Python -- Gui编程 -- Qt库的使用 -- 配置资源文件

1.源文件(qtRes.py)

 import sys
 from PyQt4 import QtCore, QtGui, uic

 class MyDialog(QtGui.QDialog):
     def __init__(self):
         QtGui.QDialog.__init__(self)
         uic.loadUi('qtRes.ui', self)

 class MyWindow(QtGui.QWidget):
     def __init__(self):
         QtGui.QWidget.__init__(self)
         self.setWindowTitle('QtRes')
         self.resize(485, 300)

         self.btn = QtGui.QPushButton('Click Here')

         self.grid = QtGui.QGridLayout()
         self.grid.addWidget(self.btn)
         self.setLayout(self.grid)

         self.connect(self.btn, QtCore.SIGNAL('clicked()'), self.onBtn)

     def onBtn(self):
         mydialog = MyDialog()
         r = mydialog.exec_()
         if r:
             self.btn.setText(mydialog.txt.text())

 app = QtGui.QApplication(sys.argv)
 mywindow = MyWindow()
 mywindow.show()
 app.exec_()

2.资源文件(qtRes.ui) -- 使用QT设计师编辑，
