Ultimate AS 3 OOP ScrollBar

Very classy. I like that you have the arrow key listeners hooked up also.

Wow! Neat scroller! Smooth and quick! I like it!

but the only thing I noticed:
the scrollbar’s height sometimes does not auto-resize..

@diddlejuice, what do you mean? because it has arrow keys listeners…

@RJFlash i got that also, i think it’s an issue on the preview swf, i’m checking that now.

nice

Great one ^^

hey this works great & is easily customizable. Thanks!

I’ve bought this scrollbar, it’s ok so far but it has a nasty bug. While having a fixed drag icon height, when you stop the drag midway of the scrollbar and then an event comes and changes the target, the drag icon resizes to the full height of the scrollbar and sticks that way, making it unusable before you change the target again.

PLZ FIX THE BUGGGGGG !!!!

PS. (“playing” with the reset() and init() positions in the code doesn’t change a thing)

Hi there,

Excellent scrollbar class! Very well done, highly recommend it for people who are using it for intric scenarios where there’s a lot of masking.

VERY QUICK QUESTION : I need to be able to tell the scroll textarea to move to the TOP of the textfield. I can’t seem to find a function in the library to do this automatically and I’m rather tied up to dig through the code logic.

What’s the easiest way to get this done?

Thanks,

Dave

yeah looks great, cant understand the bug clumpster talks about.

I’ll buy this if you add mouse wheel scrolling support which is what I see as a standard method for people ‘scrolling around’ these days

it does too although I dont see the immediate need for the hittest thats pretty cool thanks for this, code looks pretty clean!

I am trying to get the horizontal scrolling iworking. Like it says I change the Boolean value before the init, after this the height of the Drag sprite is stretched and the content disappears. Are you able to provide a working example for the horizontal scrolling you mention in the description and readme.

Hi Guinetik,

Is there any way to instantiate the scroller in pure AS3 ? I don’t mind having the associated assets for the arrows etc in the library, but I would like to create the scroller without the need to drop the components directly on the stage?

Cheers

Hi Guinetik,

Just a confirmation from yourside. As it stands now your “scrollTarget” does not support the ability to grow at runtime. i.e. add more children to the target container.

I am about to modify the code to support this.

Cheers

Hey Guinetik,

I’m also guess this control does not support “upward” scrolling. i.e Like say for example creating an IM Chat client, where the messages must scroll upwards. This would require the “drag” clip to start in the bottom position as opposed to it’s default top position as it is now.

PS: I still love this control for it’s simplicity. Two .as files is perfect for my needs and the fact that it only takes up 2k is SUPER AWESOME .

Cheers Bruce

Hi Guinetik,

With regards to dynamically adding content to the scroll container at runtime, this should help you out.

As you know, setting a scrollRect on a displayObject makes it pretty difficulty to calculate the displayObjects overflow height. (unless it’s text). Doing a check on the _targets actual height, the “overflow” height, can be achieved like this. _target.transform.pixelBounds.height

Adding that line as check to your _target will give you the ability to dynamically have content added to the scroll container at run time.

Cheers Bruce

Hi Bruce,

In case you are still visitng the page!

I am trying to add content in the target dynamicaly too. I just want to add a dynamic number of MCs vertically.

Would you please share some code regarding your solution? Unfortunately my Actionscript skills are not good enough to implement this without your help. So i would definitely appreciate some lines of your code!

Hey guinetik,

Nice work here and good functionality.

Just a question,

I have made a small scroll area, but the masked movieclip I have passed in has a very large height. The mouse wheel is now very twitchy.

In contrast when the scrollarea is very tall and the content is slightly taller, the scroll speed is very slow.

Any way of making the scroll speed consistant? I can kinda see the logic of this, but wouldnt be able to execute this change in my time frame.

Got any ideas?

Cheers,

Sam
