The TQLabel widget provides a text or image display.
<p>
<p> TQLabel is used for displaying text or an image. 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 TQLabel can contain any of the following content types:
<center><table cellpadding="4" cellspacing="2" border="0">
<tr bgcolor="#a2c511"> <th valign="top">Content <th valign="top">Setting
<tr bgcolor="#f0f0f0"> <td valign="top">Plain text
<td valign="top">Pass a <a href="ntqstring.html">TQString</a> to <a href="#setText">setText</a>().
<tr bgcolor="#d0d0d0"> <td valign="top">Rich text
<td valign="top">Pass a TQString that contains rich text to setText().
<tr bgcolor="#f0f0f0"> <td valign="top">A pixmap
<td valign="top">Pass a <a href="ntqpixmap.html">TQPixmap</a> to <a href="#setPixmap">setPixmap</a>().
<tr bgcolor="#d0d0d0"> <td valign="top">A movie
<td valign="top">Pass a <a href="ntqmovie.html">TQMovie</a> to <a href="#setMovie">setMovie</a>().
<tr bgcolor="#f0f0f0"> <td valign="top">A number
<td valign="top">Pass an <em>int</em> or a <em>double</em> to <a href="#setNum">setNum</a>(), which converts
the number to plain text.
<tr bgcolor="#d0d0d0"> <td valign="top">Nothing
<td valign="top">The same as an empty plain text. This is the default. Set
by <a href="#clear">clear</a>().
</table></center>
<p> When the content is changed using any of these functions, any
previous content is cleared.
<p> The look of a TQLabel can be tuned in several ways. All the
settings of <a href="ntqframe.html">TQFrame</a> are available for specifying a widget frame.
The positioning of the content within the TQLabel widget area can
be tuned with <a href="#setAlignment">setAlignment</a>() and <a href="#setIndent">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):
<pre>
TQLabel *label = new TQLabel( this );
label-><a href="ntqframe.html#setFrameStyle">setFrameStyle</a>( TQFrame::<a href="ntqframe.html#Shape-enum">Panel</a> | TQFrame::<a href="ntqframe.html#Shadow-enum">Sunken</a> );
label-><a href="#setText">setText</a>( "first line\nsecond line" );
label-><a href="#setAlignment">setAlignment</a>( AlignBottom | AlignRight );
</pre>
<p> A TQLabel is often used as a label for an interactive widget. For
this use TQLabel provides a useful mechanism for adding an
accelerator key (see <a href="ntqaccel.html">TQAccel</a>) that will set the <a href="focus.html#keyboard-focus">keyboard focus</a> to
the other widget (called the TQLabel's "buddy"). For example:
<pre>
<a href="ntqlineedit.html">TQLineEdit</a>* phoneEdit = new <a href="ntqlineedit.html">TQLineEdit</a>( this, "phoneEdit" );
TQLabel* phoneLabel = new TQLabel( phoneEdit, "&Phone:", this, "phoneLabel" );
</pre>
<p> In this example, keyboard focus is transferred to the label's
buddy (the <a href="ntqlineedit.html">TQLineEdit</a>) when the user presses Alt+P. You can
also use the <a href="#setBuddy">setBuddy</a>() function to accomplish the same thing.

<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 TQLabel widgets that are not managed by
a <a href="ntqlayout.html">TQLayout</a> (e.g., top-level widgets).

<p> <p>See also <a href="#autoResize">autoResize</a>(), <a href="ntqwidget.html#adjustSize">adjustSize</a>(), and <a href="ntqwidget.html#sizeHint-prop">sizeHint</a>.
<h3 class=fn>void <a name="setBuddy"></a>TQLabel::setBuddy ( <a href="ntqwidget.html">TQWidget</a> * buddy )<tt> [virtual]</tt>
</h3>
Sets this label's buddy to <em>buddy</em>.
<p> When the user presses the accelerator key indicated by this label,
the <a href="focus.html#keyboard-focus">keyboard focus</a> is transferred to the label's buddy widget.
<p> The buddy mechanism is only available for TQLabels that contain
plain text in which one letter is prefixed with an ampersand, &.
