## Description

## Details

### ECanvasItemSelectionFunc ()

    void                (*ECanvasItemSelectionFunc)         (GnomeCanvasItem *item,
                                                             gint flags,

### ECanvasSelectionInfo

    typedef struct {
    	GnomeCanvasItem *item;
    	gpointer         id;
    } ECanvasSelectionInfo;

### struct ECanvas

    struct ECanvas;

### e_canvas_new ()

    GtkWidget *         e_canvas_new                        (void);

### e_canvas_item_grab_focus ()

    void                e_canvas_item_grab_focus            (GnomeCanvasItem *item,

Makes the specified item take the keyboard focus, so all keyboard events will be sent to it. If the canvas widget itself did not have the focus and `widget_too` is `TRUE`, it grabs that focus as well.

`item` : | A canvas item.
`widget_too` : | Whether or not to grab the widget-level focus too
