<!-- $$$QTabBar-description -->
<div class="descr">
<h2>Detailed Description</h2>
<p>The QTabBar class provides a tab bar, e.g. for use in tabbed dialogs.</p>
<p>QTabBar is straightforward to use; it draws the tabs using one of the predefined <a href="qtabbar.html#Shape-enum">shapes</a>, and emits a signal when a tab is selected. It can be subclassed to tailor the look and feel. Qt also provides a ready-made <a href="qtabwidget.html">QTabWidget</a>.</p>
<p>Each tab has a <a href="qtabbar.html#tabText">tabText</a>(), an optional <a href="qtabbar.html#tabIcon">tabIcon</a>(), an optional <a href="qtabbar.html#tabToolTip">tabToolTip</a>(), optional <a href="qtabbar.html#tabWhatsThis">tabWhatsThis</a>() and optional <a href="qtabbar.html#tabData">tabData</a>(). The tabs's attributes can be changed with <a href="qtabbar.html#setTabText">setTabText</a>(), <a href="qtabbar.html#setTabIcon">setTabIcon</a>(), <a href="qtabbar.html#setTabToolTip">setTabToolTip</a>(), setTabWhatsThis and <a href="qtabbar.html#setTabData">setTabData</a>(). Each tabs can be enabled or disabled individually with <a href="qtabbar.html#setTabEnabled">setTabEnabled</a>().</p>
<p>Each tab can display text in a distinct color. The current text color for a tab can be found with the <a href="qtabbar.html#tabTextColor">tabTextColor</a>() function. Set the text color for a particular tab with <a href="qtabbar.html#setTabTextColor">setTabTextColor</a>().</p>
<p>Tabs are added using <a href="qtabbar.html#addTab">addTab</a>(), or inserted at particular positions using <a href="qtabbar.html#insertTab">insertTab</a>(). The total number of tabs is given by <a href="qtabbar.html#count-prop">count</a>(). Tabs can be removed from the tab bar with <a href="qtabbar.html#removeTab">removeTab</a>(). Combining <a href="qtabbar.html#removeTab">removeTab</a>() and <a href="qtabbar.html#insertTab">insertTab</a>() allows you to move tabs to different positions.</p>
<p>The <a href="qtabbar.html#shape-prop">shape</a> property defines the tabs' appearance. The choice of shape is a matter of taste, although tab dialogs (for preferences and similar) invariably use <a href="qtabbar.html#Shape-enum">RoundedNorth</a>. Tab controls in windows other than dialogs almost always use either <a href="qtabbar.html#Shape-enum">RoundedSouth</a> or <a href="qtabbar.html#Shape-enum">TriangularSouth</a>. Many spreadsheets and other tab controls in which all the pages are essentially similar use <a href="qtabbar.html#Shape-enum">TriangularSouth</a>, whereas <a href="qtabbar.html#Shape-enum">RoundedSouth</a> is used mostly when the pages are different (e.g. a multi-page tool palette). The default in QTabBar is <a href="qtabbar.html#Shape-enum">RoundedNorth</a>.</p>
<p>The most important part of QTabBar's API is the <a href="qtabbar.html#currentChanged">currentChanged</a>() signal. This is emitted whenever the current tab changes (even at startup, when the current tab changes from 'none'). There is also a slot, <a href="qtabbar.html#currentIndex-prop">setCurrentIndex</a>(), which can be used to select a tab programmatically. The function <a href="qtabbar.html#currentIndex-prop">currentIndex</a>() returns the index of the current tab, <a href="qtabbar.html#count-prop">count</a> holds the number of tabs.</p>
<p>QTabBar creates automatic mnemonic keys in the manner of <a href="qabstractbutton.html">QAbstractButton</a>; e.g. if a tab's label is "&Graphics", Alt+G becomes a shortcut key for switching to that tab.</p>
<p>The following virtual functions may need to be reimplemented in order to tailor the look and feel or store extra data with each tab:</p>
<ul>
<li><a href="qtabbar.html#tabSizeHint">tabSizeHint</a>() calcuates the size of a tab.</li>
<li><a href="qtabbar.html#tabInserted">tabInserted</a>() notifies that a new tab was added.</li>
<li><a href="qtabbar.html#tabRemoved">tabRemoved</a>() notifies that a tab was removed.</li>
<li><a href="qtabbar.html#tabLayoutChange">tabLayoutChange</a>() notifies that the tabs have been re-laid out.</li>
<li><a href="qtabbar.html#paintEvent">paintEvent</a>() paints all tabs.</li>
</ul>
<p>For subclasses, you might also need the <a href="qtabbar.html#tabRect">tabRect</a>() functions which returns the visual geometry of a single tab.</p>

<h3 class="fn"><a name="usesScrollButtons-prop"></a><span class="name">usesScrollButtons</span> : <span class="type">bool</span></h3>
<p>This property holds whether or not a tab bar should use buttons to scroll tabs when it has many tabs.</p>
<p>When there are too many tabs in a tab bar for its size, the tab bar can either choose to expand its size or to add buttons that allow you to scroll through the tabs.</p>
<p>By default the value is style dependant.</p>
<p>This property was introduced in Qt 4.2.</p>
