Variables

The Variables pane of the Threads&Variables tab enables you to examine the values stored in the objects of your application.

Variables pane

When a stack frame is selected in the Frames pane, the Variables pane displays all data within its scope (method parameters, local and instance variables). In this pane, you can set labels for objects, inspect objects, evaluate expressions, add variables to watches and more.

Toolbar

This toolbar appears only when the Watches pane is hidden so the configured watches are displayed in the Variables pane. Hiding/showing the Watches pane is controlled through the Watches toggle button:

  • When the button is pressed, which is its default status, the Watches pane is hidden and the toolbar is shown in the Variables pane. The focus is with the Debugger tab.

  • When the button is released, the toolbar moves to the Watches pane.
