If you enable the TreeView’s EditLabels property, the user can edit an item label by clicking twice on the text.
There are two events associated with editing labels.
The BeginLabelEdit event occurs after the second click when the EditLabels property is set or when the EditLabel function is called. You can disallow editing with a return value of 1.
This script for BeginLabelEdit prevents changes to labels of level 2 items:
TreeViewItem tvi This.GetItem(handle, tvi) IF tvi.Level = 2 THEN RETURN 1 ELSE RETURN 0 END IF
The EndLabelEdit event occurs when the user finishes editing by pressing enter, clicking on another item, or clicking in the text entry area of another control. A script you write for the EndLabelEdit event might validate the user’s changes—for example, it could invoke a spelling checker.
For control over label editing, the BeginLabelEdit event can prohibit editing of a label, as shown above. Or you can set the EditLabels property to FALSE and call the EditLabel function when you want to allow a label to be edited.
When you call the EditLabel function, the BeginLabelEdit event occurs when editing begins and the EndLabelEdit event occurs when the user presses enter or the user clicks another item.
This code for a CommandButton puts the current item into editing mode:
long h_tvi h_tvi = tv_1.findItem(CurrentTreeItem!, 0) tv_1.EditLabel(h_tvi)
