How does Run abort work

(1/4) > >>

tigerbeard:
In the CodeBlocks compiler toolbar is a red button with a white cross. If one starts the current project with the green Run button, is stopped when that red button is pressed.

Does anyone know what actually happens when I press that button?



using CB16.1/Win7

C::b is open source so: look into the code ;)


--- Code: ---int CompilerGCC::KillProcess()

I don't think this is the correct function:)

well i didn't read the title...

tigerbeard:

--- Code: ---ret = wxProcess::Kill(m_CompilerProcessList.at(i).PID, wxSIGTERM);

--- End code ---
Wouldn't that be the same than using taskkill PID on the console? This produces a different result that that button, so the button must do sth else.

Forgot to say that I tried that. Unfortunately CB does not compile so I can't use a breakpoint to find out where I need to look or what I need to search for. Unfortunatley I did not yet understand the structure of the source, though. Maybe a hint about which class handles that button would help.
