Implemented Interfaces

GooCanvasTextModel implements GooCanvasItemModel.

Description

GooCanvasTextModel represents a model for text items.

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

It also implements the GooCanvasItemModel interface, so you can use the GooCanvasItemModel functions such as goo_canvas_item_model_raise() and goo_canvas_item_model_rotate().

To create a GooCanvasTextModel use goo_canvas_text_model_new().

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

To respond to events such as mouse clicks on the text item you must connect to the signal handlers of the corresponding GooCanvasText objects. (See goo_canvas_get_item() and “item-created”.)

Functions

goo_canvas_text_model_new ()

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

Creates a new text model.

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

GooCanvasItemModel *text = goo_canvas_text_model_new (mygroup, "Hello World", 500.0, 500.0, 200.0, GOO_CANVAS_ANCHOR_SE,
                                                      "fill-color", "blue",
                                                      NULL);

Parameters

parent	the parent model, 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 model.
