Application close icon ('X')
Greetings all,
I am new to this forum and relatively new to Java.
I would like to bind a member function to the application close icon (The 'X' in the upper right hand corner of the applications main window).
Does anyone know how to do this?
Thanks.

I would like to bind a member function to the
application close icon (The 'X' in the upper right
hand corner of the applications main window).
Does anyone know how to do this?Create a WindowAdapter and override the windowClosing event to call the method you want. Then do
Window w = ...
w.addWindowListener(myListener);

hi,
I have one problem now. I tried to make 'X' (Close) icon work (i.e. the dialog window should be closed whenever clicking 'X' icon). I use:
setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE);
but it does not work. Anybody could help me solve this problem? Thanks a lot.
JrabiWell, it is a part of a large project.

Why do applications close suddenly ?
I have lots of questions regarding my IPAD. Any help?
Why do applications close suddenly ?
The messages are not working or how can i use it?
The engine is slow
I want to download the office ( Word and Excel ) what is the programme name?In order...
Close all your applications. Double tap the Home button to display the multi-tasking bar. Tap and hol one of the icons IN THAT BAR. Tap the red circle with a line through it to close those apps. Always do this when you are closing apps you are not actively using. Check out a video if it is still not clear.
Messages on iPad is not SMS if that is what you mean. You need an Apple ID and iCloud account to send iMessages to other Apple iOS device users from iPad. See more information here.
The original iPad is much slower compared to new devices - just like computers. Technology moves very fast these days. Other than upgrade, there is really nothing you can do about it being slow.
Microsoft makes a native Office iOS application for iPad, but it is usable only for subscribers to their Office 365 service and required iOS 6.1 or later. There are several third-party options that you can find in the iTunes App Store. -
Hide close icon from taskflow inline popups / process window closure
Hi OTN,
I would like to know of there is an opportunity to hide "X" close icon from popup window when I run a taskflow in a popup as an inlineDocument?
Or what is a preferred way to process user window closure to rollback changes?
In my current application a user always has Cancel button which sets taskflow return parameter as "Cancel" which is then read by dialog return listener.
The listener would call Rollback if there is "Cancel" returned.
But "X" close doesn't set any parameter.
Maybe I sould set "Cancel" as a default return parameter value? Or the right way is to use finalizer?
Please, advice me.
Thanks.
ADF Fusion Web Application
JDev 11.1.1.3You have to define and apply a custom skin. It is easy, read the documentation here:
http://download.oracle.com/docs/cd/E14571_01/web.1111/b31973/af_skin.htm#BAJFEFCJ
You can get detailed description of all the supported skin selectors here:
http://download.oracle.com/docs/cd/E14571_01/apirefs.1111/e15862/toc.htm#ComponentLevelSelectors
Note, that <tt>af|dialog::close-icon-style {display:none;}</tt> will affect all the popup dialogs, but not only the taskflow popup windows. If you need to apply it only to taskflow popup windows, then use <tt>af|panelWindow::close-icon-style{ display:none; }</tt>. Have a look at Frank's blog post http://blogs.oracle.com/jdevotnharvest/2010/12/how-to_hide_the_close_icon_for_task_flows_opened_in_dialogs.html.

Capture Close icon event for ADF dynamic UI shell
I am using Oracle ADF dynamic TAB UI shell template to build
the application.
I have two option to close Employee TAB on right side , one
is “Remove Tab” highlighted in Navigation pane and second is close icon in
right most corner of tab page.
Now while closing the tab page I want to invoke one method
or task. In Remove Tab I am able to do this by managed Bean (writing the
method into bean and invoke that method in Command link of Navigation pane).
But here the challenge is to invoke same method while
closing the Tab by close icon. Therefore I want to capture the event and call
this method.
Please let me know if you can share any idea on this.
When clicked on Remove tab I am getting popup message
successfully while changing the name SMITHR from RITESH.Hi,
In this thread you have some ideas
UI Shell - how to allow ADF Library Bounded Task Flow to close itself -
When surfing or working on my iPad mini, frequently my applications close and it goes the home screen. This problem started about a week ago. I did do a hard reset.
Make sure you do not leave a lot of apps open in the iOS multitasking bar.
Dbl click the Home button, look to see now many apps that are still active in the multitask bar.
You can safely quit some of these by holding your finger on one app until all the icons wiggle.
Tap the red dash in the upper left corner to quit each app from running. Then just tap anywhere else on the iPad's screen or single click the Home button to stop the wiggling and close the Multitask bar.
Good Luck! -
Error copying application.xml icons: .../bin-release/assets/icons' does not exist
Hi,
Whenever I try to export the release build I get error from COmpiler during the process that "Error copying application.xml icons: Resource '/Project_Name/bin-release/assets/icons' does not exist." I have specified 4 icons in the -app.xml file of sizes 16,32,48,128 which exist in the path specified and files are not corrupt. I have checked and unchecked the compiler directive "Copy non-embedded resources in the Output file" but that has not helped too.
Can somebody please advise what do I do in this situation?
We are using
FB4 with Flex Hero(4.5) SDK and java heap space specified in .ini files is 1224m
This is somewhat urgent guys...
Thanks
ShubhraFrank,
Thank you for your answer. I had not checked (will do so tonight).
I had considered it adequate to wipe out the entire system directory (thereby wiping out the integrated weblogic server), but perhaps it was not adequate? I did not specify that this is on the integrated server, but that is the case....

How to handle the "cancel" button and "close" icon of a popup ?
Hi,
I have a popup with "cancel button" and "close icon"(on the top right corner of the popup), I want the same operations to be performed on clicking of any of these two components.
Is there a way to handle such situation ?
I read about 2 cases to look into this but they didn't work too well for me.
1. I read about the "popcancellistener" but that listener is called whenever the popup closes, so suppose I have an "ok button" on the popup to create a record, after the record is created, the popup closes and goes into the "popcancellistener", now the question is "how do we know if it came there because of the 'ok button' or 'some other event'".
2. I even checked the "DialogListener", now I'm able to distinguish between the 'OK' and 'CANCEL' button in the dialoglistener using the "Dialog.Outcome.ok/cancel", but when a user clicks on the close icon, we do not enter the "DialogListener" at all, so in this case "how do we handle the close icon click event"
Do let me know if you need any more information from my side.
Thanks for the help in advance.The following mechanism responds to any of the following events: <Esc> key, Close icon ('x'), Cancel button
JavaScript part:
function popupClosedListener(event){
var source = event.getSource();
var popupId = source.getClientId();
var params = {};
params['popupId'] = popupId;
var type = "serverPopupClosed";
var immediate = true;
AdfCustomEvent.queue(source, type, params, immediate);
}JSF part:
<af:popup ....>
<af:clientListener method="popupClosedListener"
type="popupClosed"/>
<af:serverListener type="serverPopupClosed"
method="#{myBean.serverPopupClosedMetod}"/>
</af:popup>Finally, Java part:
public void serverPopupClosedMetod(ClientEvent event){

