JDialog (Java SE 15 & JDK 15) (original) (raw)

All Implemented Interfaces:

[ImageObserver](../../java/awt/image/ImageObserver.html "interface in java.awt.image"), [MenuContainer](../../java/awt/MenuContainer.html "interface in java.awt"), [Serializable](../../../java.base/java/io/Serializable.html "interface in java.io"), [Accessible](../accessibility/Accessible.html "interface in javax.accessibility"), [RootPaneContainer](RootPaneContainer.html "interface in javax.swing"), [WindowConstants](WindowConstants.html "interface in javax.swing")

@JavaBean(defaultProperty="JMenuBar", description="A toplevel window for creating dialog boxes.") public class JDialog extends Dialog implements WindowConstants, Accessible, RootPaneContainer

The main class for creating a dialog window. You can use this class to create a custom dialog, or invoke the many class methods in JOptionPane to create a variety of standard dialogs. For information about creating dialogs, see_The Java Tutorial_ sectionHow to Make Dialogs.

The JDialog component contains a JRootPane as its only child. The contentPane should be the parent of any children of theJDialog. As a convenience, the add, remove, and setLayout methods of this class are overridden, so that they delegate calls to the corresponding methods of the ContentPane. For example, you can add a child component to a dialog as follows:

   dialog.add(child);

And the child will be added to the contentPane. The contentPane is always non-null. Attempting to set it to null generates an exception. The default contentPane has a BorderLayout manager set on it. Refer to RootPaneContainer for details on adding, removing and setting the LayoutManager of a JDialog.

Please see the JRootPane documentation for a complete description of the contentPane, glassPane, and layeredPane components.

In a multi-screen environment, you can create a JDialog on a different screen device than its owner. See Frame for more information.

Warning: Swing is not thread safe. For more information see Swing's Threading Policy.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans has been added to the java.beans package. Please see XMLEncoder.

1.2

  setDefaultCloseOperation(int)

  • setDefaultCloseOperation

  @BeanProperty(preferred=true,enumerationValues={"WindowConstants.DO_NOTHING_ON_CLOSE","WindowConstants.HIDE_ON_CLOSE","WindowConstants.DISPOSE_ON_CLOSE"},description="The dialog\'s default close operation.")public void setDefaultCloseOperation​(int operation)
  Sets the operation that will happen by default when the user initiates a "close" on this dialog. You must specify one of the following choices:
  * DO_NOTHING_ON_CLOSE (defined in WindowConstants): Don't do anything; require the program to handle the operation in the windowClosing method of a registered WindowListener object.
  * HIDE_ON_CLOSE (defined in WindowConstants): Automatically hide the dialog after invoking any registered WindowListener objects.
  * DISPOSE_ON_CLOSE (defined in WindowConstants): Automatically hide and dispose the dialog after invoking any registered WindowListener objects.
  The value is set to HIDE_ON_CLOSE by default. Changes to the value of this property cause the firing of a property change event, with property name "defaultCloseOperation".
  Note: When the last displayable window within the Java virtual machine (VM) is disposed of, the VM may terminate. See AWT Threading Issues for more information.
  Parameters:
  operation - the operation which should be performed when the user closes the dialog
  Throws:
  [IllegalArgumentException](../../../java.base/java/lang/IllegalArgumentException.html "class in java.lang") - if defaultCloseOperation value isn't one of the above valid values

  • setTransferHandler

  Sets the transferHandler property, which is a mechanism to support transfer of data into this component. Use null if the component does not support data transfer operations.
  If the system property suppressSwingDropSupport is false (the default) and the current drop target on this component is eithernull or not a user-set drop target, this method will change the drop target as follows: If newHandler is null it will clear the drop target. If not null it will install a newDropTarget.
  Note: When used with JDialog, TransferHandler only provides data import capability, as the data export related methods are currently typed to JComponent.
  Please see How to Use Drag and Drop and Data Transfer, a section in_The Java Tutorial_, for more information.

  • setDefaultLookAndFeelDecorated

  public static void setDefaultLookAndFeelDecorated​(boolean defaultLookAndFeelDecorated)
  Provides a hint as to whether or not newly created JDialogs should have their Window decorations (such as borders, widgets to close the window, title...) provided by the current look and feel. If defaultLookAndFeelDecorated is true, the current LookAndFeel supports providing window decorations, and the current window manager supports undecorated windows, then newly created JDialogs will have their Window decorations provided by the current LookAndFeel. Otherwise, newly created JDialogs will have their Window decorations provided by the current window manager.
  You can get the same effect on a single JDialog by doing the following:
  JDialog dialog = new JDialog();
  dialog.setUndecorated(true);
  dialog.getRootPane().setWindowDecorationStyle(JRootPane.PLAIN_DIALOG);

  Parameters:
  defaultLookAndFeelDecorated - A hint as to whether or not current look and feel should provide window decorations
  Since:
  1.4
  See Also:
  LookAndFeel.getSupportsWindowDecorations()

  • isDefaultLookAndFeelDecorated

  public static boolean isDefaultLookAndFeelDecorated()
  Returns true if newly created JDialogs should have their Window decorations provided by the current look and feel. This is only a hint, as certain look and feels may not support this feature.
  Returns:
  true if look and feel should provide Window decorations.
  Since:
  1.4
