class video_record(QWidget): def __init__( self ): super ().__init__() self .initUI() def initUI( self ): self .startbtn = QPushButton( 'begin' , self ) self .startbtn.setGeometry( 40 , 20 , 100 , 20 ) self .startbtn.clicked.connect( self .time1) self .timeshow = QLineEdit('', self ) self .timeshow.setGeometry( 200 , 200 , 100 , 20 ) self .setGeometry( 100 , 100 , 640 , 480 ) self .setWindowTitle( 'rec' ) self .show() def time1( self ): print ( 'rec start' ) self .nw = newin() self .nw.show() self .nw.exex_() class newin(QDialog): def __init__( self ): super ().__init__() self .initUI() def initUI( self ): self .lblx = QLabel( 'hh' , self ) self .lblx.setGeometry( 100 , 100 , 100 , 20 ) self .lblx.setAutoFillBackground( True ) self .pale = QPalette() self .pale.setColor(QPalette.Window,Qt.blue) self .lblx.setPalette( self .pale) self .setGeometry( 100 , 100 , 300 , 300 ) self .setWindowTitle( 'newin' ) self .show() if __name__ = = '__main__' : app = QApplication(sys.argv) ex = video_record() ex.show() sys.exit(app.exec_()) |
如果测试时发现闪退,可以试着修改一下调用子窗口的程序:
把‘show'去掉:
1
2
3
4
5

def time1( self ): print ( 'rec start' ) self .nw = newin() #self.nw.show() self .nw.exex_() |
