postMessage

The postMessage() function is used to send a message to a thread.

postMessage(msg)

The parameter msg is the message to be sent.

msg true Any type supported by the system, such as string, number, bool, object, array, function, null value, etc.

function main() {
    var t1 = threading.Thread(function() {
        for (var i = 0; i < 10; i++) {
            Log("thread1 postMessage():", i)
            threading.mainThread().postMessage(i)
            Sleep(500)
        }        
    })
    for (var i = 0; i < 10; i++) {
        var event = threading.mainThread().eventLoop()
        Log("main event:", event)
        Sleep(500)
    }
    t1.join()
}

Send messages in concurrent threads and use eventLoop() to receive message notifications.

function main() {
    threading.mainThread().postMessage(function(msg) {
        Log("func from mainThread, msg:", msg)
    })
    
    threading.Thread(function() {
        var func = threading.mainThread().peekMessage()
        func("in " + threading.currentThread().name())
    }).join()
}

It supports sending a function.

When a thread’s execution function calls the postMessage() function to send a signal or data, a message event is also generated. We can use the eventLoop() function to receive message notifications.
