Treeview in-place editing problem

Delphi 6
Win XP Home


I have a Treeview and a series of Toolbuttons.

User clicks the "Add Toolbutton".  This creates a new TreeNode and sets it to Node.EditText;
The user enters random text and presses enter.  The label data is processed by the TV.OnEdited event.

So far so good.

If the user changes the node's label but does not hit ENTER, but instead clicks another node or another control, the TV.OnEdited event doesn't seem to get called.    I tried to set the OnChanging event to say

   If (Tv.IsEditing) then
     TV.Selected.EndEdit(FALSE);

but the data is still not saved.  The label itself is changed but I have to commit the changes to a record as well and that occurs in the OnEdited event.   Any ideas?

Hi there,

I just tried duplicating your problem and just couldn't.  I used a button to add a node via:

var
    TreeNode : TTreeNode;
begin
    TreeNode := TreeView1.Items.Add(nil, '');
    TreeNode.EditText;
end;

After that, the OnEditing gets hit, I entered random characters, and clicked off the window / another tree node, and my OnEdited event was hit.  Perhaps this is a bug in Delphi 6?  Do you have all the service packs installed?  The only time I didn't get an OnEdited event was when the Caption entered was the same as what it was before editing.  Perhaps you can post a small sample that doesn't work and maybe we can spot the problem?

Thanks for your help.    I'll review my OnEdited code a little better and see if I made an error in the way I stored the changes in my record.   I'll be back to this topic soon.

Well, Placed a ShowMessage at the top of my OnEdited event and it does indeed fire.  My problem is in my data storage routine, not in the component.  Points awarded for the time you spent trying to reproduce the error.
