pyqt4使用簡易筆記

1、ui文件【designer產物，自行了解】直接調用

 1 # -*- coding: utf-8 -*-
 2 from PyQt4 import QtCore, QtGui,uic
 3 # qtCreatorFile =  "TestRunner.ui"
 4 Ui_MainWindow, QtBaseClass = uic.loadUiType("TestRunner.ui")
 5 
 6 class MyApp(QtGui.QTabWidget,Ui_MainWindow):
 7     def __init__(self):
 8         QtGui.QTabWidget.__init__(self)
 9         Ui_MainWindow.__init__(self)
10         self.setupUi(self)
11 
12         #接口：信號-槽
13         self.run.clicked.connect(self.slot_run)#執行XXX
14 
15 
16     def slot_run(self):
17     　　pass
18         
19 
20  if __name__ == "__main__":
21     app = QtGui.QApplication(sys.argv)
22     window = MyApp()
23     window.show()
24     sys.exit(app.exec_())

2、ui文件轉化py

一、命令：python xxx\site-packages\PyQt4\uic\pyuic.py "ui文件路徑" -o "py文件路徑"

二、直接在生成的.py文件的後面添加如下代碼

 1 #方式一、Form窗口等須要先建一個MainWindow
 2 class MainWindow(QtGui.QWidget):
 3     def __init__(self,parent=None):
 4         QtGui.QWidget.__init__(self,parent)
 5         self.ui = Ui_Form()
 6         self.ui.setupUi(self)     
 7     
 8 if __name__ == "__main__":
 9     app = QtGui.QApplication(sys.argv)
10     myapp = MainWindow()
11     myapp.show()
12     app.exec_()
13 
14 #方式二、MainWindow窗口直接這樣【其實其餘窗口也能夠，就是要先有MainWindow再有ui】
15 if __name__ == "__main__":
16     import sys
17     app = QtGui.QApplication(sys.argv)
18     MainWindow = QtGui.QMainWindow()
19     ui = Ui_MainWindow()
20     ui.setupUi(MainWindow)
21     MainWindow.show()
22     sys.exit(app.exec_())
