<p>This widget provides a <a href="/usr/share/gtk-doc/html/gtk2/GtkOptionMenu.html#GtkOptionMenu-struct"><span class="type">GtkOptionMenu</span></a> which contains a list of
<a href="../html/libgimpbase-gimpunit.html#GimpUnit"><span class="type">GimpUnit</span></a>'s.</p>
<p>You can specify the string that will be displayed for each unit by
passing a printf-like <em class="parameter"><code>format</code></em>
 string to <a class="link" href="GimpUnitMenu.html#gimp-unit-menu-new" title="gimp_unit_menu_new ()"><code class="function">gimp_unit_menu_new()</code></a>.</p>
<p>The constructor also lets you choose if the menu should contain
items for GIMP_UNIT_PIXEL, GIMP_UNIT_PERCENT and a "More..." item
which will pop up a dialog for selecting user-defined units.</p>
<p>Whenever the user selects a unit from the menu or the dialog, the
"unit_changed" signal will be emitted.</p>

<p>A GimpUnitMenu can be setup to control the number of digits shown
by attached spinbuttons. Please refer to the documentation of
<a class="link" href="libgimpwidgets-GimpOldWidgets.html#gimp-unit-menu-update" title="gimp_unit_menu_update ()"><code class="function">gimp_unit_menu_update()</code></a> to see how this is done.</p>
<p>This function allows to specify the number of digits shown for a
size in pixels. Usually this is 0 (only full pixels). If you want
to allow the user to specify sub-pixel sizes using the attached
spinbuttons, specify the number of digits after the decimal point
here. You should do this after attaching your spinbuttons.</p>
