HP UX SoftBench Software manual Using the Graph Area, Displaying New Nodes

Using SoftBench Debugger Data Graph Window

Using the Graph Area

Using the Graph Area

The Graph Area helps you understand your program by creating a visual image of the data structures in memory and controlling the information displayed.

Displaying New Nodes

You add new nodes in the Graph Area by either of the following methods:

•Entering an expression or variable in the "()" input box and choosing "Show: Data Graph ( )" or "Show: Data Graph

Indirect ( )".

•Selecting a node in the Graph Area and selecting "Follow All" or "Follow All Recursively". SoftBench Debugger displays the dereferenced pointers as new nodes, and connects them by arcs. You can select these new nodes and follow them.

"Follow All Recursively" recursively follows pointers in each new node. In order to avoid uncontrolled growth of the graph, this operation follows only pointers with the same name as the pointers in the node you originally specified. For example, if you "Follow All Recursively" on a structure that contains pointers to several large data structures, the Data Graph Window does not trace down every location pointed to by all pointers within the structure. It displays the immediate children and stops. However, suppose one of the child structures is the root of a binary tree, each node of which contains left and right pointers. Choosing "Follow All Recursively" on any tree node displays the entire tree below that node, since all nodes contain the same pointer names (left and right) as the original node.

You can access these operations by selecting the Selected ->menu button, or by clicking the right mouse button on the Graph Area to bring up a popup menu.

Using the "Node Values" Dialog Box

You can view the values of the members within a particular structure by double clicking on the node or by selecting the node and selecting "Show

Node
