Flex 4 wheel mouse scrolling speed?

Is there a simple way to define a constant speed or should I say predefined step during which the mousewheel scroll vertical scrolling? For example when I programmed my scrollers in flash I did a formula that worked this way:

(1) I want to move the drop down content area with 40px by scrolling the mouse wheel

2) calculated the height of the visible content area and 40px % which I then use to calculate how much the thumb wheel to pass on the track

(3) also a code to reach the top and the bottom of the track of the total/scroller content area.

Here the scroll has a speed of calulating auto but when I put changers to my main application (you know.. browser like scrolls) they seem to scroll very slow. So now I search a property or something to change it somehow to be faster, but could not find anything. Maybe I need to do scrolling custom, but I thought that it would be stupid to not have the scrolling by default... so I ask here.

Another question everyone knows, Flex 4 brings the wheel of the mouse to the Mac? or scrolling still doesn't work here without a workaround and custom code solution?

Thanks in advance!

public function mouseWHeelAccelerator (): void

{

systemManager.addEventListener ("mouseWheel", bumpDelta, true);

}

public void bumpDelta(event:MouseEvent):void

{

Event.Delta * = somenumber;

}

  • EXTREMELY slow mouse scrolling speed

    Hello, I was faced with a problem with my iMac where the mouse scrolling speed is very slow.  It's so slow that my finger feels bad the amount of scrolling, do I just go to the bottom of an average Web page.  I use a third party mouse, but I think it's a problem with my iMac because when I plug the mouse on my Macbook Air it can scroll to normal speed.  I tried to adjust my speed in system preferences, but it does allow me to increase my speed to scroll beyond the 6th tick and even when he is sure the scrolling speed is still extremely slow.

    It may be worth noting that I've just updated my iMac to El Capitan of Mavericks (so it has not been updated in a while).

    Also, the mouse is a Logitech wireless mouse.

    Please help me find a way to increase my speed.

    I found a solution!  I just installed the latest version of Logitech Control Center and it fixed the problem.

  • How can I change the mouse '-scroll-speed of the wheels in Adobe Reader / Acrobat Pro?

    While I am a student, I read a lot of books to the computer with Adobe Acrobat, and sometimes I just skim the pages to find something. What keeps me boring, that although my speed is set to fast in Windows settings, whenever I open a pdf file and zoom in a bit to adapt to changes in Adobe screen, scrolling speed wheel of my mouse to very slow.
    It seems to me, if I would try to scroll in this situation through a say that only 20 pages ebook it could last for years before reaching the end of the pages...

    Any suggestions why or how to change this behavior?

    Here's what I did:

    1) update your rate of scrolling the mouse.

    (2) in order to actually use my scroll rate, I go to select 'View-> Page Display-> single Page continuous' rather than simply 'single Page '. Œuvres fast scrolling.

  • Loss of function of mouse Scroll Wheel

    I took a leap and a leap of faith, the upgrade to Firefox 3. something to 11.0. I work through awkward differences in the user interface, but I'm having a problem with the scrolling.

    I can't put my finger on any particular website or the size of the page, but I find that sometimes my mouse wheel will stop working with Firefox and I have to use the scroll bar to scroll through a document. Once he goes, he went. I can move to another tab that previously scrolls with the wheel and it is no longer made.

    If I close Firefox and restart, the works of wheel scroll again (even with the page on which he left earlier. If I leave Firefox running, switching to another application, the scroll wheel works out there, so it is unlikely that the driver is corrupted.

    I am running Windows XP SP3 and Firefox 11.0 (downloaded and installed 05/04/2012)

    It is perhaps too early to know for sure, but I think that my problem, loss of the scroll wheel of the mouse in the web pages after visiting one or two particular websites and some time, navigation is not a memory leak problem as some have suggested, nor a funky extension, but rather a problem of mouse driver. I am using an IBM mouse brand with the driver bundled with it rather than the standard driver from Microsoft. removed the IBM mouse driver (and mouse) and installed a mouse of brand store using the standard mouse driver Windows XP. This has not hung up again within a few days of use.

