## Description

GooCanvasText represents a text item.

It is a subclass of GooCanvasItemSimple and so inherits all of the style properties such as "fill-color".

It also implements the GooCanvasItem interface, so you can use the GooCanvasItem functions such as `goo_canvas_item_raise()` and `goo_canvas_item_rotate()`.

The "width" and "height" properties specify the area of the item. If it exceeds that area because there is too much text, it is clipped. The properties can be set to -1 to disable clipping.

To create a GooCanvasText use `goo_canvas_text_new()`.

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

## Details

### struct GooCanvasText

    struct GooCanvasText;

The GooCanvasText struct contains private data only.

### goo_canvas_text_new ()

    GooCanvasItem *     goo_canvas_text_new                 (GooCanvasItem *parent,
                                                             const char *string,
                                                             gdouble x,
                                                             gdouble y,
                                                             gdouble width,
                                                             GooCanvasAnchorType anchor,
                                                             ...);

Creates a new text item.

`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]
`string` : | the text to display.
`x` : | the x coordinate of the text.
`y` : | the y coordinate of the text.
`width` : | the width of the text item, or -1 for unlimited width.
`anchor` : | the position of the text relative to the given `x` and `y` coordinates. For example an anchor of `GDK_ANCHOR_NW` will result in the top-left of the text being placed at the given `x` and `y` coordinates. An anchor of `GDK_ANCHOR_CENTER` will result in the center of the text being placed at the `x` and `y` coordinates.
`...` : | optional pairs of property names and values, and a terminating `NULL`.
Returns : | a new text item. [transfer full]

Here's an example showing how to create a text item with the bottom right of the text box placed at (500,500):

    1
    2
    3
    GooCanvasItem *text = goo_canvas_text_new (mygroup, "Hello World", 500.0, 500.0, 200.0, GOO_CANVAS_ANCHOR_SE,
                                               "fill-color", "blue",
                                               NULL);

### goo_canvas_text_get_natural_extents ()

    void                goo_canvas_text_get_natural_extents (GooCanvasText *text,
                                                             PangoRectangle *ink_rect,
                                                             PangoRectangle *logical_rect);

Gets the natural extents of the text, in the text item's coordinate space.

The final extents of the text may be different, if the text item is placed in a layout container such as GooCanvasTable.

`text` : | a GooCanvasText.
`ink_rect` : | the location to return the ink rect, or `NULL`.
`logical_rect` : | the location to return the logical rect, or `NULL`.
