GooCanvasImageViewGooCanvasImageView — a view for a GooCanvasImage item. |
#include <goocanvas.h> GooCanvasImageView; GooCanvasItemView* goo_canvas_image_view_new (GooCanvasView *canvas_view, GooCanvasItemView *parent_view, GooCanvasImage *image);
GooCanvasImageView represents a view of a GooCanvasImage item.
It implements the GooCanvasItemView interface, so you can use the
GooCanvasItemView functions such as goo_canvas_item_view_get_item()
and goo_canvas_item_view_get_bounds()
.
Applications do not normally need to create item views themselves, as they are created automatically by GooCanvasView when needed.
To respond to events such as mouse clicks in the ellipse view you can
connect to one of the GooCanvasItemView signals such as
GooCanvasItemView::button-press-event. You can connect to these signals
when the view is created. (See goo_canvas_view_get_item_view()
and
GooCanvasView::item-view-created.)
typedef struct _GooCanvasImageView GooCanvasImageView;
The GooCanvasImageView struct contains private data only.
GooCanvasItemView* goo_canvas_image_view_new (GooCanvasView *canvas_view, GooCanvasItemView *parent_view, GooCanvasImage *image);
Creates a new GooCanvasImageView for the given GooCanvasImage item.
This is not normally used by application code, as the views are created automatically by GooCanvasView.
