PySide: 简单窗体布局

演示简单的窗体布局以及通过Signal/Slot同步QSlider和QSpinBox。

演示程序使用了三个Widget(不知道应该译成组件、控件还是部件，就直接用Widget吧)：QSlider、QSpinBox和QWidget。QWidget作为程序的主窗体，并作为QSlider和QSpinbox的父容器。

import sys

app = QApplication(sys.argv)

window = QWidget()
window.setWindowTitle('Enter Your Age')

spinBox = QSpinBox()
spinBox.setRange(0, 130)

slider = QSlider(Qt.Horizontal)
slider.setRange(0, 130)

QObject.connect(spinBox, SIGNAL('valueChanged(int)'),
            slider, SLOT('setValue(int)'))
QObject.connect(slider, SIGNAL('valueChanged(int)'),
            spinBox, SLOT('setValue(int)'))
spinBox.setValue(35)

button = QPushButton('Quit')
QObject.connect(button, SIGNAL('clicked()'),
                window, SLOT('close()'))

layout = QHBoxLayout()
layout.addWidget(spinBox)
layout.addWidget(slider)
layout.addWidget(button)

window.setLayout(layout)

window.show()

sys.exit(app.exec_())
