How do I update header file with .ui update?

[GriffinKnox]

How do I update the header file after saving the .ui file?

I've disabled shadow copying, and can see that it generated a ui_projectname.h file but it does not change the main header file.
What I am trying to do is import a .ui from a PyQt5 project that I've made, and want to convert to C++. I am unable to access any members such as lineEdit->setText("Hello World"); in the main.cpp after Widget w;

Any help with this would be unfathomably wonderful. I've been googling for hours, and my unfamiliarity with C++ .

"Import" in which way? At runtime or do you basically just want to re-use your .ui you've created for a PyQt project in a C++ project?

Did you include your new ui file in your *.pro file?

Do your classes include the new ui-header?

Edit:

If you want to add your former Python UI to your (existing) C++ project (create a new widget from .ui), you can use QUiLoader
https://doc.qt.io/qt-5/quiloader.html#details

// MyWidget = your new widget class that uses the ui file
MyWidget::MyWidget(QWidget *parent)
    : QWidget(parent)
{
    QUiLoader loader;
    QFile file(":/forms/myform.ui");
    file.open(QFile::ReadOnly);
    QWidget *myWidget = loader.load(&file, this);
    file.close();

    QVBoxLayout *layout = new QVBoxLayout;
    layout->addWidget(myWidget);
    setLayout(layout);
}

Hi

• Any help with this would be unfathomably wonderful. I've been googling for hours, and my unfamiliarity with C++ .

What i would do it to create a new empty UI form with .h and .cpp (and add it to the project)

And then copy the UI file over the new empty one. (creator closed )
Open Creator
Then clean all, rebuild all and it should generate the ui_xxx automatically and
in your .cpp you have access to all via UI as normal in c++.

QUiLoader also works great but no access via UI->
