Re: [Dynapi-Dev] DynAPI v2 Scroll- Update # 3

[<ni...@pr...>]

just a suggestion 
if I keep the mouse down either in the arrows or the scrollbar itself shouldn't the content keep scrolling instead of having to click every time to move it ?

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

[Doug M. <do...@cr...>]

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

Doug

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.

Doug

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

[Michael P. <mp...@ph...>]

the best method for doing this is using a slide method.  if you start the slide
when the mouse goes down, the slide can be stopped if the mouse comes up before
it has finished sliding.

here's the code I knowckout out of the scrollpane:

    buttonListener.onmousedown=function(e) {
        var scroll=e.getTarget();
        scroll["scroll"+e.getSource().direction]();
        scroll.findDimensions();
    };
    buttonListener.onmouseup=function(e) {
        e.getTarget().cancelScroll();
    };

Here's the viewport code that it extends:
    ViewPort.prototype.scrollUp=function() {this.scrollSlide(null,0);};
    ViewPort.prototype.scrollDown=function()
{this.scrollSlide(null,-this.availableScrollY);};
    ViewPort.prototype.scrollLeft=function() {this.scrollSlide(0,null);};
    ViewPort.prototype.scrollRight=function()
{this.scrollSlide(-this.availableScrollX,null);};
    ViewPort.prototype.scrollSlide=function(x,y) {
        if (x!=null && this.enableHScroll) {
            this.invokeEvent("scrollstart");
            this.content.slideTo(x,this.content.y);
        } else if (y!=null && this.enableVScroll) {
            this.invokeEvent("scrollstart");
            this.content.slideTo(this.content.x,y);
        };
    };
    ViewPort.prototype.cancelScroll=function() {
        this.content.stopSlide();
        this.invokeEvent("scrollend");
    };

Hope this is of some use.
