can coldblocks break program automaticly in debug when variable is changed

(1/1)

fei123:
using gdb ,we can break program when variable is changed .
we just use the cmd “watch  a” .
a =0 firstly,then when a is changed into 1,the program will be break running   automaticly.

how can i do this in codeblocks??
codeblocks can watch the change of  variable .the colour will be changed when the variable is changed . but the programme will not be break automaticly !!

thank u for your help .

Have you see the "command input control" at the bottom of the  debug panel. You can enter (do) anything as you did in GDB.

Memory may be failing me but isn't there a "Debug->Debugging windows->Watches" window for this kind of thing?

There is something called Data breakpoints.
I think, that in order to use them you need to stop on a breakpoint first.
Then right click your variable in the editor and "Add data breakpoint for 'myvar'" or something like that.

yes。it is right。
in my example just input  “watch a ”  in the debug---send user command to debug ，and  select view--Logs .
i can see the informations like "info breakpoint " in gdb
