|
|
|
|
|
|
The TQMenuData class is a base class for <a href="ntqmenubar.html">TQMenuBar</a> and <a href="ntqpopupmenu.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="ntqmenubar.html#activated">activated()</a> signal when it is chosen and a <a href="ntqmenubar.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. (See also <a href="#indexOf">indexOf</a>()
|
|
and <a href="#idAt">idAt</a>().)
|
|
<p> <p>See also <a href="ntqaccel.html">TQAccel</a>, <a href="ntqpopupmenu.html">TQPopupMenu</a>, <a href="ntqaction.html">TQAction</a>, and <a href="misc.html">Miscellaneous Classes</a>.

</h3>
|
|
The family of <a href="#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">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="ntqmenubar.html">TQMenuBar</a> *mainMenu = new <a href="ntqmenubar.html">TQMenuBar</a>;
|
|
<a href="ntqpopupmenu.html">TQPopupMenu</a> *fileMenu = new <a href="ntqpopupmenu.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="ntqpopupmenu.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 may be fixed in a future TQt
|
|
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="tqwidget.html#isFocusEnabled">TQWidget::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="ntqlabel.html">TQLabel</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="ntqlineedit.html">TQLineEdit</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="tqwidget.html#focusNextPrevChild">TQWidget::focusNextPrevChild</a>(). Futhermore, if the embedded widget
|
|
closes the menu when the user made a selection, this can be done

safely by calling:

<h3 class=fn>void <a name="setAccel"></a>TQMenuData::setAccel ( const <a href="ntqkeysequence.html">TQKeySequence</a> & key, int id )
|
|
</h3>
|
|
Sets the accelerator key for the menu item <em>id</em> to <em>key</em>.
|
|
<p> An accelerator key consists of a key code and a combination of the
|
|
modifiers <tt>SHIFT</tt>, <tt>CTRL</tt>, <tt>ALT</tt> or <tt>UNICODE_ACCEL</tt> (OR'ed or
|
|
added). The header file <a href="qnamespace-h.html">ntqnamespace.h</a> contains a list of key
|
|
codes.
|
|
<p> Defining an accelerator key produces a text that is added to the
|
|
menu item; for instance, <tt>CTRL</tt> + <tt>Key_O</tt> produces "Ctrl+O". The
|
|
text is formatted differently for different platforms.
|
|
<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="ntqpopupmenu.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> Example:
|
|
<pre>
|
|
<a href="ntqmenubar.html">TQMenuBar</a> *mainMenu = new <a href="ntqmenubar.html">TQMenuBar</a>;
|
|
<a href="ntqpopupmenu.html">TQPopupMenu</a> *fileMenu = new <a href="ntqpopupmenu.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="ntqaction.html">TQAction</a> to associate accelerators with menu
|
|
items.
|
|
