ShowCallTreepublic class ShowCallTree extends Object implements com.togethersoft.openapi.ide.IdeStartup, com.togethersoft.openapi.ide.IdeScript| This sample script shows the call tree of the selected operation.
The list of method calls done within selected operation is displayed as a
treeview in the separate tab of the bottom pane. Each call to a method is
represented with a node. Each call to a method with availale source file
is displayed as an expandable node, if there are calls made from this method.
Selecting a line with such method also positions text editor to it.
The treeview is implemented as JTree with redefined cell renderer component. |
