GI.Gtk.Objects.Box

The GtkBox widget arranges child widgets into a single row or column, depending upon the value of its Orientable:orientation property. Within the other dimension, all children are allocated the same size. Of course, the Widget:halign and Widget:valign properties can be used on the children to influence their allocation.

Use repeated calls to boxAppend to pack widgets into a GtkBox from start to end. Use boxRemove to remove widgets from the GtkBox. boxInsertChildAfter can be used to add a child at a particular position.

Use boxSetHomogeneous to specify whether or not all children of the GtkBox are forced to get the same amount of space.

Use boxSetSpacing to determine how much space will be minimally placed between all children in the GtkBox. Note that spacing is added between the children.

Use boxReorderChildAfter to move a child to a different place in the box.

CSS nodes

GtkBox uses a single CSS node with name box.

Accessibility

GtkBox uses the AccessibleRoleGroup role.

append

boxAppend

Arguments

:: (HasCallStack, MonadIO m, IsBox a, IsWidget b)

=> a

box: a Box

-> b

child: the Widget to append

-> m ()

Adds child as the last child to box.

getBaselinePosition

boxGetBaselinePosition

Arguments

:: (HasCallStack, MonadIO m, IsBox a)

=> a

box: a Box

-> m BaselinePosition

Returns: the baseline position

Gets the value set by boxSetBaselinePosition.

getHomogeneous

boxGetHomogeneous

Arguments

:: (HasCallStack, MonadIO m, IsBox a)

=> a

box: a Box

-> m Bool

Returns: True if the box is homogeneous.

Returns whether the box is homogeneous (all children are the same size). See boxSetHomogeneous.

getSpacing

boxGetSpacing

Arguments

:: (HasCallStack, MonadIO m, IsBox a)

=> a

box: a Box

-> m Int32

Returns: spacing between children

Gets the value set by boxSetSpacing.

insertChildAfter

boxInsertChildAfter

Arguments

:: (HasCallStack, MonadIO m, IsBox a, IsWidget b, IsWidget c)

=> a

box: a Box

-> b

child: the Widget to insert

-> Maybe c

sibling: the sibling after which to insert child

-> m ()

Inserts child in the position after sibling in the list of box children. If sibling is Nothing, insert child at the first position.

new

boxNew

Arguments

:: (HasCallStack, MonadIO m)

=> Orientation

orientation: the box’s orientation

-> Int32

spacing: the number of pixels to place by default between children

-> m Box

Returns: a new Box.

Creates a new Box.

prepend

boxPrepend

Arguments

:: (HasCallStack, MonadIO m, IsBox a, IsWidget b)

Adds child as the first child to box.

remove

boxRemove

Arguments

:: (HasCallStack, MonadIO m, IsBox a, IsWidget b)

=> a

box: a Box

child: the child to remove

-> m ()

Removes a child widget from box, after it has been added with boxAppend, boxPrepend, or boxInsertChildAfter.

reorderChildAfter

Properties

baselinePosition

No description available in the introspection data.

constructBoxBaselinePosition :: (IsBox o, MonadIO m) => BaselinePosition -> m (GValueConstruct o)

Construct a GValueConstruct with valid value for the “baseline-position” property. This is rarely needed directly, but it is used by new.

getBoxBaselinePosition :: (MonadIO m, IsBox o) => o -> m BaselinePosition

Get the value of the “baseline-position” property. When overloading is enabled, this is equivalent to

get box #baselinePosition

setBoxBaselinePosition :: (MonadIO m, IsBox o) => o -> BaselinePosition -> m ()

Set the value of the “baseline-position” property. When overloading is enabled, this is equivalent to

set box [ #baselinePosition := value ]

homogeneous

No description available in the introspection data.

constructBoxHomogeneous :: (IsBox o, MonadIO m) => Bool -> m (GValueConstruct o)

Construct a GValueConstruct with valid value for the “homogeneous” property. This is rarely needed directly, but it is used by new.
