RE: [Dynapi-Dev] events and dragevents debugging

[Cameron H. <ca...@bi...>]

Thanks for the fixes Doug. But I think ideally, if the API is solid, we
shouldn't have to put thse work-arounds in our widgets. That's why I think
these are bugs, everyone could apply little fixes here and there to make
things work, but really the core API should work well enough that you don't
have to. Perhaps it is impossible in some cases (content h/w in NS6/MacIE5
sounds that way) but I think it's a goal to work towards.

  Subject: Re: [Dynapi-Dev] events and dragevents debugging


  I've been looking into events problems (ignoring bubbling) and found the
  following issues. Some of these have been reported before. Oh, I've been
  using a modified version of the mouseevents example html file which I'll
  attach to this mail. It's quite useful for debugging, if people can think
of
  further test cases then they should add them :-)

  Win32 IE is my yard stick. IE behave's mostly like I'd expect, so if other
  browsers don't I reckon it's a bug.

  IE:
  If you enable dragging, then you cannot select form text, instead you drag
  the window.

  Are you using the IE text selection fix? Just wondering...

  NS4:
  If you enable dragevents, click and dblclick events are not fired.
  Events are not picked up on the image (but they are using dynimage, so
  what's the difference).


  I came across that too, here was my problem/fix.
  Problem: In NS, one could not click on the buttons at the far right of my
toolbar..
  (www.creative-workshop.com/demo/cwconcept.htm)
  Solution: in the mousedown event of the buttons I disable dragging of the
toolbar
  and on mouseup I 'click' or perform tho code I would have put in onclick
and re-enabled to drag events.
  i.e.
      db1.onmousedown=function(e){
          e.setBubble(false);
          DragEvent.disableDragEvents(ToolBar);
      }
      db1.onmouseup=function(e){
          e.setBubble(false);
          dockClick(e);
          DragEvent.enableDragEvents(ToolBar);
   }
  Unfortunatly you then have a problem with mousedown happening, but then
the mouse moving off the object before comming up and the the mouseup
doesn't get fired of course..
  My solution for that was simple tho.. :-)
      var d1=new EventListener(DynAPI.document);
      d1.onmousemove=function(e){
          e.setBubble(true);
      .......

          DragEvent.enableDragEvents(ToolBar);
      }
      DynAPI.document.addEventListener(d1);



  NS6(using nicolajazz patch):
  Events are still being fired twice.
  When dragging is enabled you cannot select a form input to type into.

  NS6(using my patch):
  Double click events are not being fired.
  I added something to events.js to allow forms to be selected when dragging
  but the problem is probably with dragevent.js not events.js.

  Some food for thought, better get back to the real work now...
