Detailed Description

Handles mouse movements and clicks.

This class ensures correct initialization of the mouse and, above all, its interrupt handling.

Constructor & Destructor Documentation

Mouse::Mouse ( unsigned  max_x,
unsigned  max_y 
)
inlineexplicit

Constructor.

Defines a virtual window for the mouse.

Parameters
max_xMaximum X position (excluding) for the mouse
max_yMaximum Y position (excluding) for the mouse

Member Function Documentation

void Mouse::getPos ( unsigned &  x,
unsigned &  y 
) const
inline

Retrieve the current mouse position.

Parameters
xReference to variable for the X position (0 ≤ x < MAX_X) of the mouse
yReference to variable for the Y position (0 ≤ y < MAX_Y) of the mouse
Optional:
Implement method
bool Mouse::isPressed ( MouseButton  btn) const
inline

Check if a given mouse button is pressed.

Parameters
btnButton to check for press
Returns
true if button is currently pressed
Optional:
Implement method
void Mouse::plugin ( )

Initialization of the mouse.

Initialization of the mouse and activation of the specific interrupt handling: The object will register itself at the Plugbox and configure the IOAPIC to receive the corresponding interrupts.

Note
The mouse interrupts should be configured as level triggered.
Optional:
Implement method
void Mouse::trigger ( )
virtual

Handling of mouse interrupts.

Processes interrupts triggered by the mouse.

Optional:
Implement Method
