Renaming items
If you enable the TreeView’s EditLabels property,
the user can edit an item label by clicking twice on the text.
Events
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:
|
1 |
TreeViewItem tvi<br>This.GetItem(handle, tvi)<br>IF tvi.Level = 2 THEN <br>   RETURN 1<br>ELSE<br>   RETURN 0<br>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.
EditLabel function
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:
|
1 |
long h_tvi<br>h_tvi = tv_1.findItem(CurrentTreeItem!, 0)<br>tv_1.EditLabel(h_tvi) |
