This widget provides a <a

><span class="type">GtkOptionMenu</span></a> which contains a list of <a
href="../libgimpbase/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 <i class="parameter"><tt>format</tt></i> string to <a href="GimpUnitMenu.html#gimp-unit-menu-new"><tt class="function">gimp_unit_menu_new()</tt></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.

A GimpUnitMenu can be setup to control the number of digits shown
by attached spinbuttons. Please refer to the documentation of
<a href="libgimpwidgets-GimpWidgets.html#gimp-unit-menu-update"><tt class="function">gimp_unit_menu_update()</tt></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><p>
