GDB & Code::Blocks : Is it possible to add own registering classes ?

If you are on windows, switch to 7.0.2, because 7.0.1 is known to have problems.

I've been recently using C::B and Qt, hence my interest in adding types to the gdb_types.script file. After some experimenting I was able to neatly print the QString. In case anyone is interesed, I solved it using the following steps:

1. in the RegisterTypes function I added:

--- Code: ---driver.RegisterType (_T("Qt String"), _T("[^[:alnum:]_]*QString[^[:alnum:]_]*"), _T("Evaluate_QtString"), _T("Parse_QtString"))

--- End code ---

2. in the file I added the functions Evaluate_QtString and Parse_QtString like this:

--- Code: ---function Evaluate_QtString (type, a_str, start, count) {
    // determine the method of accessing the variable (if it is a reference use the
    // '.' else use the '->'.
    local oper = _T(".");
    if (type.Find(_T("*"), false) > 0)
        oper = _T("->");

    // create the output string send to the debugger
    // since it is a qstring we actually want the debugger to do the following
    // (char*) stringvar.d
    local result = _T("output /c ") + a_str + oper + _T("d.data[0]@") + a_str + oper + _T("d.size");
    return result;
}

function Parse_QtString (a_str, start) {
    return Parse_wxString (a_str, start);
}

--- End code ---

Note that I reuse the Parse_wxString. No need to reinvent the wheel. The result is quite satisfactoring  :D.

I just find some discussion about viewing the Qt string, see here:
