QVBoxLayout ¶

详细描述 ¶

此类被用于构造垂直框布局对象。见 QBoxLayout 了解细节。

最简单的类用法，像这样：

window =  QWidget()
button1 =  QPushButton("One")
button2 =  QPushButton("Two")
button3 =  QPushButton("Three")
button4 =  QPushButton("Four")
button5 =  QPushButton("Five")
layout =  QVBoxLayout()
layout.addWidget(button1)
layout.addWidget(button2)
layout.addWidget(button3)
layout.addWidget(button4)
layout.addWidget(button5)
window.setLayout(layout)
window.show()
											

First, we create the widgets we want in the layout. Then, we create the QVBoxLayout object and add the widgets into the layout. Finally, we call setLayout() to install the QVBoxLayout object onto the widget. At that point, the widgets in the layout are reparented to have window 作为它们的父级。
