sys.exit(app.exec_())
导入系统
从PyQt4导入QtGui、QtCore
类myWindow(QtGui.QWidget):
def uuu init uuu(self,parent=None):
QtGui.QWidget.\uuuuu init\uuuuuu(self,parent)
#setGeometry方法用于定位控件。
#顺序:X,Y位置-控制的宽度和高度。
自我调整大小(500350)
self.center()
setWindowTitle(“Sergio的QT应用程序”)

已单击的定义(自我):
QtGui.QMessageBox.about(self),“只是顺便过来打个招呼!”,“欢迎来到本教程%s%s!”%(
self.txtLastName.text(),self.txtLastName.text())
def中心(自我):
screen=QtGui.QDesktopWidget().screenGeometry()
size=self.geometry()
self.move((screen.width()-size.width())/2,(screen.height()-size.height())/2)
app=QtGui.QApplication(sys.argv)
mainForm=myWindow()
mainForm.show()
sys.exit(app.exec_())
它说:
回溯(最近一次呼叫最后一次):文件 “C:\Users\Sergio.Tapia\Documents\NetBeansProjects\PyQTTests\src\PyQTTests.py”, 第47行,在 mainForm=myWindow()文件“C:\Users\Sergio.Tapia\Documents\NetBeansProjects\PyQTTests\src\PyQTTests.py”, 第25行,在init self.pictureA.setGeometry(128128200200)AttributeError:'QIcon' 对象没有属性“setGeometry”
如果删除setGeometry行,应用程序将启动,但图片不会显示在任何位置。谢谢你的帮助 有很多方法,例如使用
QPixmap
类。我再次鼓励您查看PyQt的可用示例。例如,examples\animation\appchooser\
,或examples\widgets\icons\
