The window graph displays the current window and all its subwindows. The generic facilities available to all graphs throughout the LispWorks IDE are available here; see Manipulating Graphs for details.
When you first create a Window Browser, it automatically browses the parent window of the whole environment. A graph of the parent window together with its children--each individual window that has been created--is drawn in the main area.
Select any item in the graph to display its description in the Description: area.
To see the children of an unexpanded node in the graph, click on the unfilled circle to its right. To make one of the child windows be the root of the graph, select it and choose Windows > Browse - Window .
Any items selected in the graph can be operated on using commands in the Windows menu. If no items are selected, the commands in this menu apply to the root window of the graph. See Performing operations on windows for details.
