The default way to do -this is to focus the relevant widget and press Shift+F1. The help -text appears immediately; it goes away as soon as the user does -something else. -<p> (Note that if there is an accelerator for Shift+F1, this mechanism -will not work.) -<p> To add "What's this?" text to a widget you simply call -<a href="#add">TQWhatsThis::add</a>() for the widget. For example, to assign text to a -menu item, call <a href="qmenudata.html#setWhatsThis">TQMenuData::setWhatsThis</a>(); for a global -accelerator key, call <a href="qaccel.html#setWhatsThis">TQAccel::setWhatsThis</a>() and If you're using -actions, use <a href="qaction.html#setWhatsThis">TQAction::setWhatsThis</a>(). -<p> The text can be either rich text or plain text. If you specify a -rich text formatted string, it will be rendered using the default -stylesheet. This makes it possible to embed images. See -<a href="qstylesheet.html#defaultSheet">TQStyleSheet::defaultSheet</a>() for details. -<p> - -<pre> const char * fileOpenText = "<p><img source=\"fileopen\"> " - "Click this button to open a <em>new file</em>. <br>" - "You can also select the <b>Open</b> command " - "from the <b>File</b> menu.</p>"; - <a name="x2104"></a> TQMimeSourceFactory::<a href="qmimesourcefactory.html#defaultFactory">defaultFactory</a>()->setPixmap( "fileopen", - <a name="x2102"></a> fileOpenAction-><a href="qaction.html#iconSet">iconSet</a>().pixmap() ); - <a name="x2103"></a> fileOpenAction-><a href="qaction.html#setWhatsThis">setWhatsThis</a>( fileOpenText ); -</pre> -<p> An alternative way to enter "What's this?" mode is to use the -ready-made tool bar tool button from -<a href="#whatsThisButton">TQWhatsThis::whatsThisButton</a>(). By invoking this context help -button (in the picture below the first one from the right) the -user switches into "What's this?" mode. If they now click on a -widget the appropriate help text is shown. The mode is left when -help is given or when the user presses Esc. -<p> <center><img src="whatsthis.png"></center> -<p> If you are using <a href="qmainwindow.html">TQMainWindow</a> you can also use the -<a href="qmainwindow.html#whatsThis">TQMainWindow::whatsThis</a>() slot to invoke the mode from a menu item. -<p> For more control you can create a dedicated TQWhatsThis object for -a special widget. By subclassing and reimplementing -<a href="#text">TQWhatsThis::text</a>() it is possible to have different help texts, -depending on the position of the mouse click. By reimplementing -<a href="#clicked">TQWhatsThis::clicked</a>() it is possible to have hyperlinks inside the -help texts. -<p> If you wish to control the "What's this?" behavior of a widget -manually see <a href="qwidget.html#customWhatsThis">TQWidget::customWhatsThis</a>(). -<p> The What's This object can be removed using <a href="#remove">TQWhatsThis::remove</a>(), -although this is rarely necessary because it is automatically -removed when the widget is destroyed. -<p> <p>See also <a href="qtooltip.html">TQToolTip</a> and <a href="helpsystem.html">Help System</a>. - -<hr><h2>Member Function Documentation</h2> -<h3 class=fn><a name="TQWhatsThis"></a>TQWhatsThis::TQWhatsThis ( <a href="qwidget.html">TQWidget</a> * widget ) -</h3> -Constructs a dynamic "What's this?" object for <em>widget</em>.
