Register mouse events

Hello,
I just wanted to ask if there is an easy way to obtain mouse events (such as mouse down, scroll wheel etc.) within an event structure (as it is possible with the keyboard). Now I'm using a while loop to continuously acquire the mouse state. It would be much more convenient however if I could use events to detect the mouse state.
Thanks a lot in advance for any help!

Hi Nishant,
unfortunately, there is no option for mouse events under <this vi>, only keyboard. Do I have to install an additional package?
Regarding my application:
With the mouse scroll-wheel I want to interactively scale analog output data, i.e.: when I scroll in one direction data for an analog output task is multiplied by a specific value and given to the AO write vi (upscaled), when I scroll in the other direction the data is divided (downscaled).
When I keep the right mouse button pressed and the mouse is moved, an offset is being added to the data corresponding to the length of the mouse move (with the right button pressed).
When the left button is pressed and the mouse is moved, a rotation operation is being done on the data.
I have this implemented using the initialize mouse vis within a continuously running while loop, now I'm rewriting our application and I just realized that it would be very nice, if I could use mouse events just the same as keaboard events can be monitored within an event structure.
Hope I was clear and thank you very much for any help!
Look for pane (or control events) they have mouse events.
I haven't tested the scroll wheel, looking at your code I would register for the mouse move event as soon as a mouse down event is happening as I have shown in my nugget.

Dynamically register "mouse move" event for a VI

Just as in the example ”Dynamically Register for Events.vi” I want to dynamically register a “Mouse Move” event. I use the “Open VI Reference” to get the reference to the VI and I connect it to the “Register For Events” block just as in the example. When I click the block I get a list of events to choose from, but the “mouse move” event is not one of them. How do I select this event?
I have got the program running by copying the “Register For Events” block from the example and into my program, but I’m interested to know how this should have been done.
I use LabView 8.0

I've had the same problem in LV 8.2.1 and 8.5. I found that NI changed how to access the mouse move... it's now available under "Pane." See my attached example, a modified NI Example.

Disabling mouse events

hi,
I am having objects on a JFrame that respond to mouse events. I would like to know how I can disable these events. I use the addMouseListener to register a mouse event on something. Is there a way to remove or to deregister mouse events.
I basically have a game of tiles on a JFrame and I am going to have the human player play against the computer. I want to be able to have turns; computer and human player turn.

Using activex component in openGL app: mouse event issues.....

i'm trying to get the Flash ActiveX control to work in an
OpenGL app. so far i've managed to get the bitmap data and map it
to a texture succesfully. but i'm having problems getting the mouse
interaction to work.
i get an hWnd from IShockWaveFlash's IOleWindow. when i send
mouse messages to it, the mouse is interpreted correctly by
actionscript (for example, i have a custom mouse cursor tracking
_xmouse, _ymouse which works fine).
however, buttons do not behave correctly. rollover is
erratic, and only in rare circumstances can i get a button's
onPress handler to fire.
am i sending the mouse events in correctly? any ideas of any
other way to send them in?

Thank you for you mail,

Absorbing mouse events

In my application, if someone clicks on a button about 10 times before it visually updates itself, the first click, initializes a change in the GUI, and another button appears in the same place. The second click, is then processed after the first press has completed, and calls the action on the next button, and so on and so on. I want to be able to stop it from doing this. Since it is all on the same thread, I can't say, absorb all button clicks until this event is complete, because they are all still sitting in the event queue. I don't exactly have a whole lot of useful methods to use in the EventQueue class to just say, hey remove all mouse events at this point. Any Ideas?
Maybe this will describe the situation better.
Mouse Click #1 added to queue
Mouse Click #1 removed from queue, processing event.
Mouse Click #2 added to Queue
Mouse Click #3 added to Queue
Mouse Click #4 added to Queue
Mouse Click #5 added to Queue
Mouse Click #1 completed event, new screen is visible.
Mouse Click #2 removed from queue, processing event on button on new screen.
...and so on
I want to be able to ignore all mouse events prior to Mouse Click #1's completion.

Suppose that when you start processing a mouse event
you set a busy flag somewhere, and when you finish
processing it you reset the flag. Your mouse listener
checks the busy flag and drops the click event if it's
set.Problem with this is when I'm at the end of the process, then I enabled the flag, THEN the next event gets processed, and the flag is enabled.
As far as disabling and enabling the buttons, I can try it, but I'm betting it is falling into the same scenario as the flag. My big issue is people double clicking, and the clicks are all registering as 1 click, so 2 seperate events get fired, first one changes the screen, second one clicks on the button on the next screen.
I may have some across a solution that I will test later. It involves storing the completion time of the operation, then when starting the next event, check the event time and see if it is after the completion time, otherwise return.

