PyQt5 QSpinBox – 访问光标
在这篇文章中,我们将看到如何获得旋转盒的光标,光标是一个用于显示当前位置的指示器,用于在计算机显示器或其他显示设备上与用户交互,它将响应来自文本输入或指向设备的输入。我们使用setCursor方法来为其设置新的光标。
为了做到这一点,我们使用游标方法
语法: spin_box.cursor()
参数: 它不需要参数
返回: 它返回QCursor对象
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(" Suffix")
# creating a cursor
cursor = Qt.WaitCursor
# setting cursor to the spin box
self.spin.setCursor(cursor)
# creating label
label = QLabel(self)
# setting geometry to the label
label.setGeometry(100, 200, 200, 70)
# making it multi line label
label.setWordWrap(True)
# getting cursor
get_cursor = self.spin.cursor()
# setting text to the label
label.setText("Cursor : " + str(get_cursor))
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
window.spin.setFocus()
# start the app
sys.exit(App.exec())
输出:
