PyQt5 QSpinBox – 获取输入法提示
在本文中,我们将了解如何获取旋转框的输入法提示。输入法提示用于检索输入法应如何操作的提示。例如,如果设置了 Qt.ImhFormattedNumbersOnly 标志,则输入法可能会更改其可视组件以反映只能输入数字。
为了做到这一点,我们将inputMethodHints
方法与旋转框对象一起使用。
Syntax : spin_box.inputMethodHints()
Argument : It takes no argument
Return : It returns method hint flag
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")
# creating a label
label = QLabel(self)
# making the label multi line
label.setWordWrap(True)
# setting geometry to the label
label.setGeometry(100, 200, 200, 60)
# getting input method hint
value = self.spin.inputMethodHints()
# setting text to the label
label.setText(str(value))
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
