No member named _is_QWidget?

[MartinAskestad]

I am probably missing something obvious, but when I try to add a QHBoxLayout to my QMainWindow I get the error 'libqboxlayout.QHBoxLayout' has no member named '_is_QWidget' The code I've written is

var ret = try alloc.create(AppMainWindow);
ret.w = qt6.QMainWindow.New2();

const programButtons = qt6.QHBoxLayout.New2();
ret.w.SetCentralWidget(programButtons);

I've also tried

const programButtons = qt6.QHBoxLayout.New(ret.w);
ret.w.SetCentralWidget(programButtons);

Anyone know what I've missed? I've added qboxlayout to qt libs in build.zig.

Hi! Thanks for the interest!

The issue is that QMainWindow::setCentralWidget expects a parameter of type QWidget or one that inherits from it. QHBoxLayout does not inherit from QWidget which is why you are seeing that error. If you were to use an object of the type QPushButton for example, that should work just fine.
