A way to change the modality of a dialog box modal false after is displayed?

I have a dialog window for users to connect. The window also has a progress bar that updates while the program is loading. I was wondering if any of you can think of a way for me to keep this modal dialog box so that the user logs on (until they click on the button), but then treated her in a modeless way. The answer obvious is briefly hide it, change mode and show once again, but he produced a spark and in my case the positioning changes sometimes, it is not ideal.

I tried to change just the modality in the executed the button action method, but he don't seem to have any effect.

A NBS illustrating the behavior I want to avoid are:
public class ModalDialogExample
{
    public static void main(String[] args)
    {
        //make a modal dialog
        final JDialog dialog = new JDialog( );
        dialog.setModalityType(Dialog.ModalityType.APPLICATION_MODAL);
        dialog.setSize(400,400);

        //put a button on it
        final JButton button = new JButton("Click here to change modality type!");
        dialog.setLayout(new BorderLayout());
        dialog.add(button, BorderLayout.SOUTH);

        //when the button is clicked, change modality
        button.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(final ActionEvent event) {
                dialog.setModalityType( Dialog.ModalityType.MODELESS );
                System.out.println( "I have set Modality type to MODELESS" );
            }
        });

        dialog.setVisible(true);

        //we never get here because the dialog isn't closed.
        //Is there a way to progress to this point while keeping the dialog visible?
        System.out.println( "No longer modal!" );
    }
}
Basically I want the click on a button function in the same way that a modal dialog box from closing normally would, in fact, that make sense?

If you have any questions or need any clarification, please let me know! Thank you.

Hi Caryy,

According to the document entitled: http://java.sun.com/developer/technicalArticles/J2SE/Desktop/javase6/modality/ I think that you have no other choice than to hide and show it again...

Changing the type of modality during execution. Changing the type of modality for a visible dialog box can have no effect until the dialog box is hidden and then shown again.

But using the distribed mechanism of owner in the document, you can be modal compared to an owner and modeless compared to a new framework...

Hope this can help...

  • How to disable the "Insert smart card" dialog box keeps appearing after the connection?

    Running Windows 7 64 bit on a laptop Dell which includes and integrated smart card reader. My configuration does not require a smart card to log on. I was wondering if the smart card reader has worked, I plugged a card chip used on another system. The driver is installed automatically, so it appears the drive works.

    Now, whenever I log in, the "Insert smart card" dialog box is displayed. If I cancel or close the box, he continues to reappear every few seconds. How to disable this behavior?

    Update: this is somehow connected to Outlook 2003. I have 4 different e-mail accounts. The "Insert smart card" box appears only when checking for my att account (yahoo), which is configured by using POP3.

    Go to the Services.msc and check the settings for the smartcard (manual test) service.

    The position of the OP, have been reported since a lot of this problem on the some notebooks Dell and HP. There are a few reports that a replacement of the motherboard fixed the problem and the other that the relocation of a certain connector (no mention of exaclly one that) solves the problem. Direct contact with the manufacturer of the laptop computer, Dell or HP wether, might be useful. Try a follow-up if you have already made contact.

  • Change the link of Action dialog box

    I'm following this tutorial ( Oracle JDeveloper 11 g Release 2 tutorials - creating a Web Application using EJB, JPA, and JavaServer Faces ) and step 2: create a workflow defined with two Pages JSF, step 21. In the dialog box change the binding Action, in the value field, enter #{pageFlowScope.sal} I'm lost - I do not know how to open the link Action Edit dialog. I looked on the internet and it seems that it should open automatically after the addition of data control, but it did not happen or I missed it somehow... How should I open this dialog box?

    User, please tell us your jdev version!

    If you do not get the dialog box (don't know why you don't get it) you can open it yourself. Switch to the links tab (the tab is below the editing area in jdev). You find the action, you need to edit on the left side in the section "links". Select the link of action that you want to change (getEmployeesFindBySal in your case) and click on the pencil icon on the top right. This opens the dialog box you are looking for.

  • on the different ways to change the color of the skin

    I love this video and ever since I discovered it I used the technique of myself, but how it differs from Select / range of colors and using the pipette and replace the skin darker with lighter skin like that? I've experimented with colors and simple forms and I see no difference.

    https://www.YouTube.com/watch?v=3lL8XUUWg_Q

    There are several ways to do the same thing in Color PS. range just selects an area of the same color. Once you get this selection is to you what method you want to use to edit the selected pixels. The curves were a way to change the tone of a color box. This video is just brushes in this correction, where as selective color selects these areas for you and may or may not give you a more accurate choice - could be too specific and show the transition.

    Is there a way to change the font size in the comments to a readable/superior police box? I went to Keynote > Preferences > General and tried making it bigger, and it does not work. Keynote 6.6.1 thanks.

    The fonts themselves, or one of the font attributes cannot be changed; (size, color, tabs or alignment)

    Although it would be very helpful to change the font size, in normal circumstances, this should not be a problem; comments are designed as a personal note by the designer and should only ever be seen by them.

  • Is there really no way to change the spacing of grid icon?

    My new iPad Pro is pretty well what I was hoping, with the exception of the 4 x 5 grid incredibly Needless to the app icons. On all other devices I use, this big screen would be comfortably and readable display four times more items, or more, avoiding to go back between home pages. I already spent a lot of time wandering through my pages trying to find applications of interest, and I just started to charge this device with the stuff I use. I understand the desire for consistency on all platforms, but this seems extreme. In this logic, all iOS devices should all have the same resolution too. As far as I can see, the only way to change the icon spacing is to jailbreak the device. Is this true?

    There is no way to change the spacing of app icon. Have you tried to use folders on your home screen?

  • HP OFFICEJET PRO 6230: Best way to change the settings WIFI on HP OFFICEJET PRO 6230

    Hi all

    Just after some advice about this printer. It's the printer be mobile , so it can be taken with the Member of staff, connected to wifi where they are and then the group they present to can do impressions of him through their ipads (via AirPrint).

    This all works well 'in House' connected to our wireless network. Have set up the printer wireless via the software installed on their laptop computer (with a USB cable to transfer the settings of the printer), but y at - it an EASY way to change the SSID and password wifi when they are there in the area? I know you can hold down the button "wifi" on the printer for three seconds (until the wireless flashes) then hold down the button "WPS" about to access/reuter and they have a link but it's only if WPS is available and that the staff member can access the reuter/access point.

    They will have their laptops with them and USB cable in order to re - set the SSID and password, but seems a bit lengthy to go by "connect a new printer" for each site they visit. Is the right way to do it or there at - it another way 'over easy' I forgot. I guess also here the printer remembers SSID/passwords so that there be set up a time for a given location and then will be "auto-connect" if they come back? Is this correct?

    Any help on this is much appreciated.

    See you soon,.

    Andy

    Not the printer that you want to do.  Here is the Guide of the user for you to read on your wireless options.

    http://support.HP.com/us-en/product/HP-OfficeJet-Pro-6230-ePrinter-series/5390318/model/5390319/manuals/

    You will need to run the configuration each time to connect software.  You could try Direct another wireless to connect to the printer.  You need a printer with a Panel for configuration complete front so you can easily change the SSID.

    Whatever it is, everyone will have to load the software in order to use the printer.  It can automatically connect, but do not count on it.
