Class Dialog
- All Implemented Interfaces:
- ImageObserver,- MenuContainer,- Serializable,- Accessible
- Direct Known Subclasses:
- FileDialog,- JDialog
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- 
addNotifypublic 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.
- 
isModalpublic boolean isModal()Indicates whether the dialog is modal.This method is obsolete and is kept for backwards compatibility only. Use getModalityType()instead.- Returns:
- trueif this dialog window is modal;- falseotherwise
- See Also:
 
- 
setModalpublic void setModal(boolean modal) Specifies whether this dialog should be modal.This method is obsolete and is kept for backwards compatibility only.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:
 
- 
getModalityTypeReturns the modality type of this dialog.- Returns:
- modality type of this dialog
- Since:
- 1.6
- See Also:
 
- 
setModalityTypeSets the modality type for this dialog. SeeModalityTypefor possible modality types.If the given modality type is not supported, MODELESSis used. You may want to callgetModalityType()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.- nullvalue and unsupported modality types are equivalent to- MODELESS
- Since:
- 1.6
- See Also:
 
- 
getTitleGets 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:
 
- 
setTitleSets 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:
 
- 
setVisiblepublic void setVisible(boolean b) Shows or hides thisDialogdepending on the value of parameterb.- Overrides:
- setVisiblein class- Window
- Parameters:
- b- if- true, makes the- Dialogvisible, 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- Dialogand 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:
 
- 
showDeprecated.As of JDK version 1.5, replaced bysetVisible(boolean).Makes theDialogvisible. 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. 
- 
hideDeprecated.As of JDK version 1.5, replaced bysetVisible(boolean).Hides the Dialog and then causesshowto return if it is currently blocked.
- 
toBackpublic 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. 
- 
isResizablepublic boolean isResizable()Indicates whether this dialog is resizable by the user. By default, all dialogs are initially resizable.- Returns:
- trueif the user can resize the dialog;- falseotherwise.
- See Also:
 
- 
setResizablepublic void setResizable(boolean resizable) Sets whether this dialog is resizable by the user.- Parameters:
- resizable-- trueif the user can resize this dialog;- falseotherwise.
- See Also:
 
- 
setUndecoratedpublic 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 IllegalComponentStateExceptionwill be thrown. Refer toWindow.setShape(java.awt.Shape),Window.setOpacity(float)andWindow.setBackground(java.awt.Color)for details- Parameters:
- undecorated-- trueif no dialog decorations are to be enabled;- falseif dialog decorations are to be enabled
- Throws:
- IllegalComponentStateException- if the dialog is displayable
- IllegalComponentStateException- if- undecoratedis- false, and this dialog does not have the default shape
- IllegalComponentStateException- if- undecoratedis- false, and this dialog opacity is less than- 1.0f
- IllegalComponentStateException- if- undecoratedis- false, and the alpha value of this dialog background color is less than- 1.0f
- Since:
- 1.4

paramStringReturns a string representing the state of this dialog. This method is intended to be used only for debugging purposes, and the content and format of the returned string may vary between implementations. The returned string may be empty but may not benull.- Overrides:
- paramStringin class- Container
- Returns:
- the parameter string of this dialog window.
 
- 
getAccessibleContextGets the AccessibleContext associated with this Dialog. For dialogs, the AccessibleContext takes the form of an AccessibleAWTDialog. A new AccessibleAWTDialog instance is created if necessary.- Specified by:
- getAccessibleContextin interface- Accessible
- Overrides:
- getAccessibleContextin class- Window
- Returns:
- an AccessibleAWTDialog that serves as the AccessibleContext of this Dialog
