Class Overview

A Frame is 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 getInsets method, however, since these dimensions are platform-dependent, a valid insets value cannot be obtained until the frame is made displayable by either calling pack or show. 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 of width - (insets.left + insets.right) by height - (insets.top + insets.bottom).

The default layout for a frame is BorderLayout.

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

In a multi-screen environment, you can create a Frame on a different screen device by constructing the Frame with Frame(GraphicsConfiguration) or Frame(String, GraphicsConfiguration). The GraphicsConfiguration object is one of the GraphicsConfiguration objects 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.

Diagram of virtual device encompassing three physical screens and one primary physical screen. The primary physical screen
shows (0,0) coords while a different physical screen shows (-80,-100) coords.

In such an environment, when calling setLocation, you must pass a virtual coordinate to this method. Similarly, calling getLocationOnScreen on a Frame returns virtual device coordinates. Call the getBounds method of a GraphicsConfiguration to find its origin in the virtual coordinate system.

The following code sets the location of the Frame at (10, 10) relative to the origin of the physical screen of the corresponding GraphicsConfiguration. If the bounds of the GraphicsConfiguration is not taken into account, the Frame location 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 specified GraphicsConfiguration.

      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

Public Methods

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 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.

Returns

an AccessibleAWTFrame that serves as the AccessibleContext of this Frame

public int getCursorType ()

This method is deprecated.
As of JDK version 1.1, replaced by Component.getCursor().

public synchronized 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.

Returns

a bitwise mask of frame state constants

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 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.

Returns

the icon image for this frame, or null if this frame doesn't have an icon image.

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.

Returns

maximized bounds for this frame; may be null

public MenuBar getMenuBar ()

Gets the menu bar for this frame.

Returns

the menu bar for this frame, or null if this frame doesn't have a menu bar.

public synchronized 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.

Returns

Frame.NORMAL or Frame.ICONIFIED.

public String getTitle ()

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

Returns

the title of this frame, or an empty string ("") if this frame doesn't have a title.

public boolean isResizable ()

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

Returns

true if the user can resize this frame; false otherwise.

public boolean isUndecorated ()

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

Returns

true if frame is undecorated; false otherwise.

public void remove (MenuComponent m)

Removes the specified menu bar from this frame.

Parameters

m	the menu component to remove. If `m` is `null`, then no action is taken

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.

public void setCursor (int cursorType)

This method is deprecated.
As of JDK version 1.1, replaced by Component.setCursor(Cursor).

public synchronized 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, nothing will happen. The application may determine if a specific state is available via the java.awt.Toolkit.isFrameStateSupported(int state) method.

Parameters

state	a bitwise mask of frame state constants

public void setIconImage (Image image)

Sets the image to be displayed as the icon for this window.

This method can be used instead of setIconImages() to specify a single image as a window's icon.

The following statement:

     setIconImage(image);

is equivalent to:

     ArrayList<Image> imageList = new ArrayList<Image>();
     imageList.add(image);
     setIconImages(imageList);

Note : Native windowing systems may use different images of differing dimensions to represent a window, depending on the context (e.g. window decoration, window list, taskbar, etc.). They could also use just a single image for all contexts or no image at all.

Parameters

image	the icon image to be displayed.

public synchronized 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.

On some systems only the size portion of the bounds is taken into account.

Parameters

bounds	bounds for the maximized state

public 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 `null` then any existing menu bar on this frame is removed.

public void setResizable (boolean resizable)

Sets whether this frame is resizable by the user.

Parameters

resizable	`true` if this frame is resizable; `false` otherwise.

public synchronized 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 old programs this method still accepts Frame.NORMAL and Frame.ICONIFIED but it only changes the iconic state of the frame, other aspects of frame state are not affected by this method.

Parameters

state	either `Frame.NORMAL` or `Frame.ICONIFIED`.

public void setTitle (String title)

Sets the title for this frame to the specified string.

Parameters

title	the title to be displayed in the frame's border. A `null` value is treated as an empty string, "".

public void setUndecorated (boolean undecorated)

Disables or enables decorations for this frame. This method can only be called while the frame is not displayable.

Parameters

undecorated	`true` if no frame decorations are to be enabled; `false` if frame decorations are to be enabled.

Throws

	if the frame is displayable.

Protected Methods

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.

Returns

the parameter string of this frame
