QlineEdit和QCalendarWidget做的简单日历

最近项目的需要，需要做一个日历。于是找资料，原来Qt中已经封装好了一个类QCalendarWidget，专门做日历的。于是我用QlineEdit加QFontComboBox。做了一个简易的日历

一下是代码

// "line_edit.h"

#include <QLineEdit>

#include <QMouseEvent>

class line_edit : public QLineEdit

{

    Q_OBJECT

public:

    explicit line_edit(QWidget *parent = 0);

    virtual void mousePressEvent(QMouseEvent *event);

    //void mouseReleaseEvent(QMouseEvent *event);

signals:

    //自定义clicked()信号,在mousePressEvent事件发生时触发

    void clicked();

};

//line_edit.cpp

#include "line_edit.h"

line_edit::line_edit(QWidget *parent):

    QLineEdit(parent)

{

    setFixedSize(100,20);

}

void line_edit::mousePressEvent(QMouseEvent *event)

{

    //如果单击了就触发clicked信号

    if (event->button() == Qt::LeftButton)

    {

        //触发clicked信号

       emit clicked();

    }

    //将该事件传给父类处理

    QLineEdit::mousePressEvent(event);

}

//"mainwindow.h"

#include <QMainWindow>

#include <QCalendarWidget>

#include "line_edit.h"

#include <QFontComboBox>

class MainWindow : public QMainWindow

{

    Q_OBJECT

public:

    explicit MainWindow(QWidget *parent = 0);

    ~MainWindow();

    QCalendarWidget *caledar;

    line_edit *lineedit;

    QFontComboBox *hms;

    QString str;

public slots:

    void ok();

};

//mainwindow.cpp

#include "mainwindow.h"

#include "ui_mainwindow.h"

#include <QDate>

#include <QDebug>

MainWindow::MainWindow(QWidget *parent) :

    QMainWindow(parent)

{

    setFixedSize(500,400);

    caledar = new QCalendarWidget(this);

    lineedit = new line_edit(this);

    hms = new QFontComboBox(this);

    lineedit->setGeometry(100,70,150,30);

    caledar->setGeometry(100,100,200,200);

    hms->clear();

    hms->insertItem(0,"00:00");

    hms->insertItem(1,"00:30");

    hms->insertItem(2,"01:00");

    hms->insertItem(3,"01:30");

    hms->setGeometry(200,70,70,20);

    caledar->hide();

    connect(lineedit,SIGNAL(clicked()),caledar,SLOT(show()));

    connect(lineedit,SIGNAL(textChanged(QString)),caledar,SLOT(show()));

    connect(caledar,SIGNAL(clicked(QDate)),this,SLOT(ok()));

}

MainWindow::~MainWindow()

{

}

void MainWindow::ok()

{

    QDate date = caledar->selectedDate();

    qDebug()<<date.year()<<date.month()<<date.day();

    int y = date.year();

    int m = date.month();

    int d = date.day();

    QString str_total;

    str_total = QString::number(y)+"-"+QString::number(m)+"-"+QString::number(d)+" ";

    lineedit->setText(str_total);

    caledar->hide();

}

//main.cpp

#include "mainwindow.h"

#include <QApplication>

int main(int argc, char *argv[])

{

    QApplication a(argc, argv);

    MainWindow w;

    w.show();

    return a.exec();

}
