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.

Capturing Blocked Mouse Events

Does anyone know of a way for a displayObject to receive
mouse events, as the target of that event (MOUSE_OVER, MOUSE_DOWN,
etc) if it happens to be overlapped by another display object. I've
tried setting the .mouseEnabled of the obscuring displayObject to
false, as well as setting its .mouseChildren to false, but no joy
there. Is there a way for the obscuring displayObject to pass the
event along to display objects that happen to be beneath it?
Is there a trick that I don't know of, or is this simply not
possible?

Non-modal JDialog is not painted and blocks the GUI

I have developed a GUI that's basically a JFrame with a JDesktopPane.
The user can, via a menu item, pop up a JDialog that contains some JLists and then select some value from it. Once he/she has done the selection and clicks on OK, the dialog disappears (data processing is then done in the main GUI) and comes back once a specific event has happened. The user then selects other data and so on, until he/she clicks on Cancel, which definitely disposes of the JDialog.
The graphics of the JDialog are build in the class constructor, which does a pack() but does not make the dialog visible yet. The dialog appears only when doSelection() is called.
     /** Called the first time when user selects the menu item, and then
     when a specific event has happened. */
     public Data[] doSelection() {
          dialog.setVisible(true);
          // ... Code that reacts to user's input. Basically, the ActionListener
          // added to the buttons retrieves the user's selection and calls
          // dialog.setVisible(false) if OK is clicked, or calls dialog.dispose()
          // if Cancel is clicked.
     }Now, everything works fine if the JDialog is modal, but if I make it non-modal only the window decorations of the JDialog are painted, and the control doesn't return to the main GUI. Calling doLayout() or repaint() on the doSelection() has no effect. How can this be fixed?
I hope I have been able to explain the problem satisfactorily, I could not create a suitable SSCCEE to show you. Thanks in advance for any hint.

Ok, I've taken some time to think about this problem and I've modified the code a bit.
Now the dialog shows itself and is responsive (i.e. its JLists can be operated), but the Ok button does not close the dialog as I'd want. I believe that I'm messing up things about threading, and the operations in actionPerformed() should be carried out in another thread, if possible.
Thanks in advance for any hint / suggestion / comment / insult.
     private Data[] selection;
     /** Constructor */
     public MyDialog() {
          // ... Here is the code that builds the dialog...
          dialog.setModal(false);
          dialog.pack();
          // Note that the dialog is not visible yet
     public Data[] doSelection() {
          operatorAnswer = NONE_YET;
          dialog.setVisible(true);
          while (operatorAnswer == NONE_YET) {
               try {
                    wait();
               } catch (InterruptedException e) { }
          return (operatorAnswer == OK ? selection : null);
     public void actionPerformed(ActionEvent evt) {
          if (okButton.equals(evt.getSource())) {
               operatorAnswer = OK;
               retrieveSelection();
               dialog.setVisible(false);
          else if (cancelButton.equals(evt.getSource())) {
               operatorAnswer = CANCEL;
               dialog.dispose();
     private void retrieveSelection() {
          // ... Here is the code that retrieves selected data from the dialog's JLists
          // and stores it in the "selection" private array...
          notifyAll();

JWindow blocking mouse wheel event?

I have created a custom JPanel that acts as a container for another custom component that needs to receive mouse wheel events. When I place the custom JPanel in a JWindow the mouse wheel events do not get invoked, all though other mouse events work just fine. If I place the JPanel in a JFrame the mouse wheel events are invoked just fine (along with other mouse events).
To keep things simple the JPanel handles the mouse listeners. Any idea why it would work when in a JFrame but not a JWindow?

The below sample code exhibits the behavior I am talking about on my system (1.6.0_16 on XP). Does it work for you? Is there something I am missing?

Problem with non modal ADM dialog

I have problem with focus and mouse and keyboard event passing to non modal dialog if some modal window was opened and closed on Windows platform.
I have this problem in my plugin, but also I did some tests with SDK WordFinder Plugin.There are 2 dialogs open there : CountDialog-non modal dialog and PromtDialog-modal one. I commented all lines in function DeleteCountDialog to leave this dialog on the screen. So, first, when "create page map" menu is selected, CountDialog is appearing and stays on the screen. At this stage, it can be moved and get focus when is clicked.After that, I click on "find word by word offset" and then PromtDialog is appearing. when I close Promtdialog by clicking on OK or Cancel, CountDialog is "freezing" - means, it can not be moved and does not get focus when I click on it.
Is it known problem ? Is there is some workaround there ?
thanks in advance,
Lidia.

