pango_layout_get_serial (<em class="parameter"><code><a class="link" href="pango-Layout-Objects.html#PangoLayout"><span class="type">PangoLayout</span></a> *layout</code></em>);</pre>
<p>Returns the current serial number of <em class="parameter"><code>layout</code></em>
. The serial number is
initialized to an small number larger than zero when a new layout
is created and is increased whenever the layout is changed using any
of the setter functions, or the <a class="link" href="pango-Text-Processing.html#PangoContext"><span class="type">PangoContext</span></a> it uses has changed.
The serial may wrap, but will never have the value 0. Since it
can wrap, never compare it with "less than", always use "not equals".</p>
<p>This can be used to automatically detect changes to a <a class="link" href="pango-Layout-Objects.html#PangoLayout"><span class="type">PangoLayout</span></a>, and
is useful for example to decide whether a layout needs redrawing.

<p>Sets the height to which the <a class="link" href="pango-Layout-Objects.html#PangoLayout"><span class="type">PangoLayout</span></a> should be ellipsized at. There
are two different behaviors, based on whether <em class="parameter"><code>height</code></em>
is positive or
negative.</p>
<p>If <em class="parameter"><code>height</code></em>
is positive, it will be the maximum height of the layout. Only
lines would be shown that would fit, and if there is any text omitted,
an ellipsis added. At least one line is included in each paragraph regardless
of how small the height value is. A value of zero will render exactly one
line for the entire layout.</p>
<p>If <em class="parameter"><code>height</code></em>
is negative, it will be the (negative of) maximum number of lines per
paragraph. That is, the total number of lines shown may well be more than
this value if the layout contains multiple paragraphs of text.
The default value of -1 means that first line of each paragraph is ellipsized.
This behvaior may be changed in the future to act per layout instead of per
paragraph. File a bug against pango at <a class="ulink" href="http://bugzilla.gnome.org/" target="_top">http://bugzilla.gnome.org/</a> if your
code relies on this behavior.</p>
<p>Height setting only has effect if a positive width is set on
<em class="parameter"><code>layout</code></em>

is not <a class="link" href="pango-Layout-Objects.html#PANGO-ELLIPSIZE-NONE:CAPS"><code class="literal">PANGO_ELLIPSIZE_NONE</code></a>.
The behavior is undefined if a height other than -1 is set and
ellipsization mode is set to <a class="link" href="pango-Layout-Objects.html#PANGO-ELLIPSIZE-NONE:CAPS"><code class="literal">PANGO_ELLIPSIZE_NONE</code></a>, and may change in the

removed from the start, middle, or end of text so they
