    It's my first post and want to say Hi to everyone and how much I appreciate this forum :)


    I use B4A for a week now, so I'm a newbie.

    I use GestureDetector to drag views around, but I couldn't find an "onDragUp" event anywhere. I want to fire an event as soon as the dragging ends.

    I tried Activity_Touch, but that doesn't seem to work in combination with the dragging (of course).

    I guess it's really routine but I just don't figure out how to do it. I would be really thankful for any advice how to get this done.

    Best regards

    dim Fx as float
    dim Fy as float

    timer1.interval = 1000
    Timer1.enabled = true

    If View1 Fx AND Fy didn't change for 1000 milliseconds then
    it's dropped and you can do whatever you want.
    End if

    a poorman's solution but will work.. you will lose 1 second though..

    Hi Beja,

    thank you for your quick answer. Yes, I already thought of polling, but actually I wanted to avoid it.
    But maybe there is no other way, at least with this library. :)

    You should look at the log in the Drag example. You would see that a Touch event is raised when you lift the finger.
