Non-Modal SUD Dialog Possible?

Is it possible to have a non-modal SUD dialog box? I would like to use a SUD dialog box to show some things going on while a script is running, and would like it to operate much like a non-modal message box.
Thanks! Julia

Thank you for your reply, I was hoping to display a table (with changing values) or some images while scripts were executing, but I will be content with the non-modal MsgBoxDisp dialog boxes

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.

Feature request: make the "transform" dialogs non-modal

Currently, the transformation dialogs accessible at Object>Transform are modal. I'm talking about "Move…", "Rotate…", "Reflect…", and so forth. These dialogs, when open, lock the user out of any interaction with the artboard other than the "preview" button, until the dialog is closed.
Even more problematically, they lock the scroll and zoom factor of the current user view, so that there's no way to inspect how a precise numeric adjustment affects a part of the layout outside the current window (or within the current window but very small inside it) without committing the change, inspecting it, and then later undoing if necessary. This creates cycles of tedious user adjustments (especially on small monitors) that really should be possible in one user step, by toggling the preview button on and off, and zooming/scrolling.
This is contrary to most modern UI design principles, which suggest avoiding modes unless they are truly and meaningfully necessary. I don't think this is one of those cases. Photoshop made dialogs for adjustment layers non-modal with CS4, and while there are issues with the newer interface (see John Nack's Configurator workaround), I think it's a win overall. Illustrator needs to catch up in this regard. I realize there is some pretty serious refactoring involved to do this, but it has to be do-able.
In the words of Larry Tesler's immortal Subaru license plate: "NO MODES"!

...make the "transform" dialogs non-modal...
What, and bring Illustrator out of the 1980s?! Are you mad, man?
Just so you know you're not alone; I've been complaining about AI's archaic dependency upon modal dialogs for many years.
...I'm fully aware of the Transform panel...observing that there's another way to do it...doesn't really address any of my points here...
But it's not "another way to do it," because the functionality is not the same. The modal dialogs include crucial functionality that cannot be done in the Transform palette. For example, moving something in terms of distance and direction (diagonally), instead of merely by lame X and Y factors. Or transforming about an off-object center of transformation, rather than merely by the 9-point proxy.
...the "preview" isn't updated on keyboard entry, and the "preview" checkbox need to be manually toggled on and off...
But the preview does refresh (and does not have to be toggled) in response to keyboard entry if that keyboard entry is by the arrow keys. For example: Select something, doubleClick the Scale tool, click your cursor in the Uniform value field, and tap the up/down arrow keys (or press and hold them). The value will increment and the preview will update with each key tap. (Be sure to teach that to your students.)
That does not, of course, negate the complaint, but it does ameleorate it somewhat. The increments are preset; there are no preference settings for them. (Don't even get me started on preferences that should be doc-specific settings, and vice-versa).
Nor does the valid point that problematic dialogs abound beyond just those associated with the transform tools, but I do agree with it. For just one of many examples, it's nothing short of idiotic that the Scale fields of Transform Each do not have a uniform scaling lock, and that only percentage fields are provided and no explicit dimension fields. Illustrator is quite saturated with such inconsistencies and half-baked implementations.
But...you're often arguing with the emotionally attached Illustrator devoted here. So I wouldn't recommend holding your breath. It would probably be more effective teaching Illustrator's shortcomings to your beginning students. Probably one of the easiest ways to explain the problem of modal dialogs is to point out that you can't change the current selection with the dialog open.

How to display non modal dialog box in a Dll call from TestStand implemented in visual c

Dear Jason F.
Applications Engineer
National Instruments
Hello
I did the same way you told me
the non modal dialog appeared and
system hangs and
giving the error message
""SeqEdit.exe-Application Error
The instruction at �0x047fc5b0� referenced memory at �0x047fc5b0�. The memory could not be �read� ""
please solve my problem
and thanks for yours early response
you can email me at
[email protected]

