Tool/driver to emulate mouse events?

Hello,
is there a software for my mouse to use an emulated middle mouse button when you click both the left and right button (for example)?

It's called "xdotool" and you find it in the AUR.

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.

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).

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.

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,

Mouse Events on Disabled Buttons

Hi,
In my application I should make a disabled button to show a tool tip when mouse is entered onto it.
I'm using java.awt.container not Jcontainer.
I have searched in SDN forums and after reading some of the comments what I understood is �disabled Swing button can react to Mouse events but a disabled awt button can not react to mouse events�.
Is that true or did I not understand correctly?
And how would I be able to implement the required functionality in my
application?
Thanks.

Allowing Mouse Events to "Fall Through" When Window Activated

I'm implementing a "tool pallette" in my application (much like tools in an application like Photoshop) and I want the user to be able to immediately click on options on this pallete without having to make the window active. Since Swing doesn't have an explicit "Pallete" window that would give this to me for free, I'm assuming I need to subclass JDialog to make this happen.
Even if window activation still must happen, it's crucial that the user only needs to click once to press the button on an inactive window.
I know I can detect WindowEvents like WINDOW_ACTIVATED by simply adding my own window listener, but I don't know how I'd go about having mouse events "fall through" the window listeners and cause the appropriate action on the underlying component. It's almost as if I need to tell the window itself to listen for nothing.
I thought glass planes may be the answer, but that doesn't seem to be what's preventing the intial click in an inactive window from falling through to the underlying component.
Any thoughts, comments, or experiences regarding this are greatly appreciated!

Such a simple solution to such a perplexing problem. You are absolutely right. It turns out I was experience a bug in my particular L&F. Trying this with the Windows L&F proves that simply changing from JWindow to a non-modal JDialog works. Now I'll have to go about getting the bug fixed in the MacOSX (Aqua) L&F so I have equivalent behavior across all our supported platforms.
Thanks for the quick response.

The solution to this problem was posted in the Swing forum. Turns out to be a simple difference of JWindow and JDialog, but a difference I wasn't seeing under all L&Fs (i.e., Windows L&F handles JDialog properly, MacOSX (Aqua) L&F seems to treat it like any other window... I've filed a bug with them).

Iocane: poison the rodent (simulate X11 mouse events from keyboard)

Iocane: the colorless, oderless, tasteless poision that will rid your system of its rodent infestation. Though no promises about its effectiveness against Rodents Of Unusual Size.
Iocane simulates mouse events from the keyboard. Iocane can be passed a few parameters which - ideally - could each have a key binding in your favorite window manager.
If iocane is called with no parameters it starts in interactive mode (which currently lacks documentation ... hey, I just wrote this this morning). In interactive mode the directional arrows or h/j/k/l keys move the mouse cursor. The number keys simulate button presses (1 = left button, 2 = middle, 3 = right). The page up and page down keys simulate mouse wheel activation. "q" quits from interactive mode returning any grabbed keys to their normal behavior. Key bindings are all controlled from a simple rc file.
Iocane can also be passed a series of commands on the command line or the filename for a script file with a list of iocane commands. Iocane can also read command from its standard input.
Iocane is conceptually similar to some functions of xdotool, but iocane should work under any window manager (or no wm at all), is much smaller, and the interactive mode allows for a sequence of many actions without the program having to start up and close down many times in rapid succession.
Please report bugs or feature requests here. Iocane is currently 127 lines of C, and it will remain small; in other words, features will only be added if the can be added without substantially increasing resource use.
EDIT: Version 0.2 is now in the AUR

Any arbitrary number of buttons should be easy enough to simulate - provided the Xserver actually responds to events with that button number. An update I'll push to github tomorrow will include a few changes, including buttons 1-9, but if there is need/desire I could increase that. Sticking to 1-9 allows for the computationally cheaper hack of converting a string to a number by simple substracting 48 from the value of the first character; numbers greater than 9 would require the use of atoi() or some funky conditionals. In the grand scheme of things this is fairly trivial, but unless there is a real reason to use more than 9 mouse buttons I'd prefer to keep the lighter code.
Passing a window name and getting it's coordinates is possible but after considering it I've decided it wouldn't fit well in iocane. The reason being that to do a half-arsed job of it would be pretty easy. To do it properly, however, it would take quite a bit of scanning through recursive calls to XQueryTree, polling atoms/wmhints, matching strings, checking for subwindows in the case of reparenting window managers, and a bunch of other nonsense ... all to get two coordinates.
However iocane will play nicely with any tool that will provide those coordinates from a given window name, so I can imagine and invocation such as the following to move the mouse 10 pixels right and down from the top left of a window - lets call it FlamingSquirrel - and simulate a click there:
iocane $(cool_app FlamingSquirrel) : move 10 10 : button 1
Currently that could only be done from a command line invocation, not from a script or interactive session, as it requires shell processing for the command substitution. I can add support for this type of invocation in scripts and interactive mode as well. Then all you need to do is find (or write) a program that will give coordinates for a window given a title/name. I suspect such a program probably exists out there, or if you are comfortable with C, I could give you the starting framework for it as I made something that would have much code in common for another task on these forums (it's in jumpstart.c in the "misc" repo on my github).
In fact, you could use the following
xdotool mousemove --window FlamingSquirrel 0 0 && iocane offset 10 10 : button 1
Though if you are using xdotool anyways, I'm not sure if iocane would serve much of a purpose, unless you just prefer iocane's syntax.

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.

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

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.

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 ?

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.