Thanks a lot for your response.
I did changes as you recommended, but still have the same result.
So I have WordFinder from Acrobat SDK 8 with only one file changed:WordFinderDlg.cpp - see below.The result is the same:
1. I open Acrobat->Open some file
2. Click on "Advanced->Acrobat SDK->Word Finder->create Page Map" menu
3. "count" non Modal Dialog is opened and working and then stays on the screen and can be moved without problem.
4. Now I click on "Advanced->Acrobat SDK->Word Finder->find Word By Offset" - Modal Promt Dialog is opened. click some number and then click ok - choosen word is selected in Acrobat. From this moment, first "Count" dialog is frosen - can be selected, can not be moved.
The only workaround I see here is to create non Modal dialog every time I close Modal one.
Could you please advice ? May I please send to you project in zip ?
I really need it ASAP ?
thanks in advance,
Lidia.

JButton on XP non-modal Jdialog doen't work.

I recently upgraded from 1.3 to 1.4 while upgrading my OS from NT 4.0 to XP.
In a stand-alone application I have non-modal JDialog's that are launched as threads so that I can have multiple instances of them running simultaneously. There are JButton's on the JDialog's which no longer respond to any mouse events even though I can execute them via the keyboard using the tab and enter keys. They work just fine under 1.3 or if I make them modal.
Any thoughts?

Hello,
Issue is-
There are JButton's on the JDialog's which no longer respond to any mouse events even though I can execute them via the keyboard using the tab and enter keys. They work just fine if I make them modal.

Howto create non-modal dialogs using ADF Faces

I would like to use Dialogs in a non-modal manner.
Trying to use
<af:commandLink useWindow="true" action="dialog:infoPopup" blocking="false">
<af:setActionListener from="#{row.xyId}" to="#{infoPopup.currentId}" />
</af:commandLink>
doesn't work as expected. I'll get the dialog, but I can't use the page behind it.
Alternatively I tried to show the page using Javascript opening the pageInfo.faces, but here I have an order problem. The onClick event is processed first and the #{infoPopup.currentId} will be populated after rendering the JSF page. But I want to show infos depending on the xyId.
Is there any other way to open windows/dialogs?
Thanks in advance
Stephan

The "blocking" attribute basically just blocks you from clicking the commandLink or commandButton twice (or more) before the first click has been processed by the server and a response has been received.
It is a very good util for avoiding those unwanted IndexOutOfBoundsExcepions when a user hits many buttons thus sending multiple requests to the server.
By the way, I'd like to see the answer to the non-modal dialog window, because we have a need for them, too.
Kind regards,
dj

Showing non-modal popup in overlay of browser.xul - on Windows

Hi. I've got a custom Firefox add-on in plain Javascript. It to overlays Firefox's browser.xul (via chrome.manifest) by an XUL file, where I would like to show a non-modal popup (or some kind of non-intrusive notification).
I've tried following three options from https://developer.mozilla.org/en-US/Add-ons/Code_snippets/Alerts_and_Notifications:
1.
Components.classes['@mozilla.org/alerts-service;1'].
getService(Components.interfaces.nsIAlertsService).
showAlertNotification(null, 'Some title', 'Some message', false, '', null);
2.
var win = Components.classes['@mozilla.org/embedcomp/window-watcher;1'].
getService(Components.interfaces.nsIWindowWatcher).
openWindow(null, 'chrome://global/content/alerts/alert.xul',
'_blank', 'chrome,titlebar=no,popup=yes', null);
win.arguments = [null, 'Some title', 'Some message', false, ''];
3.
var message = 'Another pop-up blocked';
var nb = gBrowser.getNotificationBox();
var n = nb.getNotificationWithValue('popup-blocked');
if(n) {
n.label = message;
} else {
var buttons = [{
label: 'Button',
accessKey: 'B',
popup: 'blockedPopupOptions',
callback: null
Neither of them works on Windows. The first two work on Linux (Fedora 20 x64). Neither of them generates any error either.
Please, suggest how/where to do that, or how to 'schedule it' (as an even handler to a system event, I suppose) from my overlay of browser.xul.

