What is in an inherited constructor call?

Question

Qt

I have a constructor call
MyWindow :: MyWindow(QWidget *parent) : QDialog(parent), ui(new UI:MyWindow)
{//constructor body}
Question: What is ui(new UI:MyWindow)?
ui is an object of type MyWindow, which is declared in the MyWindow class itself. (What surprised me)
UI is a namespace.

Answer 1

MyWindow- this is your controller, which you wrote with your own hands. It asks you to use a code-generated view UI::MyWindow(another class!) that Qt wrote for you following the directions from QtDesigner's `.ui` file. How exactly to use? UI::MyWindowstored in MyWindowin the field ui.

Answer 2

This is the widget that is used in the form .ui
