combotreebox

ComboTreeBox provides a ComboBox that pops up a tree instead of a list.

ComboTreeBox tries to provide the same interface as ComboBox as much as possible. However, whereas the ComboBox widget uses indices to access items in the list of choices, ComboTreeBox uses TreeItemId’s instead. If you add an item to the ComboTreeBox (using Append or Insert), the TreeItemId associated with the added item is returned. You can then use that TreeItemId to add items as children of that first item. For example:

from wx.lib.combotreebox import ComboTreeBox
combo = ComboTreeBox(parent)
item1 = combo.Append('Item 1') # Add a root item
item1a = combo.Append('Item 1a', parent=item1) # Add a child to item1

You can also add client data to each of the items like this:

item1 = combo.Append('Item 1', clientData=somePythonObject)
item1a = combo.Append('Item 1a', parent=item1,
                       clientData=someOtherPythonObject)

And later fetch the client data like this:

somePythonObject = combo.GetClientData(item1)

To get the client data of the currently selected item (if any):

currentItem = combo.GetSelection()
if currentItem:
    somePythonObject = combo.GetClientData(currentItem)

Supported styles are the same as for ComboBox, i.e. CB_READONLY and CB_SORT . Provide them as usual:

combo = ComboTreeBox(parent, style=wx.CB_READONLY|wx.CB_SORT)

Supported platforms: wxMSW and wxMAC natively, wxGTK by means of a workaround.