This letter is set as the accelerator key. The letter is displayed
underlined, and the '&' is not displayed (i.e. the <a href="ntqt.html#TextFlags-enum">ShowPrefix</a>
alignment flag is turned on; see <a href="#setAlignment">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"), for example:
<pre>
<a href="ntqlineedit.html">TQLineEdit</a> *nameEd = new <a href="ntqlineedit.html">TQLineEdit</a>( this );
TQLabel *nameLb = new TQLabel( "&Name:", this );
nameLb-><a href="#setBuddy">setBuddy</a>( nameEd );
<a href="ntqlineedit.html">TQLineEdit</a> *phoneEd = new <a href="ntqlineedit.html">TQLineEdit</a>( this );
TQLabel *phoneLb = new TQLabel( "&Phone:", this );
phoneLb-><a href="#setBuddy">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> <p>See also <a href="#buddy">buddy</a>(), <a href="#text-prop">text</a>, <a href="ntqaccel.html">TQAccel</a>, and <a href="#alignment-prop">alignment</a>.
<p>Examples: <a href="addressbook-example.html#x580">addressbook/centralwidget.cpp</a>, <a href="tutorial2-09.html#x2642">chart/optionsform.cpp</a>, and <a href="regexptester-example.html#x2482">regexptester/regexptester.cpp</a>.
<h3 class=fn>void <a name="setFont"></a>TQLabel::setFont ( const <a href="ntqfont.html">TQFont</a> & f )<tt> [virtual]</tt>
</h3>
Sets the font used on the TQLabel to font <em>f</em>.
<p>Example: <a href="menu-example.html#x1865">menu/menu.cpp</a>.
<p>Reimplemented from <a href="ntqwidget.html#setFont">TQWidget</a>.

<hr><h2>Property Documentation</h2>
<h3 class=fn>Alignment <a name="alignment-prop"></a>alignment</h3>
<p>This property holds the alignment of the label's contents.
<p>The alignment is a bitwise OR of <a href="ntqt.html#AlignmentFlags-enum">TQt::AlignmentFlags</a> and <a href="ntqt.html#TextFlags-enum">TQt::TextFlags</a> values. The <a href="ntqt.html#TextFlags-enum">ExpandTabs</a>, <a href="ntqt.html#TextFlags-enum">SingleLine</a> and <a href="ntqt.html#TextFlags-enum">ShowPrefix</a> flags apply only if the label contains plain text;
otherwise they are ignored. The <a href="ntqt.html#TextFlags-enum">DontClip</a> flag is always
ignored. <a href="ntqt.html#TextFlags-enum">WordBreak</a> applies to both rich text and plain text
labels. The <a href="ntqt.html#TextFlags-enum">BreakAnywhere</a> flag is not supported in TQLabel.
<p> If the label has a buddy, the <a href="ntqt.html#TextFlags-enum">ShowPrefix</a> flag is forced to
TRUE.
<p> The default alignment is <tt>AlignAuto | AlignVCenter | ExpandTabs</tt>
if the label doesn't have a buddy and <tt>AlignAuto | AlignVCenter | ExpandTabs | ShowPrefix</tt> if the label has a buddy. If the label
contains rich text, additionally <a href="ntqt.html#TextFlags-enum">WordBreak</a> is turned on.
<p> <p>See also <a href="ntqt.html#AlignmentFlags-enum">TQt::AlignmentFlags</a>, <a href="#setBuddy">setBuddy</a>(), and <a href="#text-prop">text</a>.
<p>Set this property's value with <a href="#setAlignment">setAlignment</a>() and get this property's value with <a href="#alignment">alignment</a>().
<h3 class=fn><a href="ntqt.html#BackgroundMode-enum">BackgroundMode</a> <a name="backgroundMode-prop"></a>backgroundMode</h3>
<p>This property holds the label's background mode.
<p>Get this property with <a href="ntqwidget.html#backgroundMode">backgroundMode</a>().
<p> <p>See also <a href="ntqwidget.html#backgroundMode-prop">TQWidget::backgroundMode</a>.
