<!-- ##### SECTION Title ##### -->
GtkLabel

<!-- ##### SECTION Short_Description ##### -->
A widget that displays a small to medium amount of text

<!-- ##### SECTION Long_Description ##### -->
<para>
The #GtkLabel widget displays a small amount of text. As the name
implies, most labels are used to label another widget such as a
#GtkButton, a #GtkMenuItem, or a #GtkOptionMenu.
</para>

<refsect2 id="GtkLabel-BUILDER-UI">
<title>GtkLabel as GtkBuildable</title>
<para>
The GtkLabel implementation of the GtkBuildable interface supports a 
custom &lt;attributes&gt; element, which supports any number of &lt;attribute&gt;
elements. the &lt;attribute&gt; element has attributes named name, value,
start and end and allows you to specify #PangoAttribute values for this label.
</para>
<example>
<title>A UI definition fragment specifying Pango attributes</title>
<programlisting><![CDATA[
<object class="GtkLabel">
  <attributes>
    <attribute name="weight" value="PANGO_WEIGHT_BOLD"/>
    <attribute name="background" value="red" start="5" end="10"/>"
  </attributes>
</object>
]]></programlisting>
</example>
<para>
The start and end attributes specify the range of characters to which the
Pango attribute applies. If start and end are not specified, the attribute is
applied to the whole text. Note that specifying ranges does not make much
sense with translatable attributes. Use markup embedded in the translatable
content instead.
</para>
</refsect2>


<refsect2>
<title>Mnemonics</title>

<para>
Labels may contain <firstterm>mnemonics</firstterm>. Mnemonics are
underlined characters in the label, used for keyboard navigation.
Mnemonics are created by providing a string with an underscore before
the mnemonic character, such as <literal>"_File"</literal>, to the
functions gtk_label_new_with_mnemonic() or
gtk_label_set_text_with_mnemonic().
</para>

<para>
Mnemonics automatically activate any activatable widget the label is
inside, such as a #GtkButton; if the label is not inside the
mnemonic's target widget, you have to tell the label about the target
using gtk_label_set_mnemonic_widget(). Here's a simple example where
the label is inside a button:

<informalexample>
<programlisting>
  /* Pressing Alt+H will activate this button */
  button = gtk_button_new (<!-- -->);
  label = gtk_label_new_with_mnemonic ("_Hello");
  gtk_container_add (GTK_CONTAINER (button), label);
</programlisting>
</informalexample>
There's a convenience function to create buttons with a mnemonic label 
already inside:

<informalexample>
<programlisting>
  /* Pressing Alt+H will activate this button */
  button = gtk_button_new_with_mnemonic ("_Hello");
</programlisting>
</informalexample>

To create a mnemonic for a widget alongside the label, such as a 
#GtkEntry, you have to point the label at the entry with 
gtk_label_set_mnemonic_widget():
<informalexample>
<programlisting>
  /* Pressing Alt+H will focus the entry */
  entry = gtk_entry_new (<!-- -->);
  label = gtk_label_new_with_mnemonic ("_Hello");
  gtk_label_set_mnemonic_widget (GTK_LABEL (label), entry);
</programlisting>
</informalexample>

</para>

</refsect2>

<refsect2>
<title>Markup (styled text)</title>

<para>
To make it easy to format text in a label (changing colors, fonts,
etc.), label text can be provided in a simple <link
linkend="PangoMarkupFormat">markup format</link>.
Here's how to create a label with a small font:
<informalexample>
<programlisting>
  label = gtk_label_new (NULL);
  gtk_label_set_markup (GTK_LABEL (label), "&lt;small&gt;Small text&lt;/small&gt;");
</programlisting>
</informalexample>
(See <link
linkend="PangoMarkupFormat">complete documentation</link> of available
tags in the Pango manual.)
</para>
<para>
The markup passed to gtk_label_set_markup() must be valid; for example,
literal &lt;/&gt;/&amp; characters must be escaped as &amp;lt;,
&amp;gt;, and &amp;amp;. If you pass text obtained from the user, file,
or a network to gtk_label_set_markup(), you'll want to escape it with
g_markup_escape_text() or g_markup_printf_escaped().
</para>
<para>
Markup strings are just a convenient way to set the #PangoAttrList on
a label; gtk_label_set_attributes() may be a simpler way to set
attributes in some cases. Be careful though; #PangoAttrList tends to
cause internationalization problems, unless you're applying attributes
to the entire string (i.e. unless you set the range of each attribute
to [0, G_MAXINT)). The reason is that specifying the start_index and
end_index for a #PangoAttribute requires knowledge of the exact string
being displayed, so translations will cause problems.
</para>
</refsect2>

<refsect2>
<title>Selectable labels</title>

<para>
Labels can be made selectable with gtk_label_set_selectable(). 
Selectable labels allow the user to copy the label contents to 
the clipboard. Only labels that contain useful-to-copy information
&mdash; such as error messages &mdash; should be made selectable.
</para>
</refsect2>

<refsect2>
<title>Text layout</title>

<para>
A label can contain any number of paragraphs, but will have
performance problems if it contains more than a small number.
Paragraphs are separated by newlines or other paragraph separators
understood by Pango.
</para>
<para>
Labels can automatically wrap text if you call
gtk_label_set_line_wrap().
</para>
<para>
gtk_label_set_justify() sets how the lines in a label align 
with one another. If you want to set how the label as a whole 
aligns in its available space, see gtk_misc_set_alignment().

Parses the given string for underscores and converts the next
character to an underlined character.  The last character that
was underlined will have its lower-cased accelerator keyval returned  (i.e.
&quot;_File&quot; would return the keyval for &quot;f&quot;.  This is
probably only used within the GTK+ library itself for menu items and such.
