PyQt5 QSpinBox – 设置样式提示
在这篇文章中,我们将看到如何设置旋转框文本的样式提示。样式提示是由字体匹配算法使用的,以便在选定的字体家族不可用时找到一个合适的默认家族。自旋盒提供了许多样式提示,如AnyStyle、SansSerif、Times等。
为了做到这一点,我们使用自旋盒的QFont对象的setStyleHint方法。
语法: font.setStyleHint(style_hint, style_preference)
参数: 它需要样式提示作为参数,第二个参数是可选的,即偏好
返回: 它返回无
下面是实现

class Window(QMainWindow):
    def __init__(self):
        super().__init__()
        # setting title
        self.setWindowTitle("Python ")
        # setting geometry
        self.setGeometry(100, 100, 600, 400)
        # calling method
        self.UiComponents()
        # showing all the widgets
        self.show()
        # method for widgets
    def UiComponents(self):
        # creating spin box
        self.spin = QSpinBox(self)
        # setting geometry to spin box
        self.spin.setGeometry(100, 100, 250, 40)
        # setting range to the spin box
        self.spin.setRange(0, 999999)
        # setting prefix to spin
        self.spin.setPrefix("PREFIX ")
        # setting suffix to spin
        self.spin.setSuffix(" SUFFIX")
        # getting font of the spin box
        font = self.spin.font()
        # setting style Hint
        font.setStyleHint(QFont.Serif, QFont.PreferOutline)
        # reassigning this font to the spin box
        self.spin.setFont(font)
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
