Automatically dereference pointers in watch window

(1/2) > >>

wtherapy:
Please, implement the watch window as it is implemented in all the other debuggers, WinDbg, KDbg, Visual Studio: when you have a pointer, display it's value with a + sign in the left, then the user expands and sees the data referenced by the pointer. In the current implementation I need to separately dereference the pointer, thereby adding a lot of entries in the watch window.

I've made a patch, actually it simply removes the old watch, when it is dereferenced.

Hello,

that's good news, how can I use it now? Because I have build 4503 and still the same display.

XayC:
I'm still working on it, trying to implement what you actually requested. I didn't put that patch in the patch-manager (because it's a pretty trivial change), so it's not going to be merged in the svn trunk.
If you want to try that patch you have to apply it on a local copy of CB sources and compile them. And there's also another problem, if you try to dereference a pointer which is either in the Local Variables or in the Function Arguments, the item would be removed.

Regards, XayC
