PyQt5 QSpinBox – 设置/改变几何图形

在这篇文章中，我们将看到如何为旋转盒设置几何图形。几何图形基本上是指旋转盒的位置和大小。为旋转盒设置几何图形可以改变其大小和位置。

为了做到这一点，我们使用旋转盒对象的setGeometry方法。

语法： font_metrics.setGeometry(left, top, width, height)

参数： 它需要四个整数作为参数

返回： 它返回无

下面是实现

class Window(QMainWindow):

    def __init__(self):

        # setting title
        self.setWindowTitle("Python ")

        # setting geometry
        self.setGeometry(100, 100, 600, 400)

        # calling method

        self.show()

        # setting range to the spin box
        self.spin.setRange(1, 999999)

        # setting prefix to spin
        self.spin.setPrefix("PREFIX ")

        # setting suffix to spin
        self.spin.setSuffix(" SUFFIX")

        # creating a push button
        push = QPushButton("Press ", self)

        # setting position
        push.move(200, 300)

        # adding action to the push button
        push.clicked.connect(self.do_action)

        # left
        self.left = 20

        # top
        self.top = 20

    def do_action(self):

        # setting geometry to the spin box
        self.spin.setGeometry(self.left, self.top, 200, 40)

        # changing position
        self.left += 10
        self.top += 10



# create pyqt5 app
App = QApplication(sys.argv)

# create the instance of our Window
window = Window()

# start the app
sys.exit(App.exec())
