## Implemented Interfaces

GocStyledItem implements GOStyledObject.

## Properties

      "scale-line-width"         gboolean              : Read / Write
      "style"                    GOStyle*              : Read / Write

## Signals

      "style-changed"                                  : Run Last

## Description

The virtual base object for canvas items with style.

## Details

### GocStyledItem

    typedef struct _GocStyledItem GocStyledItem;

### GocStyledItemClass

    typedef struct {
    	/* virtual */
    	void	  (*init_style)     	(GocStyledItem *item, GOStyle *style);
    } GocStyledItemClass;

`init_style` () | style initialization handler.

### goc_styled_item_set_cairo_line ()

    gboolean            goc_styled_item_set_cairo_line      (GocStyledItem const *gsi,
                                                             cairo_t *cr);

Prepares the cairo context `cr` to draw a line according to the item style and canvas scale. The line width is scaled only if the scale-line-width property is set to `TRUE`. This function calls `go_styled_object_set_cairo_line()`.

If the item drawing used `goc_group_cairo_transform()`, scale-line-width should be `FALSE` to avoid scaling twice, or `go_styled_object_set_cairo_line()` should be called directly instead.

`gsi` : | GocStyledItem
`cr` : | cairo_t
Returns : | `TRUE` if the line is not invisible

## Property Details

### The `"scale-line-width"` property

      "scale-line-width"         gboolean              : Read / Write

Whether to scale the line width when zooming.

Default value: TRUE

### The `"style"` property

      "style"                    GOStyle*              : Read / Write

A pointer to the GOStyle object.

## Signal Details

### The `"style-changed"` signal

    void                user_function                      (GocStyledItem *gsi,
                                                            GObject       *style,
                                                            gpointer       user_data)      : Run Last

The ::style-changed signal is emitted when a new style has been set on a styled item.

`gsi` : | the object on which the signal is emitted
`style` : | the new GOStyle.
`user_data` : | user data set when the signal handler was connected.
