Tree display

The main area to the left of the window displays the tree with the data nodes in it. Each node is shown on a single line, and is represented by an icon, followed by its name, followed by some brief descriptive information. Additionally, there may be a handle like this at the left of the line if this node can be opened up to see inside. In the example shown in the previous section, each icon is a little star, indicating that the nodes have been recognised as NDF structures, the names are as given, and the descriptive information gives the pixel bounds of the NDFs. These nodes do have handles, since Treeview knows how to understand the data inside them. The different types of nodes which Treeview knows about are listed in section .

Nodes with handles can be opened up to display their children. The easiest way to do this is to click on the handle itself with the mouse, though various other actions will do the trick, including double-clicking on the name, and if the node is selected (see ) pressing the return key or clicking the icon in the toolbar. Once opened, they can be closed in a similar way. The child nodes behave like their parents, and can be opened and closed in the same fashion. When a node is open the handle is rotated to look like this . Here is a what the window looks like when a couple of the nodes have been opened:
