Oooops! :oops: I had a node and a subnode and due to some iffy cut/pasting I was registering the events to the node instead of the subnode! :lol:

I tried something like that last night but I couldn't get it to work. :-? I'll have to have another look tonight.

Usage is really simple. First, you need to register those events for your custom node:
[code] Script.RegisterEvent oCustomNode, "OnExecMenuItem", "OnExecMenuItem"
Script.RegisterEvent oCustomNode, "OnShowMenuItem", "OnShowMenuItem"
[/code]

Then you should enable the Remove option in the context menu for that node:
[code]Function OnShowMenuItem(iItemIndex)
Select Case iItemIndex
Case 5
OnShowMenuItem = True
Case Else
OnShowMenuItem = False
End Select
End Function
[/code]

Then you should provide a code for removing that node when user click on the Remove option:
[code]Function OnExecMenuItem(iItemIndex)
If iItemIndex = 5 Then
If Not SDB.MainTree.CurrentNode Is Nothing Then
' My own function for removing node:
DeleteNodeWithMask SDB.MainTree.CurrentNode.CustomNodeID
' It could contain just:
' SDB.MainTree.RemoveNode SDB.MainTree.CurrentNode
End If
OnExecMenuItem = True
Else
OnExecMenuItem = False
End If
End Function
[/code]

Ok thanks, I'll go with that approach then. Would still be nice to understand how it's supposed to work though! :)

Yes, I tried it long time ago with Magic Nodes. If you take a look at its source code, you would find those lines commented. Those events work fine, but I dropped that idea because it wouldn't be consistent with the built-in Remove option which removes tracks from tracklist, not a node itself. For example, if you right-click on some album from the Album node and if you choose Remove option, it will remove tracks, not node. So, I added new Delete Magic Node option to the context menu and implemented my own code for removing MN nodes.

I tried to figure out how they worked a couple of years ago but with no success. Perhaps it's easiest to add your own remove menu+command? Or will that result in two remove menus?

Has anyone tried using these yet? I can't seem to do anything with them. What I'm attempting to do is allow the user to right click and remove a node which has been added by my script. Anyone got any ideas?

The wiki says one of the values of ItemIndex is "4 .. Custom Remove - Does this tree node has its own handling of Remove command?" but how do you make the tree node handle the remove command?
