Question

I have MyCustomWidget in a namespace MyNameSpace

namespace MyNameSpace{
    class MyCustomWidget : public QWidget{
    };
}

How do I promote a QWidget to MyCustomWidget in my UI form? It doesn’t seem to accept a custom namespace.

Answer 1

Type the name of the class with the namespace included: My::PushButton. It works. Note that:

• Qt Designer will try and guess the header name: my_pushbutton.h. Change it if it is wrong.
• You should check the include paths in your project to determine if a global include for the promoted widget will work
