InDesign panel: Mouse events dispatched twice on some computers
We've got a InDesign panel built with the Flex-based SDK and it's running in CS 5.0, 5.5 and 6.0 with no problems in a fair amout of installations (100+ different machines in all parts of the world). However, recently two customers reported a very strange issue that left us scratching our heads and I'd welcome any troubleshooting help since we are in the dark here.
The problem in these two particular instances is that all mouse clicks in our panel are dispatched twice meaning that fold-out tree views are immediately folded back again, drop-down menus are closed right away etc. We have not been able to find any common factors and not reproduced it ourselves. For the drop-down menus in particular we have no custom event handling at all so it's all internal to the Flash runtime as far as I can tell.
Obviously both problematic computers are out of reach for us (remote parts of the world) and the people who use them are busy in daily production work and can't pause for extended periods of time to allow for in-depth debugging.
Some observations that may help isolating the bug:
- On one Mac a newly created user account runs the same version of the ZXP perfectly with the same installation of InDesign CS 5.5.
- The second problematic Mac runs CS 5.0 and it is said to have been working about two weeks ago with no Adobe updates since then.
- Both machines have standard Apple mouse.
- The computers have been rebooted, the ZXP has reportedly been reinstalled, and on the second one I personally ran a Webex session where I witnessed that Kuler (also Flash-based, right?) didn't exhibit the same behavior.
- During the Webex session I could successfully use keyboard navigation to operate the same widgets (e.g. fold/unfold tree nodes).
I'm not that familiar with the runtime architecture of these Flash-based extensions to really know if the system-wide Flash Player is involved or if the runtime is entirely bundled with InDesign and not user-upgradeable. One customer tried upgrading to 11.5 just in case but nothing improved.
The customer with one machine where two user accounts had different behaviors has unfortunately (but understandably) reinstalled the user account since they cannot wait for this to be solved. This leaves me with a single instance (the CS 5, v7.0.4) where this bug is repeatable. Any idea on what I should try next while at the same time not interrupt the person's workflow too much?
Hello Walter,
thanks a lot for your help - it does work perfectly, I just added a line like this:
myPanel.addMouseListener( new MouseAdapter() { } );But may you please say some words about the solution, I did not quite understand what you said about the propagation of the events. I must admit, I'm not very familiar with the event system and how these are propagated (from parent to child or vice versa?), so I can fully understand it and avoid those mistakes in the future.
Thanks a lot!

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.

Solved!
Go to Solution.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 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 JOptionPane in a non-event dispatching thread
I am currently working on a screen that will need to called and displayed from a non-event dispatching thread. This dialog will also capture a user's selection and then use that information for later processing. Therefore, the dialog will need to halt the current thread until the user responds.
To start, I tried using the JOptionPane.showInputDialog() method and set the options to a couple of objects. JOptionPane worked as advertised. It placed the objects into a combobox and allowed the user to select one of them. However, it also gave me something unexpected. It actually paused the non-event handling thread until the user had made a selection. This was done without the JOptionPane code being wrapped in a SwingUtilities.invokeLater() or some other device that would force it to be launched from an Event Handling Thread.
Encouraged, I proceeded to use JOptionPane.showInputDialog() substituting the "message" Object with a fairly complex panel (JRadioButtons, JLists, JTextFields, etc.) that would display all of the variety of choices for the user. Now, when the screen pops up, it doesn't paint correctly (like what commonly occurs when try to perform a GUI update from a non-event dispatching thread) and the original thread continues without waiting for a user selection (which could be made if the screen painted correctly).
So, here come the questions:
1) Is what I am trying to do possible? Is it possible to create a fairly complex GUI panel and use it in one of the static JOptionPane.showXXXDialog() methods?
2) If I can't use JOptionPane for this, should I be able to use JDialog to perform the same type function?
3) If I can use JDialog or JFrame and get the threading done properly, how do I get the original thread to wait for the user to make a selection before proceeding?
I have been working with Java and Swing for about 7-8 years and have done some fairly complex GUIs, but for some reason, I am stumped here. Any help would be appreciated.
Thanks.This seems wierd that it is functioning this way. Generally, this is what is supposed to happen. If you call a JOptionPane.show... from the Event Dispatch Thread, the JOptionPane will actually begin processing events that normally the Event Dispatch Thread would handle. It does this until the user selects on options.
If you call it from another thread, it uses the standard wait and notify.
It could be that you are using showInputDialog for this, try showMessageDialog and see if that works. I believe showInputDialog is generally used for a single JTextField and JLabel. -
[svn:fx-trunk] 9328: Fixing SDK-22462: Event dispatched is not as expected in Tree

Fixing SDK-22462: Event dispatched is not as expected in Tree
For this, the issue is really that TreeItemRenderers assume that no click event can occur on the disclosureIcon. This is because the discolsureIcon is added and removed each time it goes through invalidation in commitProperties(), so a new discolsureIcon gets created and replaces the old one after they mouseDown (meaning no click event actually occurs). Automation replays some mouse events on one disclosureIcon only (which is an automation bug because that?\226?\128?\153s not how it actually works in the real world) and when a ?\226?\128?\156click?\226?\128?\157 occurs, that causes an itemClick on the Tree, when it shouldn?\226?\128?\153t. For Flex 3, this wasn?\226?\128?\153t a problem because the IR was getting invalidated through a different codepath because openDuration did not default to 0. If you set it to 0, you?\226?\128?\153d see the same problem in Flex 3. Anyways, the fix is just to block all click events that occur on the disclosureIcon.

