Member Function Documentation

◆ mouseAt()

void PS2TouchKit::mouseAt ( uint16_t  x,
uint16_t  y,
uint8_t  buttons 
)
overridevirtual

called whenever the mouse moves or it's button state changes buttons is a simple mask with each button (0-8) corresponding to a bit position in the byte with 1 being down and 0 being up

Parameters
xthe x position of the mouse
ythe y position of the mouse
buttosthe button state as described above

Implements VncMouse.

◆ recv()

bool PS2TouchKit::recv ( const std::vector< uint8_t > &  data)
overrideprotectedvirtual

Data received from host.

Data sent to the device is buffered one byte at a time. Each time a byte is added, this function is called and passed the current buffer. It should return true if it has consumed the data and the buffer can be cleared, or false if more data is needed to process the current command.

Parameters
dataPending input data (at least one byte)
Returns
false if more data is needed to process the current command, true otherwise.

Implements PS2Device.
