PyQt5 QSpinBox – 获得三振出局位置
在本文中,我们将看到如何获得旋转框文本的删除线位置。删除线位置是从基线到应绘制删除线的位置的距离。删除线是文字的印刷表示,其中一条水平线穿过它们的中心,从而产生这样的文本。与经过审查或净化的文本相反,这些文字仍然可读。此演示文稿表示两种含义之一。
为了做到这一点,我们使用带有旋转框的 QFontMetrics 对象的strikeOutPos
方法。
Syntax : font_metrics.strikeOutPos()
Argument : It takes no argument
Return : It returns integer.
下面是实现
# importing libraries
from PyQt5.QtWidgets import *
from PyQt5 import QtCore, QtGui
from PyQt5.QtGui import *
from PyQt5.QtCore import *
import sys
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(1, 999999)
# setting prefix to spin
self.spin.setPrefix("PREFIX ")
# setting suffix to spin
self.spin.setSuffix(" SUFFIX")
# setting strike out to the font
font = self.spin.font()
font.setStrikeOut(True)
self.spin.setFont(font)
# creating a label
label = QLabel(self)
# making label multi line
label.setWordWrap(True)
# setting geometry to the label
label.setGeometry(100, 200, 300, 60)
# getting font metrics
f_metrics = self.spin.fontMetrics()
# getting the strike out position
value = f_metrics.strikeOutPos()
# setting text to the label
label.setText("Strike out position : " + str(value))
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
