<p>This widget is used to enter pixel distances/sizes and resolutions.</p>
<p>You can specify the number of fields the widget should provide. For
each field automatic mappings are performed between the field's
"reference value" and its "value".</p>
<p>There is a <a class="link" href="GimpUnitComboBox.html" title="GimpUnitComboBox"><span class="type">GimpUnitComboBox</span></a> right of the entry fields which lets
you specify the <a href="../html/libgimpbase-gimpunit.html#GimpUnit"><span class="type">GimpUnit</span></a> of the displayed values.</p>
<p>For each field, there can be one or two <a href="https://developer.gnome.org/gtk3/GtkSpinButton.html#GtkSpinButton-struct"><span class="type">GtkSpinButton</span></a>'s to enter
"value" and "reference value". If you specify <em class="parameter"><code>show_refval</code></em>
as
<span class="type">FALSE</span> in <a class="link" href="GimpSizeEntry.html#gimp-size-entry-new" title="gimp_size_entry_new ()"><code class="function">gimp_size_entry_new()</code></a> there will be only one
<a href="https://developer.gnome.org/gtk3/GtkSpinButton.html#GtkSpinButton-struct"><span class="type">GtkSpinButton</span></a> and the <a class="link" href="GimpUnitComboBox.html" title="GimpUnitComboBox"><span class="type">GimpUnitComboBox</span></a> will contain an item for
selecting GIMP_UNIT_PIXEL.</p>
<p>The "reference value" is either of GIMP_UNIT_PIXEL or dpi,
depending on which <a class="link" href="GimpSizeEntry.html#GimpSizeEntryUpdatePolicy" title="enum GimpSizeEntryUpdatePolicy"><span class="type">GimpSizeEntryUpdatePolicy</span></a> you specify in
<a class="link" href="GimpSizeEntry.html#gimp-size-entry-new" title="gimp_size_entry_new ()"><code class="function">gimp_size_entry_new()</code></a>. The "value" is either the size in pixels
mapped to the size in a real-world-unit (see <a href="../html/libgimpbase-gimpunit.html#GimpUnit"><span class="type">GimpUnit</span></a>) or the dpi
value mapped to pixels per real-world-unit.</p>
