Get editcontrol of customtreectrl node
Is there any way to get a reference to the editing control that corresponds to a GenericTreeItem in a CustomTreeCtrl? I have a tree that has multiple nodes corresponding to the same underlying data. So when I use a textctrl or a checkbox or a combobox to edit one item…I’d like the data being displayed in all of the other editing controls (corresponding to the data that was editing) to be updated. I can obtain references to the GenericTreeItems that need to have their editing controls updated (via model listeners), but I cannot figure out how to get references to the editing controls themselves. I’d rather not have to maintain an additional dictionary that maps GenericTreeItems to wx controls.
I see that there is a “GetEditControl” on the CustomTreeCtrl class itself (which doesn’t take a GenericTreeItem as a parameter)…which always returns None for me - so I’m not exactly sure what that is supposed to do.
Thanks,
Andrew
Hi Andrew,
Is there any way to get a reference to the editing control that corresponds
to a GenericTreeItem in a CustomTreeCtrl?
What about GenericTreeItem.GetWindow()?
def GetWindow(self):
"""Returns the window associated to the item."""
return self._wnd

Sorry, I think I have misunderstood your question... you mean the edit
control that appears when you use wx.TR_EDIT_LABELS as a tree style
and you start editing the item? Well, this control is created and
destroyed on the fly for the item you are actually editing: the other
items do *not* have an edit control associated because you are not
editing them. Is that what you meant? Because CustomTreeCtrl can have
also wx.TextCtrl attached as a control right to the items, it is not
very clear to me what you are trying to accomplish...

These types of controls:

Looking at the InsertItemByIndex constructor again...perhaps the wxcontrol that I am giving it is infact the "window".

I was just playing with this this morning.
GetEditControl() works, but it only return a useful value *when the line is being edited*.
So if you use it in an init method, you'll always find no value. My intention was to
try and add a validator to the text control as an alternative to the method Andrea suggested
to me (I was just playing around).
The edit control seems to have a value after EVT_TREE_BEGIN_LABEL_EDIT is fired.
Unfortunately if I bind a method to this event, I still don't seem to be able to do anything
useful. As a test, I tried to set the background color, but it wasn't reflected on the screen,
I don't know why.
Here's the code snippet, FWIW.
def __init__(self):
self.tree = app.mainFrame.comboPanel.tree
self.tree.Bind(wx.EVT_TREE_BEGIN_LABEL_EDIT, self.OnBeginEdit)
def OnBeginEdit(self,event):
ec=self.tree.GetEditControl()
ec.SetBackgroundColour('red')
this code doesn't work, but at least ec is non-null.
HTH,
Danny

oops. I was referring to TreeCtrl, not customtreectrl. Please ignore...

Yes, it is. Those controls are retrieved using:
YourItem.GetWindow()
There are also method for SetWindow, GetWindowSize etc...
