Tree View

The first window CGNS.NAV opens when you read a CGNS file is the Tree view. This is you main view of the tree, the browsing or modification of your tree has to be performed in this view or in a sub-window created from this view.

The Tree view shows you the tree of nodes in a table-like way, you can see at the same time many informations on a complete sub-tree.


A Tree view can be a view of a sub-tree of your current view. Select the top node you want as sub-tree root, press <Control-W> and the new window appears (see [1]).


You can track with the Control view wich window you have on which node. To find back the Control view when you are in a Tree view, press <BackSpace>.



The sub-tree window is another view of the same CGNS tree. If you change something in one window, all existing windows displaying the same tree are updated.

When you Cut/Copy, the selected node uses as the root node of your buffered tree. When you Paste, the selected node can act as the parent node of the new sub-tree (using <Control-Y>) or as the brother of your new sub-tree (usinf <Control-V> (see [2]).


[1]All key bindings can be customized, the bindings we give here are the default bindings.
[2]A Cut or a Copy action puts the selected root node path into a buffer. There is a single buffer for all CGNS.NAV, so if you Cut or Copy several times only the last one is taken into account. A Copy actually copies the sub-tree starting from the path in the buffer, recursively up to the end of all branches. The root node of the resulting copy is
