The GnomeIconTextItem canvas item
provides a specialized, editable text item to be used for the text
captions of icons. This item is used by the
GnomeIconList widget and by the GNOME
file manager.
Details
struct GnomeIconTextItem
struct GnomeIconTextItem;
All the fields in the GnomeIconTextItem
structure should be considered private. When the application
needs to know the size and bounds of an icon text item, it should
use the gnome_canvas_item_get_bounds()
function.
gnome_icon_text_item_configure ()
void gnome_icon_text_item_configure (GnomeIconTextItem *iti,
int x,
int y,
int width,
const char *fontname,
const char *text,
gboolean is_editable,
gboolean is_static);
This routine is used to configure a &GnomeIconTextItem.
x and y specify the cordinates where the item is placed inside the canvas.
The x coordinate should be the leftmost position that the icon text item can
assume at any one time, that is, the left margin of the column in which the
icon is to be placed. The y coordinate specifies the top of the icon text
item.
width is the maximum width allowed for this icon text item. The coordinates
define the upper-left corner of an icon text item with maximum width; this may
actually be outside the bounding box of the item if the text is narrower than
the maximum width.
If is_static is true, it means that there is no need for the item to
allocate memory for the string (it is a guarantee that the text is allocated
by the caller and it will not be deallocated during the lifetime of this
item). This is an optimization to reduce memory usage for large icon sets.

when the user clicks on a selected icon text item, it will start the text
editing process.
