# The Stack Window

### Overview

The Stack Window allows users to view the call stack and jump between levels of the stack. To use the Stack Window in tracepoint mode, the stack pointer must be collected. See Adding an Action in the Tracepoint Dialog for more information on collecting registers.

Stack Window topics:

- Stack Display
  - Navigating the Stack Window
  - Changing the Stack Level

### Stack Display

The Stack Display consists of a listbox which displays levels of the call stack one per line. Each line contains the level number (useful when using the Console Window) and a description of the function executing in that level. Typically, the function name and either the address of the function or the file and line number where the function is defined are displayed. The Stack Window may also be used to jump between levels of the stack.

#### Navigating the Stack Window

Navigation of the Stack Window is accomplished by clicking on the desired level with the left mouse button. The Source Window Display updates to show the selected frame. All other secondary windows, Registers, Watch, and Locals update their displays for the selected frame.

#### Changing Stack Levels

To switch frames, simply click the left mouse button on the desired frame and the debugger will switch contexts, updating all windows. The selected frame is highlighted (in gold, by default).

As an alternative, changing stack levels may be accomplished via the Frame Control Buttons on the Source Window's Toolbar. These buttons may be used to change frames one level at a time (either immediately up or immediately down) or to jump to the bottom-most stack frame. See Source Frame Control Buttons for more information.
