The Locals Window displays all local variables in scope. It may be used to visualize local variables. Local variables need to be collected before they can be viewed. See Adding an Action in the Tracepoint Dialog for more information.
Locals Window topics:
Pointers, structures, and classes appear in the display with small exapansion box before their names. To dereference pointers or view the members of classes or structures, click the closed expansion box (which appears as a small plus sign, "+") to "expand" the listing. The expansion box changes to a minus sign, "-", indicating that the display is now open. Pointers, structures and classes may be expanded recursively to allow multiple pointer dereferences and embedded structure viewing.
The Locals Display updates as the trace buffer is navigated, highlighting in blue those variables whose values have changed.
The Locals Window will, by default, display all pointers in hexadecimal and all
other variables in decimal. To change the default display of variables, use the
"set output-radix" command in the console window. (Type "help set output-radix" in the
console window for help. To make this change permanent, it must be added to the user's
init file -- .gdbinit.) To change the display format for a variable,
select the Format option from either the Variable Menu or the
Locals Pop-up Menu.
