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)

{
 
 

    set
