Method Detail

setSelectionBackground

public void setSelectionBackground(java.awt.Color c)

setBorderColor

public void setBorderColor(java.awt.Color c)

getBorderColor

public java.awt.Color getBorderColor()

viewToModel

public int viewToModel(int x,
                       int y)

Converts the given place in the view coordinate system to the nearest representative location in the model.

setText

public void setText(java.lang.String text)

getText

public java.lang.String getText()

select

public void select(int selectionStart,
                   int selectionEnd)

Selects the text between the specified start and end positions.

This method sets the start and end positions of the selected text, enforcing the restriction that the start position must be greater than or equal to zero. The end position must be greater than or equal to the start position, and less than or equal to the length of the text component's text. The character positions are indexed starting with zero. The length of the selection is endPosition - startPosition, so the character at endPosition is not selected. If the start and end positions of the selected text are equal, all text is deselected.

If the caller supplies values that are inconsistent or out of bounds, the method enforces these constraints silently, and without failure. Specifically, if the start position or end position is greater than the length of the text, it is reset to equal the text length. If the start position is less than zero, it is reset to zero, and if the end position is less than the start position, it is reset to the start position.

Parameters:

selectionStart - the zero-based index of the first character to be selected

selectionEnd - the zero-based end position of the text to be selected; the character at selectionEnd is not selected
