class for <a href="tqmenubar.html">TQMenuBar</a> and <a href="tqpopupmenu.html">TQPopupMenu</a>. +<p> +<p> TQMenuData has an internal list of menu items. A menu item can have +a <a href="#text">text</a>(), an <a href="#accel">accelerator</a>, a <a href="#pixmap">pixmap</a>(), an +<a href="#iconSet">iconSet</a>(), a <a href="#whatsThis">whatsThis</a>() text and a popup menu (unless it is a +separator). Menu items may optionally be <a href="#setItemChecked">checked</a> (except for separators). +<p> The menu item sends out an <a href="tqmenubar.html#activated">activated()</a> signal when it is chosen and a <a href="tqmenubar.html#highlighted">highlighted()</a> signal when it +receives the user input focus. +<p> <!-- index menu identifier --><a name="menu-identifier"></a> +<p> Menu items are assigned the menu identifier <em>id</em> that is passed +in <a href="#insertItem">insertItem</a>() or an automatically generated identifier if <em>id</em> +is < 0 (the default). The generated identifiers (negative +integers) are guaranteed to be unique within the entire +application. The identifier is used to access the menu item in +other functions. +<p> Menu items can be removed with <a href="#removeItem">removeItem</a>() and <a href="#removeItemAt">removeItemAt</a>(), or +changed with <a href="#changeItem">changeItem</a>(). All menu items can be removed with +<a href="#clear">clear</a>(). Accelerators can be changed or set with <a href="#setAccel">setAccel</a>(). +Checkable items can be checked or unchecked with <a href="#setItemChecked">setItemChecked</a>(). +Items can be enabled or disabled using <a href="#setItemEnabled">setItemEnabled</a>() and +connected and disconnected with <a href="#connectItem">connectItem</a>() and <a href="#disconnectItem">disconnectItem</a>() +respectively. By default, newly created menu items are visible. +They can be hidden (and shown again) with <a href="#setItemVisible">setItemVisible</a>(). +<p> Menu items are stored in a list. Use <a href="#findItem">findItem</a>() to find an item by +its list position or by its menu identifier.

For special cases it is +also possible to insert custom items (see <a href="qcustommenuitem.html">TQCustomMenuItem</a>) or +even widgets into popup menus. +<p> Some insertItem() members take a popup menu as an additional +argument. Use this to insert submenus into existing menus or +pulldown menus into a menu bar. +<p> The number of insert functions may look confusing, but they are +actually quite simple to use. +<p> This default version inserts a menu item with the text <em>text</em>, +the accelerator key <em>accel</em>, an id and an optional index and +connects it to the slot <em>member</em> in the object <em>receiver</em>. +<p> Example: +<pre> + <a href="tqmenubar.html">TQMenuBar</a> *mainMenu = new <a href="tqmenubar.html">TQMenuBar</a>; + <a href="tqpopupmenu.html">TQPopupMenu</a> *fileMenu = new <a href="tqpopupmenu.html">TQPopupMenu</a>; + fileMenu-><a href="#insertItem">insertItem</a>( "New", myView, TQ_SLOT(newFile()), CTRL+Key_N ); + fileMenu-><a href="#insertItem">insertItem</a>( "Open", myView, TQ_SLOT(open()), CTRL+Key_O ); + mainMenu-><a href="#insertItem">insertItem</a>( "File", fileMenu ); + </pre> + +<p> Not all insert functions take an object/slot parameter or an +accelerator key. Use <a href="#connectItem">connectItem</a>() and <a href="#setAccel">setAccel</a>() on those items. +<p> If you need to translate accelerators, use tr() with the text and +accelerator. (For translations use a string <a href="ntqkeysequence.html">key + sequence</a>.): +<pre> + fileMenu->insertItem( tr("Open"), myView, TQ_SLOT(open()), + tr("Ctrl+O") ); + </pre> + +<p> In the example above, pressing Ctrl+O or selecting "Open" from the +menu activates the myView->open() function. +<p> Some