Methods Summary
public int	getNextVisualPositionFrom(javax.swing.text.JTextComponent text, int pos, javax.swing.text.Position$Bias bias, int direction, javax.swing.text.Position$Bias[] biasRet) Returns the next visual position to place the caret at from an existing position. The default implementation simply forwards the method to the root View. Subclasses may wish to further restrict the location based on additional criteria. param text JTextComponent containing text param pos Position used in determining next position param bias Bias used in determining next position param direction the direction from the current position that can be thought of as the arrow keys typically found on a keyboard. This will be one of the following values: SwingConstants.WEST SwingConstants.EAST SwingConstants.NORTH SwingConstants.SOUTH param biasRet Used to return resulting Bias of next position return the location within the model that best represents the next location visual position exception BadLocationException exception IllegalArgumentException if direction doesn't have one of the legal values above return text.getUI().getNextVisualPositionFrom(text, pos, bias, direction, biasRet);
public void	moveDot(javax.swing.text.NavigationFilter$FilterBypass fb, int dot, javax.swing.text.Position$Bias bias) Invoked prior to the Caret moving the dot. The default implementation calls directly into the FilterBypass with the passed in arguments. Subclasses may wish to conditionally call super with a different location, or invoke the necessary methods on the FilterBypass. param fb FilterBypass that can be used to mutate caret position param dot the position >= 0 param bias Bias for new location fb.moveDot(dot, bias);
public void	setDot(javax.swing.text.NavigationFilter$FilterBypass fb, int dot, javax.swing.text.Position$Bias bias) Invoked prior to the Caret setting the dot. The default implementation calls directly into the FilterBypass with the passed in arguments. Subclasses may wish to conditionally call super with a different location, or invoke the necessary method on the FilterBypass param fb FilterBypass that can be used to mutate caret position param dot the position >= 0 param bias Bias to place the dot at fb.setDot(dot, bias);
