Popup "Alter-ego" menus

For most of the nodes displayed in the tree you can obtain a popup "alter-ego" menu. How you do this is platform-dependent, but you will typically click with the right mouse button on the name of the node.

Here is an example of the menu you might get from a Starlink NDF file:

The top line says 'Reload' and shows the same icon that the node already has (indicating an NDF structure). If you pick this option, Treeview will reload the file as an NDF; the purpose of this is so that you can update the state of a node in the tree if the file it represents has changed since it was first reveealed. Reloading a node which represents a directory in this way will refresh it with the files in the directory at the time the reload is done.

The other lines give different icons and different kinds of nodes which it can be viewed as. An NDF can be seen as an HDS structure, or as a Starlink NDX structure, or simply as a normal plain file in the directory structure. So if you pick the bottom line on the menu, the NDF icon will disappear from the tree to be replaced by a plain icon representing a file, and you will only be able to see its size and last modified date. You can popup a menu on this node in turn and change it back into an NDF or into one of the other selections you are given.
