## Implemented Interfaces

GooCanvasTable implements GooCanvasItem.

## Description

GooCanvasTable is a table container used to lay out other canvas items. It is used in a similar way to how the GtkTable widget is used to lay out GTK+ widgets.

Items are added to the table using the normal methods, then `goo_canvas_item_set_child_properties()` is used to specify how each child item is to be positioned within the table (i.e. which row and column it is in, how much padding it should have and whether it should expand or shrink).

GooCanvasTable is a subclass of GooCanvasItemSimple and so inherits all of the style properties such as "stroke-color", "fill-color" and "line-width". Setting a style property on a GooCanvasTable will affect all children of the GooCanvasTable (unless the children override the property setting).

GooCanvasTable implements the GooCanvasItem interface, so you can use the GooCanvasItem functions such as `goo_canvas_item_raise()` and `goo_canvas_item_rotate()`, and the properties such as "visibility" and "pointer-events".

To create a GooCanvasTable use `goo_canvas_table_new()`.

To get or set the properties of an existing GooCanvasTable, use `g_object_get()` and `g_object_set()`.

## Functions

### goo_canvas_table_new ()

    GooCanvasItem *
    goo_canvas_table_new (GooCanvasItem *parent,
                          ...);

Creates a new table item.

Here's an example showing how to create a table with a square, a circle and a triangle in it:

                                          NULL);

#### Parameters

parent | the parent item, or `NULL`. If a parent is specified, it will assume ownership of the item, and the item will automatically be freed when it is removed from the parent. Otherwise call `g_object_unref()` to free it. | [skip]
... | optional pairs of property names and values, and a terminating `NULL`. |

#### Returns

a new table item.
