pyqt5对用qt designer设计的窗体实现弹出子窗口的示例
1.用qtdesigner编写主窗体，窗体类型是MainWindow，空白窗口上一个按钮。并转换成mainWindow.py
#-*-coding:utf-8-*-
#Formimplementationgeneratedfromreadinguifile'f.ui'
#
#Createdby:PyQt5UIcodegenerator5.9
#
#WARNING!Allchangesmadeinthisfilewillbelost!
fromPyQt5importQtCore,QtGui,QtWidgets
classUi_MainWindow(object):
defsetupUi(self,MainWindow):
MainWindow.setObjectName("MainWindow")
MainWindow.resize(800,600)
self.centralwidget=QtWidgets.QWidget(MainWindow)
self.centralwidget.setObjectName("centralwidget")
self.pushButton=QtWidgets.QPushButton(self.centralwidget)
self.pushButton.setGeometry(QtCore.QRect(80,90,75,23))
self.pushButton.setObjectName("pushButton")
MainWindow.setCentralWidget(self.centralwidget)
self.retranslateUi(MainWindow)
QtCore.QMetaObject.connectSlotsByName(MainWindow)
defretranslateUi(self,MainWindow):
_translate=QtCore.QCoreApplication.translate
MainWindow.setWindowTitle(_translate("MainWindow","MainWindow"))
self.pushButton.setText(_translate("MainWindow","PushButton"))
2.用qtdesigner编写子窗体，窗体类型是Dialog,空白窗口上一个按钮。并转换成childWindow.py
fromPyQt5importQtCore,QtGui,QtWidgets
classUi_Dialog(object):
defsetupUi(self,Dialog):
Dialog.setObjectName("Dialog")
Dialog.resize(400,300)
self.pushButton=QtWidgets.QPushButton(Dialog)
self.pushButton.setGeometry(QtCore.QRect(160,100,75,23))
self.pushButton.setObjectName("pushButton")
Dialog.setWindowFlags(QtCore.Qt.WindowStaysOnTopHint)#设置窗体总显示在最上面
self.retranslateUi(Dialog)
QtCore.QMetaObject.connectSlotsByName(Dialog)
defretranslateUi(self,Dialog):
_translate=QtCore.QCoreApplication.translate
Dialog.setWindowTitle(_translate("Dialog","Dialog"))
self.pushButton.setText(_translate("Dialog","PushButton"))
3，编写调用程序，这个重点，
importsys fromPyQt5.QtWidgetsimportQApplication,QMainWindow,QDialog fromdust.mainWindowimport* fromdust.childWindowimport* if__name__=='__main__': app=QApplication(sys.argv) #实例化主窗口 main=QMainWindow() main_ui=Ui_MainWindow() main_ui.setupUi(main) #实例化子窗口 child=QDialog() child_ui=Ui_Dialog() child_ui.setupUi(child) #按钮绑定事件 btn=main_ui.pushButton btn.clicked.connect(child.show) #显示 main.show() sys.exit(app.exec_())
4.上面的程序只是能显示了，要想添加自定义事件，还不行，加自定义事件，有一个办法是再封装一个类，主窗体和子窗体都如此。
importsys
fromPyQt5.QtWidgetsimportQApplication,QMainWindow,QDialog
fromdust.mainWindowimport*
fromdust.childWindowimport*
#mainWindow
classMyMainWindow(QMainWindow,Ui_MainWindow):
def__init__(self):
super(MyMainWindow,self).__init__()
self.setupUi(self)
self.setGeometry(0,0,1024,600)
self.setWindowTitle('mainwindow')
defpaintEvent(self,event):
painter=QPainter(self)
pixmap=QPixmap("./image/bg.jpg")
painter.drawPixmap(self.rect(),pixmap)
defkeyPressEvent(self,e):
ife.key()==Qt.Key_Escape:
self.close()
classChildWindow(QDialog,Ui_Dialog):
def__init__(self):
super(ChildWindow,self).__init__()
self.setupUi(self)
self.setWindowTitle('childwindow')
self.pushButton.clicked.connect(self.btnClick)#按钮事件绑定
defbtnClick(self):#子窗体自定义事件
self.close()
if__name__=='__main__':
app=QApplication(sys.argv)
main=MyMainWindow()
child=ChildWindow()
btn=main.pushButton#主窗体按钮事件绑定
btn.clicked.connect(child.show)
main.show()
sys.exit(app.exec_())
