PyQt5 QSpinBox - 设置输入法提示
在本文中,我们将了解如何将输入法提示设置到旋转框。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,我们使用带有旋转框对象的setInputMethodHints
方法。
Syntax : spin_box.setInputMethodHints(Qt.ImhPreferLatin)
Argument : It takes method hint 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 input method hint
self.spin.setInputMethodHints(Qt.ImhPreferLatin)
# create pyqt5 app
App = QApplication(sys.argv)
# create the instance of our Window
window = Window()
# start the app
sys.exit(App.exec())
输出 :
