Overview

This article shows how to create QWidget-based To do List. The example uses Qt's QGroupBox, QTimeEdit, QDateEdit, and QTextEdit.

Prerequisite

Header file

#ifndef MAINWINDOW_H
#define MAINWINDOW_H
 
#include <QMainWindow>
 
namespace Ui {
class MainWindow;
}

public:
MainWindow(QWidget *parent = 0);
~MainWindow();
 
protected:
void changeEvent(QEvent *e);
 
private:

};
 
#endif // MAINWINDOW_H

Source file

#include "mainwindow.h"

MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);
}
 
MainWindow::~MainWindow()
{
delete ui;
}
 
void MainWindow::changeEvent(QEvent *e)
{
QMainWindow::changeEvent(e);
switch (e->type()) {
case QEvent::LanguageChange:
ui->retranslateUi(this);
break;
default:
break;
}
}
