### Class

# Gtk Grid

since: 4.0

#### Description [src]

    class Gtk.Grid : Gtk.Widget
      implements Gtk.Accessible, Gtk.Buildable, Gtk.ConstraintTarget, Gtk.Orientable {
      /* No available fields */
    }

`GtkGrid` is a container which arranges its child widgets in rows and columns.

It supports arbitrary positions and horizontal/vertical spans.

Children are added using `gtk_grid_attach()`. They can span multiple rows or columns. It is also possible to add a child next to an existing child, using `gtk_grid_attach_next_to()`. To remove a child from the grid, use `gtk_grid_remove()`.

The behaviour of `GtkGrid` when several children occupy the same grid cell is undefined.

# GtkGrid as GtkBuildable

Every child in a `GtkGrid` has access to a custom `GtkBuildable` element, called `<layout>`. It can by used to specify a position in the grid and optionally spans. All properties that can be used in the `<layout>` element are implemented by `GtkGridLayoutChild`.

It is implemented by `GtkWidget` using `GtkLayoutManager`.

To showcase it, here is a simple example:

    <object class="GtkGrid" id="my_grid">
      <child>
        <object class="GtkButton" id="button1">
          <property name="label">Button 1</property>
          <layout>
            <property name="column">0</property>
            <property name="row">0</property>
          </layout>
        </object>
      </child>
      <child>
        <object class="GtkButton" id="button2">
          <property name="label">Button 2</property>
          <layout>
            <property name="column">1</property>
            <property name="row">0</property>
          </layout>
        </object>
      </child>
      <child>
        <object class="GtkButton" id="button3">
          <property name="label">Button 3</property>
          <layout>
            <property name="column">2</property>
            <property name="row">0</property>
            <property name="row-span">2</property>
          </layout>
        </object>
      </child>
      <child>
        <object class="GtkButton" id="button4">
          <property name="label">Button 4</property>
          <layout>
            <property name="column">0</property>
            <property name="row">1</property>
            <property name="column-span">2</property>
          </layout>
        </object>
      </child>
    </object>

It organizes the first two buttons side-by-side in one cell each. The third button is in the last column but spans across two rows. This is defined by the `row-span` property. The last button is located in the second row and spans across two columns, which is defined by the `column-span` property.

# CSS nodes

`GtkGrid` uses a single CSS node with name `grid`.

# Accessibility

Until GTK 4.10, `GtkGrid` used the `GTK_ACCESSIBLE_ROLE_GROUP` role.

Starting from GTK 4.12, `GtkGrid` uses the `GTK_ACCESSIBLE_ROLE_GENERIC` role.
