[Dynapi-Dev] DynAPI v2 Scroll- Update # 4 - AutoSizeKnob (just for you Richard)

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 422-6466

Well, I just hope someone fixes the NS problems then, eh?

:-)

I would really like to avoid putting Browser specific code
into my widget..

hehe

BTW: AutoSizing Now has been implemented.

There are two ways to activate this, but neither will have any effect if you
don't dind any layers to the scrollabr.

One way is via an extra boolean parameter on delcaring the object,
(see the last parameter of the below statatement)

true=auto size the scrollknob IF a layer is bound to the scrollbar
false=DO NOT autosize the knob

HScroll = DynAPI.document.addChild(new myScroll(1,116,84,200,16,true));

the other method is to call .setAutoSizeKnob(boolean);

You can enable or disable AutoSizeKnob as will.

Remember: you need to bind a layer to the scroll bar for autosizeknob to
work.

But there is no order in which to call the functions.

What I mean is you can call autsize first, or bindlayer first.
so:
 VScroll.bindLayer(myPanel);
 VScroll.setAutoSizeKnob(true);

Is the SAME as:

 VScroll.setAutoSizeKnob(true);
 VScroll.bindLayer(myPanel);

Later, and have a nice day (I know I am)

And for my next trick: Continuous scroll on mousedown.
