6.11 Breakpoints

6.11.2 Setting breakpoints on lines of code

You can set breakpoints on lines of code in source code files. The application will break to the debugger when it executes that line of code, or, depending on the way the code has been compiled, as near as possible to that line.

You can set a breakpoint on a line of code in any tool that can show you it. The editor is the obvious tool to use, but you can also breakpoint lines of code that you can see in the debugger's source pane or the browser's Source page.

To set a breakpoint in any of these situations, click on the leftmost column of the line you wish to breakpoint. You can only do this for lines showing an underscore character in the leftmost column.

When you set the breakpoint, a solid red circle appears to show that it is an enabled pausing breakpoint. You can toggle the breakpoint between enabled and disabled by clicking on the circle. You can also use the shortcut (right-click) menu to manipulate breakpoints on lines of code. See Section 6.11.4.
