Adding breakpoints
Line breakpoints are set on an executable line
of a program.
- In the editor area, open the
file where you want to add the breakpoint.
- Directly to the left of the
line where you want to add the breakpoint, open the marker bar (vertical ruler)
pop-up menu and select Add
Breakpoint. You can also
double-click on the marker bar next to the source code line. A new
breakpoint marker appears on the marker bar, directly to the left of the
line where you added the breakpoint.
Also, the new breakpoint appears in the Breakpoints view list.
While the breakpoint is enabled, thread
execution suspends before that line of code is executed. The debugger selects the thread that has
suspended and displays the stack frames on that thread's stack. The line where the breakpoint was set is
highlighted in the editor in the Debug perspective.
