Struct gtk4::CenterBox

source ·
#[repr(transparent)]
pub struct CenterBox { /* private fields */ }
Expand description

CenterBox arranges three children in a row, keeping the middle child centered as well as possible.

An example GtkCenterBox

To add children to CenterBox, use set_start_widget(), set_center_widget() and set_end_widget().

The sizing and positioning of children can be influenced with the align and expand properties of the children.

GtkCenterBox as GtkBuildable

The CenterBox implementation of the Buildable interface supports placing children in the 3 positions by specifying “start”, “center” or “end” as the “type” attribute of a <child> element.

CSS nodes

CenterBox uses a single CSS node with the name “box”,

The first child of the CenterBox will be allocated depending on the text direction, i.e. in left-to-right layouts it will be allocated on the left and in right-to-left layouts on the right.

In vertical orientation, the nodes of the children are arranged from top to bottom.

Accessibility

Until GTK 4.10, CenterBox used the GTK_ACCESSIBLE_ROLE_GROUP role.

Starting from GTK 4.12, CenterBox uses the GTK_ACCESSIBLE_ROLE_GENERIC role.

Properties

baseline-position

The position of the baseline aligned widget if extra space is available.

Readable | Writeable

center-widget

The widget that is placed at the center position.

Readable | Writeable

end-widget

The widget that is placed at the end position.

In vertical orientation, the end position is at the bottom. In horizontal orientation, the end position is at the trailing edge wrt. to the text direction.

Readable | Writeable

shrink-center-last

Whether to shrink the center widget after other children.

By default, when there’s no space to give all three children their natural widths, the start and end widgets start shrinking and the center child keeps natural width until they reach minimum width.

If set to FALSE, start and end widgets keep natural width and the center widget starts shrinking instead.

Readable | Writeable

start-widget

The widget that is placed at the start position.

In vertical orientation, the start position is at the top. In horizontal orientation, the start position is at the leading edge wrt. to the text direction.

Whether the widget is the default widget.

Readable

has-focus

Whether the widget has the input focus.

Readable

has-tooltip

Enables or disables the emission of the ::query-tooltip signal on @widget.

A value of true indicates that @widget can have a tooltip, in this case the widget will be queried using query-tooltip to determine whether it will provide a tooltip or not.

Readable | Writeable

The LayoutManager instance to use to compute the preferred size of the widget, and allocate its children.

This property is meant to be set by widget implementations, typically in their instance init function.

Readable | Writeable

margin-bottom

This property adds margin outside of the widget’s normal size request, the margin will be added in addition to the size from WidgetExt::set_size_request() for example.

Readable | Writeable

margin-end

Margin on end of widget, horizontally.

This property supports left-to-right and right-to-left text directions.

This property adds margin outside of the widget’s normal size request, the margin will be added in addition to the size from WidgetExt::set_size_request() for example.

Readable | Writeable

overflow

How content outside the widget’s content area is treated.

This property is meant to be set by widget implementations, typically in their instance init function.

Readable | Writeable

Also see Tooltip::set_markup().

This is a convenience property which will take care of getting the tooltip shown if the given string is not None: has-tooltip will automatically be set to true and there will be taken care of query-tooltip in the default signal handler.

Note that if both tooltip-text and tooltip-markup are set, the last one wins.