<p><h3 class=fn>int <a name="indent-prop"></a>indent</h3>
<p>This property holds the label's text indent in pixels.
<p>If a label displays text, the indent applies to the left edge if
<a href="#alignment">alignment</a>() is <a href="ntqt.html#AlignmentFlags-enum">AlignLeft</a>, to the right edge if alignment() is
<a href="ntqt.html#AlignmentFlags-enum">AlignRight</a>, to the top edge if alignment() is <a href="ntqt.html#AlignmentFlags-enum">AlignTop</a>, and
to to the bottom edge if alignment() is <a href="ntqt.html#AlignmentFlags-enum">AlignBottom</a>.
<p> If indent is negative, or if no indent has been set, the label
computes the effective indent as follows: If <a href="ntqframe.html#frameWidth">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="ntqwidget.html#font">font</a>().
<p> <p>See also <a href="#alignment-prop">alignment</a>, <a href="ntqframe.html#frameWidth-prop">frameWidth</a>, and <a href="ntqwidget.html#font-prop">font</a>.
<p>Set this property's value with <a href="#setIndent">setIndent</a>() and get this property's value with <a href="#indent">indent</a>().
<h3 class=fn><a href="ntqpixmap.html">TQPixmap</a> <a name="pixmap-prop"></a>pixmap</h3>
<p>This property holds the label's pixmap.
<p>If no pixmap has been set this will return an invalid pixmap.
<p> Setting the pixmap clears any previous content, and resizes the
label if <a href="#autoResize">TQLabel::autoResize</a>() is TRUE. The buddy accelerator,
if any, is disabled.
<p>Set this property's value with <a href="#setPixmap">setPixmap</a>() and get this property's value with <a href="#pixmap">pixmap</a>().
<h3 class=fn>bool <a name="scaledContents-prop"></a>scaledContents</h3>
<p>This property holds whether the label will scale its contents to fill all available space.
<p>When enabled and the label shows a pixmap, it will scale the
pixmap to fill the available space.
<p> This property's default is FALSE.
<p> <p>See also <a href="#scaledContents-prop">scaledContents</a>.
<p>Set this property's value with <a href="#setScaledContents">setScaledContents</a>() and get this property's value with <a href="#hasScaledContents">hasScaledContents</a>().
<h3 class=fn><a href="ntqstring.html">TQString</a> <a name="text-prop"></a>text</h3>
<p>This property holds the label's text.
<p>If no text has been set this will return an empty string. Setting
the text clears any previous content, unless they are the same.
<p> The text will be interpreted either as a plain text or as a rich
text, depending on the text format setting; see <a href="#setTextFormat">setTextFormat</a>().
The default setting is <a href="ntqt.html#TextFormat-enum">AutoText</a>, i.e. TQLabel will try to
auto-detect the format of the text set.
<p> If the text 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, i.e. those small documents that get their document
specific settings (font, text color, link color) from the label's
palette and font properties. For large documents, use <a href="ntqtextedit.html">TQTextEdit</a>
in read-only mode instead. TQTextEdit will flicker less on resize
and can also provide a scrollbar when necessary.
<p> <p>See also <a href="#textFormat-prop">textFormat</a>, <a href="#setBuddy">setBuddy</a>(), and <a href="#alignment-prop">alignment</a>.
<p>Set this property's value with <a href="#setText">setText</a>() and get this property's value with <a href="#text">text</a>().
<h3 class=fn><a href="ntqt.html#TextFormat-enum">TextFormat</a> <a name="textFormat-prop"></a>textFormat</h3>
<p>This property holds the label's text format.
<p>See the <a href="ntqt.html#TextFormat-enum">TQt::TextFormat</a> enum for an explanation of the possible
options.
<p> The default format is <a href="ntqt.html#TextFormat-enum">AutoText</a>.
<p> <p>See also <a href="#text-prop">text</a>.
<p>Set this property's value with <a href="#setTextFormat">setTextFormat</a>() and get this property's value with <a href="#textFormat">textFormat</a>().
