PyQt5 QSpinBox – 如何通过字体获取省略的文本
在本文中,我们将看到如何获得旋转框的省略文本。如果字符串文本比宽度宽,则字符串的省略版本将是其中包含“...”的字符串。否则,将显示原始字符串。
有三个模式参数来获取省略的文本。 mode 参数指定文本是否在左侧(例如,“…tech”)、中间(例如,“Tr…ch”)或右侧(例如,“Trol…”)被省略。
为了做到这一点,我们将elidedText
方法与微调框的 QFontMetrics 对象一起使用。
Syntax : font_metrics.elidedText(text, Qt.ElideRight, 80)
Argument : It takes 3 argument, first is the spin box text, second is the elide mode and third is the width in pixel.
Return : It returns None
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(0, 999999)
# setting prefix to spin
self.spin.setPrefix("PREFIX ")
# setting suffix to spin
self.spin.setSuffix(" SUFFIX")
# 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()
# text
text = self.spin.text()
# getting elided text
elided_text = f_metrics.elidedText(text, Qt.ElideRight, 80)
# setting text to the label
label.setText("Elided Text : " + str(elided_text))
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
