JDialog close button event.

Hi ..
I wanna know how to handle the close button at the
right top of the JDialog window. Im referring to the
cross button. We can do it throught windoClosing event
in Frames, but how can we do it for JDialog!
any sort of help would be appreciated.
Cheers!
AsimSame in JDialog:-
       dialog.addWindowListener(new java.awt.event.WindowAdapter()
            public void windowClosing(java.awt.event.WindowEvent evt)
                // Your code over here.
        });Debopam.

JDialog close event

hello,
I have a JDialog that opens when a button is clicked. the dialog has the usual close button decoration and it has cancel and ok buttons.
when the user closes via the decoration, my windowlistener captures the close and does what it needs to do.
when the user closes via either of my buttons (both call dispose()) the windowlistener doesnt get notified. if i use an obersver/observable relationship, i can certainly capture the button actions but i wont be able to capture the close via decoration.
my question is how do i capture both without implementing both a windowlistener and the observer/observable relationship? is there something else i can call in my cancel action besides dispose that will fire a window event? i dont really care which avenue i take i just think its kinda messy to implement both to get the same result (notification that the window has closed).
thanks,

Generate a windowClosing event by adding this to the ActionListener (as suggest by DrLaszloJamf):
Window window = SwingUtilities.windowForComponent( (Component)e.getSource() );
WindowEvent windowClosing = new WindowEvent(window, WindowEvent.WINDOW_CLOSING);
Toolkit.getDefaultToolkit().getSystemEventQueue().postEvent(windowClosing);

Item Details - Event for 'Create', 'Close' buttons - possible?

Hi Friends,
I am looking for EPCF Events for Item Details iView. I am able to show the record in this iview by selectIdHandler. Now, i want to clear the iView content - the functionality when we click 'Close' button.
So, does any one of you know any Events to fire Create, Close buttons on Item Details iView?
Thanks,
Raags

Hello Raags,
Have you discovered how to trigger any of those events? I'm having a similar issue.
I need when I open the record to have it in Edit mode already, not to click the Edit button in order to get there.
Let me know if you discovered a solution.
Best regards,
Boris

Browser close button / unload event

Hi,
In Ie8 session is carrying when i close the browser using X button. Is there any way to capture this browser close button or any portal unload event.
Thanks
Manu

There is no clean way to do this. The only way i know of is to have a private global javascript variable true/false (true = show the popup, false = show popup) where the default value is true. On every click of link / form submit where you need the popup to be suppressed , set the value as false. (you can do this using a js library which can attach events to onsubmit, onclick of all links)
However the behavior you are proposing is really , really annoying (as a user), consider your interface before implementing something like this. Valid usecases are prompting the user to save changes before leaving the page, not you are leaving the website (Thats why i typed something or closed the browser)

Which Event is invoked on clicking the Close button of AIR Window

Hello
I am trying to capture the event; which is invoked when we close the AIR window by clicking its Close button (on the top-right corner). I have tried the following; but none of them seems invoked:
Code:
newWin.stage.addEventListener(Event.CLOSING, closeHandler);
newWin.stage.addEventListener(Event.EXITING, closeHandler);
newWin.stage.addEventListener(Event.REMOVED, closeHandler);
newWin.stage.addEventListener(Event.DEACTIVATE, closeHandler);
newWin.stage.addEventListener(Event.REMOVED_FROM_STAGE, closeHandler);
The code for the said problem is something like the following:
Code:
var initOptions: NativeWindowInitOptions = new NativeWindowInitOptions();
initOptions.systemChrome = NativeWindowSystemChrome.STANDARD;
var newWin: NativeWindow = new NativeWindow(initOptions);;
newWin.stage.addEventListener(Event.CLOSING, closeHandler);
Would anybody kindly help!

I wonder, no geek came forward for rescue! I am still hopeful to get a response from Adobe AIR wizards.

How set a JDialog to let no close button on upper right?

How set a JDialog to let no close button on upper right?

a dialog is like a jframe so when u remove the upper part of it u can add a label like and other component to the frames content pane. u can create a panel which will serve as the upper label and will have a background gradient coloring (like windows frames) and an icon and any buttons u want. its a simple jpanel that u put on the upper side of the dialog. u can add a mouse listener to the panel so when the user pressed the mouse and moves it around u move the dialogs position.

Removing JDialog Close[X] button,

Hi,
Can i remove the JDialog close[X] button.
For JFrame we can remove the whole title bar, is removed by setUndecorated(true). like that i dont want to remove the whoe titlebar, only the close[X] button of the JDialog i want to remove.
If any one knows, please let me know.

That USED to work,
But on Windows 7 (Maybe Vista) it removes everything except the close button.
I fear its a new Sindows thing, where the have redone modality.
As fra as I can tell, even setDefaultCloseOperation(WindowConstants.DO_NOTHING_ON_CLOSE) fails now.
Anyone else solved this for Win 7?Please, don't resurrect old threads, and don't hijack. Create a new thread, and ask your question there.

JDialog window buttons help URGENT!!!!!!!!!!!!!!!!!!

hi all,
I have a small question, I have a JDialog all I need is to know how to get rid of those three small icon buttons at the top left corner of my Dialog i.e. close button (x), minimize button(-) and maximize button(0). I don't want any of these buttons shown on my my JDialog. Any help is appreciated.
Thanks

Basically, what the three ahead of me are trying to say is that you can either capture the events on a regular JFrame (close, minimize, maximize) or you can use a JDialog which only has the a close button, or if you like it rough, you can use a JWindow which is essentially a splash screen. Though you can subclass and do what ever you like with it. Hope that helps.

How to restrict closing the tab in tabpane after clicking the close button.

