Constructor Detail

LCDMeter

public LCDMeter(int x,
                int y,
                int width,
                int height,
                int digits)

Creates a new LCDMeter.

NOTE: The size of the seven-segment digits will depent on the number of desired digits and the size of the bounding box.

Parameters:

x - the x coordinate for the upper left of the bounding box.

y - the y coordinate for the upper left of the bounding box.

width - the width of the bounding box.

height - the height of the bounding box.

digits - the number of digits.

LCDMeter

public LCDMeter(int x,
                int y,
                int width,
                int height,
                int digits,
                boolean border)

Constructs a bordered LCDMeter.

Parameters:

x - the x coordinate for the upper left of the bounding box.

y - the y coordinate for the upper left of the bounding box.

width - the width of the bounding box.

height - the height of the bounding box.

digits - the number of digits.

border - if true a border is painted around the LCDMeter (default is off).

Method Detail

paint

public void paint()

Repaints the LCDMeter.

Overrides:

paint in class Component

setBounds

public void setBounds(int x,
                      int y,
                      int width,
                      int height)

Sets a new position and size for the LCDMeter. The component is repainted.

Overrides:

setBounds in class Component

Parameters:

x - the new x coordinate

y - the new y coordinate

width - the new width

height - the new height

setGraphics

public void setGraphics(jcontrol.io.Graphics g)

This method is called to set the main Display context for this component. * Normally, this is done only for the top-level container, then, all child components are set automatically.

Overrides:

setGraphics in class Component

Parameters:

g - the Display

setLocation

public void setLocation(int x,
                        int y)

Moves this LCDMeter to a new location.

Overrides:

setLocation in class Component

Parameters:

x - the x-coordinate of the new location's top-left corner.

y - the y-coordinate of the new location's top-left corner.

setValue

public void setValue(int value)

Sets the value to display on the LCDMeter.

Parameters:

value - the value to show.

transferFocus

public boolean transferFocus()

LCDMeter never gains the input focus.

Overrides:

transferFocus in class Component

Returns:

true, if the focus was transferred successfully.
