start_context

objectobject with parameters of swipe event start current_context

objectobject with parameters of swipe event end

Example

webix.attachEvent("onSwipeX",function(start_context,current_context){
    //your code here
});

Details

Parameters of the start_context and current_context objects are given below:

x - {number} horizontal event position
y - {number} vertical event position
target - {object} the html element where the event started/ended
time - {Date object} the time of event start/end

To check whether the swipe direction is "from bottom to top" or "from top to bottom", you can calculate the difference between currentContext.y and startContext.y. If the difference is positive, swipe movement direction was "from bottom to top". In case of a negative value, the direction was "from top to bottom".

// example of usage
webix.attachEvent("onSwipeY",function(c1,c2){
   if( c2.y - c1.y > 0 ){
        // swipe from bottom to top
    }
   else{
       // swipe from top to bottom
   }
});
