<hr><a name="details"></a><h2>Detailed Description</h2>
The TQKeySequence class encapsulates a key sequence as used
by accelerators.
<p>
<p> A key sequence consists of up to four keyboard codes, each
optionally combined with modifiers, e.g. <a href="ntqt.html#Modifier-enum">SHIFT</a>, <a href="ntqt.html#Modifier-enum">CTRL</a>, <a href="ntqt.html#Modifier-enum">ALT</a>, <a href="ntqt.html#Modifier-enum">META</a>, or <a href="ntqt.html#Modifier-enum">UNICODE_ACCEL</a>. For example, <tt>CTRL + Key_P</tt>
might be a sequence used as a shortcut for printing a document.
The key codes are listed in <a href="qnamespace-h.html">ntqnamespace.h</a>. As an alternative,
use <a href="ntqt.html#Modifier-enum">UNICODE_ACCEL</a> with the unicode code point of the character.
For example, <tt>UNICODE_ACCEL + 'A'</tt> gives the same key sequence
as <a href="ntqt.html#Key-enum">Key_A</a>.
<p> Key sequences can be constructed either from an integer key code,
or from a human readable translatable string such as
"Ctrl+X,Alt+Space". A key sequence can be cast to a <a href="tqstring.html">TQString</a> to
obtain a human readable translated version of the sequence.
Translations are done in the "TQAccel" context.
<p> <p>See also <a href="ntqaccel.html">TQAccel</a> and <a href="misc.html">Miscellaneous Classes</a>.
<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="TQKeySequence"></a>TQKeySequence::TQKeySequence ()
</h3>
Constructs an empty key sequence.
<h3 class=fn><a name="TQKeySequence-2"></a>TQKeySequence::TQKeySequence ( const&nbsp;<a href="tqstring.html">TQString</a>&nbsp;&amp;&nbsp;key )
</h3>
Creates a key sequence from the string <em>key</em>. For example
"Ctrl+O" gives CTRL+UNICODE_ACCEL+'O'. The strings "Ctrl",
"Shift", "Alt" and "Meta" are recognized, as well as their
translated equivalents in the "TQAccel" context (using
<a href="tqobject.html#tr">TQObject::tr</a>()).
<p> Multiple key codes (up to four) may be entered by separating them
with commas, e.g. "Alt+X,Ctrl+S,Q".
<p> This contructor is typically used with <a href="tqobject.html#tr">tr</a>(), so that accelerator keys can be replaced in
translations:
<p> <pre>
<a href="ntqpopupmenu.html">TQPopupMenu</a> *file = new <a href="ntqpopupmenu.html">TQPopupMenu</a>( this );
file-&gt;<a href="ntqmenudata.html#insertItem">insertItem</a>( tr("&amp;Open..."), this, TQ_SLOT(open()),
<a href="#TQKeySequence">TQKeySequence</a>( tr("Ctrl+O", "File|Open") ) );
</pre>
<p> Note the <tt>"File|Open"</tt> translator comment. It is by no means
necessary, but it provides some context for the human translator.
<h3 class=fn><a name="TQKeySequence-3"></a>TQKeySequence::TQKeySequence ( int&nbsp;key )
</h3>
Constructs a key sequence that has a single <em>key</em>.
<p> The key codes are listed in <a href="qnamespace-h.html">ntqnamespace.h</a> and can be
combined with modifiers, e.g. with <a href="ntqt.html#Modifier-enum">SHIFT</a>, <a href="ntqt.html#Modifier-enum">CTRL</a>, <a href="ntqt.html#Modifier-enum">ALT</a>, <a href="ntqt.html#Modifier-enum">META</a> or <a href="ntqt.html#Modifier-enum">UNICODE_ACCEL</a>.
<h3 class=fn><a name="TQKeySequence-4"></a>TQKeySequence::TQKeySequence ( int&nbsp;k1, int&nbsp;k2, int&nbsp;k3 = 0, int&nbsp;k4 = 0 )
</h3>
Constructs a key sequence with up to 4 keys <em>k1</em>, <em>k2</em>,
<em>k3</em> and <em>k4</em>.
