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 = "ntqstring.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 < a href = "ntqstring.html" > TQString< / a > & 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-> < a href = "ntqmenudata.html#insertItem" > insertItem< / a > ( tr("& 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 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 k1, int k2, int k3 = 0, int 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 < a href = "ntqkeysequence.html" > TQKeySequence< / a > & 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 < a href = "ntqkeysequence.html" > TQKeySequence< / a > & 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 = "ntqstring.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 < a href = "ntqkeysequence.html" > TQKeySequence< / a > & 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 > & < a name = "operator-eq" > < / a > TQKeySequence::operator= ( const < a href = "ntqkeysequence.html" > TQKeySequence< / a > & keysequence )
< / h3 >
Assignment operator. Assigns < em > keysequence< / em > to this
object.
< h3 class = fn > bool < a name = "operator-eq-eq" > < / a > TQKeySequence::operator== ( const < a href = "ntqkeysequence.html" > TQKeySequence< / a > & 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 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.
