<hr><h2><a name="details"></a>Detailed Description</h2>
The QLabel widget provides a static information display
<p>
QLabel is used for displaying information in the form of text or
image to the user. No user interaction functionality is
provided. The visual appearance of the label can be configured in
various ways, and it can be used for specifying a focus accelerator
key for another widget.
<p>A QLabel can contain any of the following content types:
<ul>
<li> A plain text: set by passing a <a href="qstring.html">QString</a> to <a href="#dffb43">setText</a>().
<li> A rich text: set by passing a QString that contains a rich text to setText().
<li> A pixmap: set by passing a <a href="qpixmap.html">QPixmap</a> to <a href="#f3f301">setPixmap</a>().
<li> A movie: set by passing a <a href="qmovie.html">QMovie</a> to <a href="#60de9f">setMovie</a>().
<li> A number: set by passing an <em>int</em> or a <em>double</em> to <a href="#1a8f6a">setNum</a>(), which converts the number to plain text.
<li> Nothing: The same as an empty plain text. This is the default. Set by <a href="#be73f3">clear</a>().
</ul>
<p>When the content is changed using any of these functions, any
previous content is cleared.
<p>The look of a QLabel can be tuned in several ways. All the settings
of <a href="qframe.html">QFrame</a> are available for specifying a widget frame. The
positioning of the content within the QLabel widget area can be
tuned with <a href="#1f406e">setAlignment</a>() and <a href="#ed9b8b">setIndent</a>(). For example, this code
sets up a sunken panel with a two-line text in the bottom right
corner (both lines being flush with the right side of the label):
<p><pre> <a href="qlabel.html">QLabel</a> *label = new <a href="qlabel.html">QLabel</a>;
label-><a href="qframe.html#c0d758">setFrameStyle</a>( QFrame::Panel | QFrame::Sunken );
label-><a href="#dffb43">setText</a>( "first line\nsecond line" );
label-><a href="#1f406e">setAlignment</a>( AlignBottom | AlignRight );
</pre>
<p>A QLabel is often used as a label for another, interactive
widget. For this use, QLabel provides a handy mechanism for adding
an accelerator key (see <a href="qaccel.html">QAccel</a>) that will set the keyboard focus to
the other widget (called the QLabel's "buddy"). Example:
<p><pre> <a href="qlineedit.html">QLineEdit</a>* phoneEdit = new <a href="qlineedit.html">QLineEdit</a>( this, "phoneEdit" );
<a href="qlabel.html">QLabel</a>* phoneLabel = new <a href="qlabel.html">QLabel</a>( phoneEdit, "&Phone:", this, "phoneLabel" );
</pre>
<p>In this example, keyboard focus is transferred to the label's buddy
(the <a href="qlineedit.html">QLineEdit</a>) when the user presses <dfn>Alt-P.</dfn> You can also
use the <a href="#191701">setBuddy</a>() function to accomplish the same.

<p><b>This function is obsolete.</b> It is provided to keep old source working, and will probably be removed in a future version of Qt. We strongly advise against using it in new code.<p>
Enables auto-resizing if <em>enable</em> is TRUE, or disables it if <em>enable</em> is FALSE.
<p>When auto-resizing is enabled, the label will resize itself to fit
the contents whenever the contents change. The top left corner is
not moved. This is useful for QLabel widgets that are not managed by
a <a href="qlayout.html">QLayout</a> (e.g. top-level widgets).
<p>Auto-resizing is disabled by default.
<p>See also <a href="#75b2a1">autoResize</a>(), <a href="qwidget.html#ab3108">adjustSize</a>() and <a href="#614dd5">sizeHint</a>().
<h3 class="fn">void <a name="191701"></a>QLabel::setBuddy ( <a href="qwidget.html">QWidget</a> * buddy ) <code>[virtual]</code></h3>
<p>Sets the buddy of this label to <em>buddy.</em>
<p>When the user presses the accelerator key indicated by this label,
the keyboard focus is transferred to the label's buddy widget.
<p>The buddy mechanism is only available for QLabels that contain a
plain text in which one letter is prefixed with '&'. It is this
letter that is set as the accelerator key. The letter is displayed
underlined, and the '&' is not displayed (i.e. the <code>ShowPrefix</code>
alignment flag is turned on; see <a href="#1f406e">setAlignment</a>()).
<p>In a dialog, you might create two data entry widgets and a label for
each, and set up the geometry layout so each label is just to the
left of its data entry widget (its "buddy"), somewhat like this:
<p><pre> <a href="qlineedit.html">QLineEdit</a> *nameEd = new <a href="qlineedit.html">QLineEdit</a>( this );
<a href="qlabel.html">QLabel</a> *nameLb = new <a href="qlabel.html">QLabel</a>( "&Name:", this );
nameLb-><a href="#191701">setBuddy</a>( nameEd );
<a href="qlineedit.html">QLineEdit</a> *phoneEd = new <a href="qlineedit.html">QLineEdit</a>( this );
<a href="qlabel.html">QLabel</a> *phoneLb = new <a href="qlabel.html">QLabel</a>( "&Phone:", this );
phoneLb-><a href="#191701">setBuddy</a>( phoneEd );
// ( layout setup not shown )
</pre>
<p>With the code above, the focus jumps to the Name field when the user
presses Alt-N, and to the Phone field when the user presses Alt-P.
