|
||
|
|
|
||
|
|
|
||
|
|
The QMenuBar class provides a horizontal menu bar.
|
||
|
|
<p>
|
||
|
|
|
||
|
|
<p> A menu bar consists of a list of pull-down menu items. You add
|
||
|
|
menu items with <a href="qmenudata.html#insertItem">insertItem()</a>. For example, asuming that <tt>menubar</tt> is a
|
||
|
|
pointer to a QMenuBar and <tt>filemenu</tt> is a pointer to a
|
||
|
|
<a href="qpopupmenu.html">QPopupMenu</a>, the following statement inserts the menu into the menu
|
||
|
|
bar:
|
||
|
|
<pre>
|
||
|
|
menubar->insertItem( "&File", filemenu );
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
The ampersand in the menu item's text sets Alt+F as a shortcut for
|
||
|
|
this menu. (You can use "&&" to get a real ampersand in the menu
|
||
|
|
bar.)
|
||
|
|
<p> Items are either enabled or disabled. You toggle their state with
|
||
|
|
<a href="qmenudata.html#setItemEnabled">setItemEnabled</a>().
|
||
|
|
<p> There is no need to lay out a menu bar. It automatically sets its
|
||
|
|
own geometry to the top of the parent widget and changes it
|
||
|
|
appropriately whenever the parent is resized.
|
||
|
|
<p>
|
||
|
|
<p> Example of creating a menu bar with menu items (from <a href="menu-example.html">menu/menu.cpp</a>):
|
||
|
|
|
||
|
|
|
||
|
|
<pre> <a href="qpopupmenu.html">QPopupMenu</a> *file = new <a href="qpopupmenu.html">QPopupMenu</a>( this );
|
||
|
|
</pre><pre> file-><a href="qmenudata.html#insertItem">insertItem</a>( p1, "&Open", this, SLOT(open()), CTRL+Key_O );
|
||
|
|
file-><a href="qmenudata.html#insertItem">insertItem</a>( p2, "&New", this, SLOT(news()), CTRL+Key_N );
|
||
|
|
</pre><pre> menu = new QMenuBar( this );
|
||
|
|
</pre><pre> menu-><a href="qmenudata.html#insertItem">insertItem</a>( "&File", file );
|
||
|
|
</pre>
|
||
|
|
<p> In most main window style applications you would use the menuBar()
|
||
|
|
provided in <a href="qmainwindow.html">QMainWindow</a>, adding <a href="qpopupmenu.html">QPopupMenu</a>s to the menu bar
|
||
|
|
and adding <a href="qaction.html">QAction</a>s to the popup menus.
|
||
|
|
<p> Example (from <a href="qaction-application-example.html">action/application.cpp</a>):
|
||
|
|
|
||
|
|
|
||
|
|
<pre> <a href="qpopupmenu.html">QPopupMenu</a> * file = new <a href="qpopupmenu.html">QPopupMenu</a>( this );
|
||
|
|
<a href="qmainwindow.html#menuBar">menuBar</a>()->insertItem( "&File", file );
|
||
|
|
fileNewAction-><a href="qaction.html#addTo">addTo</a>( file );
|
||
|
|
</pre>
|
||
|
|
<p> Menu items can have text and pixmaps (or iconsets), see the
|
||
|
|
various <a href="qmenudata.html#insertItem">insertItem()</a>
|
||
|
|
overloads, as well as separators, see <a href="qmenudata.html#insertSeparator">insertSeparator()</a>. You can
|
||
|
|
also add custom menu items that are derived from
|
||
|
|
<a href="qcustommenuitem.html">QCustomMenuItem</a>.
|
||
|
|
<p> Menu items may be removed with <a href="qmenudata.html#removeItem">removeItem</a>() and enabled or
|
||
|
|
disabled with <a href="qmenudata.html#setItemEnabled">setItemEnabled()</a>.

<p> <h3> QMenuBar on Qt/Mac
|
||
|
|
</h3>
|
||
|
|
<a name="1"></a><p> QMenuBar on Qt/Mac is a wrapper for using the system-wide menubar.
|
||
|
|
If you have multiple menubars in one dialog the outermost menubar
|
||
|
|
(normally inside a widget with <a href="qt.html#WidgetFlags">widget flag</a> <a href="qt.html#WidgetFlags-enum">WType_TopLevel</a>) will
|
||
|
|
be used for the system-wide menubar.
|
||
|
|
<p> Note that arbitrary Qt widgets <em>cannot</em> be inserted into a
|
||
|
|
QMenuBar on the Mac because Qt uses Mac's native menus which don't
|
||
|
|
support this functionality. This limitation does not apply to
|
||
|
|
stand-alone QPopupMenus.
|
||
|
|
<p> Qt/Mac also provides a menubar merging feature to make QMenuBar
|
||
|
|
conform more closely to accepted Mac OS X menubar layout. The
|
||
|
|
merging functionality is based on string matching the title of a
|
||
|
|
<a href="qpopupmenu.html">QPopupMenu</a> entry. These strings are translated (using
|
||
|
|
<a href="qobject.html#tr">QObject::tr</a>()) in the "QMenuBar" context. If an entry is moved its
|
||
|
|
slots will still fire as if it was in the original place. The
|
||
|
|
table below outlines the strings looked for and where the entry is
|
||
|
|
placed if matched:
|
||
|
|
<p> <center><table cellpadding="4" cellspacing="2" border="0">

|
|
<td valign="top">If this entry is not found no About item will appear in
|
||
|
|

|
||
|
|
<tr bgcolor="#d0d0d0"> <td valign="top">config, options, setup, settings or preferences
|
||
|
|
<td valign="top">Application Menu | Preferences
|
||
|
|
<td valign="top">If this entry is not found the Settings item will be disabled
|
||
|
|
<tr bgcolor="#f0f0f0"> <td valign="top">quit or exit
|
||
|
|
<td valign="top">Application Menu | Quit <application name>
|
||
|
|
<td valign="top">If this entry is not found a default Quit item will be
|

separator line at its bottom.
|
||
|
|
<ul>
|
||
|

|
|
and having two looks wrong.
|

good in Windows style, but nowhere else.

id of the selected item.
|
||
|
|
<p> Normally you will connect each menu item to a single slot using
|

|
|
<a href="qmenudata.html#insertItem">QMenuData::insertItem</a>(), but sometimes you will want to connect
|

|
|
several items to a single slot (most often if the user selects
|
||
|
|
from an array). This signal is useful in such cases.
|
||
|
|
<p> <p>See also <a href="#highlighted">highlighted</a>() and <a href="qmenudata.html#insertItem">QMenuData::insertItem</a>().

</h3>
|

|
Returns the height that the menu would resize itself to if its
|

|
|
parent (and hence itself) resized to the given <em>max_width</em>. This
|
||
|
|
can be useful for simple layout tasks in which the height of the
|
||
|
|
menu bar is needed after items have been inserted. See <a href="showimg-example.html">showimg/showimg.cpp</a> for an example of the usage.

<p>Example: <a href="showimg-example.html#x1325">showimg/showimg.cpp</a>.

|
<h3 class=fn>void <a name="hide"></a>QMenuBar::hide ()<tt> [virtual]</tt>
|

|
|
</h3>
|
||
|
|
Reimplements <a href="qwidget.html#hide">QWidget::hide</a>() in order to deselect any selected
|
||
|
|
item, and calls setUpLayout() for the main window.
|
||
|
|
|

|
<p>Example: <a href="grapher-nsplugin-example.html#x2745">grapher/grapher.cpp</a>.

