PyQt5 QSpinbox – 如何从中拖动文本
在本文中,我们将看到如何拖动文本/内容,即包括前缀和后缀在内的整个文本。当我们创建一个旋转框时,我们不能从中拖动文本,拖动文本意味着根据光标将选定的文本移动到任何位置。
为此,我们将 setDragEnabled 方法与旋转框的行编辑对象一起使用。
Syntax : line_edit.setDragEnabled(True)
Argument : It takes bool as argument
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 prefix to spin
self.spin.setPrefix("Prefix ")
# setting suffix to spin
self.spin.setSuffix(" Suffix")
# getting the line edit object
line = self.spin.lineEdit()
# enabling the drag
line.setDragEnabled(True)
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
