class Gtk::GridLayout

Overview

Gtk::GridLayout is a layout manager which arranges child widgets in rows and columns.

Children have an "attach point" defined by the horizontal and vertical index of the cell they occupy; children can span multiple rows or columns. The layout properties for setting the attach points and spans are set using the Gtk::GridLayoutChild associated to each child widget.

The behaviour of Gtk::GridLayout when several children occupy the same grid cell is undefined.

Gtk::GridLayout can be used like a Gtk::BoxLayout if all children are attached to the same row or column; however, if you only ever need a single row or column, you should consider using Gtk::BoxLayout.

Defined in:

lib/gi-crystal/src/auto/gtk-4.0/grid_layout.cr

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_row : Int32 #

Retrieves the row set with gtk_grid_layout_set_baseline_row().


[View source]
def baseline_row=(row : Int32) : Nil #

Sets which row defines the global baseline for the entire grid.

Each row in the grid can have its own local baseline, but only one of those is global, meaning it will be the baseline in the parent of the grid.


[View source]
def column_homogeneous : Bool #

Checks whether all columns of grid should have the same width.


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

Sets whether all columns of grid should have the same width.


[View source]
def column_homogeneous? : Bool #

[View source]
def column_spacing : UInt32 #

Retrieves the spacing set with gtk_grid_layout_set_column_spacing().


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

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

Sets the amount of space to insert between consecutive columns.


[View source]
def hash(hasher) #
Description copied from class Reference

See Object#hash(hasher)


def row_baseline_position(row : Int32) : Gtk::BaselinePosition #

Returns the baseline position of row.

If no value has been set with Gtk::GridLayout#row_baseline_position=, the default value of %GTK_BASELINE_POSITION_CENTER is returned.


[View source]
def row_homogeneous : Bool #

Checks whether all rows of grid should have the same height.


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

Sets whether all rows of grid should have the same height.


[View source]
def row_homogeneous? : Bool #

[View source]
def row_spacing : UInt32 #

Retrieves the spacing set with gtk_grid_layout_set_row_spacing().


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

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

Sets the amount of space to insert between consecutive rows.


[View source]
def set_row_baseline_position(row : Int32, pos : Gtk::BaselinePosition) : Nil #

Sets how the baseline should be positioned on row of the grid, in case that row is assigned more space than is requested.