Hi Mkehret,
Does your dialog have ActiveX controls on it? If your DLL dialog uses ActiveX controls and is not programmed in a certain manner it can hang because of a conflict in the threading model used by the TestStand Engine that is calling into your DLL and the model that is required by the MFC ActiveX Container. If you are using ActiveX controls in your dialog, you need to make special considerations for the threading model MFC dialogs that use ActiveX controls need in order to work properly. The example under \Examples\MFCActiveXContainerDlg illustrates how to appropriately handle this situation as well as explaining why it is necessary.
Note: The above example displays the dialog as modal, but this is irrelevant to the problem I am describing.
Again for information on properly creating a dialog class object and displaying it as non-modal refer to the information on MSDN that I referred you to in this post:
http://exchange.ni.com/servlet/ProcessRequest?RHIVEID=101&RPAGEID=135&HOID=506500000008000000E98A0000&USEARCHCONTEXT_CATEGORY_0=_8_&USEARCHCONTEXT_CATEGORY_S=0&UCATEGORY_0=_8_&UCATEGORY_S=0
If your dialog does not use ActiveX controls or after trying the programming method illustrated in the "MFCActiveXContainerDlg" example TestStand still hangs when calling your DLL, try calling your DLL from another environment just to make sure whether the DLL works at all. If the DLL works properly when called by another environment (e.g. VB, VC++, LabVIEW, or CVI), please submit a MINIMAL and REPRODUCEABLE example source project for your DLL for us to look at (please exclude all unnecessary code not required to reproduce the specific problem of displaying the dialog, and include all files necessary to build your dll with any
specific instructions needed to do so).

Imitate modal dialog by non-modal

Hi
I'm trying to achieve modal dialog functionality by non-modal (i have reasons to do that), but I have encountered a real problem:
calling wait() from EDT is freezing everything. Below is source code, in most cases dialog is created inside action listener (in the EDT), so it is the source of problem:
public class TestMyDialog {
     public TestMyDialog() {
          final JFrame jFrame = new JFrame();
          JPanel panel = new JPanel();
          JButton button1 = new JButton("open dialog");
          JButton button2 = new JButton("close");
          button1.addActionListener(new ActionListener() {
               @Override
               public void actionPerformed(ActionEvent e) {
                    System.out.println(SwingUtilities.isEventDispatchThread());
                    Object syncObject = new Object();
                    new MyDialog(jFrame, "title", syncObject);
                    try {
                         synchronized (syncObject) {
                              syncObject.wait();
                    } catch (InterruptedException ex) {
                         ex.printStackTrace();
                    System.out.println("dialog closed");
          button2.addActionListener(new ActionListener() {
               @Override
               public void actionPerformed(ActionEvent e) {
                    System.exit(0);
          panel.add(button1);
          panel.add(button2);
          jFrame.getContentPane().add(panel);
          jFrame.setUndecorated(true);
          jFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
          jFrame.pack();
          jFrame.setVisible(true);
     public static void main(String[] args) {
          new TestMyDialog();
}And main class:

}Any ideas would be highly appreciated.

Any ideas would be highly appreciated. What about... don't ever block the EDT?Why do you mean by don't block the EDT? I'm using wait() because I need the calling thread to stop for a while (close dialog) but unfortunately this thread is EDT in case of ActionListeners....

Focus Problem -- Two Non Modal Dialogs

Hi ,
In my applet, when user does something which is not allowed, I display an error message box (JOptionPane dialog - modal).
There is another dialog box (non modal) that user
can open to view search results and put it aside the
applet window to do some parallel work.
Now when error message dialog appears, the search
dialog box also pops up even if the user
has put this behind the applet window (by clicking browser window or applet, the search dialog goes behind the window).
Can you please let me know, how can I get rid
of this search dialog (non-modal) popup. I mean
search dialog should remain open but should not
come infront (ie should not get focus) when modal
error message dialog pops up.
NOTE: I don't want to make search dialog
a modal dialog.
Thanx,
[email protected]

Thanks for the reply michael. I forgot to mention particularly during my post that i am facing this problem on Solaris system. Running the same application on windows is working fine. I can't make other non-modal dialogs visibility to false because they should be visible on the screen all the time throught out the application life cycle and making it visible/non-visible doesn't get sense in my application. Does anybody is facing the same problem with Solaris system? Plz help.