    If I have a memory leak problem, I don't think I've met the result of it still. The program (which currently use 10.0.4 ESR) appears to be stable, no crashes, no crash and, Hooray! no problem scroll wheel mouse.

    I miss the function 'button magnifies' with the IBM mouse driver (it also works with the generic mouse when the IBM driver is loaded), but I would lose this function than to lose the scroll wheel and must exit and restart Firefox to retrieve.

  • My 2000 wireless optical mouse scroll wheel works intermittently-"mouse sigal is low."

    Original title: my 2000 optical wireless mouse scroll wheel works intermittently

    I recently bought a set of wireless with an optical mouse wireless 2000, office 100 wireless keyboard and a wireless desktop kit 3.1 receiver. After you have installed the drivers and the Intellitype/point than roulette software of the mouse does not work all the time, for example after clicking on my way in a 80 page PDF manual and long Web page that the wheel seems to not work in one direction, then the other way won't work. I tried new batteries, latest driver bouquet of microsoft site (intellipoint 8.01) moving to the receiver or away to "signal low mouse." Today, however, the mouse is 2-3 feet away from the receiver and it keeps popping up saying ' the mouse sigal is low you want to start the troubleshooter? Yes, I tried this and tried to move the USB without success. Can someone HELP please... Tired of drag and drop

    Same problem here, but I found a way to make this work (in fact there are two ways LOL)

    -Remove one of the batteries.  Believe it or not, the scroll wheel works perfectly when I remove one of the battery (any).  However, I do not know how long it will last since there isn't that one battery in operation.

    OR

    -Remove the lid of dough and remove the batteries.  Use a screwdriver to loosen the screw about 2 rounds (for some reason, I think that it is screwed in too tight).  Replace the batteries and you are or that you set.

    I can't guarantee that my methods will still work, but the fact is that it works for me since then.

  • mouse scroll wheel not

    Stopped my mouse scroll wheel, and I can't tell if it's a problem of software or hardware (out of stock).  I tried to reset the scroll in the mouse control panel and checked for Intellipoint updates, but does not.

    Try a system restore to a Date before the problem began:

    Restore point:

    Do Safe Mode system restore, if it is impossible to do in Normal Mode.

    Try typing F8 at startup and in the list of Boot selections, select Mode safe using ARROW top to go there > and then press ENTER.

    Try a restore of the system once, to choose a Restore Point prior to your problem...

  • The mouse scroll wheel stopped working after windows updates

    I have a Targus optical mouse with a scroll wheel; and he recently worked like this: when you use the scroll wheel in multiple windows, it would scroll the window (to move the vertical scroll bar) goes up and down.  It was a huge time saver, and I was used to it.

    I installed recently a whole bunch of patches from microsoft, including Windows 7 SP1 and Microsoft Mouse and keyboard Center.  The device is not listed in the center of the keyboard and mouse MS, but there is always a control-> mouse Panel.

    In Control Panel-> mouse, it has still the tab saying "wheel" roll the mouse to a notch wheel to scroll the rows x number of rows (it is selectable, I had 3, but tried to change as well); but it no longer works.  Now, it seems, I have to press the wheel to click, which then shows a circular scroll up/down, icon, and then I physically move the mouse up and down, and if I push down to click again on the wheel, I'm back to a regular movement of the mouse pointer.  It's MUCH more inefficient than the use of the wheel, so I'll try to figure out how I can get the drive working again.

    Should I uninstall MS Mouse and keyboard Center?  I thought about uninstalling and reinstalling the driver; but there is no mouse listed in the Device Manager (only has my touchpad there...)  It's a Targus optical mouse amu10usz; and even once, it was working fine before the installation of upgrades...

    Thanks for any help,
    A.J.

  • Move between photos using the mouse scroll wheel in the library module

    I've recently upgraded to LR6.4, in the library, to the Magnifier module, I can't move between photos using the mouse scroll wheel. When I point the cursor on the picture, I get a "magnifying glass". The only way I can move between photos is to click on the film. I was able to use the mouse scroll wheel to move between pictures before. Help, please.

