How do make the mouse wheel scroll in my Flex app/component instead of the browser?

Let's say I have a DataGrid or Tree or List component which
has hundreds of rows. When I place my mouse over the component and
scroll the mouse wheel, I notice that [most of the time] it scrolls
the component a little, then starts scrolling the browser window. I
want it to only scroll the component until it reaches the end of
the rows. Any thoughts?

I have confronted the same issue.
Was anybody able to solve it?
I think mx.contorols.TextArea seems to do well.

I use a two button mouse with my Mac Book Pro. It works fine, but after installing Lion, the mouse wheel goes in reverse of what it did (rolling the wheel towards your palm goes up not down the page). Anyone know how to fix this?

First sentence in OPs question:

I guess the track pad settings would look similar to my screen shot?

Zooming/panning using the mouse wheel scroll

Hey everyone,
Lately I've been frustrated by the functionality of the zoom in Photoshop - and I don't mean the Zoom Tool, but simple zoom in/out operations. I seem to recall that the default behaviour in Photoshop was that you zoomed with Ctrl+mousewheel scrolling, and if you just scrolled, then the picture would pan up/down (vertically). And you could untick the "Zoom with scroll wheel" option if you didn't want Ctrl+scroll to mean "zoom".
However for a while now, having that option ticked seems to mean that scrolling (with no Ctrl) is all it takes to zoom in/out, and if you untick the option then you need to press Alt+scroll to zoom; in either case, there is no shortcut for panningup/down.
Anyway, whether this was really ever the case or not, my question is: is it somehow possible to make it so Ctrl+scroll zooms and (simple) scroll pans vertically? Anticipated thanks for any help.

What PS version are we talking about?
Here is the behavior I see in CS4 when all the Zoom options are unchecked in Edit>Preferences, General tab:
- Scroll wheel alone: Vertical pan
- Scroll wheel & Ctrl: Horizontal pan (a little weird that since the cursor changes to a plus magnifying glass)
- Scroll wheel & Alt: Zoom
It's not exactly what you asked for but it's close (Alt instead of Ctrl for zoom).

Issue with Adobe Muse parallax jitters with mouse wheel scrolling vertically.

Hi all,
I'm learning Adobe Muse for the first time to put together a wedding website (http://mattandsangeeta.businesscatalyst.com/index.html), so bear with me as I'm a novice at the software - though I do have the most up version, Adobe Muse CC 2014.
So far, it's been an excellent platform, and for the most part the site functions incredibly well. However, one key flaw I've noticed in it is the parallax scrolling speed when using a mouse.
The parallax portion of the site jitters badly, and while we've found a few improvements for the issue (the best was making sure there was nothing that had scrolling set to "0"), I'm still at a loss for how to get smooth scrolling transition speeds. Every forum Adobe has seems to be showcasing the features, and not troubleshooting this particular issue. A lot of posts are similar, but none seem to be resolved. I've noticed that other parallax pages are smoother with the mouse wheel scrolling down, so I'm hoping it's just an issue with Muse that has a setting or snippet of code that can remedy the issue.
What makes me realize it's the mouse wheel scrolling, and not the site itself, is because whenever I access the site on my surface pro tablet, the parallax runs buttery smooth with touch control or even trackpad control. Same when you click the middle scroll button and pan down. Without any mouse wheel scrolling, it looks great! But with a mouse wheel, it hiccups constantly and ruins the effect.
So, is there any way to smooth out the steps that the mouse wheel scrolling seems to be causing?
Thanks in advance,
Matt

Thanks for the link, however that specific thread was one of the ones I referenced in my original post.
In the beginning of the thread, it's clear that coding can fix the issue, though it's not recommended. More telling is that the response you referenced indicates that the issue is claimed to have been either fixed or mitigated In updated releases of Muse.
As you pointed out earlier, however, Firefox displays the parallax a little better than Chrome, and much better than Internet Explorer. I'm assuming that Adobe Muse Creative Cloud 2014 release attempted to this issue.
So my question kind of remains: am I missing a setting that would make the scrolling more smooth, or is it simply just a limitation of the browser / software / parallax combination?
Thanks again for the responses.

How to smooth scroll a Spark List using the mouse wheel

I've got my Spark List smooth scrolling nicely if I grab the scrollbar thumb and drag it. But when using the mouse wheel, it's jumping itemrenderer by itemrenderer.
Is there any way to get this to smooth scroll? I'm using a List with variableRowHeight = true.
Thanks.

This thread demonstrates how to customize mouse wheel scrolling:

An enhancement was recently added that will allow for customizing the behavior without needing to subclass. See this bug for the details:

JScrollPane - Set the rate of the mouse wheel for scrolling

Hi,
I'm curious to know a little more about the mouse wheel used for scrolling in a JScrollPane. I'm using it for a JTextComponent at the moment, but the scroll rate is really slow.
Is this because of the way swing deals with the mouse wheel, and therefore can I increase the rate of scroll?
Or is it to do with the native OS and the way it processes mouse wheel events?
Cheers,
David

Hey John,
Scroll rate has nothing to do with the OS you'll be glad to know. As far as Swing goes, it doesn't in this case make any assumptions on how you want you 'views' to scroll.
I think LookAndFeel implementations often decide on default behaviour - I suppose this is in essence the whole point of the pluggable LnF framework.
Anyway, JTextComponent is an abstract class so I would not be surprised if it performs like a lame duck! You will however notice that it implements the Scrollable interface. Take a look at Scrollable.getScrollableBlockIncrement() and Scrollable.getScrollableUnitIncrement().
Overriding these methods will give you the behaviour you desire.
Warm regards,
Darren B

Flash freezes in Firefox when I scroll the mouse wheel over a drop down list or text field (possibly others as well).

