PyQt5 QSpinBox – 从中获取像素图
在这篇文章中,我们将看到如何获得被旋转盒限制的像素图。如果自旋盒有任何孩子,那么它们也会被画在适当的位置。
注意: 这个函数可以通过元对象系统和QML来调用。
为了做到这一点,我们使用旋转盒对象的 grab 方法。
语法: spin_box.grab(rectangle)
参数: 它需要QRect对象作为参数。
返回: 它返回QPixmap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(1, 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 the current geometry
geometry = self.spin.geometry()
# getting the pixmap from the spin box
pixmap = self.spin.grab(geometry)
# setting text to the label
label.setText(str(pixmap))
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出:
