<div class="textblock"><p>Standard KDE help menu with dialog boxes. </p>
<p>This class provides the standard KDE help menu with the default "about" dialog boxes and help entry.</p>
<p>This class is used in <a class="el" href="classKMainWindow.html" title="KDE top level main window">KMainWindow</a> so normally you don't need to use this class yourself. However, if you need the help menu or any of its dialog boxes in your code that is not subclassed from <a class="el" href="classKMainWindow.html" title="KDE top level main window">KMainWindow</a> you should use this class.</p>
<p>The usage is simple:</p>
<div class="fragment"><pre class="fragment"> mHelpMenu = <span class="keyword">new</span> <a class="code" href="classKHelpMenu.html#a3fb7c0a464a0a0f9e93a9a3fffec5309" title="Constructor.">KHelpMenu</a>( <span class="keyword">this</span>, <someText> );
kmenubar->insertItem(i18n(<span class="stringliteral">"&Help"</span>), mHelpMenu->menu() );
</pre></div><p>or if you just want to open a dialog box:</p>
<div class="fragment"><pre class="fragment"> mHelpMenu = <span class="keyword">new</span> <a class="code" href="classKHelpMenu.html#a3fb7c0a464a0a0f9e93a9a3fffec5309" title="Constructor.">KHelpMenu</a>( <span class="keyword">this</span>, <someText> );
<a class="codeRef" href="qobject.html#connect">connect</a>( <span class="keyword">this</span>, SIGNAL(someSignal()), mHelpMenu,SLOT(mHelpMenu->aboutKDE()));
</pre></div><p>IMPORTANT: The first time you use <a class="el" href="classKHelpMenu.html#acf1d8ab4a20daa07f29f9990103f2d1a" title="Returns a popup menu you can use in the menu bar or where you need it.">KHelpMenu::menu()</a>, a <a class="el" href="classKPopupMenu.html" title="A menu with title items.">KPopupMenu</a> object is allocated. Only one object is created by the class so if you call <a class="el" href="classKHelpMenu.html#acf1d8ab4a20daa07f29f9990103f2d1a" title="Returns a popup menu you can use in the menu bar or where you need it.">KHelpMenu::menu()</a> twice or more, the same pointer is returned. The class will destroy the popupmenu in the destructor so do not delete this pointer yourself.</p>
<p>The <a class="el" href="classKHelpMenu.html" title="Standard KDE help menu with dialog boxes.">KHelpMenu</a> object will be deleted when its parent is destroyed but you can delete it yourself if you want. The code below will always work.</p>
<div class="fragment"><pre class="fragment"> MyClass::~MyClass()
{
<span class="keyword">delete</span> mHelpMenu;
}
</pre></div><p>Using your own "about application" dialog box:</p>
<p>The standard "about application" dialog box is quite simple. If you need a dialog box with more functionality you must design that one yourself. When you want to display the dialog you can choose one of two methods. Common for both is that you must make a help menu object with no text argument If the text is missing the default dialog box will not be displayed:</p>
<p>Example 1 Using showAboutApplication signal (preferred) </p>
<div class="fragment"><pre class="fragment"> <span class="keywordtype">void</span> MyClass::myFunc()
{
..
<a class="code" href="classKHelpMenu.html" title="Standard KDE help menu with dialog boxes.">KHelpMenu</a> *helpMenu = <span class="keyword">new</span> <a class="code" href="classKHelpMenu.html#a3fb7c0a464a0a0f9e93a9a3fffec5309" title="Constructor.">KHelpMenu</a>( <span class="keyword">this</span> );
<a class="codeRef" href="qobject.html#connect">connect</a>( helpMenu, SIGNAL(<a class="code" href="classKHelpMenu.html#a0f328efc671bbd2b1c6308335ec02cf8" title="This signal is emitted from aboutApplication() if no "about application" string has been defined...">showAboutApplication</a>()),
<span class="keyword">this</span>, SLOT(myDialogSlot()));
..
}
<span class="keywordtype">void</span> MyClass::myDialogSlot()
{
<activate your custom dialog>
}
</pre></div><p>Example 2 Old style - connecting directly to the menu entry. </p>
<div class="fragment"><pre class="fragment"> <span class="keywordtype">void</span> MyClass::myFunc()
{
<a class="code" href="classKHelpMenu.html" title="Standard KDE help menu with dialog boxes.">KHelpMenu</a> *helpMenu = <span class="keyword">new</span> <a class="code" href="classKHelpMenu.html#a3fb7c0a464a0a0f9e93a9a3fffec5309" title="Constructor.">KHelpMenu</a>( <span class="keyword">this</span> );
