org.trianacode.gui.Display

public class Display
extends java.lang.Object

This class provides methods for calculating the size of the screen which Triana is currently running on. Based on the size OldUnit Programmers can compensate when creating OldUnit Windows so that they appear relavive to the size of the screen and not way out of proportion. The ratio's are calculated relative to a machine running a 1024 x 768 computer. If the machine has a better resolution than this then Triana will appear larger so that it occupies the same proportion than it does on an SVGA screen.

Triana uses this class extensively when creating its graphical user interface.

This class also provides some sueful routines which Triana uses. For example there is a function here which displays Triana's title screen.

Methods

Modifier and Type	Method and Description
static void	centralise(java.awt.Window fr) Puts the window in the middle of the screen.
static void	clipFrameToScreen(java.awt.Component fr)
static java.awt.Point	clipFrameToScreen(java.awt.Component fr, int x, int y) Makes sure that the specified JFrame doesn't dissappear off the screen by checking the x and y coordinates of its desired position and clipping them so that it fits onto the particular screen.

static javax.swing.JPanel	getTrianaLogo()
static javax.swing.JWindow	showTitleScreen()
static int	x(int size) This routine calibrates the X size or coordinate sent to it, so that things look the same no matter what computer you are on i.e.

Constructor Detail

Display

public Display()

Method Detail

x

public static int x(int size)

This routine calibrates the X size or coordinate sent to it, so that things look the same no matter what computer you are on i.e. it scales the application to the size of this computer's screen.

y

public static int y(int size)

This routine calibrates the Y size or coordinate sent to it, so that things look the same no matter what computer you are on i.e. it scales the application to the size of this computer's screen.

clipFrameToScreen

public static java.awt.Point clipFrameToScreen(java.awt.Component fr,
                               int x,
                               int y)

Makes sure that the specified JFrame doesn't dissappear off the screen by checking the x and y coordinates of its desired position and clipping them so that it fits onto the particular screen.

Parameters:

fr - the frame to be clipped into the screen size

x - the desired x coordinate

y - the desired y coordinate

clipFrameToScreen

public static void clipFrameToScreen(java.awt.Component fr)

clipFrameToScreen

public static java.awt.Point clipFrameToScreen(java.awt.Window fr,
                               java.awt.Point p)

Makes sure that the specified JFrame doesn't dissappear off the screen by checking the x and y coordinates of its desired position and clipping them so that it fits onto the particular screen. OldUnit Programmers should use this function to place their displaying windows on the screen. Subclasses of ParameterPanel don't need to call this as it is called automatically.

Parameters:

fr - the frame to be clipped into the screen size

clipFrameToScreen

public static java.awt.Point clipFrameToScreen(java.awt.Component fr,
                               java.awt.Point p)

clipFrameToScreen

public static java.awt.Point clipFrameToScreen(java.awt.Window fr,
                               int x,
                               int y)

centralise

public static void centralise(java.awt.Window fr)

Puts the window in the middle of the screen.

Parameters:

fr - the frame to be placed in the middle of the screen

getAnchorPoint

public static java.awt.Point getAnchorPoint(java.lang.Object anchor,
                            java.awt.Component comp)

Returns:

an anchor point for the specified object. If the object is a menu in a pop-up window then this is based on the invoker, if the object is not a component/invalid then comp is centralised.

showTitleScreen

public static javax.swing.JWindow showTitleScreen()

getTrianaLogo

public static javax.swing.JPanel getTrianaLogo()
