that one item is checkbox-like it will
create the checkbox for it automatically, you don't have to append a
wx.CheckBox to it. For example (self is an HyperTreeList):

# ct_type=1 ==> checkbox-like item
item = self.AppendItem(parentItem, name, ct_type=1)

Also, do not use GetMainWindow() to append an item, GetMainWindow
should be used only while declaring a window associated to an item and
nowhere else. For example:

item = self.AppendItem(parentItem, name, ct_type=1)
textCtrl = wx.TextCtrl(self.GetMainWindow(), -1, "Hello")
self.SetItemWindow(item, textCtrl)

I received the error:

new_item = self.AppendItem(item,name,ct_type=1)
TypeError: AppendItem() got an unexpected keyword argument 'ct_type'

Any ideas as to fix this?

This is not possible. If you look at the wxPython demo you'll see a
couple of lines like that:

last = self.AppendItem(child, txt, ct_type=2)

Or:

last = self.AppendItem(child, txt, ct_type=1, wnd=textctrl)

So ct_type is there and working. Please show us a small runnable up
demonstrating the problem.
