How to show the mainwindow.ui

[McFaraz]

I am new to QT. I've just created a pro project and added Form Class. I designed my mainwindow.ui but how should I show that? I want to start the app with that windows? I am a mac user.

You can install "QtCreator":http://get.qt.nokia.com/qtcreator/qt-creator-mac-opensource-2.3.1.dmg and create new project with QtCreator and you'll see realisation of such application.

Here is the default defenition of MainWindow with form created by QtCreator

---

main.cpp:

@
#include <QtGui/QApplication>
#include "mainwindow.h"

int main(int argc, char *argv[])
{
QApplication a(argc, argv);
MainWindow w;
w.show();

return a.exec();

}
@

---

Header mainwinwow.h:

@
#ifndef MAINWINDOW_H
#define MAINWINDOW_H

#include <QMainWindow>

namespace Ui {
class MainWindow;
}

class MainWindow : public QMainWindow
{
Q_OBJECT

public:
explicit MainWindow(QWidget *parent = 0);
~MainWindow();

private:
Ui::MainWindow *ui;
};

#endif // MAINWINDOW_H
@

---

Source mainwindow.h:

@
#include "mainwindow.h"
#include "ui_mainwindow.h"

MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
}

MainWindow::~MainWindow()
{
delete ui;
}
@

---

and mainwindow.pro file:

QT += core gui

TARGET = MainWindow
TEMPLATE = app

SOURCES += main.cpp
mainwindow.cpp

HEADERS += mainwindow.h

FORMS += mainwindow.ui

P.S. -QT- it's QuickTime so it is Qt

I am using QTCreator, but tell me how to show my main window.ui instead of main.qml

If you are using qml, you should stay in qml, especially at the beginning.

Seems, you created a Qt Quick project (which is qml).
For starting with Qt, I suggest creating a "normal" Qt project, like
Qt-Widget-Project --> Qt-Gui_...

[McFaraz]

I am writing a compiler. It's finished. I want to create GUI. I've choose QT because it has Ubuntu output. I'm good at C++. Why should I stay at QML?

[giesbert]

Your posts states that you created something with qml. If you created a "normal" qt gui project based on a main w9indow, it would work out of the box ;-)

I changed it to the GUI widget but i don't know how to manage my objects. for example; I want to change the text box text when the button is pressed. Bot of them are created and there s function for the pushButton when pressed
