class Gtk::BoxLayout

Overview

Gtk::BoxLayout 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 Gtk::Orientable#orientation property. Within the other dimension all children all allocated the same size. The Gtk::BoxLayout will respect the Gtk::Widget#halign and Gtk::Widget#valign properties of each child widget.

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

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

Constructor Detail

def self.new(orientation : Gtk::Orientation) : self #

Creates a new Gtk::BoxLayout.


[View source]
def self.new #

Initialize a new BoxLayout.

def self.new(*, baseline_position : Gtk::BaselinePosition | Nil = nil, homogeneous : Bool | Nil = nil, orientation : Gtk::Orientation | Nil = nil, spacing : Int32 | Nil = nil) #

Class Method Detail

def self.g_type : UInt64 #

Returns the type id (GType) registered in GLib type system.

Instance Method Detail

def ==(other : self) #
Description copied from class Reference

Returns true if this reference is the same as other. Invokes same?.


def baseline_position : Gtk::BaselinePosition #

Gets the value set by gtk_box_layout_set_baseline_position().


[View source]
def baseline_position=(position : Gtk::BaselinePosition) : Nil #

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.

def hash(hasher) #
Description copied from class Reference

See Object#hash(hasher)


def homogeneous : Bool #

Returns whether the layout is set to be homogeneous.


[View source]
def homogeneous=(homogeneous : Bool) : Nil #

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


[View source]
def homogeneous? : Bool #

[View source]
def spacing : UInt32 #

Returns the space that box_layout puts between children.


[View source]
def spacing=(value : Int32) : Int32 #

[View source]
def spacing=(spacing : UInt32) : Nil #

Sets how much spacing to put between children.
