Constructor Detail

JDotMatrixDisplay

public JDotMatrixDisplay(int columns,
                         int rows)
                  throws java.lang.IllegalArgumentException

Create a new dot matrix display.

Parameters:

columns - Number of columns, or characters, per row.

rows - Number of rows.

Throws:

java.lang.IllegalArgumentException - Invalid columns or rows specified.

Method Detail

getColumns

public int getColumns()

Get the number of columns, characters, in the display.

Returns:

The number of columns.

getRows

public int getRows()

Get the number of rows in the display.

Returns:

The number of rows.

setUI

public void setUI(DotMatrixDisplayUI ui)

Sets the new UI delegate.

Parameters:

ui - New UI delegate.

updateUI

public void updateUI()

Resets the UI property to a value from the current look and feel.

Overrides:

updateUI in class javax.swing.JComponent

See Also:

JComponent.updateUI()

getUI

public DotMatrixDisplayUI getUI()

Returns the UI object which implements the L&F for this component.

Returns:

UI object which implements the L&F for this component.

See Also:

setUI(com.jpeterson.virtlcd.swing.ui.DotMatrixDisplayUI)

getUIClassID

public java.lang.String getUIClassID()

Returns the name of the UI class that implements the L&F for this component.

Overrides:

getUIClassID in class javax.swing.JComponent

Returns:

The name of the UI class that implements the L&F for this component.

getModel

public DotMatrixDisplayModel getModel()

getText

public java.lang.String getText()

Get the text displayed.

Returns:

The text displayed.

setText

public void setText(java.lang.String text)

Set the text to display.

Parameters:

text - The text displayed. Multiple line displays will most likely break the string by a new line. Lines that are too long will most likely be truncated. The actual display is controlled by the UI component.
