<!-- $$$QStatusBar-description -->
<div class="descr">
<h2>Detailed Description</h2>
<p>The QStatusBar class provides a horizontal bar suitable for presenting status information.</p>
<p>Each status indicator falls into one of three categories:</p>
<ul>
<li><i>Temporary</i> - briefly occupies most of the status bar. Used to explain tool tip texts or menu entries, for example.</li>
<li><i>Normal</i> - occupies part of the status bar and may be hidden by temporary messages. Used to display the page and line number in a word processor, for example.</li>
<li><i>Permanent</i> - is never hidden. Used for important mode indications, for example, some applications put a Caps Lock indicator in the status bar.</li>
</ul>
<p>QStatusBar lets you display all three types of indicators.</p>
<p>Typically, a request for the status bar functionality occurs in relation to a <a href="qmainwindow.html">QMainWindow</a> object. <a href="qmainwindow.html">QMainWindow</a> provides a main application window, with a menu bar, tool bars, dock widgets <i>and</i> a status bar around a large central widget. The status bar can be retrieved using the <a href="qmainwindow.html#statusBar">QMainWindow::statusBar</a>() function, and replaced using the <a href="qmainwindow.html#setStatusBar">QMainWindow::setStatusBar</a>() function.</p>
<p>Use the <a href="qstatusbar.html#showMessage">showMessage</a>() slot to display a <i>temporary</i> message:</p>
<pre class="cpp"> <span class="type">void</span> MainWindow<span class="operator">::</span>createStatusBar()
{
statusBar()<span class="operator">-</span><span class="operator">&gt;</span>showMessage(tr(<span class="string">&quot;Ready&quot;</span>));
}</pre>
<p>To remove a temporary message, use the <a href="qstatusbar.html#clearMessage">clearMessage</a>() slot, or set a time limit when calling <a href="qstatusbar.html#showMessage">showMessage</a>(). For example:</p>
<pre class="cpp"> <span class="type">void</span> MainWindow<span class="operator">::</span>print()
{
<span class="preprocessor">#ifndef QT_NO_PRINTDIALOG</span>
<span class="type"><a href="qtextdocument.html">QTextDocument</a></span> <span class="operator">*</span>document <span class="operator">=</span> textEdit<span class="operator">-</span><span class="operator">&gt;</span>document();
<span class="type"><a href="qprinter.html">QPrinter</a></span> printer;
<span class="type"><a href="qprintdialog.html">QPrintDialog</a></span> <span class="operator">*</span>dlg <span class="operator">=</span> <span class="keyword">new</span> <span class="type"><a href="qprintdialog.html">QPrintDialog</a></span>(<span class="operator">&amp;</span>printer<span class="operator">,</span> <span class="keyword">this</span>);
<span class="keyword">if</span> (dlg<span class="operator">-</span><span class="operator">&gt;</span>exec() <span class="operator">!</span><span class="operator">=</span> <span class="type"><a href="qdialog.html">QDialog</a></span><span class="operator">::</span>Accepted)
<span class="keyword">return</span>;
document<span class="operator">-</span><span class="operator">&gt;</span>print(<span class="operator">&amp;</span>printer);
statusBar()<span class="operator">-</span><span class="operator">&gt;</span>showMessage(tr(<span class="string">&quot;Ready&quot;</span>)<span class="operator">,</span> <span class="number">2000</span>);
<span class="preprocessor">#endif</span>
}</pre>
<p>Use the <a href="qstatusbar.html#currentMessage">currentMessage</a>() function to retrieve the temporary message currently shown. The QStatusBar class also provide the <a href="qstatusbar.html#messageChanged">messageChanged</a>() signal which is emitted whenever the temporary status message changes.</p>
<a name="permanent-message"></a><p><i>Normal</i> and <i>Permanent</i> messages are displayed by creating a small widget (<a href="qlabel.html">QLabel</a>, <a href="qprogressbar.html">QProgressBar</a> or even <a href="qtoolbutton.html">QToolButton</a>) and then adding it to the status bar using the <a href="qstatusbar.html#addWidget">addWidget</a>() or the <a href="qstatusbar.html#addPermanentWidget">addPermanentWidget</a>() function. Use the <a href="qstatusbar.html#removeWidget">removeWidget</a>() function to remove such messages from the status bar.</p>
<pre class="cpp"> statusBar()<span class="operator">-</span><span class="operator">&gt;</span><a href="qstatusbar.html#addWidget">addWidget</a>(<span class="keyword">new</span> MyReadWriteIndication);</pre>
<p>By default QStatusBar provides a <a href="qsizegrip.html">QSizeGrip</a> in the lower-right corner. You can disable it using the <a href="qstatusbar.html#sizeGripEnabled-prop">setSizeGripEnabled</a>() function. Use the <a href="qstatusbar.html#sizeGripEnabled-prop">isSizeGripEnabled</a>() function to determine the current status of the size grip.</p>

<p>Inserts the given <i>widget</i> at the given <i>index</i> permanently to this status bar, reparenting the widget if it isn't already a child of this <a href="qstatusbar.html">QStatusBar</a> object. If <i>index</i> is out of range, the widget is appended (in which case it is the actual index of the widget that is returned).</p>
<p>The <i>stretch</i> parameter is used to compute a suitable size for the given <i>widget</i> as the status bar grows and shrinks. The default stretch factor is 0, i.e giving the widget a minimum of space.</p>
<p>Permanently means that the widget may not be obscured by temporary messages. It is is located at the far right of the status bar.</p>
<p>This function was introduced in Qt 4.2.</p>

<p>Removes the specified <i>widget</i> from the status bar.</p>
<p><b>Note:</b> This function does not delete the widget but <i>hides</i> it. To add the widget again, you must call both the <a href="qstatusbar.html#addWidget">addWidget</a>() and <a href="qwidget.html#show">show</a>() functions.</p>

<p>Hides the normal status indications and displays the given <i>message</i> for the specified number of milli-seconds (<i>timeout</i>). If <i>timeout</i> is 0 (default), the <i>message</i> remains displayed until the <a href="qstatusbar.html#clearMessage">clearMessage</a>() slot is called or until the showMessage() slot is called again to change the message.</p>
<p>Note that showMessage() is called to show temporary explanations of tool tip texts, so passing a <i>timeout</i> of 0 is not sufficient to display a <a href="qstatusbar.html#permanent-message">permanent message</a>.</p>
