Class

GtkGrid

Description [src] 

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

Arranges its child widgets in rows and columns.

An example GtkGrid

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.
