I am using Qt Creator 2.0.1 based on Qt 4.7.0 (32bit). I am new to Qt.
I created a mainwindow. How do I go to another window when I press the pushbutton in the main window?
I am able to do it well. I just give the code for anyone who need this. I have a window called MainWindow
and a NewWindow
. I have a button in Mainwindow
called mMyButton
. mainwindow.h
is as follows.
#ifndef MAINWINDOW_H
#define MAINWINDOW_H
#include <QMainWindow>
//added
#include"newwindow.h"
namespace Ui {
class MainWindow;
}
class MainWindow : public QMainWindow
{
Q_OBJECT
public:
explicit MainWindow(QWidget *parent = 0);
~MainWindow();
//added
public slots:
void openNewWindow();
//added name of the new window is NewWindow
private:
NewWindow *mMyNewWindow;
private:
Ui::MainWindow *ui;
private slots:
void on_mMyButton_clicked();
};
#endif // MAINWINDOW_H
My newwindow.h is as follows.
#ifndef NEWWINDOW_H
#define NEWWINDOW_H
#include <QMainWindow>
namespace Ui {
class NewWindow;
}
class NewWindow : public QMainWindow
{
Q_OBJECT
public:
explicit NewWindow(QWidget *parent = 0);
~NewWindow();
private:
Ui::NewWindow *ui;
};
#endif // NEWWINDOW_H
My mainwindow.cpp is as follows.
#include "mainwindow.h"
#include "ui_mainwindow.h"
MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
//Added
connect(ui->mMyButton, SIGNAL(click()), this, SLOT(openNewWindow()));
}
MainWindow::~MainWindow()
{
delete ui;
}
void MainWindow::openNewWindow()
{
mMyNewWindow = new NewWindow();
mMyNewWindow->show();
}
void MainWindow::on_mMyButton_clicked()
{
openNewWindow();
}
My newwindow.cpp,
#include "newwindow.h"
#include "ui_newwindow.h"
NewWindow::NewWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::NewWindow)
{
ui->setupUi(this);
}
NewWindow::~NewWindow()
{
delete ui;
}
My main.cpp as,
#include <QtGui/QApplication>
#include "mainwindow.h"
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
MainWindow w;
w.show();
return a.exec();
}
Thanks for all the information. And enjoy the programming with Qt.
