why I do NOT have ui_myprog.h?

[Pereubu2018]

1. My QT gui program works fine but I do have ui_myprog.h anywhere. Qt 5.1.1 and Visaul studio 2017 C++…?
Am I missing something?

2. I have come across on the net. Non Modal dizajn:

MyownProg:: MyOwnProg(QWidget* parent):
QMainWindow(parent), ui(new Ui::MyownProg), _dialog(nulptr)
{

where:

…
_dialog = new Dialog(this)
-dialog->show();

….

The question is what is _dialog?
Why they did in this way? Maybe in myownprog.h to include Dialog* _dialog? Or that is same?

ui_myprog.h is a file auto generated from myprog.ui

There is no files with ui_myprogorsuch.h. I am working on Msvc 2017 C++…. That was my question with latest qt...That was my questions..

It looks like there is no plugin integrating MSVC and Qt.
You have in project the file myprog.ui (Qt Designer file). At the stage of build the project, the ui_myprog.h file should be automatically generated.
