convert Qt Designer project into C++ code - c++

Question

I converted my .ui file via uic into a header file, which, as far as I know, contains the header AND the implementation of the .ui file.
But what part of it is the header and what is the implementation?
Is there a way to seperate them properly?

Since I'm working with VS 2019 and have the "QT VS Tools" extension installed, I could also use the new "Convert Project to Qmake generated Project" tool. The problem here is, that I don't really know how it works.
I opened my .pro file from Qt Designer with the "Open Qt project file..." funciton and then used the tool mentioned above. After the process finished, I didn't see any changes or new files. Did I miss something? Do I need to do something else?
If further information is needed, I'd be happy to help.

Answer 1

Basically the minimal Qt stand-alone example is two source files, one header file, and the UI XML file:
There's the "main" Source file which contains the main function
There's a "main window" source file which contains the implementation for the main window
There's the "main window" header file
And as mentioned there's the UI XML file
The "main" source file could be very simple, all it does is create a QApplication object and the MainWindow object. It shows the main window and then enters the application event loop:
#include <QApplication>
#include "MainWindow.h"
int main(int argc, char* argv[])
{
QApplication app(argc, argv);
MainWindow window;
window.show(); // Show the main window
return app.exec(); // Run the application event loop
}
The "main window" header file start out also very simple:
#include <QMainWindow>
namespace Ui
{
class MainWindow; // This is the "main window" from the UI XML file
}
class MainWindow : public QMainWindow
{
Q_OBJECT
public:
MainWindow(QWidget* parent = nullptr);
~MainWindow();
private:
Ui::MainWindow* ui; // Pointer to the UI generated by the XML file and the uic program
};
And finally the "main window" implementation source file:
#include "MainWindow.h"
#include "ui_mainwindow.h" // This is the automatically generated header file created by uic
MainWindow::MainWindow(QWidget* parent /* = nullptr */)
: QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
}
MainWindow::~MainWindow()
{
delete ui;
}
You also need to run the uic program to generate the needed source files from the UI XML file, and then build with the source file. You also need to use the moc tool to resolve slots and signals.
All of this should really be in most tutorials you will find online.
