Python学习笔记：PYQT5 天气信息

天气信息由天气网抓取在子程序 def Refrsh_weatherData(city)中

url = 'http://t.weather.sojson.com/api/weather/city/' + city_code[city]
res = requests.get(url).json()

建立了6个子窗口类显示当前几日的天气情况，窗口内建立槽函数，当切换城市时自动更新各窗口内的数据 

class ForeCast(QWidget):
    data_signal = pyqtSignal(object, object, object, object)
    def __init__(self, num, temp_data):
        self.num = num
        self.temp_data = temp_data
        super(ForeCast, self).__init__()

建立1个子窗口类显示当天的天气情况并显示十五天内的天气曲线，同样包含槽函数，切换城市时自动更新各窗口内的数据

class MainForeCast(QWidget):
    data_signal = pyqtSignal(object,object,object,object)
    def __init__(self, temp_data, current_data, temp_h, temp_l):
        self.temp_data = temp_data
        self.current_data = current_data
        self.temp_h = temp_h
        self.temp_l = temp_l
        super(MainForeCast, self).__init__()

主程序中实例化子窗口类并完成布局

class MainWindow(QMainWindow, Ui_MainWindow):
    def __init__(self, parent=None):
        super(MainWindow, self).__init__(parent)

        self.setWindowTitle("天气")
        # self.status.showMessage('状态提示栏',5000)
        self.setWindowIcon(QIcon('./icon/n1.ico'))

        self.setStyleSheet("#MainWindow{border-image:url(background.jpeg)}")
        
        temp_data, current_data, temp_h, temp_l = Refrsh_weatherData('昆明')
        self.mainforecast = MainForeCast(temp_data, current_data, temp_h, temp_l)

        
        self.forecast1 = ForeCast(2, temp_data)
        self.forecast2 = ForeCast(3, temp_data)
        self.forecast2 = ForeCast(4, temp_data)
        self.forecast2 = ForeCast(5,temp_data)
        self.forecast3 = ForeCast(6, temp_data)
        self.forecast4 = ForeCast(7, temp_data)
        self.forecast5 = ForeCast(8, temp_data)
        self.forecast6 = ForeCast(9, temp_data)

主程序中的combobox控件完成城市的切换，切换中发送信号更各子窗口的数据并update窗口更新画面

  def combochange(self):
        text = self.mainforecast.comboBox.currentText()
        temp_data, current_data, temp_h, temp_l = Refrsh_weatherData(text)
        self.mainforecast.data_signal.emit(temp_h,temp_l,current_data,temp_data)
        self.forecast1.data_signal.emit(temp_h,temp_l,current_data,temp_data)
        self.forecast2.data_signal.emit(temp_h, temp_l, current_data, temp_data)
        self.forecast3.data_signal.emit(temp_h, temp_l, current_data, temp_data)
        self.forecast4.data_signal.emit(temp_h, temp_l, current_data, temp_data)
        self.forecast5.data_signal.emit(temp_h, temp_l, current_data, temp_data)
        self.forecast6.data_signal.emit(temp_h, temp_l, current_data, temp_data)

界面类 class Ui_MainWindow(object)采用QtDesigner

class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
        ctypes.windll.shell32.SetCurrentProcessExplicitAppUserModelID("myappid")
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(790, 539)
        self.centralwidget = QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.verticalLayout = QVBoxLayout(self.centralwidget)
        self.verticalLayout.setObjectName("verticalLayout")
        self.frame = QFrame(self.centralwidget)
        sizePolicy = QSizePolicy(QSizePolicy.Preferred, QSizePolicy.Preferred)
        sizePolicy.setHorizontalStretch(0)
        sizePolicy.setVerticalStretch(1)
        sizePolicy.setHeightForWidth(self.frame.sizePolicy().hasHeightForWidth())
        self.frame.setSizePolicy(sizePolicy)
        self.frame.setMinimumSize(QSize(300, 100))
