PyQt5 QSpinBox – 获取深度
在这篇文章中,我们将看到如何获得旋转盒的深度,颜色深度或色彩深度,也被称为比特深度,是指用于表示单个像素的颜色的比特数,在这个旋转盒中,或者用于单个像素的每个颜色分量的比特数。
为了做到这一点,我们使用深度方法
语法: spin_box.depth()
参数: 它不需要参数
返回: 它返回整数
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")
# getting depth
depth = self.spin.depth()
# creating label
label = QLabel(self)
# setting geometry to the label
label.setGeometry(100, 200, 200, 70)
# making it multi line label
label.setWordWrap(True)
# setting text to the label
label.setText("Depth : " + str(depth))
# 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:
