    @:event(ItemEvent.COMPONENT_EVENT)                          public var onComponentEvent:ItemEvent->Void;
  • b
    the reason you dont find it anywhere is because nothing calls that... it will simply use "dispatchEvent(ItemEvent.COMPONENT_EVENT)"
  • b
    that event, in case there is a misunderstanding, is when you have a custom listview renderer that has sub components in it... so you can get events from them
  • b
    onXYZ are just sugar generally
  • b
    its a shortcut for 
    registerEvent(...)
    , keep in mind though, you can only have one, so:
  • b
    Copy code
    myButton.onClick = ...
myButton.onClick = ...
  • b
    this will result in a single event listener, ie, the last one you assigned
  • b
    Copy code
    myButton.registerEvent(...)
myButton.registerEvent(...)
  • b
    will result in two event listeners

    Thanks, Ian! That makes sense, and yeah I was looking for it because I was thinking I wanted to do some custom events of my own for my components :)
  • b
    that live inside a listview?
  • h
    No... I was going to try to copy the pattern eventually if it was simple enough. What I was doing is making my own "sortable" list view
  • b
    right... gotcha
  • b
    sortable list sounds interesting... i wonder if the data source should have a "sort" function
  • h
    It is working with a rudimentary drag and drop atm, I plan on it being able to drag and drop into multiple sections eventually
  • h
    Sorry, it's DND sortable*
  • b
    gotcha
  • h
    but also that sounds like a good feature too
  • b
    sort still sounds useful on data source
  • b
    yeah
  • h
    should min-height style work for vbox?
  • h
    It doesn't seem to do anything while height does . . .
  • b
    can you open a ticket maybe with a test app - in meetings at the moment
  • h
    Will do asap! I have work in about 30ish minutes ... I didn't sleep today :D
  • b
    @User - you said textfield doest dispatch UIEvent.CHANGE, correct? It does for me
  • b

  • b
