# Managing conditional breakpoints

An enabling condition can be applied to line breakpoints, so that the breakpoint suspends execution of a thread in one of these cases:

- when the enabling condition is true
- when the enabling condition changes

To set a condition on a breakpoint:

1. Find the breakpoint to which an enabling condition is to be applied (in the Breakpoints view or in the editor marker bar).
2. From the breakpoint's pop-up menu, select Breakpoint Properties.... The Breakpoint properties dialog will open.
3. In the properties dialog, check the Enable Condition checkbox.
4. In the Condition field enter the expression for the breakpoint condition.
5. Do one of the following:
   - If you want the breakpoint to stop every time the condition evaluates to true, select the condition is 'true' option. The expression provided must be a boolean expression.
   - If you want the breakpoint to stop only when the result of the condition changes, select the value of condition changes option.
6. Click OK to close the dialog and commit the changes. While the breakpoint is enabled, thread execution suspends before that line of code is executed if the breakpoint condition evaluates to true.

A conditional breakpoint has a question mark overlay on the breakpoint icon.
