User forums > Using Code::Blocks

No longer viewing wxString objects in the debug watches window

(1/1)

blinkinhek:
I have used Code::Blocks a long time, with wxWidgets, and am currently on v10.05.
I no longer seem to be able to view wxString objects in the debug Watch window (as per attached)

(hope you can see the capture image, I struggled with adding a link to the image)

Sneedd:
Had the same problem for a long time. Today I tried to solve this issue and here is my solution:

The problem actually occurs because wxWidgets (I guess since 2.9.?) is now using std::string internally. If you want more information on this, you could look into wx/stringimpl.h and search for #define wxUSE_STL_BASED_WXSTRING. It is also possible to use their own implementation, if you #define wxUSE_STL_BASED_WXSTRING 0 when building wxWidgets.

Because I do not want to switch back, I looked into the share/CodeBlocks/scripts/gdb_types.script file for another solution. I'm not sure if the following code is 100% correct, but it actually works. Just put the following functions into the script and change in the RegisterTypes function the wxString type to the new functions.


--- Code: ---function RegisterTypes(driver)
{
    // wxString
    driver.RegisterType(
        _T("wxString"),
        _T("[^[:alnum:]_]*wxString[^[:alnum:]_]*"),
        _T("Evaluate_wxString3std"),
        _T("Parse_wxString3std")
    );
    // ...
}

function Evaluate_wxString3std(type, a_str, start, count)
{
    local oper = _T(".");
    if (type.Find(_T("*"), false) > 0)
        oper = _T("->");

    return _T("print ") + a_str + oper + _T("m_impl._M_dataplus._M_p");
}

function Parse_wxString3std(a_str, start)
{
    local index = a_str.Find(_T("\""));
    if (index < 0) return _T("");
    return a_str.Mid(index, a_str.Length()-index);
}

It works only with watches not with locals or function arguments (currently using Code::Blocks 13.12). So maybe someone has an answer to the following questions:
- Could the script somehow be executed on locals and functions arguments?
- Is it possible to view the raw data or disable the script on a single variable?

Generally it is preferable to use python enabled gdb and wx pretty printer scripts. They will work in the locals.
The raw data cannot be viewed at the moment, but I have it in my ToDo, so it will be possible sometime in the future.