I would at least expect to see the line 134 printed out. I call this spinner from a simple test application, without any event listeners added there.
Has anyone an idea what might happen here?

Hello, you don't register an event handler, you register a listener on the event handler property. So you don't listen for clicks, you listen for changing the registered click handler. You need to register the handler like this:
imgViewDown.setOnMouseReleased(new EventHandler<MouseEvent>() {
     @Override public void handle(MouseEvent event) {
          // your handler
This way you set the mouse release event handler which will be called on click. This code, by the way, would fire your listeners (the onMouseReleased property has changed).

Register an event for illustrator document.

Hi guys,
Is there an any api to register the mouse click event or something on the illustrator document?
Any help would be appreciated.

I can only help yo uwith Windows; its very different on the Mac.
The first thing to do is to find the document's HWND first. You can do that by keeping track of all the 'OWL.Document' window classes; these are the document windows. The best way is to catch the document opened & closed notifiers and see which OWL.Documents appear & disappear as documents are opened & closed. That will let you associate the correct starting point with the current document. As a side note: when looking, you'll need to look in two different ways in CS6+ becuase of the way they organized the tabbed documents in CS6. So you might think you have it all working and then find that it doesn't seem to work if you undock the current document -- just a head's up!
Once you have the document's HWND, you'll need to figure out which child is the one that's getting all the mouse events. That'll depend on what version of AI you're running -- CS5 & CS6 are different (CS4 might be the same as CS5, can't remember, its been a while). The best way to tell is to fire up Spy++ and once you know the parent document window, just stick the message watch on different children (it'll be near the top of the hierarchy) and watch for mouse events when you move your mouse over the document window. Once you know which one it is, it shoudn't be too hard to install a mouse hook on that window (we use SetWindowLongPtr() to get all messages). Obviously, you'll need uninstall & reinstall the mouse hook every time the document changes and/or closes. Once you have the hook though, you just need to watch for whatever click event you want and grab the mouse location (we track WM_MOUSEMOVE because we just want to know where the mouse is, not where it clicks, naturally you'd want something like WM_MOUSEUP).
The coordinates will be in document coordinates so you'll need to use AIDocumentView::FixedViewPointToArtworkPoint() if you want to know the artboard coordinate, but maybe you're okay with the document pixel coordinate, I don't know
Anyways, hope that helps! Mac is similar, but the window methods & strucutres are different -- same idea though: find the right window and listen to its mouse events!

Intercepting alien mouse events?

Hello,
My problem is the following:
Let's say I have a Frame with two buttons on them, A and B.
Usually events for B are handled with listeners inside B:
A.addKeyListener(new java.awt.event.KeyAdapter() {
public void keyPressed(java.awt.event.KeyEvent evt) {
// do stuff
public void keyReleased(java.awt.event.KeyEvent evt) {
//do stuff
Ok now I would like to be able for A to intercept all key events! (mouse events would follow the same principle).
Any idea? I think A should register its interests in ALL key events somewhere but i don't know where and how.

Mouse events don't work on a button from a panel ran in a DLL

Hi.
I have a DLL that loads a panel.
Since it's a DLL I can't do the RunUserInterface() function, because the DLL would be stuck waiting for the panel events.
I only do the LoadPanel().
When I click with the mouse on one of the buttons, the pushing down event (simulating the button being pressed) doesn't happen and the callback doesn't run.
But if I press the tab button until the focus reaches the button and press Enter, the callback of the button is executed.
An even more interesting aspect is that this happens when I call the DLL on TestStand, but on an application of mine that calls the DLL just for debug everything works fine.
How can I enable the mouse events?
Thanks for your help.

Hello Daniel,
I got surprised when I read your post, because I am experiencing something almost the same as you do.
I have a DLL (generated by an .fp instrument driver I wrote) which performs continious TCP communication with the UUT.
It starts 2 threads, each for reading from one of the 2 different IPs the UUT has.
Another DLL tests this UUT (with the help of the communication DLL above) by exporting functions to be called by TestStand steps.
If the second DLL wants to display a CVI panel in order to wait for the user response or displays a popup (MessagePopup, ConfirmPopup, etc), user cannot press the buttons.
Actually, there is a point your program and mine differ. I call RunUserInterface and the button's callbacks call QuitUserInterface, so the execution continues after a button is pressed. The problem is buttons cannot be pressed. I also tried looping on GetUserEvent but it did not solve the problem.
There are 2 findings:
1. I had a small exe to test my instrument driver DLL and the popups in it worked pretty well (this coincides with Daniel's findings).
2. We workedaround the problem by shutting down the communication threads in the instrument driver DLL before the popup appears and restrating them afterwards. Although they are separate threads in another DLL, they were somehow blocking user events on another DLL running.

