ActionScript 3.0 :: Scrollbar And Loaded Content Of Various Sizes?
Jun 5, 2009
I'm working on a project that uses a loader to load up a swf, then display the loader in an area using a mask and a scrollbar to scroll through the content. The content in this project will change regularly, including the dimensions of the swf file (vertical dimension only, I'm not worried about horizontal scrollbars with this question).The problem I'm running into is I can't figure out a proper formula to get the scrollbar to position the content at it's bottom when the scrollbar is at the bottom What I have now is close, but not exact. If you scoll to the bottom, the bottom of the content would scroll up too high, leaving an empty 'blank' space where the content should be. I have an if statement checking for this currently, but this creates a 'dead zone' at the bottom of the scroll bar where the content is already at the bottom, and the scroll bar can continue to scroll down a bit.oes anyone know what I'm doing wrong here in the math to get a good scrolling going, regardless of the size of the content loaded by the loader?Here is what I have so far:
package { import flash.display.MovieClip; import flash.net.URLRequest; import flash.events.*; import flash.display.Loader; import fl.controls.UIScrollBar; import fl.controls.ScrollBar; import

I have a scrollbar in which a very long list which I can't make any shorter / smaller.roblem is, the script for the scroller demands that I place the text at 0,0 on the Flash axis, and the lenght of the text makes it run way down to the lower edge of the Flash workingfield.Somehow this makes the text run 'beyond reach' of the scrollbar; the scroller only shows about 2/3 of the list, and does not show the text beyond that point.How can I extent the reach of the scrollbar??? Can I shift the 0,0 point of the Flash axis (maybe place it higher, so the text falls into the more 'reasonable' regions of the workingfield of Flash?)

I want to use the built in Scrollbar component to scroll within a movie clip or sprite whose content is generated by a for loop within my code. I can't seem to get it working when I set the scrollbar at authortime to target the movieclip into which i place the for loop at runtime.

I've used Bill T's scrollbar code and loaded text from an XML file. When I drag, the text content is not completely shown.
I'm suspecting it has to do with the value "1.3" in this particular line:
Code:
scrollAmount=(this._height-(mask_mc._height)/1.3)/(mask_mc._height-scrollbar_mc.dragger_mc._height);
how I could use this code, to show up complete text content dynamically?
Here's the complete AS:
Code:
//set a variable
targY=0;
//set the drag action of the dragger

I'm wanting to make a vertical scrollbox (say, 150 px wide by 500 px high with a scrollbar) and where the content is defined by an XML file. The catch... I'd like each name in the list to become a button (or otherwise clickable) that opens a swf (also specified in the XML file). I have succeeded in making a static list where each "name button" was created manually... but I'm realizing my list is going to be hundreds of names and I'm thinking there must be a way to achieve this with XML. Here is the current version:

I have been reading through the Source/Experiments threads and trying to implement suggestions in the Content Scrollbar (Revised) [URL].. thread. I'm using Flash MX 2004, Actionscript 2.0 and throughout the course of this great thread the suggestions seem to shift and become geared for Flash 8. There are a few hints that MichaelxxOA kindly left for MX 2004 people loading content dynamically but I haven't been able to get to work. It's been a long work in progress but I feel like I am getting closer. At the moment I have been able to get the xml content to load into flash but I had to create a kind of dummy cell in the contentMain that is approximately the length of the combined images in the xml document. Is there a way to change the code so that it can read and load the content of the xml document so that when it varies flash loads into contentMain what ever combined height the xml includes? Here is the zip including .xml, .fla, .swf, .as and image with progress so far.

I am new to xml content in flash. I have been through the kirupa tut for loading xml content and have been successful in implementing it, but I now want to implement it into a scrollbar so I can use css and img tags. I can get it to work using the UI scroll component, but I want to use a custom scroll bar. I get the XML to load fine but I have no clue where to stick in the firstChild.childNodes[0] so I can call to certain attributes within the XML document. Below is the AS for the custom scroll bar.
Code:
stop();
holder_mc.setMask(mask_mc);
var LV:LoadVars = new LoadVars();
LV.onData = function(info:String):Void {
holder_mc._txt.text = info;

On my site I want to scroll image boxes vertically. On releasing the scrollbar is there anyway to make the content being scrolled ease into a specified position so that it aligns with other elements on the site instead of stopping at a random coordinate?

I've successfully implemented the scrollbar from this great tutorial for some banners, but when I get to my 300x250 banner, the content gets cut off and disappears at a certain point while scrolling. This is the tutorial: [URL]. I altered the pieces for two different sizes without needing to alter any code, but this size is suddenly giving me problems. My FLA is attached.

