# ClutterGridLayout

#### Description [src]

    final class Clutter.GridLayout : Clutter.LayoutManager
    {
      /* No available fields */
    }

A layout manager for a grid of actors

`ClutterGridLayout` is a layout manager which arranges its child widgets in rows and columns. It is a very similar to `ClutterBoxLayout`, but it consistently uses `ClutterActor`‘s alignment and expansion flags instead of custom child properties.

Children are added using `clutter_grid_layout_attach()`. They can span multiple rows or columns. It is also possible to add a child next to an existing child, using `clutter_grid_layout_attach_next_to()`. The behaviour of `ClutterGridLayout` when several children occupy the same grid cell is undefined.

`ClutterGridLayout` can be used like a `ClutterBoxLayout` by just using `clutter_actor_add_child()`, which will place children next to each other in the direction determined by the `ClutterGridLayout:orientation` property.

###### clutter_layout_manager_child_set_property

Sets a property on the `ClutterLayoutMeta` created by `manager` and attached to a child of `container`.

###### clutter_layout_manager_find_child_property

Retrieves the `GParamSpec` for the layout property `name` inside the `ClutterLayoutMeta` sub-class used by `manager`.

###### clutter_layout_manager_get_child_meta

Retrieves the `ClutterLayoutMeta` that the layout `manager` associated to the `actor` child of `container`, eventually by creating one if the `ClutterLayoutManager` supports layout properties.

###### clutter_layout_manager_list_child_properties

Retrieves all the `GParamSpec`s for the layout properties stored inside the `ClutterLayoutMeta` sub-class used by `manager`.

###### clutter_layout_manager_set_container

If the `ClutterLayoutManager` sub-class allows it, allow adding a weak reference of the `container` using `manager` from within the layout manager.

##### Methods inherited from GObject (43)

Please see GObject for a full list of methods.

#### Properties

###### Clutter.GridLayout:column-homogeneous

Whether all columns of the layout should have the same width.

###### Clutter.GridLayout:column-spacing

The amount of space in pixels between two consecutive columns.

###### Clutter.GridLayout:orientation

The orientation of the layout, either horizontal or vertical.

###### Clutter.GridLayout:row-homogeneous

Whether all rows of the layout should have the same height.

###### Clutter.GridLayout:row-spacing

The amount of space in pixels between two consecutive rows.

#### Signals

##### Signals inherited from ClutterLayoutManager (1)

###### ClutterLayoutManager::layout-changed

The signal is emitted each time a layout manager has been changed. Every `ClutterActor` using the `manager` instance as a layout manager should connect a handler to the `ClutterLayoutManager::layout-changed` signal and queue a relayout on themselves:.

##### Signals inherited from GObject (1)

###### GObject::notify

The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
