Changes the icon for a widget to a given widget. GTK+
will not destroy the icon, so if you don't want
it to persist, you should connect to the "drag_end" 
signal and destroy it yourself.</p>

Sets <em class="parameter"><code>pixmap</code></em> as the icon for a given drag. GTK+ retains
references for the arguments, and will release them when
they are no longer needed. In general, <a class="link" href="gtk-Drag-and-Drop.html#gtk-drag-set-icon-pixbuf"><code class="function">gtk_drag_set_icon_pixbuf()</code></a>

Sets the icon for a given drag from a named themed icon. See
the docs for <a class="link" href="GtkIconTheme.html" title="GtkIconTheme"><span class="type">GtkIconTheme</span></a> for more details. Note that the
size of the icon depends on the icon theme (the icon is
loaded at the symbolic size <span class="type">GTK_ICON_SIZE_DND</span>), thus 
<em class="parameter"><code>hot_x</code></em> and <em class="parameter"><code>hot_y</code></em> have to be used with care.</p>
