    Answered: Issue: Parameters in Event function


    Hello,

    I am new to Sencha Touch, I can't figure out which params and in which order should be used in Event function: e.g.

    Code:
    onDoubleTap: function(event, html, obj)
    Code:
    onDragend: function(draggable, event)
    It seems param event is not always the first param.
    where can I check params for each event or where defines how to add params

    Thanks a lot !
    best regards !

    If you are listening to an event on an Ext.Element instance, the params are always:

    Code:
    tap: function(e, node, options) {

}
    If you are listening to an event on a component, we try to keep a consistent signature. In most cases, the component is the first argument, then any related arguments after that:

    Code:
    hiddenchange: function(component, floating) {

}
    Unfortunately in some cases, this does not happen. We are improving the event signatures drastically in ST2 before GA.