Whenever I scroll in a drop down menu in Flash in Firefox (for example, I move the mouse wheel just one detent), it just continues scrolling on its own all the way to the bottom of the list and freezes all interaction for about 10 seconds. It's really bizarre.
If I start click and dragging things, nothing happens, and then all of the sudden everything catches up and moves. As an experienced programmer, I can say that it looks like some kind of queuing of keyboard/mouse events with delayed execution. Has anyone else encountered this issue?
I found something from 2008 that sounds similar, although I am not using the sIFR they mentioned: sIFR mouse wheel scrolling freeze in Firefox - Stack Overflow
Seems to be a Firefox-specific issue, although it also seems to be something that has just recently started occurring since updating Firefox.
UPDATE: I was checking my Firefox version in Help > About Firefox, and it showed version 33, but also had a pending update so I restarted Firefox. The problem was no longer occurring at that point. When I checked the version again, it said 33.0.2, but it also said "applying update", with another pending restart. I restarted Firefox again. It's now stable at version 33.1. So perhaps it was a problem with that particular version, or even a temporary issue with that running browser instance.

Using the mouse wheel to scroll, now jumps a few albums at a time unlike before

help! Using the mouse wheel to scroll, now jumps a few albums at a time unlike before ><
In the past I was just able to go into the mouse control settings in control panel and reduce wheel scrolling to 1 page at a time. Now i'm not able to scroll one album at a time anymore, even though my mouse control panel is still set to scroll at one page at a time. Its skipping two albums ahead now and I can't pin point to the album I want now unless if I click on it. I haven't used ituens in awhile so it must be something new on the last 2 updates, I don't see anything in the perference menu.
thx

I can't use the keyboard to scroll. I need to keep my hand on the mouse, otherwise I'd never get anything done. Since I have no problem getting Firefox to scroll one page at a time, and I'm constantly jumping between 3 browsers, it would be nice to be able to scroll a full page at a time in Safari, just like I can in Firefox. Thanks.

How to enlarge the image, the mouse wheel?

is the picture, and I would like to enlarge it mouse wheel all the time. It's possible?

Yes. By holding down the Alt. key, you should be able to zoom in and out with the mouse wheel.
You can also go to Edit > Preferences > General and checkmark "Zoom with Scroll Wheel".

import mx.controls.TextArea;
public class newTextArea extends TextArea
public function newTextArea()
super();
override protected function createChildren():void
super.createChildren();
textField.mouseWheelEnabled = false;
private var scrollAnterior:Number=-1;
private var direccionScroll:Number=0;
override protected function
mouseWheelHandler(event:MouseEvent):void
var dirScroll:int = event.delta <= 0 ? 1 : -1;
if (verticalScrollPosition==scrollAnterior &&
direccionScroll==dirScroll)
return;
scrollAnterior=verticalScrollPosition;
direccionScroll=dirScroll;
super.mouseWheelHandler(event);
it works fine, but now i want to make the same with the
canvas, but seems is not possible override mouseWheelHandler event
in it. Any help or suggestion ?

Mouse wheel scroll event ON CHANGE?

Colleagues,
Very simple question:
How to get mouse wheel scrolling event on change? Without polling?
Is Acquire Input Data.vi the only way to get it?
Thank you in advance,
Andrey.

Hi Andrey,
i think it's not build in. I wrote some years ago the attched vi's, because i also miss this feature. These vi's use the "acquire input data.vi", but it only polls if a control has registered for it.
Hope it helps.
Mike

CS6 Mouse Wheel Scrolling for Fonts in Character Panel

in Illustrator CS6 I can no longer use my mouse wheel to scroll the list of fonts [which appear when you click the down arrow next to the font family] in the Character control panel. I could do this in CS5.
Anyone know how to fix this? I think it dos not work in Photoshop CS6 either.

Thanks Ivan for the quick response.
Yes, if I simply hover my mouse over the Font drop down it allows me to scroll through fonts [but only shows the single, selected font]. This is quite helpful, if I have text selected, scrolling through fonts quickly changes my selected text to the scrolled to font, allowing me to preview fonts fast.
While I do love and use the feature, I still often like to pull up the "full drop down list" of fonts like I've previously mentioned and use the mouse wheel to scroll through the list quickly. This enables me to see many fonts at once, instead of just a single one at a time. But again, this is where the mouse scroll wheel does not seem to scroll the list. I was able to scroll though the list in older versions of Illustrator CS.
I've attached screenshots to show the specific "list" i'm referring to, just so you fully understand what i'm talking about (which I think you already do).

Using the mouse wheel to zoom in/out

Am I missing some preference setting? I use a mouse with a wheel/roller/scroll thingie in between the right and left buttons.
Why is it that in FCP if you are in the Timeline and you turn the wheel you go up or down the video or audio tracks, but in Soundtrack Pro if you turn the wheel you zoom in (expand the view). I like the zoom thing, but when I go back and forth between FCP and Soundtrack, it is annoying.
Besides the horizontal scroll bar at the bottom of the FCP timeline to zoom in and out and besides APPLE + or APPLE - , how else can one zoom in and out if the mouse wheel is not an option?

i prefer "option =" and "option -" as that always zooms in/out of the timeline regardless of the widow focus

Adobe Reader slow when mouse wheel scrolling in Full Screen mode.

When I scroll a pdf in normal mode, its fine, but when I try to view in Full Screen mode, the scrolling is much more slower and it takes more rolls of the mouse wheel to get to the next page. Does anyone know how to improve the scrolling function of the Adobe Reader when viewing a document in full screen mode?

Good that you solved your problem. There will probably be other users that need to solve the same problem and your solution might help many others. The support here comes from users helping other users.
