QtCreator debug helpers "hello world"

Question

I'm trying to get started using debug helpers in QtCreator.

But I can't even get anything simple to work.

I made this simple python file:

from dumper import *

def qdump_TestClass(d, value):
    d.putNumChild(0)
    d.putValue("hi")

Then add that file in here:

This is the C++ definition of the class:

struct TestClass {
    int x, y;
};

I have been following the steps in this other question. But that didn't work for me.

Answer 1

Use double underscores in function name:

def qdump__TestClass(d, value):
         ^^

And, correct your path according to the documentation:

~/<Qt>/Tools/QtCreator/share/qtcreator/debugger/personaltypes.py

Use your Qt folder name (or path if it's not at ~).

The path showing in that dialog box is relative to your app.

Here's a complete working example:

main.cpp

struct TestClass
{
    int x {12}, y {34};
};

int main()
{
    TestClass t;
    (void) t;
    return 0;
}

personaltypes.py

from dumper import *

def qdump__TestClass(d, value):
    d.putValue("TestClass")
    d.putNumChild(2)
    if d.isExpanded():
        with Children(d):
            d.putSubItem("x", value["x"])
            d.putSubItem("y", value["y"])
