DESCRIPTION
The QKeySequence class encapsulates a key sequence as used by accelerators. 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, CTRL + Key_P might be a sequence used as a shortcut for printing a document. The key codes are listed in qnamespace.h. As an alternative, use UNICODE_ACCEL with the unicode code point of the character. For example, UNICODE_ACCEL + 'A' gives the same key sequence as Key_A. 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 QString to obtain a human readable translated version of the sequence. Translations are done in the "QAccel" context. See also QAccel and Miscellaneous Classes.
MEMBER FUNCTION DOCUMENTATION

QKEYSEQUENCE::QKEYSEQUENCE ()

Constructs an empty key sequence.

QKEYSEQUENCE::QKEYSEQUENCE ( CONST QSTRING & KEY )

Creates a key sequence from the string key. 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 QObject::tr()). Multiple key codes (up to four) may be entered by separating them with commas, e.g. "Alt+X,Ctrl+S,Q". This contructor is typically used with tr(), so that accelerator keys can be replaced in translations: QPopupMenu *file = new QPopupMenu( this ); file->insertItem( tr("&Open..."), this, SLOT(open()), QKeySequence( tr("Ctrl+O", "File|Open") ) ); Note the "File|Open" translator comment. It is by no means necessary, but it provides some context for the human translator.

QKEYSEQUENCE::QKEYSEQUENCE ( INT KEY )

Constructs a key sequence that has a single key. The key codes are listed in qnamespace.h and can be combined with modifiers, e.g. with SHIFT, CTRL, ALT, META or UNICODE_ACCEL.

QKEYSEQUENCE::QKEYSEQUENCE ( INT K1, INT K2, INT K3 = 0, INT K4 = 0 )

Constructs a key sequence with up to 4 keys k1, k2, k3 and k4. The key codes are listed in qnamespace.h and can be combined with modifiers, e.g. with SHIFT, CTRL, ALT, META or UNICODE_ACCEL.
QKEYSEQUENCE::QKEYSEQUENCE ( CONST QKEYSEQUENCE & KEYSEQUENCE )
Copy constructor. Makes a copy of keysequence.
QKEYSEQUENCE::~QKEYSEQUENCE ()
Destroys the key sequence.

UINT QKEYSEQUENCE::COUNT () CONST

Returns the number of keys in the key sequence. The maximum is 4.

BOOL QKEYSEQUENCE::ISEMPTY () CONST

Returns TRUE if the key sequence is empty; otherwise returns FALSE.

QT::SEQUENCEMATCH QKEYSEQUENCE::MATCHES ( CONST QKEYSEQUENCE & SEQ ) CONST

Matches the sequence with seq. Returns Qt::Identical if successful, Qt::PartialMatch for matching but incomplete seq, and Qt::NoMatch if the sequences have nothing in common. Returns Qt::NoMatch if seq is shorter.

QKEYSEQUENCE::OPERATOR QSTRING () 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 QObject::tr()) in the "QAccel" scope. If the key sequence has no keys, QString::null is returned. On Mac OS X, the string returned resembles the sequence that is shown in the menubar.
QKEYSEQUENCE::OPERATOR INT () CONST
This function is obsolete. It is provided to keep old source working. We strongly advise against using it in new code. For backward compatibility: returns the first keycode as integer. If the key sequence is empty, 0 is returned.
BOOL QKEYSEQUENCE::OPERATOR!= ( CONST QKEYSEQUENCE & KEYSEQUENCE ) CONST
Returns TRUE if keysequence is not equal to this key sequence; otherwise returns FALSE.

QKEYSEQUENCE & QKEYSEQUENCE::OPERATOR= ( CONST QKEYSEQUENCE & KEYSEQUENCE )

Assignment operator. Assigns keysequence to this object.

BOOL QKEYSEQUENCE::OPERATOR== ( CONST QKEYSEQUENCE & KEYSEQUENCE ) CONST

Returns TRUE if keysequence is equal to this key sequence; otherwise returns FALSE.

INT QKEYSEQUENCE::OPERATOR[] ( UINT INDEX ) CONST

Returns a reference to the element at position index in the key sequence. This can only be used to read an element.

RELATED FUNCTION DOCUMENTATION

QDATASTREAM & OPERATOR<< ( QDATASTREAM & S, CONST QKEYSEQUENCE & KEYSEQUENCE )
Writes the key sequence keysequence to the stream s. See also Format of the QDataStream operators.
QDATASTREAM & OPERATOR>> ( QDATASTREAM & S, QKEYSEQUENCE & KEYSEQUENCE )
Reads a key sequence from the stream s into the key sequence keysequence. See also Format of the QDataStream operators.
