Important
You must setup the debugger and start the project to debug it. Only then the breakpoints are useful.
Dialog
State
A breakpoint can be enabled or disabled. If it is enabled, then each time the program reaches the breakpoint, the condition is checked and if results true, the action(s) set for the breakpoint will be performed.
Filename/Address
Depending on the type of the breakpoint the following is displayed:
- Source Breakpoint
- The name of the file where the breakpoint is set.
- Address Breakpoint
- (not implemented)
- The address of the breakpoint.
- This type of breakpoint is usefull if there is no source available.
- Data Breakpoint
- (not implemented)
- The address of the variable (or memory location)
Line/Length
Depending on the type of the breakpoint the following is displayed:
- Source Breakpoint
- The linenumber where the breakpoint is set.
- If you edit the source, this position can change. For example, if you insert a line in front, the breakpoint will move. :But this has no effect the line numbers in the debugging information of the executable. It will still contain the old numbers. So, better stop debugging (i.e. stop the program) before editing.
- Address Breakpoint
- (not implemented)
- (if supported by the choosen debugger) The adress range where the execution stops
- Data Breakpoint
- (not implemented)
- The size of the variable watched
Condition
Normally a reached breakpoint performs the break action(s). When a condition is defined, this condition is evaluated. If this condition evaluates to True, the break action(s) are performed.
Action
The following actions are available: Break, Enable/Disable group(s), Log message, Evaluate expression, Ignore/Handle Exceptions. A complete description of these actions can be found on the Breakpoint properties page. Only Break is currently implemented.
Pass Count
How many times the enabled breakpoint has been reached. If a passcount is defined for this breakpoint, the debugger will perform the break action(s) when this count is reached (not implemented yet)
Group
(not implemented) The group where this breakpoint belongs to. This allows to quickly enabled/disable several breakpoints at once.
