QToolTipGroup provides a way to linktool tips to this status bar.<p> QToolTipGroup has practically no API; it is used only as an argumentto <a href="qtooltip.html">QToolTip</a>'s member functions, for example like this:<p> <pre> QToolTipGroup * g = new QToolTipGroup( this, "tool tip relay" ); <a href="qobject.html#connect">connect</a>( g, SIGNAL(<a href="#showTip">showTip</a>(const <a href="qstring.html">QString</a>&)), myLabel, SLOT(setText(const <a href="qstring.html">QString</a>&)) ); <a href="qobject.html#connect">connect</a>( g, SIGNAL(<a href="#removeTip">removeTip</a>()), myLabel, SLOT(clear()) ); QToolTip::<a href="qtooltip.html#add">add</a>( giraffeButton, "feed giraffe", g, "Give the giraffe a meal" ); QToolTip::<a href="qtooltip.html#add">add</a>( gorillaButton, "feed gorilla", g, "Give the gorilla a meal" ); </pre> <p> This example makes the object myLabel (which you have to supply)display (one assumes, though you can make myLabel do anything, ofcourse) the strings "Give the giraffe a meal" and "Give the gorillaa meal" while the relevant tool tips are being displayed.<p> Deleting a tool tip group removes the tool tips in it.<p>See also <a href="helpsystem.html">Help System</a>.<hr><h2>Member Function Documentation</h2><h3 class=fn><a name="QToolTipGroup"></a>QToolTipGroup::QToolTipGroup ( <a href="qobject.html">QObject</a> * parent, const char * name = 0 )</h3>Constructs a tool tip group with parent <em>parent</em> and name <em>name</em>.<h3 class=fn><a name="~QToolTipGroup"></a>QToolTipGroup::~QToolTipGroup ()</h3>Destroys this tool tip group and all tool tips in it.<h3 class=fn>bool <a name="delay"></a>QToolTipGroup::delay () const</h3><p>Returns TRUE if the display of the group text is delayed; otherwise returns FALSE.See the <a href="qtooltipgroup.html#delay-prop">"delay"</a> property for details.<h3 class=fn>bool <a name="enabled"></a>QToolTipGroup::enabled () const</h3><p>Returns TRUE if tool tips in the group are enabled; otherwise returns FALSE.See the <a href="qtooltipgroup.html#enabled-prop">"enabled"</a> property for details.<h3 class=fn>void <a name="removeTip"></a>QToolTipGroup::removeTip ()<tt> [signal]</tt></h3> <p> This signal is emitted when a tool tip in this group is hidden.
