DESCRIPTION

gnome_canvas_FIXME_hard_update

 /opt/src/beast/beast-gtk/gxk/gxkcanvas.h:45
void  gnome_canvas_FIXME_hard_update  
(GnomeCanvas *canvas);

gnome_canvas_item_check_undisposed

 /opt/src/beast/beast-gtk/gxk/gxkcanvas.h:33
gboolean  gnome_canvas_item_check_undisposed  
(GnomeCanvasItem *item);

gnome_canvas_item_get_stacking

 /opt/src/beast/beast-gtk/gxk/gxkcanvas.h:34
guint  gnome_canvas_item_get_stacking  
(GnomeCanvasItem *item);

gnome_canvas_item_keep_above

 /opt/src/beast/beast-gtk/gxk/gxkcanvas.h:40
void  gnome_canvas_item_keep_above  
(GnomeCanvasItem *above,
 GnomeCanvasItem *item1,
 GnomeCanvasItem *item2);

gnome_canvas_item_keep_between

 /opt/src/beast/beast-gtk/gxk/gxkcanvas.h:37
void  gnome_canvas_item_keep_between  
(GnomeCanvasItem *between,

gnome_canvas_points_new0

 /opt/src/beast/beast-gtk/gxk/gxkcanvas.h:26
 GnomeCanvasPoints*  gnome_canvas_points_new0  
(guint num_points);

GnomeCanvasPoints*  gnome_canvas_points_newv  
(guint num_points,
 ...);

gnome_canvas_set_zoom

 /opt/src/beast/beast-gtk/gxk/gxkcanvas.h:44
void  gnome_canvas_set_zoom  
(GnomeCanvas *canvas,
 gdouble      pixels_per_unit);
This function calls gnome_canvas_set_pixels_per_unit() with its arguments and in addition adjusts the font sizes of all canvas text items where gnome_canvas_text_set_zoom_size() was used before.
canvas: valid GnomeCanvas
pixels_per_unit: zoom factor (defaults to 1.0)
