Mouse wheel to adjust dial

Hi
I wonder if there is any way to use the mouse wheel to control the value of a knob?
I have tried to right click on the Knob -> Properties -> Key Navigation, but here can I only select items from the keyboard.
Kind regards,
Mattias

I made a modification to the example mentioned below. This does what you want I think (LV 8.6).

Mouse wheel to adjust values of colors/ font size etc

Hello,
Is that possible to make FW CS5 use mouse wheel to adjust values (hue, saturation, font size etc.) similarly to PS?
It's a bit of a drag to have to click the slider and each time I want to fine tune the tone.

You can set the pref mousewheel.withcontrolkey.numlines to -1 on the about:config page.
The pref mousewheel.withcontrolkey.action must be 3 (default)
To open the about:config page, type about:config in the location (address) bar and press the "Enter" key, just like you type the url of a website to open a website. 
If you see a warning then you can confirm that you want to access that page.

Mouse Wheel Scroll - Change Brush Size

Hi
I use the "Liquify" filter a lot, and I've always wanted to be have the mouse wheel adjust brush size.
(I'm not that keen on using the left-right bracket to adjust brush size.)
Thanks.
Q. Barrie

I'm not sure, but with the OpenGL features enabled you can use a couple of combinatorial gestures to change brush size, and it gives you very fine control:
Hold down the Alt key and click the right mouse button down on your image. While holding it down, if you drag the mouse left, your brush will get smaller, and if you drag right it will get larger. Drag it up to make it softer, down to make it harder.

Mouse wheel control isolation in html embed

I've been working on building a flash website, embedding it in html, and have one minor annoying feature that I'm trying to figure out how to get rid of... I've got it so that when the mouse hovers over scrollable content, the mousewheel can be used to scroll the text up and down - if the mouse is over other content in the embedded flash, it doesn't scroll that text section, just the browser window, which is perfect. The problem is that while the mousewheel is scrolling the proper text up and down, the browser is also affected, causing the whole page to bobble up and down as well (the network I'm building it on prevents scaling to fit multiple resolutions, so I'm stuck with fitting it to the resolution that most of our computers use and having other users deal with it being a little small or a little oversized). Is there some way to adjust the code so that when the scrollable text area picks up on the mouseover listen event to allow scrolling via mousewheel, it turns off the browser's scrolling, or am I just stuck with it?

The issue is that once scrolling has reached the bottom of the text area, and there is no more downward scrolling possible, the mouse's scroll wheel starts affecting the browser. The browser is, at this point, now capturing the mosue wheel event, and doing what it "thinks" it should be doing (default behavior). In your case, you want to prevent that...I think what you are looking for is a JavaScript solution (which I don't know of) that prevents the HTML page from receiving the mouse wheel scroll event. It is probably a tag-team effort of Flash getting focus (such as when it's been clicked on), and Flash losing focus, while telling JavaScript that fact so it can prevent handling the wheel event.
Here are some links for more background info:
http://www.nbilyk.com/flash-prevent-browser-scroll
http://fcontheweb.com/articles/scrollwheel/
A seperate suggestion that probably does nothing to help you out is to recommend if there is a Flash application in HTML, that it be the only application, without other HTML content requiring page scrolling. This is more of an overall design issue, as the rules of reality apply, not very practical for every case, either ;-)

Moving sliders in CS6 with the mouse wheel?

In CS3 after clicking onto the slider "triangle" I can then adjust it with the mouse wheel. I don't appear to be able to do this in CS6. Can this be remedied?

LOL!!!
JJ got my points in another thread today, too.

Mouse wheel value update

Hello everyone
I am trying to get the value from "mouse scroll" changed by mouse wheel. The attached code is very simple and seems to be right wired, but it's not working properly. If you run the VI and scroll up and down mouse wheel, you will see that sometimes the value is updated on the indicator, sometimes don't. If you keep using the mouse wheel always on the same direction (i.e. up), the value on the indicator starts to increase but not after every single roll of the mouse wheel. Seems like a lack of sync between the while loop execution and the mouse wheel usage.
Any ideas how to trigger the loop just after mouse wheel usage? I have to sync them.
Thanks

Mouse Wheel Value Update.vi ‏10 KB

Mike
I got your Vis and did some modifications to adjust them to my code and everything is working like a charm. But I would like to understand what's going wrong with my code (the one that I attached on the first message of this thread). I did a very very very simple code that was supposed to do the jog, but it is not working. As I roll the mouse wheel the value on the indicator does not update in sync with the mouse wheel (sometimes it updates, sometimes don't). If I have my code working I can put it inside an event structure on the timeout case and use:
Mouser Enter array - feed timeout with 10ms
Mouse Leave array - feed timeout with -1ms
Anyway, thanks for your code.
Please, help me to understand what's wrong with mine.
Aested, my VI works on my computer too, but the value on the indicator does not update in sync with all movements of mouse wheel.
Thanks

How to fire mouse wheel events to parent container?

