Using the Threads Window

The Threads window displays the names and status of all the threads and thread groups in your program. For more information about this window including its context menu options, press F1 or click Help in the Threads window.

To open the Threads window:

Open source files in the Source Editor and set breakpoints.
Click Debug from the toolbar.
When the debugger stops at a breakpoint, choose View Debug Windows Threads from the main menu.

The step commands including Step Over, Step Into, and Set Next Statement apply to the current thread. To select a different thread, right-click a thread and choose Select Thread from the context menu.

When you highlight a thread in the Threads window, the Stack window is automatically updated to show the stack for the highlighted thread.