<p>To unset a previously set buddy, call this function with <em>buddy</em>
set to 0.
<p>See also <a href="#123954">buddy</a>(), <a href="#dffb43">setText</a>(), <a href="qaccel.html">QAccel</a> and <a href="#1f406e">setAlignment</a>().
<p>Examples:
<a href="layout-layout-cpp.html#setBuddy">layout/layout.cpp</a>
<h3 class="fn">void <a name="ed9b8b"></a>QLabel::setIndent ( int indent )</h3>
<p>Sets the indent of the label to <em>indent</em> pixels.
<p>The indent applies to the left edge if <a href="#2fcaa3">alignment</a>() is <code>AlignLeft,</code>
to the right edge if alignment() is <code>AlignRight,</code> to the top edge
if alignment() is <code>AlignTop,</code> and to to the bottom edge if
alignment() is <code>AlignBottom.</code>
<p>If <em>indent</em> is negative, or if no indent has been set, the label
computes the effective indent as follows: If <a href="qframe.html#e0ccef">frameWidth</a>() is 0, the
effective indent becomes 0. If frameWidth() is greater than 0, the
effective indent becomes half the width of the "x" character of the
widget's current <a href="qwidget.html#3a7237">font</a>().
<p>If <em>indent</em> is non-negative, the effective indent is <em>indent</em>
pixels.

<h3 class="fn">void <a name="60de9f"></a>QLabel::setMovie ( const <a href="qmovie.html">QMovie</a> & movie ) <code>[virtual slot]</code></h3>
<p>Sets the label contents to <em>movie.</em> Any previous content is cleared.
<p>The buddy accelerator, if any, is disabled.
<p>The label resizes itself if auto-resizing is enabled.
<p>See also <a href="#7dcdfe">movie</a>() and <a href="#191701">setBuddy</a>().
<h3 class="fn">void <a name="1a8f6a"></a>QLabel::setNum ( double num ) <code>[virtual slot]</code></h3>
<p>Sets the label contents to a plain text containing the printed value
of <em>num.</em> Does nothing if this is equal to the current contents of
the label. Any previous content is cleared.
<p>The buddy accelerator, if any, is disabled.
<p>The label resizes itself if auto-resizing is enabled.
<p>See also <a href="#dffb43">setText</a>(), <a href="qstring.html#01d80b">QString::setNum</a>() and <a href="#191701">setBuddy</a>().
<h3 class="fn">void <a name="301e3c"></a>QLabel::setNum ( int num ) <code>[virtual slot]</code></h3>
<p>Sets the label contents to a plain text containing the printed value
of <em>num.</em> Does nothing if this is equal to the current contents of
the label. Any previous content is cleared.
<p>The buddy accelerator, if any, is disabled.
<p>The label resizes itself if auto-resizing is enabled.
<p>See also <a href="#dffb43">setText</a>(), <a href="qstring.html#01d80b">QString::setNum</a>() and <a href="#191701">setBuddy</a>().
<h3 class="fn">void <a name="f3f301"></a>QLabel::setPixmap ( const <a href="qpixmap.html">QPixmap</a> & pixmap ) <code>[virtual slot]</code></h3>
<p>Sets the label contents to <em>pixmap.</em> Any previous content is cleared.
<p>The buddy accelerator, if any, is disabled.
<p>The label resizes itself if auto-resizing is enabled.
<p>See also <a href="#101ecb">pixmap</a>() and <a href="#191701">setBuddy</a>().
<h3 class="fn">void <a name="e9e3cf"></a>QLabel::setScaledContents ( bool enable )</h3>
<p>When called with <em>enable</em> == TRUE, and the label shows a pixmap,
it will scale the pixmap to fill available space.
<p>See also <a href="#7e1f73">hasScaledContents</a>().
<h3 class="fn">void <a name="dffb43"></a>QLabel::setText ( const <a href="qstring.html">QString</a> & text ) <code>[virtual slot]</code></h3>
<p>Sets the label contents to <em>text,</em> or does nothing if <em>text</em> is
equal to the current contents of the label. Any previous content is
cleared.
<p><em>text</em> will be interpreted either as a plain text or as a rich
text, depending on the text format setting; see <a href="#5de3f9">setTextFormat</a>(). The
default setting is <code>AutoText,</code> i.e. QLabel will try to auto-detect
the format of <em>text.</em>
<p>If <em>text</em> is interpreted as a plain text, and a buddy has been set,
the buddy accelerator key is updated from the new text.
<p>The label resizes itself if auto-resizing is enabled.
<p>Note that Qlabel is well suited to display small rich text documents
only. For large documents, use <a href="qtextview.html">QTextView</a> instead. It will flicker
less on resize and can also provide a scrollbar if necessary.