Hello,
I'm developing my first Swing application.
One of the components is a thumbnail image panel (ext. JPanel) containing several other components (mostly ext. JLabel). I have the image panel receiving mouse events so as to allow the user to see when the image panel is 'in focus' (rollover effect basically) and to allow the image panel to be selected by clicking.
I added a tooltip to one of the contained labels, and it now 'consumes' my mouse enter/exit event so that now it is as if the label is not part of it's container. This is not what I want.
Is there not some simple way to allow mouse events to be listened for by a child component but yet to 'fall through' to a listener in the parent component?
Any insight into this little problem would be most appreciated.
Thanks.You can listen to all MouseEvents generated:
Toolkit.getDefaultToolkit().addAWTEventListener( new AWTEventListener()
public void eventDispatched(AWTEvent e)
System.out.println(e);
}, AWTEvent.MOUSE_MOTION_EVENT_MASK + AWTEvent.MOUSE_EVENT_MASK);You would then need to determine if the source component is a descendent of your main panel. -
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?

I noticed a confusing behavior
regarding event dispatching when a control holds a
mouse event.
Usually, in a standard GUI framework, when you resize a
spliter, the event is not dispatched to other control.
it's not the case with a flex spliter. The event is thrown to
all controls the mouse moves over during the drag of the spliter.
how can we stop that?
thanksAfter some internal discussion, I hear that this is not a bug
after all. Here is the recommendation (from our dev team) for you
to get all of your mouse events to one target -
1- add a mousedown handler to their component.
2. in the mousedown handler, add a mousemove and mouseup
handler to the systemManager. These handlers should be registered
for capture.
3. in those handlers, do what you need to do, then stop
propogation of the event (see the methods on the event class).
4. in the mouseup handler, remove the mousemove and mouseup
handlers. make sure you remove them from the system manager, and
also set the capture flag in the remove.
HTH,

Trying to create a surface with multiple images with mouse events
novice programmer (for a applet program)
hi trying to create a surface i.e jpanel, canvas, that allows multiple images to be created.
Each object is to contain a image(icon) and a name associated with that particular image. Then each image+label has a mouse event that allows the item to be dragged around the screen.
I have tried creating own class that contains a image and string but I having problems.
I know i can create a labels with icons but having major problems adding mouse events to allow each newly created label object to moved by the users mouse?
if any one has any tips of how to acheive this it would be much appreciated. Thanks in advance.

Not Running on the Event Dispatch thread, but UI still freezes
The environment: I am currently working on an application that requires some heavy lifting in response to user input on a UI. To do this I am using a version of SwingWorker that was backported from java 1.6 to java 1.5 in conjunction with a slew of custom threads.
The problem: I am currently running into an issue where I am not operating on the Event Dispatch thread (checked by doing a javax.swing.SwingUtilities.isEventDispatchThread()) but the UI is still freezing during this section. The operation involves a loop with about 2000 iterations and contains several file accesses. I have thought about how to make a new thread to perform the same operation, but I do not see how it would be any different since as it is I am not on the EDT. The call is being made from doInBackground and specifically the piece that is slowing things down is the File Accesses (2 for every iteration of the loop). At this point I am not sure how to go about resolving the issue. Any one have any suggestions?I am not operating on the Event Dispatch threadThat is the problem. Use multiple threads for GUI, which should delegates to the EDT, and your app logic.

Event Dispatch Thread Hangs, what is wrong?
The Event Dispatch Thread Hangs when showing a modal dialog while running a
SwingWorker Thread.
I have included my code at the bottom of the page. There are three classes. I have posted a bug report to red hat. But I want to make sure my code is correct.
My test case just puts the SwingWorker to sleep
but the problem occurs if I do something real, like connect to a database, etc.
Also I have tried little different variations of the logic calling
setVisible(true)/(false) in different places and the same problem occurs.
It seems to work with Sun JDK, note I am using IcedTea with Fedora Core 8.
Version-Release number of selected component (if applicable):
[szakrews@tuxtel ~]$ java -version
java version "1.7.0"
IcedTea Runtime Environment (build 1.7.0-b21)
IcedTea Client VM (build 1.7.0-b21, mixed mode)How reproducible:
Every couple times.
javac TestClass2
java TestClass2eventually it will hang. If it doesn't try again.
You don't have to wait for the program to finish either.
The program runs the Dialog 10 times but it never works or fails in the middle, it will either work or fail from the first dialog displayed.
I have included a thread dump. That is about the most informative information I can get. Neither tracing nor writing a custom ThreadQueue or Drawing Manager to trace events produces any helpful information.
Actual results:
The JProccessBar won't move, and the SwingWorker finishes but the done() method is never run. The PROGRAM is not hung however because if I close the dialog then it will continue.
Expected results:
The JProccessBar should always move and the SwingWorker should always run the done() method.

