QML 自定义日期组件



  • Qt 有控件QDateEdit,但是qml没有,今天我们来自己实现一个,非常简单哦

    创建默认qml工程

    创建自定义组件 QmlDateEdit.qml

    点击上下键,计算一下日期

    import QtQuick 2.0
    
    Rectangle {
        id: rect
        width: 150
        height: 30
        border.width: 1
        border.color: "gray"
    
        property var currentDate: new Date
    
        Component.onCompleted: {
            label.text = getFormat(currentDate)
        }
    
        function up(){
            var time = currentDate.getTime() + 1*24*60*60*1000
            currentDate.setTime(time)
            label.text = getFormat(currentDate)
        }
    
        function down(){
            var time = currentDate.getTime() - 1*24*60*60*1000
            currentDate.setTime(time)
            label.text = getFormat(currentDate)
        }
    
        function addZero(value){
            if(value<10){
                return '0' + value
            }
            else{
                return value
            }
        }
    
        function getFormat(date){
            var year = date.getFullYear()
            var month = date.getMonth()
            var day = date.getDate()
    
            return year + '/' + addZero(month+1) + '/' + addZero(day)
        }
    
        TextInput{
            id: label
            anchors.verticalCenter: parent.verticalCenter
            width: parent.width-imgUp.width
            readOnly: true
            selectByMouse: true
    
        }
        Image {
            id: imgUp
            source: "qrc:/up.png"
            anchors.right: parent.right
    
            MouseArea{
                anchors.fill: parent
                onClicked: up()
            }
        }
        Image {
            id: imgDown
            source: "qrc:/down.png"
            anchors.right: parent.right
            anchors.bottom: parent.bottom
    
            MouseArea{
                anchors.fill: parent
                onClicked: down()
            }
        }
    }
    
    

    main.qml调用组件

    import QtQuick 2.9
    import QtQuick.Window 2.2
    
    Window {
        visible: true
        width: 640
        height: 480
        title: qsTr("QML 自定义日期组件")
    
        QmlDateEdit{
            id: dateEdit
        }
    }
    
    

    效果

  • 设计模式-工厂模式

    使用qt/qml来演示设计模式效果,便于学习理解

    1)定义创建对象的接口,封装对象的创建
    2)使具体化类的工作延迟到工厂子类中

    image.png

    1. 工厂类

    createProduct使用了参数来选择要创建哪个产品

    #ifndef FACTORY_H #define FACTORY_H #include <QObject> class Product; class QString; class Factory: public QObject { Q_OBJECT public: virtual ~Factory() = 0; virtual Product* createProduct(QString type) = 0; protected: Factory(); }; class ConcreteFactory: public Factory { Q_OBJECT public: ~ConcreteFactory(); ConcreteFactory(); public slots: Product* createProduct(QString type); }; #endif // FACTORY_H #include "factory.h" #include "product.h" #include <QtQml/qqml.h> Factory::~Factory() { } Factory::Factory() { qmlRegisterType<Product>("Product", 1, 0, "Product"); } ConcreteFactory::~ConcreteFactory() { } ConcreteFactory::ConcreteFactory() { } Product *ConcreteFactory::createProduct(QString type) { if(type == "boy") return static_cast<Product *>(new ConcreteProduct1()); else if(type == "girl") return static_cast<Product *>(new ConcreteProduct2()); return static_cast<Product *>(new ConcreteProduct1()); } 2 产品类

    一个产品是萌梦男,一个产品是萌梦女

    #ifndef PRODUCT_H #define PRODUCT_H #include <QObject> class Product: public QObject { Q_OBJECT public: virtual ~Product() = 0; Q_PROPERTY(QString icon READ icon NOTIFY iconChanged) QString m_icon; QString icon() const { return m_icon; } signals: void iconChanged(QString icon); protected: Product(); signals: public slots: }; class ConcreteProduct1: public Product { Q_OBJECT public: ~ConcreteProduct1(); ConcreteProduct1(); }; class ConcreteProduct2: public Product { Q_OBJECT public: ~ConcreteProduct2(); ConcreteProduct2(); }; #endif // PRODUCT_H #include "product.h" Product::~Product() { } Product::Product() { } ConcreteProduct1::~ConcreteProduct1() { } ConcreteProduct1::ConcreteProduct1() { m_icon = "qrc:/images/boy.png"; } ConcreteProduct2::~ConcreteProduct2() { } ConcreteProduct2::ConcreteProduct2() { m_icon = "qrc:/images/girl.png"; } 3. main.qml

    使用timer,canvas,listview等实现一个自动化生产的动画效果
