Here is the caller graph for this function:

void Joystick::joystickButtonPressed ( int  axisNumber, bool  buttonState  )

signal

Emits a signal when an joystick button-pressed event occured.

Parameters:

axisNumber	is the number of the joysticks button
buttonState	is the buttons state (true when button is down)

Here is the caller graph for this function:

void Joystick::joystickMoved ( int  axisNumber, int  axisValue  )

signal

Emits a signal when an joystick move event occured.

Parameters:

axisNumber	is the number of the joysticks axis
axisValue	is the axis value

Here is the caller graph for this function:

void Joystick::joystickPOVButtonPressed ( int  buttonsState )

signal

Emits a signal when a POV / hat switch joystick button-pressed event occured.

Parameters:

buttonsState

is the buttons state (normally 0 to 8 on a POV / hat switch) And this is the POV button layout: 1 8 2 7 0 3 6 4 5

Here is the caller graph for this function:

void Joystick::message ( QString  text )

signal

Emits a info or error message to a slot. This slot can be used to display a text on a splash screen, log file, to print it to a console...

Parameters:

text	is the message to be emitted