Hi,
When I create a JPanel (let's say jParent) inside a JScrollPane and this JPanel is larger than the current viewport I can use my mouse wheel to scroll the JPanel's containt without coding anything about that.
But if I add another JPanel-derived component (let's say jChild) to the first JPanel, mouse wheel events are not received by the first JPanel when the mouse is over the new added child JPanel.
How can I forward child's mouse wheel events to the first JPanel?
If I use:
jChild.addMouseWheelListener(jParent)I must implement a mouseWheelMoved() method in jParent that requires some code to work while it was doing it byitself before...
Thanks in advance for any help :-)
Regards,
Lara.

you have a mouseWheelListener added to jChild?
if so, in the mouseWheelMoved code include this line
jParent.dispatchEvent(mouseWheelEvent);//or to the scrollpane

How to use Mouse Wheel Events

Hello Everyone
I am using Datagrid in my Canvas.
I use mouse wheel to scroll the datagrid. But in one scroll

So Now my requirement is to control the delta value of mouse
wheel event and how to use that with my datagrid so that i will
able to scroll one row through mouse wheel scroller.
Thanks

I want to scroll one row of datagrid with per mousewheel
scroll. I am not getting how to use the scrollMouseWheelMultiplier
property of the IConfiguration class because i am not able to
create the object of this class.
I am using the Flex 3.0 and flash 9 version.

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.

How to remap mouse wheel in single application?

Hello,
I want to achieve simple thing - control audio in Smplayer using mouse wheel. The tricky part is that I need to control the master volume on my AV receiver because the audio in videos is played as bitstream (DTS/AC3 over SPDIF). I'm able to modify the mouse wheel actions in mplayer but unfortunatelly Smplayer doesn't allow such remapping: http://smplayer.sourceforge.net/forum/v … f=2&t=6077
I already use xbindkeys with xvkbd for application specific remapping of both keyboard and mouse. I can remap the wheel for Smplayer window but I'm unable to figure out how to make sure the wheel will work for other applications as well - I'm just unable to simulate mouse wheel action for applications other than Smplayer. (Or is there any other way how to not modify the button for other applications?)
If I try only simulating the wheel, it doesn't work...
# .xbindkeysrc
"xdotool click 4"
m:0x0 + b:4
# or
"xvkbd -text "\m4""
m:0x0 + b:4
However if I add "sleep 0.2" before xvkbd or xdotool, it works (but this is unacceptable delay for me). Also if I try to simulate wheel on keyboard press, it works even without the sleep.
Any help or suggestion?

not really.. sorry

SWF in iFrame - How to get mouse wheel to work

I have been searching for a solution to this for a few days
without any luck. I was hoping someone here may have come across
this problem and know of a solution, or know if it just is not
possible.
I have a static page which consists of an iframe, picture and
a div with some links. The image is an image map and set to load
all links within the iframe. The flash itself is a 360 degree
panoramic view with hotspots (links) within the file that also
point to other pages. My issue is that the mouse wheel scroll is
supposed to be a zoom in/out feature, which work with the flash
file and full screen view. However, when the file is loaded within
the iframe, the scroll wheel on the mouse will only scroll the page
and will not interact with the flash file at all.
The problem seems to be with the following browsers (PC):
Chrome 0.4
Opera 9.5
Firefox 3.0
The zoom works in IE6, although the page does scroll with it.
When I disabled the page from scrolling (see index2.html) the zoom
stops working. This is probably due to the code used to disable the
mouse. I really need to try to get the mouse wheel to zoom in
FireFox 3 though. The large majority of our visitors are PC users
with FireFox 3 or IE 7, so these are the two most important
browsers to have working.
The pages are still currently under development but examples
are online here:
http://www.utoledo.edu/campus/virtualtour/maincampus/index.html
-Normal page
http://www.utoledo.edu/campus/virtualtour/maincampus/index2.html
-Page with scrolling disabled
Does anyone have any ideas for a possible solution? Thanks
for taking the time to help.

