在QSpinBox小部件- PyQt4中将整数替换为字符串(带逗号的整数)

import sys
from PyQt4.QtGui import QApplication, QSpinBox, QLineEdit
from PyQt4.QtCore import Qt, SIGNAL
import locale

class MySpinBox(QSpinBox):
    def __init__(self, parent=None):
        super(MySpinBox, self).__init__(parent)
        self.setRange(0, 1000000)  # 设置范围
        self.setSingleStep(1000)  # 设置步长

class MyLineEdit(QLineEdit):
    def __init__(self, parent=None):
        super(MyLineEdit, self).__init__(parent)

app = QApplication(sys.argv)

spinBox = MySpinBox()
lineEdit = MyLineEdit()

locale.setlocale(locale.LC_ALL, '')  # 设置本地化环境

def updateLineEdit():
    value = spinBox.value()
    text = locale.format("%d", value, grouping=True)  # 将整数转换为带逗号的字符串
    lineEdit.setText(text)

app.connect(spinBox, SIGNAL("valueChanged(int)"), updateLineEdit)

spinBox.show()
lineEdit.show()

sys.exit(app.exec_())
