## Detailed Description
该QBoxLayout班线达子部件水平或垂直。
QBoxLayout佔用空间它得到(从其父布局或从[parentWidget](qlayout.html#parentWidget)( ) ) ,将其划分成一排箱子,并使得每个管理部件填补一个盒子。
![Horizontal box layout with five child widgets](https://img.kancloud.cn/82/88/8288f0758cdd11f877c02dc583377c63_437x44.png)
如果QBoxLayout的方向是[Qt.Horizontal](qt.html#Orientation-enum)盒子被放置在一个行中,用合适的尺寸。每个窗口小部件(或其他框)将得到至少它的最小尺寸,并在最其最大大小。任何多馀的空间是根据拉伸系数(更多关于下文)共享。
![Vertical box layout with five child widgets](https://img.kancloud.cn/1a/f5/1af5ac720f4e8eb794a8a7693c07de14_97x193.png)
如果QBoxLayout的方向是[Qt.Vertical](qt.html#Orientation-enum)时,盒被放置在一个柱,再以合适的尺寸。
创建QBoxLayout最简单的方法是使用便利的一个类,例如[QHBoxLayout](qhboxlayout.html)(为[Qt.Horizontal](qt.html#Orientation-enum)框)或[QVBoxLayout](qvboxlayout.html)(为[Qt.Vertical](qt.html#Orientation-enum)框) 。您也可以直接使用QBoxLayout构造函数,指定其方向[LeftToRight](qboxlayout.html#Direction-enum),[RightToLeft](qboxlayout.html#Direction-enum),[TopToBottom](qboxlayout.html#Direction-enum)或[BottomToTop](qboxlayout.html#Direction-enum)。
如果QBoxLayout不是顶层布局(即它不是管理所有部件的面积和儿童) ,您必须将其添加到它的父布局之前,你可以用它做任何事情。正常的方式来添加一个布局是通过调用parentLayout - \u003e[addLayout](qboxlayout.html#addLayout)( ) 。
一旦你这样做,你可以添加盒使用四个功能之一的QBoxLayout :
* [addWidget](qboxlayout.html#addWidget)() to add a widget to the QBoxLayout and set the widget's stretch factor. (The stretch factor is along the row of boxes.)
* [addSpacing](qboxlayout.html#addSpacing)() to create an empty box; this is one of the functions you use to create nice and spacious dialogs. See below for ways to set margins.
* [addStretch](qboxlayout.html#addStretch)() to create an empty, stretchable box.
* [addLayout](qboxlayout.html#addLayout)() to add a box containing another [QLayout](qlayout.html) to the row and set that layout's stretch factor.
使用[insertWidget](qboxlayout.html#insertWidget)( )[insertSpacing](qboxlayout.html#insertSpacing)( )[insertStretch](qboxlayout.html#insertStretch)()或[insertLayout](qboxlayout.html#insertLayout)()插入一个框在布局中的指定位置。
QBoxLayout还包括两个边宽度:
* [setContentsMargins](qlayout.html#setContentsMargins)() sets the width of the outer border on each side of the widget. This is the width of the reserved space along each of the QBoxLayout's four sides.
* [setSpacing](qboxlayout.html#setSpacing)() sets the width between neighboring boxes. (You can use [addSpacing](qboxlayout.html#addSpacing)() to get more space at a particular spot.)
保证金默认是由风格提供。默认边距最的Qt样式指定为9子控件和11窗口。的间隔预设为相同的边宽为顶层布局,或以相同的父布局。
从布局中删除一个小部件,请致电[removeWidget](qlayout.html#removeWidget)( ) 。调用[QWidget.hide](qwidget.html#hide)( )上的一个小部件也有效地消除了从布局小部件,直到[QWidget.show](qwidget.html#show)()被调用。
你几乎总是要使用[QVBoxLayout](qvboxlayout.html)和[QHBoxLayout](qhboxlayout.html)而不是QBoxLayout因为他们的方便的构造函数。
