使用UI文件



  • 1.创建UI文件 mainwindow.ui,文件内容如下
    x1-1.png

    <?xml version="1.0" encoding="UTF-8"?>
    <ui version="4.0">
     <class>MainWindow</class>
     <widget class="QMainWindow" name="MainWindow">
      <property name="geometry">
       <rect>
        <x>0</x>
        <y>0</y>
        <width>400</width>
        <height>300</height>
       </rect>
      </property>
      <property name="windowTitle">
       <string>MainWindow</string>
      </property>
      <widget class="QWidget" name="centralWidget">
       <widget class="QPushButton" name="pushButton">
        <property name="geometry">
         <rect>
          <x>110</x>
          <y>80</y>
          <width>201</width>
          <height>81</height>
         </rect>
        </property>
        <property name="text">
         <string>PushButton</string>
        </property>
       </widget>
      </widget>
      <widget class="QMenuBar" name="menuBar">
       <property name="geometry">
        <rect>
         <x>0</x>
         <y>0</y>
         <width>400</width>
         <height>20</height>
        </rect>
       </property>
      </widget>
      <widget class="QToolBar" name="mainToolBar">
       <attribute name="toolBarArea">
        <enum>TopToolBarArea</enum>
       </attribute>
       <attribute name="toolBarBreak">
        <bool>false</bool>
       </attribute>
      </widget>
      <widget class="QStatusBar" name="statusBar"/>
     </widget>
     <layoutdefault spacing="6" margin="11"/>
     <resources/>
     <connections/>
    </ui>
    

    2.在命令行把ui文件转换为py文件

    pyside2-uic mainwindow.ui > ui_mainwindow.py
    

    3.注意这个py文件格式是错误的,我们需要用记事本打开,另存为UTF-8格式

    4.在main.py里导入这个文件

    from ui_mainwindow import *
    

    5.创建MainWindow类,使用Ui_MainWindow作为UI画面

    import sys
    from PySide2.QtWidgets import QApplication, QMainWindow
    from ui_mainwindow import *
    
    class MainWindow(QMainWindow):
        def __init__(self):
            super(MainWindow, self).__init__()
            self.ui = Ui_MainWindow()
            self.ui.setupUi(self)
    
    if __name__ == "__main__":
        app = QApplication(sys.argv)
    
        window = MainWindow()
        window.show()
    
        sys.exit(app.exec_())
    

    6.运行截图

  • @青山白云 对了,PySide中是pyside-uic,而且是一个单独的脚本,这点和PySide2不一样。

  • 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
