Detailed Description

The QBoxLayout class lines up child widgets horizontally or vertically.

\inmodule QtWidgets

QBoxLayout takes the space it gets (from its parent layout or from the parentWidget()), divides it up into a row of boxes, and makes each managed widget fill one box.

Horizontal box layout with five child widgets

If the QBoxLayout's orientation is Qt::Horizontal the boxes are placed in a row, with suitable sizes. Each widget (or other box) will get at least its minimum size and at most its maximum size. Any excess space is shared according to the stretch factors (more about that below).

Vertical box layout with five child widgets

If the QBoxLayout's orientation is Qt::Vertical, the boxes are placed in a column, again with suitable sizes.

The easiest way to create a QBoxLayout is to use one of the convenience classes, e.g. QHBoxLayout (for Qt::Horizontal boxes) or QVBoxLayout (for Qt::Vertical boxes). You can also use the QBoxLayout constructor directly, specifying its direction as LeftToRight, RightToLeft, TopToBottom, or BottomToTop.

If the QBoxLayout is not the top-level layout (i.e. it is not managing all of the widget's area and children), you must add it to its parent layout before you can do anything with it. The normal way to add a layout is by calling parentLayout->addLayout().

Once you have done this, you can add boxes to the QBoxLayout using one of four functions:

\list

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() 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() to create an empty, stretchable box.

addLayout() to add a box containing another QLayout to the row and set that layout's stretch factor. \endlist

Use insertWidget(), insertSpacing(), insertStretch() or insertLayout() to insert a box at a specified position in the layout.

QBoxLayout also includes two margin widths:

\list

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() sets the width between neighboring boxes. (You can use addSpacing() to get more space at a particular spot.) \endlist

The margin default is provided by the style. The default margin most Qt styles specify is 9 for child widgets and 11 for windows. The spacing defaults to the same as the margin width for a top-level layout, or to the same as the parent layout.

To remove a widget from a layout, call removeWidget(). Calling QWidget::hide() on a widget also effectively removes the widget from the layout until QWidget::show() is called.

You will almost always want to use QVBoxLayout and QHBoxLayout rather than QBoxLayout because of their convenient constructors.

Constructor & Destructor Documentation

◆ QBoxLayout()

QBoxLayout::QBoxLayout	(	Direction	dir,
		QWidget *	parent = `nullptr`
	)

explicit

Constructs a new QBoxLayout with direction dir and parent widget parent.

The layout is set directly as the top-level layout for parent. There can be only one top-level layout for a widget. It is returned by QWidget::layout().

See also: direction(), QWidget::setLayout()

Definition at line 556 of file qboxlayout.cpp.

◆ ~QBoxLayout()

QBoxLayout::~QBoxLayout ( )

Destroys this box layout.

The layout's widgets aren't destroyed.

Here is the call graph for this function:

◆ addSpacing()

void QBoxLayout::addSpacing ( int size )

Adds a non-stretchable space (a QSpacerItem) with size size to the end of this box layout. QBoxLayout provides default margin and spacing. This function adds additional space.

◆ addStrut()

void QBoxLayout::addStrut ( int size )

Limits the perpendicular dimension of the box (e.g. height if the box is \l LeftToRight) to a minimum of size. Other constraints may increase the limit.

See also: addItem()

Definition at line 1068 of file qboxlayout.cpp.

◆ addWidget()

void QBoxLayout::addWidget	(	QWidget *	widget,
		int	stretch = `0`,
		Qt::Alignment	alignment = `Qt::Alignment()`
	)

Adds widget to the end of this box layout, with a stretch factor of stretch and alignment alignment.

The stretch factor applies only in the \l{direction()}{direction} of the QBoxLayout, and is relative to the other boxes and widgets in this QBoxLayout. Widgets and boxes with higher stretch factors grow more.

If the stretch factor is 0 and nothing else in the QBoxLayout has a stretch factor greater than zero, the space is distributed according to the QWidget:sizePolicy() of each widget that's involved.

The alignment is specified by alignment. The default alignment is 0, which means that the widget fills the entire cell.

Reimplements QLayout::spacing(). If the spacing property is valid, that value is returned. Otherwise, a value for the spacing property is computed and returned. Since layout spacing in a widget is style dependent, if the parent is a widget, it queries the style for the (horizontal or vertical) spacing of the layout. Otherwise, the parent is a layout, and it queries the parent layout for the spacing().
