Hello,
Here is an example project using gui\treeViewControl.
It's a reasonable starting point for anyone wishing to use treeViewControl. Most (if not all) the tree operations have been implemented - moving items around with both keyboard actions as well as drag and drop with the mouse, inserting brothers and sons, deleting, copy and pasting, and undo.
The implementation is in a form - the treeViewControl is attached to a custom control in the form. With the new GUI, of course, the code can be easily be transferred to a dialog.

PS. Zip attachment updated on 7th June. "Enter" key now terminates tree text editing

Hi Steve.

The final version of your example is really nice.
Thank you.

Hi,
Here is an update for the treeViewControl example (not the control itself). It fixes a couple of bugs.

1) multiple copy bug
2) makes all items unselected when the tree file is saved.

Hi,
Here is another update. This project has a dialog with 2 adjacent custom controls. The left one has the normal treeViewControl, the right one is a simple control which just lists the tree node texts, vertically positioned to be in line with the tree nodes.

This could be of use (as a starting point) for listing related data from another database, or for drawing links to the tree nodes.
cheers

Updated for Vip7003

There are a couple of changes required in the pfc treeviewcontrol, and ideally in vpi (but I wouldn't (and didn't) make the vpi ones). When you compile, you will find there are errors and will need to change integer to keymodifier (I used uncheckedconvert). But it's simple enough. You will have to change the file properties to allow them to be edited.
