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> +<p>See also <a href="qlineedit.html">QLineEdit</a>, <a href="qtextview.html">QTextView</a>, <a href="qpixmap.html">QPixmap</a>, <a href="qmovie.html">QMovie</a> and <a href="guibooks.html#fowler">GUI Design Handbook: Label</a> +<p>Examples: + <a href="cursor-cursor-cpp.html#QLabel">cursor/cursor.cpp</a> + <a href="layout-layout-cpp.html#QLabel">layout/layout.cpp</a> + <a href="popup-popup-cpp.html#QLabel">popup/popup.cpp</a> + <a href="menu-menu-cpp.html#QLabel">menu/menu.cpp</a> + <a href="progress-progress-cpp.html#QLabel">progress/progress.cpp</a> + <a href="qmag-qmag-cpp.html#QLabel">qmag/qmag.cpp</a> + <a href="movies-main-cpp.html#QLabel">movies/main.cpp</a> + <a href="customlayout-main-cpp.html#QLabel">customlayout/main.cpp</a> + +<hr><h2>Member Function Documentation</h2> +<h3 class="fn"><a name="5514c7"></a>QLabel::QLabel(<a href="qwidget.html">QWidget</a>*buddy, const<a href="qstring.html">QString</a>&text, <a href="qwidget.html">QWidget</a>*parent, constchar*name=0, WFlagsf=0)</h3> +<p>Constructs a label with a text and a buddy. +<p>The <em>text</em> is set with <a href="#dffb43">setText</a>().
