 public class Frame extends Window implements MenuContainer AFrameis a top-level window with a title and a border.The size of the frame includes any area designated for the border. The dimensions of the border area may be obtained using the getInsetsmethod, however, since these dimensions are platform-dependent, a valid insets value cannot be obtained until the frame is made displayable by either callingpackorshow. Since the border area is included in the overall size of the frame, the border effectively obscures a portion of the frame, 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 ofwidth - (insets.left + insets.right)byheight - (insets.top + insets.bottom).The default layout for a frame is BorderLayout.A frame may have its native decorations (i.e. FrameandTitlebar) turned off withsetUndecorated. This can only be done while the frame is notdisplayable.In a multi-screen environment, you can create a Frameon a different screen device by constructing theFramewithFrame(GraphicsConfiguration)orFrame(String title, GraphicsConfiguration). TheGraphicsConfigurationobject is one of theGraphicsConfigurationobjects of the target screen device.In a virtual device multi-screen environment in which the desktop area could span multiple physical screen devices, the bounds of all configurations are relative to the virtual-coordinate system. The origin of the virtual-coordinate system is at the upper left-hand corner of the primary physical screen. Depending on the location of the primary screen in the virtual device, negative coordinates are possible, as shown in the following figure.   In such an environment, when calling setLocation, you must pass a virtual coordinate to this method. Similarly, callinggetLocationOnScreenon aFramereturns virtual device coordinates. Call thegetBoundsmethod of aGraphicsConfigurationto find its origin in the virtual coordinate system.The following code sets the location of the Frameat (10, 10) relative to the origin of the physical screen of the correspondingGraphicsConfiguration. If the bounds of theGraphicsConfigurationis not taken into account, theFramelocation would be set at (10, 10) relative to the virtual-coordinate system and would appear on the primary physical screen, which might be different from the physical screen of the specifiedGraphicsConfiguration.Frame f = new Frame(GraphicsConfiguration gc); Rectangle bounds = gc.getBounds(); f.setLocation(10 + bounds.x, 10 + bounds.y);Frames are capable of generating the following types of WindowEvents:- WINDOW_OPENED
- WINDOW_CLOSING:
 If the program doesn't explicitly hide or dispose the window while processing this event, the window close operation is canceled.
- WINDOW_CLOSED
- WINDOW_ICONIFIED
- WINDOW_DEICONIFIED
- WINDOW_ACTIVATED
- WINDOW_DEACTIVATED
- WINDOW_GAINED_FOCUS
- WINDOW_LOST_FOCUS
- WINDOW_STATE_CHANGED

Method Detail- 
addNotifypublic void addNotify() Makes this Frame displayable by connecting it to a native screen resource. Making a frame 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:
- addNotifyin class- Window
- See Also:
- Component.isDisplayable(),- removeNotify()
 
 - 
getTitlepublic String getTitle() Gets the title of the frame. The title is displayed in the frame's border.- Returns:

Use Window.getIconImages()instead.If a list of several images was specified as a Window's icon, this method will return the first item of the list. - Returns:
- the icon image for this frame, or nullif this frame doesn't have an icon image.
- See Also:
- Window.setIconImage(Image),- Window.getIconImages(),- Window.setIconImages(java.util.List<? extends java.awt.Image>)
 
 -

- the menu bar for this frame, or nullif this frame doesn't have a menu bar.
- See Also:
- setMenuBar(MenuBar)
 
 - 
setMenuBarpublic void setMenuBar(MenuBar mb) Sets the menu bar for this frame to the specified menu bar.- Parameters:
- mb- the menu bar being set. If this parameter is- nullthen any existing menu bar on this frame is removed.
- See Also:

 - 
setStatepublic void setState(int state) Sets the state of this frame (obsolete).In older versions of JDK a frame state could only be NORMAL or ICONIFIED. Since JDK 1.4 set of supported frame states is expanded and frame state is represented as a bitwise mask. For compatibility with applications developed earlier this method still accepts Frame.NORMALandFrame.ICONIFIEDonly. The iconic state of the frame is only changed, other aspects of frame state are not affected by this method. If the state passed to this method is neitherFrame.NORMALnorFrame.ICONIFIEDthe method performs no actions at all.Note that if the state is not supported on a given platform, neither the state nor the return value of the getState()method will be changed. The application may determine whether a specific state is supported via theToolkit.isFrameStateSupported(int)method.If the frame is currently visible on the screen (the Window.isShowing()method returnstrue), the developer should examine the return value of theWindowEvent.getNewState()method of theWindowEventreceived through theWindowStateListenerto determine that the state has actually been changed.If the frame is not visible on the screen, the events may or may not be generated. In this case the developer may assume that the state changes immediately after this method returns. Later, when the setVisible(true)method is invoked, the frame will attempt to apply this state. Receiving anyWindowEvent.WINDOW_STATE_CHANGEDevents is not guaranteed in this case also.- Parameters:
- state- either- Frame.NORMALor- Frame.ICONIFIED.
- See Also:
- setExtendedState(int),- Window.addWindowStateListener(java.awt.event.WindowStateListener)
 
 - 
setExtendedStatepublic void setExtendedState(int state) Sets the state of this frame. The state is represented as a bitwise mask.- NORMAL
 Indicates that no state bits are set.
- ICONIFIED
- MAXIMIZED_HORIZ
- MAXIMIZED_VERT
- MAXIMIZED_BOTH
 Concatenates- MAXIMIZED_HORIZand- MAXIMIZED_VERT.
 Note that if the state is not supported on a given platform, neither the state nor the return value of the getExtendedState()method will be changed. The application may determine whether a specific state is supported via theToolkit.isFrameStateSupported(int)method.If the frame is currently visible on the screen (the Window.isShowing()method returnstrue), the developer should examine the return value of theWindowEvent.getNewState()method of theWindowEventreceived through theWindowStateListenerto determine that the state has actually been changed.If the frame is not visible on the screen, the events may or may not be generated. In this case the developer may assume that the state changes immediately after this method returns. Later, when the setVisible(true)method is invoked, the frame will attempt to apply this state. Receiving anyWindowEvent.WINDOW_STATE_CHANGEDevents is not guaranteed in this case also.- Parameters:
- state- a bitwise mask of frame state constants
- Since:
- 1.4
- See Also:
- Window.addWindowStateListener(java.awt.event.WindowStateListener)
 
 - 
getStatepublic int getState() Gets the state of this frame (obsolete).In older versions of JDK a frame state could only be NORMAL or ICONIFIED. Since JDK 1.4 set of supported frame states is expanded and frame state is represented as a bitwise mask. For compatibility with old programs this method still returns Frame.NORMALandFrame.ICONIFIEDbut it only reports the iconic state of the frame, other aspects of frame state are not reported by this method.- Returns:
- Frame.NORMALor- Frame.ICONIFIED.
- See Also:
- setState(int),- getExtendedState()
 
 - 
getExtendedStatepublic int getExtendedState() Gets the state of this frame. The state is represented as a bitwise mask.- NORMAL

 - Returns:
- a bitwise mask of frame state constants
- Since:
- 1.4
- See Also:
- setExtendedState(int)
 
 - 
setMaximizedBoundspublic void setMaximizedBounds(Rectangle bounds) Sets the maximized bounds for this frame.When a frame is in maximized state the system supplies some defaults bounds. This method allows some or all of those system supplied values to be overridden. If boundsisnull, accept bounds supplied by the system. If non-nullyou can override some of the system supplied values while accepting others by setting those fields you want to accept from system toInteger.MAX_VALUE.Note, the given maximized bounds are used as a hint for the native system, because the underlying platform may not support setting the location and/or size of the maximized windows. If that is the case, the provided values do not affect the appearance of the frame in the maximized state. - Parameters:
- bounds- bounds for the maximized state
- Since:
- 1.4
- See Also:
- getMaximizedBounds()
 
 - 
getMaximizedBoundspublic Rectangle getMaximizedBounds() Gets maximized bounds for this frame. Some fields may containInteger.MAX_VALUEto indicate that system supplied values for this field must be used.- Returns:

- Since:
- 1.4
- See Also:
- setMaximizedBounds(Rectangle)
 
 - 
setUndecoratedpublic void setUndecorated(boolean undecorated) Disables or enables decorations for this frame.This method can only be called while the frame is not displayable.
