40.12.6 Call Hierarchy View

The Call Hierarchy view presents the call tree of a function or task.

Place the editor cursor on a function or task, right-click, and choose Show > Call Hierarchy, or press Ctrl + Alt + H.

The view shows method calls in the selected function or task. You can expand nodes in the tree to further inspect the hierarchy.

Note: Conditional ( if / case) and fork blocks are also shown. You can hide them using the Filters... toolbar button.

Note: To show labeled blocks in the view use the Filters... toolbar button.

Note: When calling a virtual method on a base class handle, any of the child overrides of that method may be executed, depending on the runtime object type. In addition to the method call, you may choose to see all child overrides of the called method, using the Filters... toolbar button.

Tip: Double click on any node to jump to the method call.

Tip: Use Up and Down arrow keys to navigate the view, Left to collapse and Right to expand.

Tip: Right-click on a node to:

  • Remove from View Remove selected node from the tree.

  • Expand Children Expand all children of the selected node.

  • Expand Multiple Levels Expand a custom number of levels from the selected node.

  • Go to First Call Jump to the first call of a recurrent method call.

  • Go to Declaration Jump to the declaration of the selected method.

Link with editor Link tree selection with editor.
Filters Hide conditional, fork or override nodes. Changing filters requires refresh (see below).