insert functions take a <a href="tqiconset.html">TQIconSet</a> parameter to specify the +little menu item icon. Note that you can always pass a <a href="ntqpixmap.html">TQPixmap</a> +object instead. +<p> The <em>id</em> specifies the identification number associated with the +menu item. Note that only positive values are valid, as a negative +value will make TQt select a unique id for the item. +<p> The <em>index</em> specifies the position in the menu. The menu item is +appended at the end of the list if <em>index</em> is negative. +<p> Note that keyboard accelerators in TQt are not application-global, +instead they are bound to a certain top-level window. For example, +accelerators in <a href="tqpopupmenu.html">TQPopupMenu</a> items only work for menus that are +associated with a certain window. This is true for popup menus +that live in a menu bar since their accelerators will then be +installed in the menu bar itself. This also applies to stand-alone +popup menus that have a top-level widget in their parentWidget() +chain. The menu will then install its accelerator object on that +top-level widget. For all other cases use an independent <a href="ntqaccel.html">TQAccel</a> +object. +<p> <b>Warning:</b> Be careful when passing a literal 0 to <a href="#insertItem">insertItem</a>() +because some C++ compilers choose the wrong overloaded function. +Cast the 0 to what you mean, e.g. <tt>(TQObject*)0</tt>. +<p> <b>Warning:</b> On Mac OS X, items that connect to a slot that are inserted into a +menubar will not function as we use the native menubar that knows nothing +about signals or slots. Instead insert the items into a popup menu and +insert the popup menu into the menubar.

This also applies to stand-alone +popup menus that have a top-level widget in their parentWidget() +chain. The menu will then install its accelerator object on that +top-level widget. For all other cases use an independent <a href="ntqaccel.html">TQAccel</a> +object. +<p> Example: +<pre> + <a href="tqmenubar.html">TQMenuBar</a> *mainMenu = new <a href="tqmenubar.html">TQMenuBar</a>; + <a href="tqpopupmenu.html">TQPopupMenu</a> *fileMenu = new <a href="tqpopupmenu.html">TQPopupMenu</a>; // file sub menu + fileMenu-><a href="#insertItem">insertItem</a>( "Open Document", 67 ); // add "Open" item + fileMenu-><a href="#setAccel">setAccel</a>( CTRL + Key_O, 67 ); // Ctrl+O to open + fileMenu-><a href="#insertItem">insertItem</a>( "Quit", 69 ); // add "Quit" item + fileMenu-><a href="#setAccel">setAccel</a>( CTRL + ALT + Key_Delete, 69 ); // add Alt+Del to quit + mainMenu-><a href="#insertItem">insertItem</a>( "File", fileMenu ); // add the file menu + </pre> + +<p> If you need to translate accelerators, use tr() with a string: +<pre> + fileMenu->setAccel( tr("Ctrl+O"), 67 ); + </pre> + +<p> You can also specify the accelerator in the <a href="#insertItem">insertItem</a>() function. +You may prefer to use <a href="tqaction.html">TQAction</a> to associate accelerators with menu +items. +<p> <p>See also <a href="#accel">accel</a>(), <a href="#insertItem">insertItem</a>(), <a href="ntqaccel.html">TQAccel</a>, and <a href="tqaction.html">TQAction</a>. + +<p>Example: <a href="menu-example.html#x1871">menu/menu.cpp</a>. +<h3 class=fn>void <a name="setId"></a>TQMenuData::setId ( int index, int id )<tt> [virtual]</tt> +</h3> +Sets the <a href="tqmenudata.html#menu-identifier">menu identifier</a> of the item at <em>index</em> to <em>id</em>. +<p> If <em>index</em> is out of range, the operation is ignored. +<p> <p>See also <a href="#idAt">idAt</a>(). + +<h3 class=fn>void <a name="setItemChecked"></a>TQMenuData::setItemChecked ( int id, bool check ) +</h3> +If <em>check</em> is TRUE, checks the menu item with id <em>id</em>; otherwise +unchecks the menu item with id <em>id</em>.
