标签显示两个 QSpinBox (Python + Pyside) 的总和? [英] label displays sum of two QSpinBox (Python + Pyside)?

问题描述

有人可以帮我修复代码以在总列中显示两个微调器数量+计数器"的总和.目前总标签只显示单个微调器的值.我需要它来显示两个微调器的总和.由于我是 Python 新手，因此欢迎提供任何其他修复或注释.

Could someone help me fix the code to display in the total column the sum of the two spinners 'Amount + Counter'. Currently the total label just displays the value of a single spinner. I need it to display the sum of both spinners. Any additional fixes or notes are welcome as I'm new to python.

非常感谢.

以下是固定的工作代码

#!/usr/bin/python
# -*- coding: utf-8 -*-

import sys
from PySide import QtGui, QtCore

class Example(QtGui.QWidget):

    def __init__(self):
        super(Example, self).__init__()

        self.initUI()

    def initUI(self):

        #Add all GUI Elements to Class
        self.amountLabel = QtGui.QLabel('Amount')
        self.counterLabel = QtGui.QLabel('Counter')
        self.totalLabel = QtGui.QLabel('Total')
        self.amountSpin = QtGui.QSpinBox()
        self.counterSpin = QtGui.QSpinBox()

        self.totalOutput = QtGui.QLabel('0')

        grid = QtGui.QGridLayout()
        grid.setSpacing(0)

        grid.addWidget(self.amountLabel, 3, 0)
        grid.addWidget(self.counterLabel, 3, 1)
        grid.addWidget(self.totalLabel, 3, 2)

        grid.addWidget(self.amountSpin, 4, 0)
        grid.addWidget(self.counterSpin, 4, 1)
        grid.addWidget(self.totalOutput, 4, 2)

        self.setLayout(grid)

        # ACTIONS
        self.amountSpin.valueChanged[str].connect(self.onChanged)
        self.counterSpin.valueChanged[str].connect(self.onChanged)

        self.setGeometry(800, 400, 250, 80)
        self.setWindowTitle('Simple Calculator')
        self.show()

    def onChanged(self, val):
        #we ignore the val and just get the values directly from our spinboxes
        sum = self.amountSpin.value() + self.counterSpin.value()
        #and display them
        self.totalOutput.setText(str(sum))
        self.totalOutput.adjustSize()

def main():

    app = QtGui.QApplication(sys.argv)
    ex = Example()
    sys.exit(app.exec_())


if __name__ == '__main__':
    main()

推荐答案

试试这个:

#Add all GUI Elements to Class
self.amountLabel = QtGui.QLabel('Amount')
self.counterLabel = QtGui.QLabel('Counter')
self.totalLabel = QtGui.QLabel('Total')
self.amountSpin = QtGui.QSpinBox()
self.counterSpin = QtGui.QSpinBox()

[...]

# ACTIONS
self.amountSpin.valueChanged[str].connect(self.onChanged)
self.counterSpin.valueChanged[str].connect(self.onChanged)

[...]

def onChanged(self, val):
    #we ignore the val and just get the values directly from our spinboxes
    sum = self.amountSpin.Value + self.counterSpin.Value
    #and display them
    self.totalOutput.setText(QString(sum))
    self.totalOutput.adjustSize()