|
|
|

|
|
<p> This signal is emitted when a menu item is highlighted; <em>id</em> is

|
|
the id of the highlighted item.
|

|
|
<p> Normally, you will connect each menu item to a single slot using

The family of <a href="qmenudata.html#insertItem">insertItem</a>() functions inserts menu items into a
|
||
|
|
popup menu or a menu bar.
|
||
|
|
<p> A menu item is usually either a text string or a pixmap, both with
|
||
|
|
an optional icon or keyboard accelerator. For special cases it is
|
||
|
|
also possible to insert custom items (see <a href="qcustommenuitem.html">QCustomMenuItem</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>
|
||
|
|
QMenuBar *mainMenu = new QMenuBar;
|
||
|
|
<a href="qpopupmenu.html">QPopupMenu</a> *fileMenu = new <a href="qpopupmenu.html">QPopupMenu</a>;
|
||
|
|
fileMenu-><a href="qmenudata.html#insertItem">insertItem</a>( "New", myView, SLOT(newFile()), CTRL+Key_N );
|
||
|
|
fileMenu-><a href="qmenudata.html#insertItem">insertItem</a>( "Open", myView, SLOT(open()), CTRL+Key_O );
|
||
|
|
mainMenu-><a href="qmenudata.html#insertItem">insertItem</a>( "File", fileMenu );
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
<p> Not all insert functions take an object/slot parameter or an
|
||
|
|
accelerator key. Use <a href="qmenudata.html#connectItem">connectItem</a>() and <a href="qmenudata.html#setAccel">setAccel</a>() on those items.
|
||
|
|
<p> If you need to translate accelerators, use <a href="qobject.html#tr">tr</a>() with the text and
|
||
|
|
accelerator. (For translations use a string <a href="qkeysequence.html">key
|
||
|
|
sequence</a>.):
|
||
|
|
<pre>
|
||
|
|
fileMenu->insertItem( <a href="qobject.html#tr">tr</a>("Open"), myView, SLOT(open()),
|
||
|
|
<a href="qobject.html#tr">tr</a>("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="qiconset.html">QIconSet</a> parameter to specify the
|
||
|
|
little menu item icon. Note that you can always pass a <a href="qpixmap.html">QPixmap</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 Qt 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 Qt are not application-global,
|
||
|
|
instead they are bound to a certain top-level window. For example,
|
||
|
|
accelerators in <a href="qpopupmenu.html">QPopupMenu</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 <a href="qwidget.html#parentWidget">parentWidget</a>()
|
||
|
|
chain. The menu will then install its accelerator object on that
|
||
|
|
top-level widget. For all other cases use an independent <a href="qaccel.html">QAccel</a>
|
||
|
|
object.
|
||
|
|
<p> <b>Warning:</b> Be careful when passing a literal 0 to <a href="qmenudata.html#insertItem">insertItem</a>()
|
||
|
|
because some C++ compilers choose the wrong overloaded function.
|
||
|
|
Cast the 0 to what you mean, e.g. <tt>(QObject*)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 may be fixed in a future Qt
|
||
|
|
version.

</h3>
|
||
|
|
This is an overloaded member function, provided for convenience. It behaves essentially like the above function.
|
||
|
|
<p> Inserts a menu item that consists of the widget <em>widget</em> with
|
||
|
|
optional id <em>id</em>, and optional <em>index</em> position.
|
||
|
|
<p> Ownership of <em>widget</em> is transferred to the popup menu or to the
|
||
|
|
menu bar.
|
||
|
|
<p> Theoretically, any widget can be inserted into a popup menu. In
|
||
|
|
practice, this only makes sense with certain widgets.
|
||
|
|
<p> If a widget is not focus-enabled (see
|
||
|
|
<a href="qwidget.html#isFocusEnabled">QWidget::isFocusEnabled</a>()), the menu treats it as a separator;
|
||
|
|
this means that the item is not selectable and will never get
|
||
|
|
focus. In this way you can, for example, simply insert a <a href="qlabel.html">QLabel</a> if
|
||
|
|
you need a popup menu with a title.
|
||
|
|
<p> If the widget is focus-enabled it will get focus when the user
|
||
|
|
traverses the popup menu with the arrow keys. If the widget does
|
||
|
|
not accept <tt>ArrowUp</tt> and <tt>ArrowDown</tt> in its key event handler,
|
||
|
|
the focus will move back to the menu when the respective arrow key
|
||
|
|
is hit one more time. This works with a <a href="qlineedit.html">QLineEdit</a>, for example. If
|
||
|
|
the widget accepts the arrow key itself, it must also provide the
|
||
|
|
possibility to put the focus back on the menu again by calling
|
||
|
|
<a href="qwidget.html#focusNextPrevChild">QWidget::focusNextPrevChild</a>(). Futhermore, if the embedded widget
|
||
|
|

Inserts a separator at position <em>index</em>, and returns the <a href="qmenudata.html#menu-identifier">menu identifier</a>

|

|
|
<p> In a popup menu a separator is rendered as a horizontal line. In a
|
||
|
|
<a href="motif-extension.html#Motif">Motif</a> menu bar a separator is spacing, so the rest of the items
|
||
|
|
(normally just "Help") are drawn right-justified. In a Windows
|
||
|
|
menu bar separators are ignored (to comply with the Windows style
|
||
|
|
guidelines).
