.SH DESCRIPTION
The QKeySequence class encapsulates a key sequence as used by accelerators.
.PP
A key sequence consists of up to four keyboard codes, each optionally combined with modifiers, e.g. SHIFT, CTRL, ALT, META, or UNICODE_ACCEL. For example, \fCCTRL + Key_P\fR might be a sequence used as a shortcut for printing a document. The key codes are listed in ntqnamespace.h. As an alternative, use UNICODE_ACCEL with the unicode code point of the character. For example, \fCUNICODE_ACCEL + 'A'\fR gives the same key sequence as Key_A.
.PP
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 TQString to obtain a human readable translated version of the sequence. Translations are done in the "QAccel" context.
.PP
See also QAccel and Miscellaneous Classes.
.SH MEMBER FUNCTION DOCUMENTATION
.SH "QKeySequence::QKeySequence ()"
Constructs an empty key sequence.
.SH "QKeySequence::QKeySequence ( const TQString & key )"
Creates a key sequence from the string \fIkey\fR. 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 "QAccel" context (using TQObject::tr()).
.PP
Multiple key codes (up to four) may be entered by separating them with commas, e.g. "Alt+X,Ctrl+S,Q".
.PP
This contructor is typically used with tr(), so that accelerator keys can be replaced in translations:
.PP
.nf
.br
QPopupMenu *file = new QPopupMenu( this );
.br
file->insertItem( tr("&Open..."), this, TQ_SLOT(open()),
.br
QKeySequence( tr("Ctrl+O", "File|Open") ) );
.br
.fi
.PP
Note the \fC"File|Open"\fR translator comment. It is by no means necessary, but it provides some context for the human translator.
.SH "QKeySequence::QKeySequence ( int key )"
Constructs a key sequence that has a single \fIkey\fR.
.PP
The key codes are listed in ntqnamespace.h and can be combined with modifiers, e.g. with SHIFT, CTRL, ALT, META or UNICODE_ACCEL.
.SH "QKeySequence::QKeySequence ( int k1, int k2, int k3 = 0, int k4 = 0 )"
Constructs a key sequence with up to 4 keys \fIk1\fR, \fIk2\fR, \fIk3\fR and \fIk4\fR.
.PP
The key codes are listed in ntqnamespace.h and can be combined with modifiers, e.g. with SHIFT, CTRL, ALT, META or UNICODE_ACCEL.
.SH "QKeySequence::QKeySequence ( const QKeySequence & keysequence )"
Copy constructor. Makes a copy of \fIkeysequence\fR.
.SH "QKeySequence::~QKeySequence ()"
Destroys the key sequence.
.SH "uint QKeySequence::count () const"
Returns the number of keys in the key sequence. The maximum is 4.
.SH "bool QKeySequence::isEmpty () const"
Returns TRUE if the key sequence is empty; otherwise returns FALSE.
.SH "TQt::SequenceMatch QKeySequence::matches ( const QKeySequence & seq ) const"
Matches the sequence with \fIseq\fR. Returns TQt::Identical if successful, TQt::PartialMatch for matching but incomplete \fIseq\fR, and TQt::NoMatch if the sequences have nothing in common. Returns TQt::NoMatch if \fIseq\fR is shorter.
.SH "QKeySequence::operator TQString () const"
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 TQObject::tr()) in the "QAccel" scope. If the key sequence has no keys, TQString::null is returned.
.PP
On Mac OS X, the string returned resembles the sequence that is shown in the menubar.
.SH "QKeySequence::operator int () const"
\fBThis function is obsolete.\fR It is provided to keep old source working. We strongly advise against using it in new code.
.PP
For backward compatibility: returns the first keycode as integer. If the key sequence is empty, 0 is returned.
.SH "bool QKeySequence::operator!= ( const QKeySequence & keysequence ) const"
Returns TRUE if \fIkeysequence\fR is not equal to this key sequence; otherwise returns FALSE.
.SH "QKeySequence & QKeySequence::operator= ( const QKeySequence & keysequence )"
Assignment operator. Assigns \fIkeysequence\fR to this object.
.SH "bool QKeySequence::operator== ( const QKeySequence & keysequence ) const"
Returns TRUE if \fIkeysequence\fR is equal to this key sequence; otherwise returns FALSE.
.SH "int QKeySequence::operator[] ( uint index ) const"
Returns a reference to the element at position \fIindex\fR in the key sequence. This can only be used to read an element.
.SH RELATED FUNCTION DOCUMENTATION
.SH "QDataStream & operator<< ( QDataStream & s, const QKeySequence & keysequence )"
Writes the key sequence \fIkeysequence\fR to the stream \fIs\fR.
.PP
See also Format of the QDataStream operators.
.SH "QDataStream & operator>> ( QDataStream & s, QKeySequence & keysequence )"
Reads a key sequence from the stream \fIs\fR into the key sequence \fIkeysequence\fR.
.PP
See also Format of the QDataStream operators.
