Important

This page is under construction. It may contain wrong information and must be confirmed/repaired by Marc.

You must setup the debugger and start the project to debug it. Only then the breakpoints are useful.

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. 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.

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

Not implemented yet: Normally a breakpoint stops the program. Eventually other actions will be implemented, like enabling other breakpoints or groups.

Pass Count

How many times the enabled breakpoint has been reached.

Group

Not implemented yet: Eventually you can group breakpoints. This allows to quickly enabled/disable several breakpoints at once.
