PyQt5 QSpinBox – 如何重绘它
在这篇文章中,我们将看到如何重新画出旋转盒。在绘制器事件的帮助下,我们可以将旋转盒绘制成用户想要的样子,但有些时候需要重新绘制旋转盒以确保绘制器事件的动作。
为了做到这一点,我们使用旋转盒对象的repaint方法。
语法: spin_box.repaint()
参数: 它不需要参数
返回: 它返回无。
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(1, 999999)
# setting prefix to spin
self.spin.setPrefix("PREFIX ")
# setting suffix to spin
self.spin.setSuffix(" SUFFIX")
# setting background color to the spin box
self.spin.setStyleSheet("QSpinBox"
"{"
"background : lightgreen;"
"}")
# repaint the spin box
self.spin.repaint()
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出:
