public class Dialog extends Window
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
.

public void toBack()
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.

The opacity value is in the range [0..1]. Note that setting the opacity level of 0 may or may not disable the mouse event handling on this window. This is a platform-dependent behavior.
The following conditions must be met in order to set the opacity value
less than 1.0f
:
TRANSLUCENT
translucency must be supported by the underlying system
Frame.setUndecorated(boolean)
and setUndecorated(boolean)
)
GraphicsDevice.setFullScreenWindow(Window)
)
If the requested opacity value is less than 1.0f
, and any of the
above conditions are not met, the window opacity will not change,
and the IllegalComponentStateException
will be thrown.
The translucency levels of individual pixels may also be effected by the
alpha component of their color (see Window.setBackground(Color)
) and the
current shape of this window (see Window.setShape(Shape)

public void setShape(Shape shape)
Setting a shape cuts off some parts of the window. Only the parts that
belong to the given Shape
remain visible and clickable. If
the shape argument is null
, this method restores the default
shape, making the window rectangular on most platforms.
The following conditions must be met to set a non-null shape:
PERPIXEL_TRANSPARENT
translucency must be supported by the
underlying system
Frame.setUndecorated(boolean)
and setUndecorated(boolean)
)
GraphicsDevice.setFullScreenWindow(Window)
)
If the requested shape is not null
, and any of the above
conditions are not met, the shape of this window will not change,
and either the UnsupportedOperationException
or IllegalComponentStateException
will be thrown.
The tranlucency levels of individual pixels may also be effected by the
alpha component of their color (see Window.setBackground(Color)
) and the
opacity value (see Window.setOpacity(float)
). See GraphicsDevice.WindowTranslucency
for more details.

public void setBackground(Color bgColor)
If the windowing system supports the PERPIXEL_TRANSLUCENT
tranclucency, the alpha component of the given background color
may effect the mode of operation for this window: it indicates whether
this window must be opaque (alpha equals 1.0f
) or per-pixel translucent
(alpha is less than 1.0f
). If the given background color is
null
, the window is considered completely opaque.
All the following conditions must be met to enable the per-pixel transparency mode for this window:
PERPIXEL_TRANSLUCENT
translucency must be supported by the graphics
device where this window is located
Frame.setUndecorated(boolean)
and setUndecorated(boolean)
)
GraphicsDevice.setFullScreenWindow(Window)
)
If the alpha component of the requested background color is less than
1.0f
, and any of the above conditions are not met, the background
color of this window will not change, the alpha component of the given
background color will not affect the mode of operation for this window,
and either the UnsupportedOperationException
or IllegalComponentStateException
will be thrown.
When the window is per-pixel translucent, the drawing sub-system
respects the alpha value of each individual pixel. If a pixel gets
painted with the alpha color component equal to zero, it becomes
visually transparent. If the alpha of the pixel is equal to 1.0f, the
pixel is fully opaque. Interim values of the alpha color component make
the pixel semi-transparent. In this mode, the background of the window
gets painted with the alpha value of the given background color. If the
alpha value of the argument of this method is equal to 0
, the
background is not painted at all.
The actual level of translucency of a given pixel also depends on window
opacity (see Window.setOpacity(float)
), as well as the current shape of
this window (see Window.setShape(Shape)
).
Note that painting a pixel with the alpha value of 0
may or may
not disable the mouse event handling on this pixel. This is a
platform-dependent behavior. To make sure the mouse events do not get
dispatched to a particular pixel, the pixel must be excluded from the
shape of the window.
Enabling the per-pixel translucency mode may change the graphics configuration of this window due to the native platform requirements.