Mouse Events are slow

Hello everyone,
I'm currently working on an standard as3 (1024x768) app that
is running inside a chromeless Air window to take advantage of the
transparency.
All my tests where done using windows XP professional and AIR
1.0 (the same problem existed in beta3).
The issue I'm having is related with Mouse Events. Somehow
the events take a lot of time to reach the swf file when the user
clicks inside the transparent window.
It's natural that the app runs slower inside a transparent
window (the framerate drops) but I wasn't expecting the clicks to
suffer from such delay (it takes sometimes 2-5sec).
The app is very CPU intensive and the transparencies make it
worse. Something inside the AIR framework is not dispatching the
events properly.
I say this because I tried using the virtualMouse class from
senocular together with a socket to simulate the mouse clicks and
that did the trick.
In conclusion:
Something in the AIR framework for windows XP is messing up
the dispatch of the Mouse events when the app is under heavy cpu
usage inside a chromeless window. I click on the window and it
takes 1-2sec to receive the click event.
However when I dispatch the MouseEvent.CLICK myself using
the virtual mouse class the application immediately receives the
event.
I know this is a strange bug and not many people will have
this problem, but I would like to know from someone with knowledge
of the runtime why this could be happening.
Thank you

Firefox mouse event not behaving the same on PC and Mac computers

I use the FCKEditor and having a very strange problem. When I click on the FCKEditor's editing area, the keyboard gets disabled untill I click the mouse somewhere outside of the editing window. The problem only happen on Firefox (3.6.10) on Mac computer (Snowleopard 10.6.4). Doing exactly the same steps on PC works without any problem.
What I want to know:
- Is it possible that the Firefox on Mac is different than the PC in handling mouse events? Or some other areas?

Sounds more that Firefox is treating that editor area as read-only.
Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).

Non modal PopUpManager blocking mouse events

In our application we have a header, footer and center area. We have a situation where we want to block the header and center area with a popup, but leave the footer area so it can be clicked on. The code works fine and it all looks good, except the mouse events are blocked to the footer. If we slightly resize the window (either with the mouse or programatically) it all "wakes up" and starts working. I have tried all sorts of invalidateDisplayList, validateDisplayList, validateNow, etc. I am throwing this out there to see if anyone else has had this problem and if there is something I am missing. I can't easily share my code, but if I don't get a reply I'll put together a code example to see if I can recreate it. Any ideas are very welcome. Been scratching my head at this one for 3 days now.

I should point out that we are using "false" for the modal flag, just in case anyone was thinking that. It all works fine once it "wakes up" through resizing, but I need to make that happen without the resizing.
And we have tried all sorts of "callLater" behavior in conjuction with the invalidate/validate calls.

Mouse events during Thread.sleep

hi.
I have an applet .
I have a alghoritm simulator.
Everytime I find a solution I call the method Thread.sleep .
I want to pause the application and I create a JToggleButton Pause .
When I press the Pause during sleep mouse event are managed at the end of alghoritm.
How can I manage mouse events during sleep?

All UI events (such as mouse events) occur on the event dispatch thread (EDT).
That means if you sleep on the EDT, you lock up the UI. For this reason, you shouldn't be sleeping on the EDT.
I'm not sure what your sleep is trying to do but you need to manage your threads a little more carefully. For instance, any time consuming process which is invoked as a result of a UI event needs to be fired on a new thread to prevent the UI freezing. The fun starts when you have to update the UI as a result of that process, because you should then hook back onto the EDT to avoid the risk of deadlock.
Some utility classes are provided, such as SwingUtilities, and other example code is provided on Sun's site, such as SwingWorker - but if you do much UI work you'll probably end up with your own core set of threading tools and so on to make life easier.

HTML/JS: Capturing mouse events while Air is out of focus

Hi,
I've been trying to determine if it is possible to receive mouse events (like MOUSE_WHEEL) if the Air window does not currently have focus. I'd like my application to support the mouse wheel for scrolling while the cursor is over the application, without requiring the user to click the application and gain focus. My application uses JavaScript to scroll an unordered list within a DIV set to overflow:hidden (to prevent the native scrollbar from appearing).
Thanks for your help!
Andrew

I doubt that AIR would pick up events fired while not having focus. Perhaps you could fake it by creating an AIR project that runs "fullscreen", but has a smaller active window. Anywhere your mouse went it would still capture the scrolling event, but you could conditionalize it so that it only worked in certain areas.

Mouse Events at the icon in systray.

My program call library function to add, modify or delete icon into systray.
Additionaly I'd like to get back information when any mouse event had happen under icon in systray like move mouse, right/left button click etc. to display popup menu (as an standart behaviour).
I've tried Windows Message Queue, but it only works inside application window area.
How could I do it ?
Any suggestions, examples or advises ?