    It doesn't matter whether or not this option is displayed. Just open the preferences and restart LR should dissipate it.

  • E560 Touchpad - scrolling speed

    Hello

    I have an E560 with Win7Pro, my problem is I want to change the speed of scrolling with two fingers when I am scrolling web sites.

    To do this I have open the touchpad settings and set the speed to a lower 'confirm', the scroll has been slower, but only as long the window with the parameters of the touchpad was not closed. After I closed it, the scrolling speed is back as before (fast), when I open again the settings everythings looks that I've set. All the other options I changed for the touchpad are set and after that I closed the working parameters only the scrolling speed will not change.

    I tried to do it with the old drivers and new drivers and in administrator mode, nothing works.

    Maybe you have an idea?

    Brgds,

    I found the solution, but this isn't the way it should be done.

    In the mouse option (I don't have a mouse) in the section "wheel," I had to change 2 lines of scrolling to scroll 1 line. Now, the speed is reduced but the scrolling is not smoth how it should be.

    Problem has been reported to Lenovo support and I hope they'll release in the future new drivers for the touchpad and solve this problem.

  • mouse scroll broken?

    I must have inadvertently done something change that stopped my mouse to scroll. Even on this site, I can't scroll through this area of the body by scrolling the mouse wheel. For some reason, suddenly I need to drag the scroll bar on the right side of the screen to the bottom to scroll down. The mouse wheel does nothing. What I do and how I do of the Nations United do it? Help! Stupidity...

    Hello

    ·        Who is the manufacturer of the mouse and what is the model?

    I suggest you to check if the scroll function works fine in another computer by plugging in the mouse into another system.

    I suggest you to connect a different mouse to the system and check if the mouse works properly on the system or not.

    I suggest you turn on the mouse scrolling wheel on the system and check if the problem is resolved. See the article mentioned below.

    To activate the mouse wheel

  • Dell XPS 13 (9343) touchpad scrolling speed.

    Hello

    So I just took my brand new Dell laptop XPS 13 (9343) today and everything works perfectly. The only problem I have with it at the moment is the speed of the touchpad, because I believe that it is too slow for my taste. I can't find the touchpad settings in the Control Panel, I can't find any drivers concerned for the model I have.

    Is it possible to increase the scrolling speed?

    Holy *...

    In fact, I have an answer for this question...

    Normally I do not have...

    Just stumbled on this one on another site...

    The setting of the speed of the trackpad is actually used for the speed of the mouse.  For example, to increase the number of lines to scroll to the mouse and it affects the speed of scrolling for the trackpad...

    Voila!

  • Satellite Z30 - update driver touch pad with adjustable scrolling speed?

    Hello

    touchpad Alps for W8.1 that is currently provided by Toshiba driver doesn't have an option to set the vertical scrolling speed of the gesture two fingers. With the speed by default, even supported the fingers down without moving them results in a scroll that is the equivalent of PAGE_DOWN, for example way to fast. The version I'm using is the most recent site (tpdrv - 20140306120847.zip)

    There is a registry entry in HKEY_CURRENT_USER/Software/Alps/Apoint that make the situation a little more bearable (ScrollLines set to 1), but there is no way to adjust if it more in the settings or the registry

    A newer driver from the Alps (8.103.404.104) from another company has this option and scrolling works as it should on the lowest speed, but it does not support the 2 fingers rightclick.

    Why toshiba is using an outdated driver that is missing this feature critical? Is a new driver available? Anyone find a solution for this?

    Hello

    My knowledge of the laptop manufacturers change and adjust own pilots.
    Driver versions are always different and are not always comparable with versions of driver outputs of other manufacutrers for laptop.

    As you said above:
    published by Toshiba Alps driver does not support the speed of scrolling, but conversely, it supports the right click of 2 fingers.
    The other driver supports scrolling speed option but doesn t support made finger right click.

    It would be nice to have a driver that will support all the options listed.
    So I think that we can just wait and hope that future versions will support some features more nice to have
