.SH DESCRIPTION
The QIconViewItem class implements an iconview item.
.PP
An iconview item is a object containing an icon and a text, which can display itself in an iconview.
.PP
The simplest way to create an iconview item and insert it into an iconview is to construct it with a pointer to the iconview, a string and an icon:
.PP
.nf
.br
    // parent is a pointer to our iconview, pixmap a QPixmap,
.br
    // which we want to use as icon
.br
    (void) new QIconViewItem( parent,
.br
                              "This is the text of the item",
.br
                              pixmap );
.fi
.PP
When the iconview is deleted, all items of it are deleted automatically, so the programmer need not delete the iconview items itself.
.PP
To iterate over all items of an iconview do something like
.PP
.nf
