[Dynapi-Dev] Re: [Dynapi-Help] Where does this need to be poted?

[Leif W <war...@us...>]

I'm wondering if it'd make sense to have something like a getParent(N) where
N is optional, and if specified, refers to the number of parents above the
current layer.  I'm looking through the code for some way to identify if
it's a dynlayer or just a window object.  I don't know offhand but I have a
hunch.  I just can't seem to find the right bit of code to do it yet.

O.k I just did a little test, and the below code only seems to work if you
put a layer inside a layer, but if your layer is larger than your page (not
in side a layer, but simply on added to the page) it doen't work.. So, how
can you tell if your parent layer is the window or a DynLayer? Or again, i'm
sure its the below code..or, possibly not being able to detect a window size
change??

Dear developer's,

            I wanted to share a code change that I made today with version
3, as it relates to the setDragBoundary function is DragEvents. I noticed
that when you enable boundaries and you have this within a containing object
that was smaller than the one with limits you would get very choppy
behavior. I worked around this by using the eventlistener "ondragmove" and
"ondragstop", by setting my location based on the area of my container..
Then it hit me, while working on the dynapi.function.getimage and some guys
from work whom specialize in oop style programing.. add the code to the core
dragevent.js file (line 113), and not longer worry about it.. So here it is,
and please let me know what  could do better (if any, as math is hard for me
to visualize)..

Origianal Code..
                                                //if (x<l) x = l;
                                                //else if
(x>lyr.parent.w-lyr.w-r) x = lyr.parent.w-lyr.w-r;
                                                //if (y<t) y = t;
                                                //else if
(y>lyr.parent.h-lyr.h-b) y = lyr.parent.h-lyr.h-b;

New Code..
                                                if(lyr.parent.w>lyr.w){ //
We are in a container larger than we are, so use the orignal code..
                                                            if (x<l) x = l;
                                                            else if
(x>lyr.parent.w-lyr.w-r) x = lyr.parent.w-lyr.w-r;
                                                            if (y<t) y = t;
                                                            else if
(y>lyr.parent.h-lyr.h-b) y = lyr.parent.h-lyr.h-b;
                                                } else
if(lyr.parent.w<lyr.w){ //opps we are larger than our container, so make us
smother to our areas..
                                                            if ( (x*-1) < l)
x = l;
                                                            else if (
((x*-1) +lyr.parent.w-r) >= lyr.w) x = lyr.parent.w-lyr.w-r;
                                                            if ( (y*-1) < t)
y = t;
                                                            else if (
((y*-1) +lyr.parent.h-b) >= lyr.h) y = lyr.parent.w-lyr.h-b;
                                                }

The above allows the borders to flow very smooth.. Please let me know what
you think, and if you have a cleaner way of writing the above..

Example:

var container = new DynLayer(null,0,0,200,200,"e0e0e0");
var insideObj = new DynLayer("Inside",0,0,400,400, "blue"); larger than our
container...
container.addChild(insideObj);
dynapi.document.addChild(container);
dynapi.document.insertAllChildren();

Thanks... Brian Hayes.
