Method Detail

getCenterPoint

public static java.awt.Point getCenterPoint()

Computes the center point of the current screen device. If this method is called on JDK 1.4, Xinerama-aware results are returned. (See Sun-Bug-ID 4463949 for details).

Returns:

the center point of the current screen.

getMaximumWindowBounds

public static java.awt.Rectangle getMaximumWindowBounds()

Computes the maximum bounds of the current screen device. If this method is called on JDK 1.4, Xinerama-aware results are returned. (See Sun-Bug-ID 4463949 for details).

Returns:

the maximum bounds of the current screen.

centerFrameOnScreen

public static void centerFrameOnScreen(java.awt.Window frame)

Positions the specified frame in the middle of the screen.

Parameters:

frame - the frame to be centered on the screen.

positionFrameOnScreen

public static void positionFrameOnScreen(java.awt.Window frame,
                                         double horizontalPercent,
                                         double verticalPercent)

Positions the specified frame at a relative position in the screen, where 50% is considered to be the center of the screen.

Parameters:

frame - the frame.

horizontalPercent - the relative horizontal position of the frame (0.0 to 1.0, where 0.5 is the center of the screen).

verticalPercent - the relative vertical position of the frame (0.0 to 1.0, where 0.5 is the center of the screen).

positionFrameRandomly

public static void positionFrameRandomly(java.awt.Window frame)

Positions the specified frame at a random location on the screen while ensuring that the entire frame is visible (provided that the frame is smaller than the screen).

Parameters:

frame - the frame.
