public static final int NORMAL

Frame is in the "normal" state. This symbolic constant names a frame state with all state bits cleared.

public static final int ICONIFIED

This state bit indicates that frame is iconified.

public static final int MAXIMIZED_HORIZ

This state bit indicates that frame is maximized in the horizontal direction.

public static final int MAXIMIZED_VERT

This state bit indicates that frame is maximized in the vertical direction.

public static final int MAXIMIZED_BOTH

This state bit mask indicates that frame is fully maximized (that is both horizontally and vertically). It is just a convenience alias for MAXIMIZED_VERT | MAXIMIZED_HORIZ.

Note that the correct test for frame being fully maximized is

     (state & Frame.MAXIMIZED_BOTH) == Frame.MAXIMIZED_BOTH
 

To test is frame is maximized in some direction use

     (state & Frame.MAXIMIZED_BOTH) != 0
 

public Frame() throws HeadlessException

Constructs a new instance of Frame that is initially invisible. The title of the Frame is empty.

public Frame(GraphicsConfiguration gc)

Constructs a new, initially invisible Frame with the specified GraphicsConfiguration.

public Frame(String title) throws HeadlessException

Constructs a new, initially invisible Frame object with the specified title.

public Frame(String title, GraphicsConfiguration gc)

Constructs a new, initially invisible Frame object with the specified title and a GraphicsConfiguration.

public 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.

public String getTitle()

Gets the title of the frame. The title is displayed in the frame's border.

public void setTitle(String title)

Sets the title for this frame to the specified string.

public Image getIconImage()

Returns the image to be displayed as the icon for this frame.

This method is obsolete and kept for backward compatibility only. 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.

public MenuBar getMenuBar()

Gets the menu bar for this frame.

public void setMenuBar(MenuBar mb)

Sets the menu bar for this frame to the specified menu bar.

public boolean isResizable()

Indicates whether this frame is resizable by the user. By default, all frames are initially resizable.

public void setResizable(boolean resizable)

Sets whether this frame is resizable by the user.

public 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.NORMAL and Frame.ICONIFIED only. 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 neither Frame.NORMAL nor Frame.ICONIFIED the 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 the Toolkit.isFrameStateSupported(int) method.

If the frame is currently visible on the screen (the Window.isShowing() method returns true), the developer should examine the return value of the WindowEvent.getNewState() method of the WindowEvent received through the WindowStateListener to 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 any WindowEvent.WINDOW_STATE_CHANGED events is not guaranteed in this case also.

public 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_HORIZ and 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 the Toolkit.isFrameStateSupported(int) method.

If the frame is currently visible on the screen (the Window.isShowing() method returns true), the developer should examine the return value of the WindowEvent.getNewState() method of the WindowEvent received through the WindowStateListener to 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 any WindowEvent.WINDOW_STATE_CHANGED events is not guaranteed in this case also.

public 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.NORMAL and Frame.ICONIFIED but it only reports the iconic state of the frame, other aspects of frame state are not reported by this method.

public int getExtendedState()

Gets 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_HORIZ and MAXIMIZED_VERT.

public 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 bounds is null, accept bounds supplied by the system. If non-null you can override some of the system supplied values while accepting others by setting those fields you want to accept from system to Integer.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.

public Rectangle getMaximizedBounds()

Gets maximized bounds for this frame. Some fields may contain Integer.MAX_VALUE to indicate that system supplied values for this field must be used.

public void setUndecorated(boolean undecorated)

Disables or enables decorations for this frame.

This method can only be called while the frame is not displayable. To make this frame 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

public boolean isUndecorated()

Indicates whether this frame is undecorated. By default, all frames are initially decorated.

public void remove(MenuComponent m)

Removes the specified menu bar from this frame.

public void removeNotify()

Makes this Frame undisplayable by removing its connection to its native screen resource. Making a Frame undisplayable will cause any of its children to be made undisplayable. This method is called by the toolkit internally and should not be called directly by programs.

protected String paramString()

Returns a string representing the state of this Frame. 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 be null.

@Deprecated public void setCursor(int cursorType)

Sets the cursor for this frame to the specified type.

public static Frame[] getFrames()

Returns an array of all Frames created by this application. If called from an applet, the array includes only the Frames accessible by that applet.

Warning: this method may return system created frames, such as a shared, hidden frame which is used by Swing. Applications should not assume the existence of these frames, nor should an application assume anything about these frames such as component positions, LayoutManagers or serialization.

Note: To obtain a list of all ownerless windows, including ownerless Dialogs (introduced in release 1.6), use Window.getOwnerlessWindows.

public AccessibleContext getAccessibleContext()

Gets the AccessibleContext associated with this Frame. For frames, the AccessibleContext takes the form of an AccessibleAWTFrame. A new AccessibleAWTFrame instance is created if necessary.
