PyQt5 QDoubleSpinBox – 加紧
在本文中,我们将了解如何以编程方式提高 QDoubleSpinBox 的值。双旋转框可以接受十进制值作为输入,我们可以通过setValue
方法设置值,踩上去只会默认递增 1 或选择自适应十进制类型时会递增十进制。
In order to do this we will use stepUp
method with the double spin box object.
Syntax : dd_spin.stepUp()
Argument : It takes no 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, 500, 400)
# calling method
self.UiComponents()
# showing all the widgets
self.show()
# method for components
def UiComponents(self):
# creating double spin box
d_spin = QDoubleSpinBox(self)
# setting geometry to the double spin box
d_spin.setGeometry(100, 100, 150, 40)
# step type
step_type = QAbstractSpinBox.AdaptiveDecimalStepType
# adaptive step type
d_spin.setStepType(step_type)
# creating a label
label = QLabel("GeeksforGeeks", self)
# setting geometry to the label
label.setGeometry(100, 200, 300, 80)
# making label multi line
label.setWordWrap(True)
# push button
push = QPushButton("Press", self)
# setting geometry to the push button
push.setGeometry(100, 150, 100, 35)
# adding action to the push button
# stepping up the value
push.clicked.connect(lambda: d_spin.stepUp())
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
