All expressions in scope are displayed with the expression in -blue, the expression type in red, and the expression value in black. When an -expression value changes, it is displayed in green. Expressions that are not -in scope are all gray.</P> - - -<H3>Adding Watch Expressions</H3> -<p>To add an expression to the Watch Window, simply enter -the expression into the entry at the bottom of the window and press return -or click the "Add Watch" button. The expression is validated and added to the -Watch Window Display.</p> - -<P>To add an expression to the Watch Window from the -<A HREF="source.html">Source Window</A>, use the -"<A HREF="source.html#add_to_watch">Add to Watch</A>" option of the -<A HREF="source.html#display_popup">Source Window Pop-up Menu</A>.</P> - -<P>Any legal expression may be added to the Watch Window, which will -evaluate each of its expressions everytime the program runs. Be cautious -adding expressions which cause assignments, such as "<CODE>i++</CODE>".</P> - -<P>Adding a register to the Watch Window can be advantages when debugging -via a slow serial line. In this case, keeping the entire Register Window open -may be inefficient. Consider adding the register to the Watch Window. Simply -enter the name of the register preceded with a dollar sign ($) into the -Entry. For example, to watch the PC register, enter "<CODE>$pc</CODE>" into -the Watch Window Entry. The program counter is added to the Display.</P> - -<P>To cast pointers, simply enter the cast into the -Watch Window Entry at the bottom of the window. Use the same syntax for the -cast that the source file uses. If the source file uses C, the a simple -cast of "<CODE>ptr</CODE>" of type "<CODE>void *</CODE>" can be cast to type -"<CODE>my_struct</CODE>" by entering "<CODE>(my_struct *) ptr</CODE>" into -the Entry.</P> - -<H3>Watch Display</H3> -<p>The Watch Window Display consists of a scrolled listbox which contains all -watch expressions, one per line. To use any of the functions of the Watch -Window, use the left mouse button to select any element from the Display.</p> - -<P>Pointers, structures, and classes appear in the display with a 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 -derefernces and embedded structure viewing.</P> - -<P>The Watch Display updates after every execution of the program and -highlights in green those expressions whose values have changed.</P> - -<P>The Watch Window will, by default, display all pointers and registers in -hexadecimal and all other expressions in decimal. To change the display -format for an expression, select the Format option from the pop-up menu.</P> - -<H3>Editing an Expression</H3> -<p>To edit an expression, either double-click the left mouse button on the expression -in the Display or select the Edit option from the popup-menu.
