PyQt5 QSpinBox – 获取抓取手势
在本文中,我们将了解如何将抓取手势设置为旋转框。旋转框可以使用各种抓取手势:点击手势、点击并按住(长按)手势、平移手势、捏合手势、滑动手势和自定义手势。
为了做到这一点,我们使用带有旋转框对象的grabGesture
方法。
Syntax : font_metrics.grabGesture(Qt.TapGesture)
Argument : It takes gesture flag as 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, 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 grab gesture
self.spin.grabGesture(Qt.TapGesture)
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
