-sendev msg

Send a message to the Composition Manager. The msg variable must be one of the following:

type=close:[qid|wid]=(int)
type=state:[qid|wid]=(int):index=(int):f=(float)
type=state:[qid|wid]=(int):index=(int):i=(int)
type=state:[qid|wid]=(int):index=(int):l=(long long int)
type=input:[qid|wid]=(int):index=(int):f=(float)
type=input:[qid|wid]=(int):index=(int):i=(int)
type=input:[qid|wid]=(int):index=(int):l=(long long int)
type=jog:[qid|wid]=(int):index=(int):count=(int)
type=pointer:[qid|wid]=(int):index=(int):select=(int):x=(int):y=(int)
type=stick:[qid|wid]=(int):index=(int):x=(int):y=(int):z=(int)
type=keyboard:[qid|wid]=(int):flags=(uint):key_caps=(uint):key_scan=(uint):key_sym=(uint):modifiers=(uint)

-sysres [file]

Dump the current state of the system to a file.

Description:

The io-winmgr utility provides a level of absraction between the HMI player and any application that's running on the system. The io-winmgr manager centralizes all window creation, realization, destruction, and composition activities and allows applications and the HMI to be highly portable.

Examples:

Start io-winmgr:

io-winmgr -start

Dump the current state to a file:

io-winmgr -d ./myoutput/dump
