    Description

    Controls if COM events generated by CEF3 Client Processes are fired in their own stack or in the IPC stack. Default is true.

    Property type
    Read-write property
    Syntax
    Visual Basic
    Public Property asynchronous_com_events As Boolean
    Remarks

    When CEF3 sub processes generate events they use SendMessage to post the event to the ActiveX process.

    However, SendMessage is blocking and the event fired must return before any other WebKitX API can be called.

    This setting enables a mechanism where event data are copied to a queue and a timer fires the events by reading the queue.

    In essence this makes the event fire in its own stack instead of the SendMessage IPC stack.

    You should use this for Single Threaded clients as it improves performance and compatibility.
