@input-send-event

-----------------



Send input event to guest.



Arguments:



- "console": console index.

- "events": list of input events.



The consoles are visible in the qom tree, under

/backend/console[$index]. They have a device link and head property, so

it is possible to map which console belongs to which device and display.



Example (1):



Press left mouse button.



-> { "execute": "input-send-event",

    "arguments": { "console": 0,

                   "events": [ { "type": "btn",

                    "data" : { "down": true, "button": "Left" } } } }

<- { "return": {} }



-> { "execute": "input-send-event",

    "arguments": { "console": 0,

                   "events": [ { "type": "btn",

                    "data" : { "down": false, "button": "Left" } } } }

<- { "return": {} }



Example (2):



Press ctrl-alt-del.



-> { "execute": "input-send-event",

     "arguments": { "console": 0, "events": [

        { "type": "key", "data" : { "down": true,

          "key": {"type": "qcode", "data": "ctrl" } } },

        { "type": "key", "data" : { "down": true,

          "key": {"type": "qcode", "data": "alt" } } },

        { "type": "key", "data" : { "down": true,

          "key": {"type": "qcode", "data": "delete" } } } ] } }

<- { "return": {} }



Example (3):



Move mouse pointer to absolute coordinates (20000, 400).



-> { "execute": "input-send-event" ,

  "arguments": { "console": 0, "events": [

               { "type": "abs", "data" : { "axis": "X", "value" : 20000 } },

               { "type": "abs", "data" : { "axis": "Y", "value" : 400 } } ] } }

<- { "return": {} }
