Detailed Description

The KGameKeyIO class.

It is used to process keyboard input from a widget and create moves for the player it belongs to.

Constructor & Destructor Documentation

KGameKeyIO()

KGameKeyIO::KGameKeyIO ( QWidget * parent )

explicit

Create a keyboard input devices.

All keyboards inputs of the given widgets are passed through a signal handler signalKeyEvent and can be used to generate a valid move for the player. Note the widget you pass to the constructor must be the main window of your application, e.g. view->parentWidget() as QT does not forward your keyevents otherwise. This means that this might be a different widget compared to the one you use for mouse inputs! Example:

KGameKeyIO *input;
 input=new KGameKeyIO(myWidget);
 connect(input,SIGNAL(signalKeyEvent(KGameIO *,QDataStream &,QKeyEvent *,bool *)),
         this,SLOT(slotKeyInput(KGameIO *,QDataStream &,QKeyEvent *,bool *)));

Parameters

parent

The parents widget whose keyboard events * should be grabbed

Member Function Documentation

eventFilter()

bool KGameKeyIO::eventFilter ( QObject * o, QEvent * e )

overrideprotectedvirtual

Internal method to process the events.

Reimplemented from QObject.

Definition at line 151 of file kgameio.cpp.

rtti()

int KGameKeyIO::rtti ( ) const

overridevirtual

The identification of the IO.

Returns

KeyIO

Implements KGameIO.

Definition at line 146 of file kgameio.cpp.

signalKeyEvent

void KGameKeyIO::signalKeyEvent ( KGameIO * io, QDataStream & stream, QKeyEvent * m, bool * eatevent )

signal

Signal handler for keyboard events.

This function is called on every keyboard event. If appropriate it can generate a move for the player the device belongs to. If this is done and the event is eaten eatevent needs to be set to true. What move you generate (i.e. what you write to the stream) is totally up to you as it will not be evaluated but forwarded to the player's/game's input move function Example:

KPlayer *player=input->player(); // Get the player
qint32 key=e->key();
stream << key;
eatevent=true;

Parameters

io	the IO device we belong to
stream	the stream where we write our move into
m	The QKeyEvent we can evaluate
eatevent	set this to true if we processed the event