So, I have created a cool project that was a lot of hard work in After Effects CC (Mac), While rendering a project in After Effects CC (Mac) , the application closes half way, saying it quit unexpectedly. Here is the link to an error log which is automatically recorded when After Effects crashes:- After Effects Crash (Mac) - Pastebin.com
I have tried to render this project at least 5 times, shutting and restarting my computer. Please Help!
Here is my computer specs if needed;
Operating System: Mac OS X Mavericks version 10.9.4 (13E28)
Processor: 2.5GHz Intel Core i5
Memory: 4GB 1600 MHz DDR3
Graphics: Intel HD Graphics 4000
Screen Resolution: 13-inch (1280 x 800)
Hard Drive: 500GB -- 186.49 GB free space.
Thanks
MilanElement 3d renders using your graphics card. Unlike After Effects, what GPU you're using matters a lot for Element.
As it is, you don't really have one.
You could try rendering an image sequence and then picking up your render where it left off when it crashes, but if a certain frame is just too much for your computer to handle, there's not much we can help with. I'd suggest adding a GPU that Element can use. -
Application builder icon disappeared from database home page
i am wondering , is APPLICATION BUILDER ICON removed from database home page of all users or just mine. please i need help here..
Do you mean the icon display, or the ability to use the app identified by the icon?
(If just the display (it shows the empty box), there is a known problem with some images appearing broken. In which case, you can try forcing a reload form the server by adding a 'Shift' to your reload command (eg: use Shift-F5 in I.E. or Shift-Ctrl-R in Firefox) -
Disable close icon on title bar
Is it possible to disable the close icon on the title bar (right hand corner) in a swing window?
Fai.Example:
frameNameHere.setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);
There is also the option to take away the "window-frame" alltogether with:
frameNameHere.setUndecorated(true);
Though if you do that you should probably use the "DO_NOTHING_ON_CLOSE" anyway, since otherwise it can still be closed with Alt F4 for instance. -
Help with disabling close icon of last opened tab in JTabbedPane
Hello
Would someone help me out ? I have 3 tabs opened in a JTabbedPane, each with close icon "X". I am looking for a way to tell my program: if the user closes 2 tabs and only 1 remain, disable the close icon "X" of the last opened tab so that the user is unable to close the last tab. I have searched the forum, most I have run into are how to create the close icon. Would someone give me some insight into how to go about doing this? or if you have come across a forum that discusses this, do please post the link. Also, I am using java 1.6.
Thanks very much in advanceOn each close, look how many tabs are remaining open in the JTabbedPane (getTabCount).
If there is only one left, set its close button to invisible. Something like this:
if (pane.getTabCount() == 1) {
TabCloseButton tcb = (TabCloseButton) pane.getTabComponentAt(0);
tcb.getBtClose().setVisible(false);
} -
Ok, so I was trying to get a JTabbedPane with 'X' icons on each tab. Searched this site, and found no answers, but loads of questions on how to do it. I've done it now, and here's my code.
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
* A JTabbedPane which has a close ('X') icon on each tab.
* To add a tab, use the method addTab(String, Component)
* To have an extra icon on each tab (e.g. like in JBuilder, showing the file type) use
* the method addTab(String, Component, Icon). Only clicking the 'X' closes the tab.
public class JTabbedPaneWithCloseIcons extends JTabbedPane implements MouseListener {
public JTabbedPaneWithCloseIcons() {
super();
addMouseListener(this);
public void addTab(String title, Component component) {
this.addTab(title, component, null);
public void addTab(String title, Component component, Icon extraIcon) {
super.addTab(title, new CloseTabIcon(extraIcon), component);
public void mouseClicked(MouseEvent e) {
int tabNumber=getUI().tabForCoordinate(this, e.getX(), e.getY());
if (tabNumber < 0) return;
Rectangle rect=((CloseTabIcon)getIconAt(tabNumber)).getBounds();
if (rect.contains(e.getX(), e.getY())) {
//the tab is being closed
this.removeTabAt(tabNumber);
public void mouseEntered(MouseEvent e) {}
public void mouseExited(MouseEvent e) {}
public void mousePressed(MouseEvent e) {}
public void mouseReleased(MouseEvent e) {}
* The class which generates the 'X' icon for the tabs. The constructor
* accepts an icon which is extra to the 'X' icon, so you can have tabs
* like in JBuilder. This value is null if no extra icon is required.
class CloseTabIcon implements Icon {
private int x_pos;
private int y_pos;
private int width;
private int height;
private Icon fileIcon;
public CloseTabIcon(Icon fileIcon) {
this.fileIcon=fileIcon;
width=16;
height=16;
public void paintIcon(Component c, Graphics g, int x, int y) {
this.x_pos=x;
this.y_pos=y;
Color col=g.getColor();
g.setColor(Color.black);
int y_p=y+2;
g.drawLine(x+1, y_p, x+12, y_p);
g.drawLine(x+1, y_p+13, x+12, y_p+13);
g.drawLine(x, y_p+1, x, y_p+12);
g.drawLine(x+13, y_p+1, x+13, y_p+12);
g.drawLine(x+3, y_p+3, x+10, y_p+10);
g.drawLine(x+3, y_p+4, x+9, y_p+10);
g.drawLine(x+4, y_p+3, x+10, y_p+9);
g.drawLine(x+10, y_p+3, x+3, y_p+10);
g.drawLine(x+10, y_p+4, x+4, y_p+10);
g.drawLine(x+9, y_p+3, x+3, y_p+9);
g.setColor(col);
if (fileIcon != null) {
fileIcon.paintIcon(c, g, x+width, y_p);
public int getIconWidth() {
return width + (fileIcon != null? fileIcon.getIconWidth() : 0);
public int getIconHeight() {
return height;
public Rectangle getBounds() {
return new Rectangle(x_pos, y_pos, width, height);
}You can also specify an extra icon to put on each tab. Read my comments on how to do it.With the following code you'll be able to have use SCROLL_TAB_LAYOUT and WRAP_TAB_LAYOUT. With setCloseIcons() you'll be able to set images for the close-icons.

hello,
i have a problem with event KEY-EXIT
this event doesn't include the CLOSE icon (right top of all windows)
and users can exit without execute the code in KEY-EXIT event
in fact KEY-EXIT is trigger only by the icon exit in the tool bar
How can I trigger my code on system CLOSE icon????
Thanks for your help
@Rosagio
I work under designer 9i who generate forms 9iKEY-EXIT triggers fires only when the "Key" associated with the trigger is pressed or DO_KEY('EXIT_FORM') is executed.
You can use the WHEN-WINDOW-CLOSED trigger on your window and after you finish the standard processing you have (or not) issue a DO_KEY('EXIT_FORM'); this will simulate the EXIT key bein pressed.

Inline popup - close icon null pointer issue
Hi all,
I have a taskflow which is opened as inline popup dialog. Taskflow is in pageFlowScope.
The popup has OK, Cancel. On click of OK and Cancel of dialog it returns a value.
However when I click on Close icon "x" of dialog and return to the calling parent window and try to get the any iterator from the binding container, the iterators are all null.
I am missing something in my configuration.
Thanks
AjayHi,
actually clicking teh 'x' does nothing than closing the dialog.
However when I click on Close icon "x" of dialog and return to the calling parent window and try to get the any iterator from the binding container, the iterators are all null.
What is the code you use and where and when do you call this code ? And what JDeveloper version are you working with ?
