By left clicking on a node in the call prefix tree you will get a window displaying the full list of tasks and the full frame label )]]>. This window also contains buttons that allow for the manipulation of the graph from that node. Right clicking on a node provides a pop-up menu with the same options. Note all of these operations are performed on the current visible state of the call prefix tree. ]]> The node operations are defined as follows: Advanced Display the full node and edge attributes. Join Equivalence Class collapses all of the descendent nodes with the same equivalence class into the current node and renders in a new tab. Collapse hide all of the descendents of the selected node. Collapse Depth collapse the entire tree to the depth of the selected node. Hide the same as Collapse, but also hides the selected node. Expand show (unhide) the immediate children of the selected node. Expand All show (unhide) all descendents of the selected node. Focus hide all nodes that are neither ancestors nor descendents of the selected node. (Note: This will not unhide any hidden ancestors.) View Source creates a popup window )]]> displaying the source file (only for stack traces with line number information). This may require the source file's path to be added to the search path, through File -> Add Search Paths. Translate For traces with module and offset granularity, this button will translate all node labels into source file and line number information and open the resulting graph in a new tab. Temporally Order Children (prototype only) determine the temporal order of the node's children (only for stack traces with line number information). Requires the source file's path and all include paths to be added to the search path, through File -> Add Search Paths. OK closes the pop-up window. ]]>