As far as I know,there is no facility for detecting mouse scrolling wheel in JDK 1.3.
Check it in the later releases of JDK.

Is there a way to change my mouse wheel's funtion so it will scroll with out

I'm stuck in habit that's hard to get out of. I started editing in Vegas then moved to Premiere CS3.
I never use the mouse wheel to scroll frames. I wish it could just zoom in and out of the timeline like it did in Vegas without me having to push alt-scroll wheel.
I'm might be asking for a lot but is this possible? I just can't break my habit of using just the arrow keys when I want to scroll frame to frame. Even though the alt-scroll has 'clicked' in my brain there's that 10% hesitation. That I know would make me more comfortable.
Call me weird but is there a solution?

Josh
Place the cursor over the Source or the Program Monitor and use the scroll wheel to scroll frames.
(Your post is not that clear whether you want to scroll frames or zoom the timeline as you mention both)

Pressing mouse wheel (or Ctrl + Left Mouse Click) on navigation arrows does not open previous/next page in new tab anymore

I am using the new Firefox Developer Edition as a stand-alone on Ubuntu, so I can still use the "old" version, too.
Everything seems to be working fine, as in I am logged in and setup sync. But a few features I got very much used to are no longer working.
When I click on "About Firefox Developer Edition", it shows these details:
Firefox Developer Edition 36.0a2 (2014-12-09)
Firefox Developer Edition is up to date
You are currently on the aurora update channel.
In my "old" Firefox, I can:
1. Click with the mouse wheel on the navigation arrows to open the previous or next page in a new tab.
2. "right mouse click" on the navigation arrows to see the list of previously visited pages of the current tab, and the ones I visited after the page I am on, if I clicked "back" once or more times. I can then click the mouse wheel or "Ctrl + Left Mouse Button" to open any of the pages in the list in a new tab.
None of this works in the Developer Edition.

To clarify, the list of previously or later visited pages does still show up when I right click on the navigation arrows in the Developer Version, but I cannot open any of the links in the list in a new tab with the mouse wheel or "Ctrl + Left Mouse Click".

All-in-One Qosmio PX30t - Mouse wheel application interruptions

hello there ...
for some reason my mouse wheel has been configured to switch to the start page (tiles).
I find this convenient while operating the desktop activities but during other applications its a bit irritating. Here are examples of what i mean:
1. in google's chrome, i use the wheel extensively to open a new tab. now with 8.1 i cant as the wheel action takes me to start page (tiles)
2. im playing Fable and the block action is set to the mouse wheel (make sense as its the most convenient for such task) but with the defaulted switching behavior .. every time i try to block ..im outta the game to the start page (tiles). I know i could avert this by re-configuring the action to a different button or key, but why not have it as is????
im not sure of these applications to be the only ones as its my first 8.1 use!
thanks.

I'm inclined to agree. At first I thought Toshiba had simply remapped the Middle Mouse Button to bring up the start menu for whatever reason, but from what I can tell the PC actually registers the MMB as the Left Windows Key! Why anyone would think this was a good design idea I have no idea. For me it's just frustrating....
Anyway, I've so far found 2 ways around this:
First; using any other mouse, the MMB functions normally. So you could plug a regular USB or wireless mouse in and presto! Problem solved.
+Of course this is FAR less than ideal. One of the reasons I bought an all in one was for the clean look with matching keyboard and mouse. I don't want to give up a USB port when it already comes with the peripherals built in.+
The second option (The one I'm currently using) is to use key remapping software. I've remapped the Left Window Key to act as the Middle Mouse Button. Now my mouse functions normally.
+The problem with this solution is that the Windows Key on the keyboard now also works like a MMB. I remapped the "drop down menu" key to act as the LWIN key to compensate, but this solution is also far from ideal.+
I think Toshiba should release a firmware (or software??) update that either fixes this issue properly, or at least gives users the option to use the MMB as a MMB.

[SOLVED] Chromium updated to 24.0.1312.52 (175374), no mouse wheel

Just updated Chromium to version 24.0.1312.52 (175374) and the mouse wheel can't scroll anymore, had to install an extension for middle-click to be able to scroll again, anyone else with this problem?

I tried, but this should be labeled as a joke, that gives basically very little difference, they should just look at how Firefox implemented it for a good reference