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

You too can display non-modal dialog boxes: LrDialogs.presentFloatingDialog

Undocumented function: LrDialogs.presentFloatingDialog
ref: http://feedback.photoshop.com/photoshop_family/topics/sdk_lrdialogs_presentfloatingdialog_ and_showstringsdialog_undocumented
This works for displaying non-modal dialog box:
LrFunctionContext.postAsyncTaskWithContext( "test", function( context )
    local LrPhotoPictureView = import 'LrPhotoPictureView'
    local photo = catalog:getTargetPhoto()
    local pictureView = LrPhotoPictureView.makePhotoPictureView{
          width = 400, height = 400, photo = photo,
    local result = LrDialogs.presentFloatingDialog {
        title = "Thumbnail test",
        background_color = LrColor ("white"), -- required for (uncolored) static_text display, else inside of box is black and so can't see black text.
        contents = vf:column {
            vf:static_text {
                title = photo:getFormattedMetadata ("fileName"),
            pictureView,
            --vf:edit_field { - no sirve, presumably keystrokes are not trapped by box.
            --    bind_to_object = prefs,
            --    value = app:getGlobalPrefBinding( 'tempForTest' ),
            vf:push_button {
                title = "Click me",
                action = function( button )
                    app:show{ info="Pushed" } -- glorified call to LrDialogs.presentModalDialog - works.
                end,
    -- LrDialogs( app:getGlobalPref( 'tempForTest' ), result ) -- no sirve.
end )
Enjoy!

For me, it would be very useful, if it was reliable, but so far, not so good.
UPDATE: Bug I thought was in non-modal dialog is also in modal dialog (scrolled_view must not be followed by another components in tabbed container - see comments in code below):

    props.tv = 0

                -- with this here, Lr crashes after adjusting slider and then switching tabs - comment it out, and all is well:
                --vf:static_text {
                --    title = "this cant be here",

Why is javafx.application.Dialog Non-modal???

Hi all,
Why is javafx.application.Dialog non-modal? How can u implement modal dialog box without using swing classes from javafx.ext.swing. All help will be very much appreciated.
Regards,
Draz.

I would like to know that, too. Older examples are using the property modal: true on Dialog, which doesn't seem to exist anymore.

How to create non-modal dialog box?

I'm trying to create a non-modal dialog box. The purpose is to show an alarm for the user but should leave the calling VI continuing to run. I have created such a thing -- the problem is that I can't figure out how to get the dialog box to go away! It stops running but the window just hangs around. See the attached VIs and image.

Non-modal Popup possible- Factsheet in new window

Hi,
I have the requirement that I need to open the account factsheet in a new window. For that I have created a popup which works fine but I need this popup to be non-modal.
Is there any way to do this? Or is there any other solution to open the factsheet in a separate window?
Thanks for your help and best regards,
Katharina

Hi Katharina,
I have a similar requirement.
If you have solved the issue could you please share the solution?
Thanks,

JDialog Non Modal....Default button remains

I've created a non modal JDialog
By doing the following
1. Creating an object of JOptionPane(message, JOptionPane.ERROR_MESSAGE)
2. Adding the JOptionPane object to the ContentPane
3. Creating a button
4. Adding button("End Application") to ContentPane
5. Adding listeners to window and button
The result is a dialog
Message
ICON "OK" Button...............................NOT REQUIRED
"End Application" Button
I don't require the "OK" Button. Is there a way of removing this button. I need the dialog box to be modal so can't use showMessageDialog, rename "Ok" button to "End Application" etc.
Should I be taking a different approach ie Not adding JOptionPane to JDialog??
If the above isn't possible. Do you know where I can find the default error gif on error dialog boxes?
Kind regards,
Jean

Get the error icon with UIMananger.getIcon("OptionPane.errorIcon"). It might throw exceptions while painting because it's expecting to be painting in a JOptionPane. Just catch and ignore the exceptions and it will paint alright.

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.

Non-modal JDialog hides its JFrame "owner"

I'm writing my first significant swing application. It has a JFrame that launches a JDialog. When constructing the JDialog, I have the JFrame as the owner and set it to be non-modal. The dialog is indeed non-modal, since it allows me to click on the JFrame and run it. However, if the two windows overlap, the JDialog is always on top, covering the JFrame, even if the JFrame has focus. This can make it difficult to effectively work with the JFrame while the JDialog is on the screen.
There must be a simple solution to this, but I haven't discovered it yet. Any ideas?

Thank you so much for your reply. I just confirmed that passing null to the JDialog does indeed allow the JFrame to overlay it. However, now if I minimize the JFrame, the JDialog stays up. I'd prefer that it go disappear with the JFrame. Is there a way to "have it both ways"? That is, Is there a way to make the JDialog go away when the JFrame is minimized, but still make it possible for the JFrame to overlay the JDialog?
Thanks again for the original reply.
TIA on this one, too!

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();
     }

Non-Modal SUD Dialog Possible?
