BoxLayout

class BoxLayout(**properties: Any)

Superclasses: LayoutManager, Object

Implemented Interfaces: Orientable

GtkBoxLayout is a layout manager that arranges children in a single row or column.

Whether it is a row or column depends on the value of its orientation property. Within the other dimension all children all allocated the same size. The GtkBoxLayout will respect the halign and valign properties of each child widget.

If you want all children to be assigned the same size, you can use the homogeneous property.

If you want to specify the amount of space placed between each child, you can use the spacing property.

Constructors

class BoxLayout

classmethod new(orientation: Orientation) → LayoutManager

Creates a new GtkBoxLayout.

Parameters:

orientation – the orientation for the new layout

Methods

class BoxLayout

get_baseline_child() → int

Gets the value set by set_baseline_child().

Added in version 4.12.

get_baseline_position() → BaselinePosition

Gets the value set by set_baseline_position().

get_homogeneous() → bool

Returns whether the layout is set to be homogeneous.

get_spacing() → int

Returns the space that box_layout puts between children.

set_baseline_child(child: int) → None

Sets the index of the child that determines the baseline in vertical layout.

Added in version 4.12.

Parameters:

child – the child position, or -1

set_baseline_position(position: BaselinePosition) → None

Sets the baseline position of a box layout.

The baseline position affects only horizontal boxes with at least one baseline aligned child. If there is more vertical space available than requested, and the baseline is not allocated by the parent then the given position is used to allocate the baseline within the extra space available.

Parameters:

position – a GtkBaselinePosition

set_homogeneous(homogeneous: bool) → None

Sets whether the box layout will allocate the same size to all children.

Parameters:

homogeneous – True to set the box layout as homogeneous

set_spacing(spacing: int) → None

Sets how much spacing to put between children.

Parameters:

spacing – the spacing to apply between children
