Struct qt_widgets::QLayout

#[repr(C)]
pub struct QLayout { /* fields omitted */ }

The QLayout class is the base class of geometry managers.

C++ class: QLayout.

C++ documentation:

The QLayout class is the base class of geometry managers.

This is an abstract base class inherited by the concrete classes QBoxLayout, QGridLayout, QFormLayout, and QStackedLayout.

For users of QLayout subclasses or of QMainWindow there is seldom any need to use the basic functions provided by QLayout, such as setSizeConstraint() or setMenuBar(). See Layout Management for more information.

To make your own layout manager, implement the functions addItem(), sizeHint(), setGeometry(), itemAt() and takeAt(). You should also implement minimumSize() to ensure your layout isn't resized to zero size if there is too little space. To support children whose heights depend on their widths, implement hasHeightForWidth() and heightForWidth(). See the Border Layout and Flow Layout examples for more information about implementing custom layout managers.

Geometry management stops when the layout manager is deleted.

Methods

impl QLayout

pub unsafe fn activate(&mut self) -> bool

Redoes the layout for parentWidget() if necessary.

Calls C++ function: bool QLayout::activate().

C++ documentation:

Redoes the layout for parentWidget() if necessary.

You should generally not need to call this because it is automatically called at the most appropriate times. It returns true if the layout was redone.

See also update() and QWidget::updateGeometry().

pub unsafe fn add_item(&mut self, arg1: impl CastInto<MutPtr<QLayoutItem>>)

Implemented in subclasses to add an item. How it is added is specific to each subclass.

Calls C++ function: pure virtual void QLayout::addItem(QLayoutItem* arg1).

C++ documentation:

Implemented in subclasses to add an item. How it is added is specific to each subclass.

This function is not usually called in application code. To add a widget to a layout, use the addWidget() function; to add a child layout, use the addLayout() function provided by the relevant QLayout subclass.

Note: The ownership of item is transferred to the layout, and it's the layout's responsibility to delete it.

See also addWidget(), QBoxLayout::addLayout(), and QGridLayout::addLayout().

pub unsafe fn add_widget(&mut self, w: impl CastInto<MutPtr<QWidget>>)

Adds widget w to this layout in a manner specific to the layout. This function uses addItem().

Calls C++ function: void QLayout::addWidget(QWidget* w).

C++ documentation:

Adds widget w to this layout in a manner specific to the layout. This function uses addItem().

pub unsafe fn closest_acceptable_size(
    w: impl CastInto<Ptr<QWidget>>,

Returns a size that satisfies all size constraints on widget, including heightForWidth() and that is as close as possible to size.

Calls C++ function: static QSize QLayout::closestAcceptableSize(const QWidget* w, const QSize& s).

C++ documentation:

Returns a size that satisfies all size constraints on widget, including heightForWidth() and that is as close as possible to size.

pub unsafe fn contents_margins(&self) -> CppBox<QMargins>

Returns the margins used around the layout.

Calls C++ function: QMargins QLayout::contentsMargins() const.

C++ documentation:

Returns the margins used around the layout.

By default, QLayout uses the values provided by the style. On most platforms, the margin is 11 pixels in all directions.

This function was introduced in Qt 4.6.

See also setContentsMargins().

pub unsafe fn contents_rect(&self) -> CppBox<QRect>

Returns the layout's geometry() rectangle, but taking into account the contents margins.
