public class Dialog extends Window

A Dialog is a top-level window with a title and a border that is typically used to take some form of input from the user. The size of the dialog includes any area designated for the border. The dimensions of the border area can be obtained using the getInsets method, however, since these dimensions are platform-dependent, a valid insets value cannot be obtained until the dialog is made displayable by either calling pack or show. Since the border area is included in the overall size of the dialog, the border effectively obscures a portion of the dialog, constraining the area available for rendering and/or displaying subcomponents to the rectangle which has an upper-left corner location of (insets.left, insets.top), and has a size of width - (insets.left + insets.right) by height - (insets.top + insets.bottom).

The default layout for a dialog is BorderLayout.

A dialog may have its native decorations (i.e. Frame & Titlebar) turned off with setUndecorated. This can only be done while the dialog is not displayable.

A dialog may have another window as its owner when it's constructed. When the owner window of a visible dialog is minimized, the dialog will automatically be hidden from the user. When the owner window is subsequently restored, the dialog is made visible to the user again.

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

A dialog can be either modeless (the default) or modal. A modal dialog is one which blocks input to some other top-level windows in the application, except for any windows created with the dialog as their owner. See AWT Modality specification for details.

Dialogs are capable of generating the following WindowEvents: WindowOpened, WindowClosing, WindowClosed, WindowActivated, WindowDeactivated, WindowGainedFocus, WindowLostFocus.

Method Details
- addNotify
  
  public void addNotify()
  
  Makes this Dialog displayable by connecting it to a native screen resource. Making a dialog displayable will cause any of its children to be made displayable. This method is called internally by the toolkit and should not be called directly by programs.
  
  Overrides:
  
  addNotify in class Window
  
  See Also:
  
  Component.isDisplayable(), Container.removeNotify()
- isModal
  
  public boolean isModal()
  
  Indicates whether the dialog is modal.
  This method is obsolete and is kept for backwards compatibility only. Use getModalityType() instead.
  
  Returns:
  
  true if this dialog window is modal; false otherwise
  
  See Also:
  
  DEFAULT_MODALITY_TYPE, Dialog.ModalityType.MODELESS, setModal(boolean), getModalityType(), setModalityType(java.awt.Dialog.ModalityType)
- setModal
  
  public void setModal(boolean modal)
  
  Specifies whether this dialog should be modal.
  This method is obsolete and is kept for backwards compatibility only. Use setModalityType() instead.
  Note: changing modality of the visible dialog may have no effect until it is hidden and then shown again.
  
  Parameters:
  
  modal - specifies whether dialog blocks input to other windows when shown; calling to setModal(true) is equivalent to setModalityType(Dialog.DEFAULT_MODALITY_TYPE), and calling to setModal(false) is equivalent to setModalityType(Dialog.ModalityType.MODELESS)
  
  Since:
  
  1.1
  
  See Also:
  
  DEFAULT_MODALITY_TYPE, Dialog.ModalityType.MODELESS, isModal(), getModalityType(), setModalityType(java.awt.Dialog.ModalityType)
- getModalityType
  
  public Dialog.ModalityType getModalityType()
  
  Returns the modality type of this dialog.
  
  Returns:
  
  modality type of this dialog
  
  Since:
  
  1.6
  
  See Also:
  
  setModalityType(java.awt.Dialog.ModalityType)
- setModalityType
  
  public void setModalityType(Dialog.ModalityType type)
  
  Sets the modality type for this dialog. See ModalityType for possible modality types.
  If the given modality type is not supported, MODELESS is used. You may want to call getModalityType() after calling this method to ensure that the modality type has been set.
  Note: changing modality of the visible dialog may have no effect until it is hidden and then shown again.
  
  Parameters:
  
  type - specifies whether dialog blocks input to other windows when shown. null value and unsupported modality types are equivalent to MODELESS
  
  Throws:
  
  SecurityException - if the calling thread does not have permission to create modal dialogs with the given modalityType
  
  Since:
  
  1.6
  
  See Also:
  
  getModalityType(), Toolkit.isModalityTypeSupported(java.awt.Dialog.ModalityType)
- getTitle
  
  public String getTitle()
  
  Gets the title of the dialog. The title is displayed in the dialog's border.
  
  Returns:
  
  the title of this dialog window. The title may be null.
  
  See Also:
  
  setTitle(java.lang.String)
- setTitle
  
  public void setTitle(String title)
  
  Sets the title of the Dialog.
  