}There's nothing directly wrong with it, but it will
prevent other threads acquiring the class lock - but
that may be what you want.True. Although the typical case for code that looks like this would be to use wait--usually the various threads in question require the same lock, so you have to use wait in order for the waiting thread to give it up and allow the other thread to do its work. Hard to say for sure though what he's doing.
Also, if loading is all that the other thread does, and you're waiting for that thread to die, use join. But then, if that's the case, and you're only waiting for a single other thread, then you might as well just put it all in one thread, as already indicated. -
I need to make a task with less as3 code and more timeline structure and event dispatcher !
I went to an interview in a big company. I had to make a task in which there is a wall with 3 lines and 5 columns filled with bombs.When you click on a bomb the bomb changes its scale, a robot enters, goes under the bomb and takes it, then goes to a smaller wall, makes the bomb smaller and place it at the same place it had been in the previous wall.I made the task with tween througout as3 code.The interviewer told me it was good but i need to make it with the less code possible and with more complex timeline structure and to use event dispatcher.What is the best way to do this ?
The immediate thing that comes to mind is they might want to see that you can balance work between design teams and development teams.
To do that, the robots movements (pick up bomb, bomb grows/shrinks, arms/treads/legs moving, sequences of 'doing things') can be timeline based so animators can work on those separate from code.
Developers would be working on the logic of keeping score, moving the robot around to the correct spot with path detection, collision detection, etc.
It's very similar to thinking in simple factories (which Flash is good at being automatically with timelines), and a bit of MVC (or just VC in some cases).
Big companies have lots of different types of employees so you'll probably be very specific in your role so you're efficient. -
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

Which event dispatched after text selection done on spark text area in Apple iPad using Adobe Flex 4
I need to know which event triggered after text selection done in Apple iPad. This way i have done in desktop air app code (mouse events)
protected function txtEditor_mouseUpHandler(event:MouseEvent):void
if(txtEditor.selectionAnchorPosition != txtEditor.selectionActivePosition){
showNoteToolBar(event);
txtEditor.focusEnabled = true;
txtEditor.setFocus();
But in Apple iPad how to achieve through "Touch Event" ? And also i need how to hide all context menu on Spaek TextArea?. Why Touch.End event is not fired after place cursor on text area ?
Please help me !Ok, so I finally got it working but this is not ideal at all. Adobe really needs to give us some direction on how to properly deal with font embedding and TLF now that the release build breaks all functionality with loading runtime fonts and TLF.
Problem:
I am embedding collections of fonts (faces) into single family classes. Each individual face is registered with Font.registerFont(). I need to do this because I have to have mixed fonts within text flows - at least according to Alex H's recent blog post.
Fonts do not display in TLF without doing the following:
1. GlobalSettings.resolveFontLookupFunction = null;
2. editor.textFlow.flowComposer.swfContext = ISWFContext(this.getFontContext("AnyFamilyNameFromAnyFontEmbedded", false, false, FontLookup.EMBEDDED_CFF));
3. Instead of #2, use editor.textFlow.invalidateAllFormats();
Either #2 or #3 need to be performed. If I have a spark richEditableText control in MXML with defined familes from the loaded fonts. I even tried placing the control into a separate state so it wasn't created until after the fonts were loaded... I still needed to invalidate the formats or set the context.
The "AnyFamilyNameFromAnyFontEmbedded" does not need to be all of the embedded family names. It only needs to be one of them. Once one is used, all embedded fonts work. Also, I have to use the internal namespace to even get access to getFontContext, another oddity that, in my humble opinion, should never be necessary to create mixed style TLF content.
My questions are then:
1. Why am I required to use ISWFContext if I am using Font.registerFont()?
2. Why is GlobalSettings.resolveFontLookupFunction = null; also required for this to work?
3. What is the recommended workflow to embed fonts from multiple SWF files into the release build and have it work without having to jump through all these hoops? -
Information Regarding :Exception occurred during event dispatching
Hi,
I frequently get this exception when I click a button in a dialog and it opens up another frame of window. The exception trace includes java internal classes and my program classes line numbers. I have searched the net but could not get any concrete answer.
Is this problem in java packages or should we take care of something in our code to avoid such exceptions.
Below is the exception trace..........................

Thanks in advance.Hi All,
Thanks for the replies and information posted by you.
Below is some code snippet: ( complete code posting is difficult) ;-)
Dialog1 is open, clicking on button say start it hides the current Dialog1 and opens the status dialog for Dialog1.
Also, we are making the current Thread to sleep to avoid flickering.
dialog1.hideWindow(); // Hide current window...
Thread.currentThread().sleep(5); // sleep to avoid flickering..
statusDialog.showWindow(); // to display status window..
I will check and try to do modifications as per your suggestions.
Thanks.
