Sliders, click events?

I'm using a slider which gets updated using a setInterval. But i also want the slider to detect when a user clicks it & drags it to a certain point so i can get that value.. (Like a timeline in a audio player).

But how is that done? Since the api tells me:
fired when the device detects a click (longer than touch) against the view.

It says VIEW, but it's written at the UI.Slider desc.. does this mean it just can't handle clicks? Or detect any other events, except for the change event?

    You said you have a setInterval that update the slider.
    So you could do something like this:

    var slider_changed_by_me = false; // this is global -  this is the flag
    function_in_setInterval() {
    slider_changed_by_me = true;
    ... your stuff ( slider.value=.... )
    the_slider.addEventListener('change', function() {
    if ( slider_changed_by_me ) {
    slider_changed_by_me = false; // we reset this once the event was triggered
    //don't do nothing
    else {
    // user triggered the change because slider_changed_by_me is false
    ... your stuff

  • You should be able to detect a click by handling the click event.

    UI controls inherit most events from Views - that's why it says View in the event's description.

    • Thanks, but that does not work..

      If i created lets say my slider like this:

      var sl = Ti.UI.createSlider({
      touchEnabled: true
      sl.addEventListener('click', function() {
      alert('Clicked the slider');

      The click event simply does not get fired.. :(

  • Slider seems to be a little buggy right now. So you will have to use the change event.

    If "change" event triggers when you do it by code too, you can set a flag to detect if the change was done by your code or by user.