Hi all,
Greetings.
I am implementing a TabPane with different 'user form's in each Tab. And all the tabs are *'closable'*.
If the user enters some data in the form, and tries to close the tab without saving the form , i need to show a confirm dialogue box that the user should go ahead or not.
If he clicks cancel, the tab should not close.
But currently i am searching for a method something like 'setOnClosing' method for tab.
There is only tab.setOnClosed() method, which will call the event after closing the tab.
Some thing the code is like below.
tab.setOnClosed(new EventHandler<javafx.event.Event>() {
     @Override
     public void handle(javafx.event.Event e) {
        // TODO: Actions to be taken on close of tab.
           // Logic to show the confirm dialouge box.
           // if YES - close the tab
           // if NO - don't close the tab.
});But my logic is executing after closing the tab. (ofcourse, as it is on setOnClosed() ;) ). Can anyone tell me how to get control before closing the tab ?
Thanks in Advance.
Sai Pradeep Dandem.

Hi All,
Finally I managed to get the handler before closing the tab pane. :)
Though this is a bit weird work around, my requirement is fulfilled at-least.
Let me explain the workaround I did.
Tab tab = new Tab(title);
tab.setClosable(false); // This line of code makes sure that the “default” close button of the tab is not appeared.
setClosableButton(tab);Then I am setting the custom close button as a graphic to the label ( Title of the tab), and aligning that graphic position to make an effect, that it is rendered exactly at the position of “Close” button.
From this Custom Close Button, I am handling the events and if confirmed I am closing the tab manually, by calling the closeTab() method in the TabPaneBehavior class.
Below is the code that is implemented as per the above logic.
      * Method to set the custom Closable Button to the given tab.
      * @param tab - Tab
     private void setClosableButton(final Tab tab,final boolean closeCheck){
          final StackPane closeBtn = new StackPane(){
               @Override
               protected void layoutChildren() {
                    super.layoutChildren();
                    // Setting the orientation of graphic(button) to the right side.
                    ((Label)((LabelSkin)getParent()).getSkinnable()).setStyle("-fx-content-display:right;");
          closeBtn.getStyleClass().setAll(new String[] { "tab-close-button" });
          closeBtn.setStyle("-fx-cursor:hand;");
          closeBtn.setPadding(new Insets(0,7,0,7));
          closeBtn.visibleProperty().bind(tab.selectedProperty());
          final EventHandler<ActionEvent> closeEvent = new EventHandler<ActionEvent>() {
               @Override
               public void handle(ActionEvent paramT) {
                    ((TabPaneSkin)TabPaneComponent.this.getSkin()).getBehavior().closeTab(tab);
          // Handler for the close button.
          closeBtn.setOnMouseReleased(new EventHandler<MouseEvent>() {
               @Override
               public void handle(MouseEvent paramT) {
                    // My logic to handle the close event or not.
                                if( logic satisfied){
                         closeEvent.handle(null);
                                }else{
                                       // Dont close the tab.
          // Showing the close button if the tab is selected.
          tab.selectedProperty().addListener(new ChangeListener<Boolean>() {
               @Override
               public void changed(ObservableValue<? extends Boolean> paramObservableValue,Boolean paramT1, Boolean isSelected) {
                    if(isSelected){
                         tab.setGraphic(closeBtn);
                    }else{
                         tab.setGraphic(null);
     }There are some drawbacks in the above code. In practice, it is suggested not to use the classes (*LabelSkin* & TabPaneSkin) that are in com.sun.javafx package. But I couldn’t get a better solution other than using those classes. And another one is I could'nt set the actual graphic for tab, as i am already using that graphic property to show the close button.
I would like to thank Narayan, for giving some inputs which has helped me to think and get the above solution. :)

JTabbedPane with one close button for all tabs

Hello,
there have several solutions been posted for JTabbedPane subclasses that provide tabs with icons working as close buttons on each tab. I think this is not user friendly because the user can hit the close button accidentally when selecting a tab. And a "really close?" dialog is clumsy.
Therefore I prefer the Netscape browser style: There's only one close button rightmost of the tabs that closes the selected tab. But I don't have an idea how to achieve this.
Does anyone have a solution or an idea? Thanks in advance for help.

This solution has been posted several times and is not what I wanted. But I rewrote the thing so that
- the close buttons are on the right hand side of each tab so that it is conformant with Eclipse style, and
- the close buttons work only with a left click (see code below).
I just wonder how I can move the text a little bit to the left so that the appearence is a bit more balanced. Can someone help, please?

Disable/enable window close button?

I have a new Window() open and I want to disable the close button when the window has already been opened. Does anyone know how to do this in Flex?

Ok I got, it's an AIR app.
You can listen to event Closing and preventDefault on it. Check this:
<?xml version="1.0" encoding="utf-8"?>

                       xmlns:s="library://ns.adobe.com/flex/spark"

                       closing="closingHandler(event)">
<fx:Script>
            <![CDATA[
                protected function closingHandler(event:Event):void
                    if(!forceClose.selected)
                            event.preventDefault();

It's still not really clear what you want to do here. Do you mean you want to be able to click the close (X) button while editing a field in the datagrid, but have the field remain in edit mode? I ran your example (minus charting components I don't have at home, snowed out of work and Flex Pro at the moment ) and it seems to behave "as I would expect", but maybe I just don't understand what your goal is.
Also - if you're using the close (X) button for anything other than closing a dialog... I wouldn't recommend doing so from a UI design perspective. Users will expect a 'close' button to behave as it does in other applications, to close the panel/dialog/window (not the change the view within a dialog). If you intend on using it to back out of a sub-view I'd reconsider. You may want to try a TabNavigator (lazy man's ViewStack but quite effective if it fits your application) instead of a ViewStack.
