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="qstring.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="qpixmap.html">TQPixmap</a> to <a href="#setPixmap">setPixmap</a>(). +<tr bgcolor="#d0d0d0"> <td valign="top">A movie +<td valign="top">Pass a <a href="qmovie.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="qframe.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="qframe.html#setFrameStyle">setFrameStyle</a>( TQFrame::<a href="qframe.html#Shape-enum">Panel</a> | TQFrame::<a href="qframe.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="qaccel.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="qlineedit.html">TQLineEdit</a>* phoneEdit = new <a href="qlineedit.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="qlineedit.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> <img src=qlabel-m.png> <img src=qlabel-w.png> +<p> <p>See also <a href="qlineedit.html">TQLineEdit</a>, <a href="qtextedit.html">TQTextEdit</a>, <a href="qpixmap.html">TQPixmap</a>, <a href="qmovie.html">TQMovie</a>, <a href="guibooks.html#fowler">GUI Design Handbook: Label</a>, <a href="basic.html">Basic Widgets</a>, and <a href="text.html">Text Related Classes</a>. + +<hr><h2>Member Function Documentation</h2> +<h3 class=fn><a name="TQLabel"></a>TQLabel::TQLabel ( <a href="qwidget.html">TQWidget</a> * parent, const char * name = 0, WFlags f = 0 ) +</h3> +Constructs an empty label. +<p> The <em>parent</em>, <em>name</em> and <a href="qt.html#WidgetFlags">widget flag</a> <em>f</em>, arguments are passed +to the <a href="qframe.html">TQFrame</a> constructor. +<p> <p>See also <a href="#alignment-prop">alignment</a>, <a href="qframe.html#setFrameStyle">setFrameStyle</a>(), and <a href="#indent-prop">indent</a>. + +<h3 class=fn><a name="TQLabel-2"></a>TQLabel::TQLabel ( const <a href="qstring.html">TQString</a> & text, <a href="qwidget.html">TQWidget</a> * parent, const char * name = 0, WFlags f = 0 ) +</h3> +Constructs a label that displays the text, <em>text</em>. +<p> The <em>parent</em>, <em>name</em> and <a href="qt.html#WidgetFlags">widget flag</a> <em>f</em>, arguments are passed +to the <a href="qframe.html">TQFrame</a> constructor. +<p> <p>See also <a href="#text-prop">text</a>, <a href="#alignment-prop">alignment</a>, <a href="qframe.html#setFrameStyle">setFrameStyle</a>(), and <a href="#indent-prop">indent</a>. + +<h3 class=fn><a name="TQLabel-3"></a>TQLabel::TQLabel ( <a href="qwidget.html">TQWidget</a> * buddy, const <a href="qstring.html">TQString</a> & text, <a href="qwidget.html">TQWidget</a> * parent, const char * name = 0, WFlags f = 0 ) +</h3> +Constructs a label that displays the text <em>text</em>.