  Parameters:
  
  title - the title displayed in the dialog's border; a null value results in an empty title
  
  See Also:
  
  getTitle()
- setVisible
  
  public void setVisible(boolean b)
  
  Shows or hides this Dialog depending on the value of parameter b.
  Overrides:
  
  setVisible in class Window
  
  Parameters:
  
  b - if true, makes the Dialog visible, otherwise hides the Dialog. If the dialog and/or its owner are not yet displayable, both are made displayable. The dialog will be validated prior to being made visible. If false, hides the Dialog and then causes setVisible(true) to return if it is currently blocked.
  Notes for modal dialogs.
  
  setVisible(true): If the dialog is not already visible, this call will not return until the dialog is hidden by calling setVisible(false) or dispose.
  setVisible(false): Hides the dialog and then returns on setVisible(true) if it is currently blocked.
  It is OK to call this method from the event dispatching thread because the toolkit ensures that other events are not blocked while this method is blocked.
  
  See Also:
  
  Window.setVisible(boolean), Window.dispose(), Component.isDisplayable(), Component.validate(), isModal()
- show
  
  @Deprecated public void show()
  
  Deprecated.
  As of JDK version 1.5, replaced by setVisible(boolean).
  
  Makes the Dialog visible. If the dialog and/or its owner are not yet displayable, both are made displayable. The dialog will be validated prior to being made visible. If the dialog is already visible, this will bring the dialog to the front.
  If the dialog is modal and is not already visible, this call will not return until the dialog is hidden by calling hide or dispose. It is permissible to show modal dialogs from the event dispatching thread because the toolkit will ensure that another event pump runs while the one which invoked this method is blocked.
  
  Overrides:
  
  show in class Window
  
  See Also:
  
  Component.hide(), Component.isDisplayable(), Component.validate(), isModal(), Window.setVisible(boolean)
- hide
  
  @Deprecated public void hide()
  
  Deprecated.
  As of JDK version 1.5, replaced by setVisible(boolean).
  
  Hides the Dialog and then causes show to return if it is currently blocked.
  
  Overrides:
  
  hide in class Window
  
  See Also:
  
  Window.show(), Window.dispose(), Window.setVisible(boolean)
- toBack
  
  public void toBack()
  
  If this Window is visible, sends this Window to the back and may cause it to lose focus or activation if it is the focused or active Window.
  Places this Window at the bottom of the stacking order and shows it behind any other Windows in this VM. No action will take place is this Window is not visible. Some platforms do not allow Windows which are owned by other Windows to appear below their owners. Every attempt will be made to move this Window as low as possible in the stacking order; however, developers should not assume that this method will move this Window below all other windows in every situation.
  Because of variations in native windowing systems, no guarantees about changes to the focused and active Windows can be made. Developers must never assume that this Window is no longer the focused or active Window until this Window receives a WINDOW_LOST_FOCUS or WINDOW_DEACTIVATED event. On platforms where the top-most window is the focused window, this method will probably cause this Window to lose focus. In that case, the next highest, focusable Window in this VM will receive focus. On platforms where the stacking order does not typically affect the focused window, this method will probably leave the focused and active Windows unchanged.
  If this dialog is modal and blocks some windows, then all of them are also sent to the back to keep them below the blocking dialog.

- isResizable
  
  public boolean isResizable()
  
  Indicates whether this dialog is resizable by the user. By default, all dialogs are initially resizable.
  
  Returns:
  
  true if the user can resize the dialog; false otherwise.

  setResizable(boolean)
- setResizable
  
  public void setResizable(boolean resizable)
  
  Sets whether this dialog is resizable by the user.
  
  Parameters:
  
  resizable - true if the user can resize this dialog; false otherwise.

  isResizable()
- setUndecorated
  
  public void setUndecorated(boolean undecorated)
  
  Disables or enables decorations for this dialog.
  This method can only be called while the dialog is not displayable. To make this dialog decorated, it must be opaque and have the default shape, otherwise the IllegalComponentStateException will be thrown. Refer to Window.setShape(java.awt.Shape), Window.setOpacity(float) and Window.setBackground(java.awt.Color) for details
  
  Parameters:
  
  undecorated - true if no dialog decorations are to be enabled; false if dialog decorations are to be enabled
  
  Throws:
  
  IllegalComponentStateException - if the dialog is displayable
  
  IllegalComponentStateException - if undecorated is false, and this dialog does not have the default shape
  
  IllegalComponentStateException - if undecorated is false, and this dialog opacity is less than 1.0f
  
  IllegalComponentStateException - if undecorated is false, and the alpha value of this dialog background color is less than 1.0f