I have an application control bar at the bottom of my Flex application (with attributes width="100%", dock="false", left="0", bottom="0", height="50"). It contains a lot of elements (like buttons and labels). The width of the SWF is the width of the browser.When the user makes the width of the browser window smaller, after a certain point, thecomponents on the application control bar gets "squished": they are forced on top of each other. And so, it becomes confusing and ugly. To ensure that that doesn't happen, I've set the minWidth attribute to a value so that it'll always display the components without them overlapping each other.
But then, a horizontal scrollbar appears and hides the bottom half of the application control bar.I've googled and I found this article: flex verticalscrollpolicy bug (referenced by this SO question: Flex: Prevent scrollbar from covering content when automatically displayed).But that seems to apply only to a fixed size component. My component's width is a percentage. how to have the horizontal scrollbar appear and have it not cover up the application control bar?

so i have some scrollbar(track and button) and some content.the formula i am using to calculate to calculate y of content is the following:
//contentStarting.y and scrollbarButtonStarting.y are positions of sprites at the moment they are created
content.y = -((contentStarting.y -scrollbarButtonStarting.y) +scrollbarButton.y) * ((content.height- content.mask.height) / (scrollbarTrack.height - scrollbarButton.height));
the only problem i have is that i need to add extra space after content, so basically i want forumla to act as if content. height = content.height + extraSpace , but unfortunatelly setting the height scalesY, which is what i don't want.

I'm having a bit of trouble with this logic. My setup is typical, with a content MC and a handle MC the runs along a track with specified bounds. All I want to do is have the handle height adjust based on content height but in relation to the track height?

I worked through Kirupa's "Simple Custom Scrollbar" tutorial and successfully adjusted it to fit some of my content. Then I put it in a movieclip. I was hoping I could just go into each new instance of that movie clip, put in new content and be good to go. Unfortunately, when I edit the content inside my movie clip it edits the content of all the scrollbars in my timeline.
I tried renaming the instance "contentMain" to "contentMain2" in a second movie clip, that I also gave a unique instance name to, and adjusting the actions to match, but that still ended up renaming it in the other the scrollbars in my timeline as well as adjusting it in the actions of all the scrollbars.

Mainly been making websites all these years, but in my last year at school i started to get interested in Flash Actionscript. I've been at home for over a year in 2008, unemployed. I got back to school in September 2008 but quit the education as it wasn't for me. Now I'm looking to get a job, but I need a showcase, so I'm building my portfolio at the moment.
I'm currently working on my portfolio which i wanted to make in Flash using XML generated content. I got as far as getting the content generated in my prototype. Now I'm trying to build the real thing. I currently got a scrollbar on the left which contains the thumbnails. I used the custom scrollbar from [URL] ([URL]). The content in it is generated with xml and actionscript though.

I am in the process of building a site for an Architect... Jamie Fobert Architects (projects) I am useing transitions between the projects and am loading details/text and images externally through flashvars, php and a mySQL database. Within my transitions I have a a preloader on the forst 2 frames the code is as follows (taken from a Voetsjoeba tutorial):
[Code]....
This works pretty well if the content is within the .swf, but when it is loaded externally it doesnt preload it at all. Does anyone know how I can adapt/improve this preloader? or somehow ensure that all the content being loaded externally is loaded before the transition plays?

I recently purchased a scrollbar from the exchange marketplace and it works beautifully within it's own swf but as soon as I load it into a second swf (the main "start movie") it doesn't work. When I click on it to scroll, the tracker sticks to my pointer (like a mouse follower) and won't release until I click on a button leading me into another movie. The scrollbar component came with an external caurina file which is where I think the issue is coming from. I think it's having trouble finding the associated code when inside the second movie. I've tried all sorts of parent vs root scripts to try and get it to jump a level to recognize the source of the original code.

I'm having trouble getting my scrollbar to work with dynamically loaded movies inside the movie the scrollbar is attached to. An example of my working scrollbar code with static data and my broken scrollbar with dynamic data can be found on a nice webpage I made, but I cannot post a proper link: www cryhavocguild com/actionscript php. Make sure to include the www as my flash file will only load the data with it (another problem). I have a for loop that pulls data from my database, populates a topMovie(contentMain) with 20 subMovies inside it. My scrollbar is attached to topMovie. Once the data is loaded and the topMovie is populated, the scrollFace(not ScrollTrack) dissapears and the dynamic movie is not scrollable. As a test, I populated the topMovie with graphic boxes and no dynamic movies and it scrolls just fine.
Scrollbar code:
scrolling = function () {
var scrollHeight:Number = scrollTrack._height;
var contentHeight:Number = contentMain._height;
var scrollFaceHeight:Number = scrollFace._height;
var maskHeight:Number = maskedView._height;

To just add the articles will only make the page load slower so I used a scrollbar with a textfield and added text and pics to the article to scroll it. This works fine but I need a way where the scroll can call different textfields or movieclips. For instance, the main scroll opens with a textfield that scrolls articles 15 thru 10. I need on the bottom of the page buttons that link articles 9 thru 5 and so on. So when you click a button the textfield or movieclip changes and displays what is in that textfield or mc. I have looked for a tutorial, a video or anything on this and besides coming up with Flash 5 similar mentions but nothing to this point

i have one simple question. I did simple scrollbar for text which is loaded from external file. But, if the text in textfield is too short ( few words ) I dont want scrollbar to roll.
I would be grateful for any useful advice.

I made a scrollbar class that works pretty well. I'm trying to come up with an idea for how to set to the height of the scrollbar vs the height of the scrolling content. This is a standard thing that happen in the OS. Seems there should be a minimum number and the maximum value should be reached as the size of the content approaches the size of the visible area.