<p> The key codes are listed in <a href="qnamespace-h.html">ntqnamespace.h</a> and can be
combined with modifiers, e.g. with <a href="ntqt.html#Modifier-enum">SHIFT</a>, <a href="ntqt.html#Modifier-enum">CTRL</a>, <a href="ntqt.html#Modifier-enum">ALT</a>, <a href="ntqt.html#Modifier-enum">META</a> or <a href="ntqt.html#Modifier-enum">UNICODE_ACCEL</a>.
<h3 class=fn><a name="TQKeySequence-5"></a>TQKeySequence::TQKeySequence ( const&nbsp;<a href="ntqkeysequence.html">TQKeySequence</a>&nbsp;&amp;&nbsp;keysequence )
</h3>
Copy constructor. Makes a copy of <em>keysequence</em>.
<h3 class=fn><a name="~TQKeySequence"></a>TQKeySequence::~TQKeySequence ()
</h3>
Destroys the key sequence.
<h3 class=fn>uint <a name="count"></a>TQKeySequence::count () const
</h3>
Returns the number of keys in the key sequence.
The maximum is 4.
<h3 class=fn>bool <a name="isEmpty"></a>TQKeySequence::isEmpty () const
</h3>
Returns TRUE if the key sequence is empty; otherwise returns
FALSE.
<h3 class=fn><a href="ntqt.html#SequenceMatch-enum">TQt::SequenceMatch</a> <a name="matches"></a>TQKeySequence::matches ( const&nbsp;<a href="ntqkeysequence.html">TQKeySequence</a>&nbsp;&amp;&nbsp;seq ) const
</h3>
Matches the sequence with <em>seq</em>. Returns <a href="ntqt.html#SequenceMatch-enum">TQt::Identical</a> if
successful, <a href="ntqt.html#SequenceMatch-enum">TQt::PartialMatch</a> for matching but incomplete <em>seq</em>,
and <a href="ntqt.html#SequenceMatch-enum">TQt::NoMatch</a> if the sequences have nothing in common.
Returns <a href="ntqt.html#SequenceMatch-enum">TQt::NoMatch</a> if <em>seq</em> is shorter.
<h3 class=fn><a name="operator-TQString"></a>TQKeySequence::operator TQString () const
</h3>
Creates an accelerator string for the key sequence.
For instance CTRL+Key_O gives "Ctrl+O". If the key sequence has
multiple key codes they are returned comma-separated, e.g.
"Alt+X, Ctrl+Y, Z". The strings, "Ctrl", "Shift", etc. are
translated (using <a href="tqobject.html#tr">TQObject::tr</a>()) in the "TQAccel" scope. If the key
sequence has no keys, <a href="tqstring.html#TQString-null">TQString::null</a> is returned.
<p> On Mac OS X, the string returned resembles the sequence that is shown in
the menubar.
<h3 class=fn><a name="operator-int"></a>TQKeySequence::operator int () const
</h3>
<b>This function is obsolete.</b> It is provided to keep old source working. We strongly advise against using it in new code.
<p> For backward compatibility: returns the first keycode
as integer. If the key sequence is empty, 0 is returned.
<h3 class=fn>bool <a name="operator!-eq"></a>TQKeySequence::operator!= ( const&nbsp;<a href="ntqkeysequence.html">TQKeySequence</a>&nbsp;&amp;&nbsp;keysequence ) const
</h3>
Returns TRUE if <em>keysequence</em> is not equal to this key sequence;
otherwise returns FALSE.
<h3 class=fn><a href="ntqkeysequence.html">TQKeySequence</a>&nbsp;&amp; <a name="operator-eq"></a>TQKeySequence::operator= ( const&nbsp;<a href="ntqkeysequence.html">TQKeySequence</a>&nbsp;&amp;&nbsp;keysequence )
</h3>
Assignment operator. Assigns <em>keysequence</em> to this
object.
<h3 class=fn>bool <a name="operator-eq-eq"></a>TQKeySequence::operator== ( const&nbsp;<a href="ntqkeysequence.html">TQKeySequence</a>&nbsp;&amp;&nbsp;keysequence ) const
</h3>
Returns TRUE if <em>keysequence</em> is equal to this key
sequence; otherwise returns FALSE.
<h3 class=fn>int <a name="operator[]"></a>TQKeySequence::operator[] ( uint&nbsp;index ) const
</h3>
Returns a reference to the element at position <em>index</em> in the key
sequence. This can only be used to read an element.
