The Variables view displays information about the variables associated with the stack frame that is currently selected in the Debug view.
The variables can be expanded to show their fields. The detail pane in the area at the bottom of the view displays text. For a variable of a primitive type, this is the value of the object. For a complex variable, such as a sequence, dictionary, or event, it is the text representation of the object as returned by the object's toString() method.
For complex variables, you can click the Show Logical Structure button () to expand the variables to show their sub-values.
If you want to change the layout of the display, click the drop-down menu button () at the top right of the Variables view. From the resulting menu, select Layout and then the desired layout option.
See the Eclipse online help for detailed information on this view.
