## Detailed Description

The IMouse interface represents the virtual machine's mouse.

Used in IConsole::mouse.

Through this interface, the virtual machine's virtual mouse can be controlled.

## Member Function Documentation

## ◆ putMouseEvent()

void IMouse::putMouseEvent | ( | in long | dx,
|  | in long | dy,
|  | in long | dz,
|  | in long | dw,
|  | in long | buttonState
| ) |  |

Initiates a mouse event using relative pointer movements along x and y axis.

Parameters

  dx | Amount of pixels the mouse should move to the right. Negative values move the mouse to the left.
  dy | Amount of pixels the mouse should move downwards. Negative values move the mouse upwards.
  dz | Amount of mouse wheel moves. Positive values describe clockwise wheel rotations, negative values describe counterclockwise rotations.
  dw | Amount of horizontal mouse wheel moves. Positive values describe a movement to the left, negative values describe a movement to the right.
  buttonState | The current state of mouse buttons. Every bit represents a mouse button as follows: Bit 0 (`0x01`) left mouse button Bit 1 (`0x02`) right mouse button Bit 2 (`0x04`) middle mouse button A value of `1` means the corresponding button is pressed. otherwise it is released.

Expected result codes:

  E_ACCESSDENIED | Console not powered up.
  VBOX_E_IPRT_ERROR | Could not send mouse event to virtual mouse.

## ◆ putMouseEventAbsolute()

void IMouse::putMouseEventAbsolute | ( | in long | x,
|  | in long | y,
|  | in long | dz,
|  | in long | dw,
|  | in long | buttonState
| ) |  |

Positions the mouse pointer using absolute x and y coordinates.

These coordinates are expressed in pixels and start from `[1,1]` which corresponds to the top left corner of the virtual display. The values `[-1,-1]` and `[0x7fffffff,0x7fffffff]` have special meanings as respectively "no data" (to signal that the host wishes to report absolute pointer data in future) and "out of range" (the host pointer is outside of all guest windows).

Parameters

  x | X coordinate of the pointer in pixels, starting from `1`.
  y | Y coordinate of the pointer in pixels, starting from `1`.
  dz | Amount of mouse wheel moves. Positive values describe clockwise wheel rotations, negative values describe counterclockwise rotations.
  dw | Amount of horizontal mouse wheel moves. Positive values describe a movement to the left, negative values describe a movement to the right.
  buttonState | The current state of mouse buttons. Every bit represents a mouse button as follows: Bit 0 (`0x01`) left mouse button Bit 1 (`0x02`) right mouse button Bit 2 (`0x04`) middle mouse button A value of `1` means the corresponding button is pressed. otherwise it is released.

Expected result codes:

  E_ACCESSDENIED | Console not powered up.
  VBOX_E_IPRT_ERROR | Could not send mouse event to virtual mouse.

Note
  This method will have effect only if absolute mouse positioning is supported by the guest OS.

## ◆ putEventMultiTouch()

void IMouse::putEventMultiTouch | ( | in long | count,
|  | in long long[] | contacts,
|  | in boolean | isTouchScreen,
|  | in unsigned long | scanTime
| ) |  |

Sends a multi-touch pointer event.

For touchscreen events the coordinates are expressed in pixels and start from `[1,1]` which corresponds to the top left corner of the virtual display, for touchpad events the coordinates are normalized to the range 0..0xffff.

Parameters

  count | Number of contacts in the event.
  contacts | Each array element contains packed information about one contact. Bits 0..15: X coordinate in pixels or normalized X position. Bits 16..31: Y coordinate in pixels or normalized Y position. Bits 32..39: contact identifier. Bit 40: "in contact" flag, which indicates that there is a contact with the touch surface. Bit 41: "in range" flag, the contact is close enough to the touch surface. All other bits are reserved for future use and must be set to 0.
  isTouchScreen | Distinguishes between touchscreen and touchpad events.
  scanTime | Timestamp of the event in milliseconds. Only relative time between events is important.

Expected result codes:

  E_ACCESSDENIED | Console not powered up.
  VBOX_E_IPRT_ERROR | Could not send event to virtual device.

Note
  The guest may not understand or may choose to ignore this event.

## ◆ putEventMultiTouchString()

void IMouse::putEventMultiTouchString | ( | in long | count,
|  | in wstring | contacts,
|  | in boolean | isTouchScreen,
|  | in unsigned long | scanTime
| ) |  |

Parameters

  count |
  contacts | Contains information about all contacts: "id1,x1,y1,inContact1,inRange1;...;idN,xN,yN,inContactN,inRangeN". For example for two contacts: "0,10,20,1,1;1,30,40,1,1"
  isTouchScreen | Distinguishes between touchscreen and touchpad events.
  scanTime |