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.

LoadMovie - How to block background events

Hello,
I use loadMovie to load a movie into a current movie clip,
the movie is
currently on the top, but how to block other objects/events
so that only
if this movie is closed, other can interact?
I mean the loaded movie should be `modal`
Thanks.

Not sure if this is what you mean but basically you have a
movie clip on top of other objects that can have mouse interaction
in them. You want to prevent those objects from having mouse events
happening when this current movie clip is on top of them.
In as2 unless you can turn the visibility of everything in
the back to 'false' you need to create a movieclip/button that
act's like a click blocker. It will lie between the current
movieclip and everything behind it.
create movielclip called clickblocker and give it this code:
clickBlocker.onRelease = function () : Void {};
clickBlocker.useHandCursor = false;
so basically it acts like a button that does nothing and
prevents the mouse cursor from turning into a hand.

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.

Non Modal Window Popup BSP View

Hi,
I have a requirement to launch a pop up window which will allow the user to access the original screen from which the pop up was launched (i.e. a non modal window). The pop up window contains a calculator with the intention being that the user would be able to view and copy data displayed on the original screen into the fields of the calculator.
I have created the calculator as a form view within a BSP component. All of the fields on the form view have been configured using the configuration tab. I have successfully created a modal pop up using the following on the buttons click event:
comp_controller->window_manager->create_popup( ).
However, this does not meet my requirement because the form view is displayed in a modal window. I have also attempted to load the pop up using javascript however the view does not initialise correctly when it is loaded which causes a null reference error.
Can anyone please provide any advice or assistance related to creating a non-modal window for a configured form view within a BSP component? Many of the examples I have found online are related to WebDynPro applications and html pages with flow logic rather than configured views with a controller class.
Thank you.

A non-modal, but "always on top" JDialog

Hi everyone,
In an applet I am creating, I need to create a non-modal JDialog which stays on top whenever its open. The reason this JDialog is required to be non-modal is that I need the main applet window to be able to react to events and reflect changes in the non-modal JDialog.
I was wondering how this can be achieved.
To summarize the problem:
How can you have a JDialog whose modal property is "false", but stays on top of the applet window.
This problem has been bugging me for quite a while now, so any pointers will be appreciated.
Thanks,
Alan

Here is how you do it in an applet (as opposed to JApplet):
* Browser sniffer *
      boolean isNN4=false,isNN6=false,isIE=false;
      Frame F;
      JSObject window=JSObject.getWindow(this);
      JSObject document=(JSObject)window.getMember("document");
      String tmp=document.getMember("all").toString();
      if (tmp.equals("undefined")) {
         tmp=document.getMember("getElementById").toString();
         if (tmp.equals("undefined")) isNN4=true;       // Netscape Navigator 4
         else isNN6=true;                               // Netscape Navigator 6
      } else isIE=true;                                 // MS Internet Explorer
      if (isIE) {
         F=new Frame();
      } else F=(Frame)getParent();
now you have a frame for use with the Dialog (not JDialog) method
...Just add the code shown above in the init method of your applet.
Good Luck!

Change a modal JDialog to non-modal JDialog

I created a modal JDialog initially, for some result i need change it to a non-modal JDialog, is there any set modal command can do it??

Nope.
The reason is because of program flow:
System.out.println("first line");
JDialog dialog = new JDialog(modal);
dialog.setVisible(true); // blocks this flow if and only if modal is true
System.out.println("second line");
Try putting a button in the dialog which prints out "button pressed".
If you press the button each time before closing the dialog you will get:
when modal is true:
first line
button presed
second line
when modal is false:
first line
second line
button prese

1. Non-modal popup or 2.minimize button on titlebar of popup

Hi All,
Firstly, is it now possible to open non-modal pop-ups ( as many pop-ups after executing an action method :( ) , or has anyone come across this found a work-around for this ?
currently, I am opening a modal dialog itself. But when I click the minimize ( since minimize, maximize and close buttons are activated in the title bar ), the popup minimizes and maximises immediately. This is now raised as a bug and I need to find a solution for this.
Would much appreciate help,comments or views on this ?

In your case, you can set it to live.
