How to block signal in QML

PawlosCK

Hi. How can I block/unblock specific signal in QML? For example "onContentYChanged".

It's a bit unclear to me what you want to do. If you are programatically changing contentY and you don't want a "feedback"-like reaction of your code you could define a

property bool busy: false

which you set to true while doing your thing. The method "onContentYChanged" can then be made conditional:

onContentYChanged: {
    if (!busy) {
    }
}

Hi. I did it and it didn't work. I mean, slot should not be executed, but I saw logs from this slot.
I wanted to block signal at startup (and later in some cases), because function setValues adds new items at startup and this signal was invoked.
I tried to disconnect signal from object using something like this (it's not from my code), but it didn't work too.

 mouse.clicked.disconnect(say);
 mouse.clicked.connect( function(){ console.log("22222")  });

Next, I tried to use "Connections"

        Connections
        {
            id: connection_signal_move_items
            target: listviewID
            function onCurrentItemChanged() { listviewID.moveItemsTouchAndMouse() }
            enabled: false
        }
		
		connection_signal_move_items.enabled = false
		connection_signal_move_items.enabled = true

and it didn't work too, so I didn't know where is problem. I thought, that I did something wrong and I started this thread.

Currently, I started use other signal and currently looks well. I have to test it more.
