PyQt5 QSpinBox – 获取字距
在这篇文章中,我们将看到如何在旋转框的文本中获得字距。字是由单个字母组成的组,它被其他字母用空格隔开,字距将增加它们之间的空间。我们可以在setWordSpacing方法的帮助下设置字间距。
注意: 设置一个较低的字距值并不能减少字距。
为了做到这一点,我们在旋转框的QFont对象中使用wordSpacing方法。
语法: font.wordSpacing()
参数: 它不需要参数
返回: 它返回浮点数
下面是实现方法
# 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(0, 999999)
# setting prefix to spin
self.spin.setPrefix("PREFIX ")
# setting suffix to spin
self.spin.setSuffix(" one two")
# getting font of the spin box
font = self.spin.font()
# setting word spacing
font.setWordSpacing(20)
# reassigning this font to the spin box
self.spin.setFont(font)
# creating a label
label = QLabel(self)
# setting geometry to the label
label.setGeometry(100, 200, 300, 60)
# getting word spacing
check = font.wordSpacing()
# setting text to the label
label.setText("Word Spacing : " + str(check))
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出:
