It is drawn immediately below -the region in a distinctive black-on-yellow combination. -<p> The tip can be any Rich-Text formatted string. -<p> <a href="qtooltipgroup.html">TQToolTipGroup</a> provides a way for tool tips to display another text -elsewhere (most often in a <a href="qstatusbar.html">status bar</a>). -<p> At any point in time, TQToolTip is either dormant or active. In -dormant mode the tips are not shown and in active mode they are. -The mode is global, not particular to any one widget. -<p> TQToolTip switches from dormant to active mode when the user hovers -the mouse on a tip-etquipped region for a second or so and remains -active until the user either clicks a mouse button, presses a key, -lets the mouse hover for five seconds or moves the mouse outside -<em>all</em> tip-etquipped regions for at least a second. -<p> The TQToolTip class can be used in three different ways: -<ol type=1> -<li> Adding a tip to an entire widget. -<li> Adding a tip to a fixed rectangle within a widget. -<li> Adding a tip to a dynamic rectangle within a widget. -</ol> -<p> To add a tip to a widget, call the <em>static</em> function -<a href="#add">TQToolTip::add</a>() with the widget and tip as arguments: -<p> <pre> - TQToolTip::<a href="#add">add</a>( quitButton, "Leave the application" ); - </pre> - -<p> This is the simplest and most common use of TQToolTip. The tip -will be deleted automatically when <em>quitButton</em> is deleted, but -you can remove it yourself, too: -<p> <pre> - TQToolTip::<a href="#remove">remove</a>( quitButton ); - </pre> - -<p> You can also display another text (typically in a <a href="qstatusbar.html">status bar),</a> courtesy of <a href="qtooltipgroup.html">TQToolTipGroup</a>. This example -assumes that <em>grp</em> is a <tt>TQToolTipGroup *</tt> and is already -connected to the appropriate status bar: -<p> <pre> - TQToolTip::<a href="#add">add</a>( quitButton, "Leave the application", grp, - "Leave the application, prompting to save if necessary" ); - TQToolTip::<a href="#add">add</a>( closeButton, "Close this window", grp, - "Close this window, prompting to save if necessary" ); - </pre> - -<p> To add a tip to a fixed rectangle within a widget, call the static -function <a href="#add">TQToolTip::add</a>() with the widget, rectangle and tip as -arguments. (See the <a href="tooltip-example.html">tooltip/tooltip.cpp</a> example.) Again, you -can supply a <tt>TQToolTipGroup *</tt> and another text if you want. -<p> Both of these are one-liners and cover the majority of cases. The -third and most general way to use TQToolTip requires you to -reimplement a pure virtual function to decide whether to pop up a -tool tip. The <a href="tooltip-example.html">tooltip/tooltip.cpp</a> example demonstrates this -too. This mode can be used to implement tips for text that can -move as the user scrolls, for example. -<p> To use TQToolTip like this, you must subclass TQToolTip and -reimplement <a href="#maybeTip">maybeTip</a>(). TQToolTip calls maybeTip() when a tip -should pop up, and maybeTip() decides whether to show a tip. -<p> Tool tips can be globally disabled using -<a href="#setGloballyEnabled">TQToolTip::setGloballyEnabled</a>() or disabled in groups with -<a href="qtooltipgroup.html#setEnabled">TQToolTipGroup::setEnabled</a>(). -<p> You can retrieve the text of a tooltip for a given position within -a widget using <a href="#textFor">textFor</a>(). -<p> The global tooltip font and palette can be set with the static -<a href="#setFont">setFont</a>() and <a href="#setPalette">setPalette</a>() functions respectively. -<p> <p>See also <a href="qstatusbar.html">TQStatusBar</a>, <a href="qwhatsthis.html">TQWhatsThis</a>, <a href="qtooltipgroup.html">TQToolTipGroup</a>, <a href="guibooks.html#fowler">GUI Design Handbook: Tool Tip</a>, and <a href="helpsystem.html">Help System</a>. - -<hr><h2>Member Function Documentation</h2> -<h3 class=fn><a name="TQToolTip"></a>TQToolTip::TQToolTip ( <a href="qwidget.html">TQWidget</a> * widget, <a href="qtooltipgroup.html">TQToolTipGroup</a> * group = 0 ) -</h3> -Constructs a tool tip object.
