it draws the tabs using one of +the predefined <a href="#Shape-enum">shapes</a>, and emits a +signal when a tab is selected. It can be subclassed to tailor the +look and feel. TQt also provides a ready-made <a href="ntqtabwidget.html">TQTabWidget</a> and a +<a href="ntqtabdialog.html">TQTabDialog</a>. +<p> The choice of tab shape is a matter of taste, although tab dialogs +(for preferences and similar) invariably use <a href="#Shape-enum">RoundedAbove</a>; +nobody uses <a href="#Shape-enum">TriangularAbove</a>. Tab controls in windows other than +dialogs almost always use either <a href="#Shape-enum">RoundedBelow</a> or <a href="#Shape-enum">TriangularBelow</a>. Many spreadsheets and other tab controls in which +all the pages are essentially similar use <a href="#Shape-enum">TriangularBelow</a>, +whereas <a href="#Shape-enum">RoundedBelow</a> is used mostly when the pages are +different (e.g. a multi-page tool palette). +<p> The most important part of TQTabBar's API is the <a href="#selected">selected</a>() signal. +This is emitted whenever the selected page changes (even at +startup, when the selected page changes from 'none'). There is +also a slot, <a href="#setCurrentTab">setCurrentTab</a>(), which can be used to select a page +programmatically. +<p> TQTabBar creates automatic accelerator keys in the manner of +<a href="ntqbutton.html">TQButton</a>; e.g. if a tab's label is "&Graphics", Alt+G becomes an +accelerator key for switching to that tab. +<p> The following virtual functions may need to be reimplemented: +<ul> +<li> <a href="#paint">paint</a>() paints a single tab. <a href="#paintEvent">paintEvent</a>() calls paint() for +each tab so that any overlap will look right. +<li> <a href="#addTab">addTab</a>() creates a new tab and adds it to the bar. +<li> <a href="#selectTab">selectTab</a>() decides which tab, if any, the user selects with the mouse. +</ul> +<p> The index of the current tab is returned by <a href="#currentTab">currentTab</a>(). The tab +with a particular index is returned by <a href="#tabAt">tabAt</a>(), the tab with a +particular id is returned by <a href="#tab">tab</a>(). The index of a tab is returned +by <a href="#indexOf">indexOf</a>(). The current tab can be set by index or tab pointer +using one of the <a href="#setCurrentTab">setCurrentTab</a>() functions. +<p> <img src=qtabbar-m.png> <img src=qtabbar-w.png> +<p>See also <a href="advanced.html">Advanced Widgets</a>. + +<hr><h2>Member Type Documentation</h2> +<h3 class=fn><a name="Shape-enum"></a>TQTabBar::Shape</h3> + +<p> This enum type lists the built-in shapes supported by TQTabBar: +<ul> +<li><tt>TQTabBar::RoundedAbove</tt> - the normal rounded look above the pages +<li><tt>TQTabBar::RoundedBelow</tt> - the normal rounded look below the pages +<li><tt>TQTabBar::TriangularAbove</tt> - triangular tabs above the pages (very +unusual; included for completeness) +<li><tt>TQTabBar::TriangularBelow</tt> - triangular tabs similar to those used in +the Excel spreadsheet, for example +</ul> +<hr><h2>Member Function Documentation</h2> +<h3 class=fn><a name="TQTabBar"></a>TQTabBar::TQTabBar ( <a href="ntqwidget.html">TQWidget</a> * parent = 0, const char * name = 0 ) +</h3> +Constructs a new, empty tab bar; the <em>parent</em> and <em>name</em> +arguments are passed on to the <a href="ntqwidget.html">TQWidget</a> constructor. + +<h3 class=fn><a name="~TQTabBar"></a>TQTabBar::~TQTabBar () +</h3> +Destroys the tab control, freeing memory used. + +<h3 class=fn>int <a name="addTab"></a>TQTabBar::addTab ( <a href="qtab.html">TQTab</a> * newTab )<tt> [virtual]</tt> +</h3> +Adds the tab, <em>newTab</em>, to the tab control. +<p> Sets <em>newTab</em>'s id to a new id and places the tab just to the +right of the existing tabs.
