</h1><div class="doc"><p>The <code><a href="Graphics-UI-Gtk-Display-Label.html#t:Label">Label</a></code> widget displays a small amount of text. As the name implies,
most labels are used to label another widget such as a <code><a href="Graphics-UI-Gtk-Buttons-Button.html#t:Button">Button</a></code>, a
<code><a href="Graphics-UI-Gtk-MenuComboToolbar-MenuItem.html#t:MenuItem">MenuItem</a></code>, or a <code><a href="Graphics-UI-Gtk-MenuComboToolbar-OptionMenu.html#t:OptionMenu">OptionMenu</a></code>.
</p></div><h2 id="g:2">Mnemonics
</h2><div class="doc"><p>Labels may contain mnemonics. 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
<code>"_File"</code>, to the functions <code><a href="Graphics-UI-Gtk-Display-Label.html#v:labelNewWithMnemonic">labelNewWithMnemonic</a></code> or
<code><a href="Graphics-UI-Gtk-Display-Label.html#v:labelSetTextWithMnemonic">labelSetTextWithMnemonic</a></code>.
</p><p>Mnemonics automatically activate any activatable widget the label is
inside, such as a <code><a href="Graphics-UI-Gtk-Buttons-Button.html#t:Button">Button</a></code>; if the label is not inside the mnemonic's target
widget, you have to tell the label about the target using
<code><a href="Graphics-UI-Gtk-Display-Label.html#v:labelSetMnemonicWidget">labelSetMnemonicWidget</a></code>. Here's a simple example where the label is inside
a button: There's a convenience function to create buttons with a mnemonic
label already inside: To create a mnemonic for a widget alongside the label,
such as a <code><a href="Graphics-UI-Gtk-Entry-Entry.html#t:Entry">Entry</a></code>, you have to point the label at the entry with
<code><a href="Graphics-UI-Gtk-Display-Label.html#v:labelSetMnemonicWidget">labelSetMnemonicWidget</a></code>:
</p><pre> -- Pressing Alt+H will activate this button
button <- buttonNew
label <- labelNewWithMnemonic "_Hello"
containerAdd button label
</pre><pre> -- Pressing Alt+H will activate this button
button <- buttonNewWithMnemonic "_Hello"
</pre><pre> -- Pressing Alt+H will focus the entry
entry <- entryNew
label <- labelNewWithMnemonic "_Hello"
labelSetMnemonicWidget label entry
</pre></div><h2 id="g:3">Markup (styled text)
</h2><div class="doc"><p>To make it easy to format text in a label (changing colors, fonts, etc.),
label text can be provided in a simple markup format. Here's how to create a
label with a small font: (See complete documentation of available tags in
the Pango manual.)
</p><pre> label <- labelNew Nothing
labelSetMarkup label "<small>Small text</small>"
</pre><p>The markup passed to <code><a href="Graphics-UI-Gtk-Display-Label.html#v:labelSetMarkup">labelSetMarkup</a></code> must be valid; for example, literal
</>/& characters must be escaped as <code>"&lt;"</code>, <code>"&gt;"</code>, and
<code>"&amp;</code>". If you pass
text obtained from the user, file, or a network to <code><a href="Graphics-UI-Gtk-Display-Label.html#v:labelSetMarkup">labelSetMarkup</a></code>, you'll
want to escape it with <code><a href="/usr/share/doc/ghc/html/libraries/pango-0.12.0/Graphics-Rendering-Pango-Layout.html#v:escapeMarkup">escapeMarkup</a></code>.
</p></div><h2 id="g:4">Selectable labels
</h2><div class="doc"><p>Labels can be made selectable with <code><a href="Graphics-UI-Gtk-Display-Label.html#v:labelSetSelectable">labelSetSelectable</a></code>. Selectable
labels allow the user to copy the label contents to the clipboard. Only
labels that contain useful-to-copy information - such as error messages -
should be made selectable.
</p></div><h2 id="g:5">Text layout
</h2><div class="doc"><p>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.
</p><p>Labels can automatically wrap text if you call <code><a href="Graphics-UI-Gtk-Display-Label.html#v:labelSetLineWrap">labelSetLineWrap</a></code>.
</p><p><code><a href="Graphics-UI-Gtk-Display-Label.html#v:labelSetJustify">labelSetJustify</a></code> 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 <code>Graphics.UI.Gtk.Abstract.Misc.miscSetAlignment</code>.
