Why create an object within an object?

Question

Qt

I saw such a design, and something shorted out in my head. I don't understand how to do that.

#include "mydialogwindow.h"
#include "ui_mydialogwindow.h"

MyDialogWindow::MyDialogWindow(QWidget *parent) :
    QDialog(parent),
    ui(new Ui::MyDialogWindow)
{
    ui->setupUi(this);
    /*code*/ 
}

Why, inside the MyDialogWindow object, create a MyDialogWindow object?
This should give infinite recursion:ui(new Ui::MyDialogWindow)

Answer 1

Ctrl + click here, everything will become clear:
#include "ui_mydialogwindow.h"

Answer 2

layout is evaluated by code validators and the accessibility validator

Answer 3

A small minus.
And this bright gray text color on a white background just strains my eyes. In general, adaptability is not bad.
PS I did not look at the layout itself as implemented, only by running html, to check that the semantics are present.

Answer 4

Slamzil, 100%.
I saw this template where is the one, now I will find it!

Answer 5

What needs to be fixed?

Availability. In particular, the issues of contrast elements. If a designer gives you such a bug, you simply have to fix it. In particular, the state of the elements:
Do you see the difference? And she is. You and I may notice it, but the user does not.
In general, everything is sad with the focus, you can’t normally tab the page - the focus flies in an unknown direction and half the page is somewhere there. Well, blue frames - not comme il faut.

Answer 6

One thing that catches the eye (or rather, not really) is the social icons. not everyone will see networks :)
