Method Detail

drawEchoCharacter

protected int drawEchoCharacter(Graphics g, int x, int y, char ch)

Draws one echo character at a given position.

Parameters: g the Graphics object to draw to x the x-position y the y-position ch the echo character

Returns: the next x position right of the drawn character

drawSelectedText

protected int drawSelectedText(Graphics g, int x, int y, int p0, int p1)

Draws selected text at a given position.

Parameters: g the Graphics object to draw to x the x-position y the y-position p0 the position of the first character to draw p1 the position of the first character not to draw

Returns: the next x position right of the drawn character

drawUnselectedText

protected int drawUnselectedText(Graphics g, int x, int y, int p0, int p1)

Draws unselected text at a given position.

Parameters: g the Graphics object to draw to x the x-position of the start of the baseline y the y-position of the start of the baseline p0 the position of the first character to draw p1 the position of the first character not to draw

Returns: the next x position right of the drawn character

getPreferredSpan

public float getPreferredSpan(int axis)

Determines the preferred span for this view along an axis.

Parameters: axis to get the preferred span of

Returns: the preferred span of the axis

modelToView

public Shape modelToView(int pos, Shape a, Position.Bias b)

Provides a mapping from the document model coordinate space to the coordinate space of the view mapped to it. This method is overridden to provide a correct mapping with respect to the echo char and not to the real content.

Parameters: pos - the position to convert >= 0 a - the allocated region to render into b - typesafe enumeration to indicate bias to a position in the model.

Returns: the bounding box of the given position

Throws: BadLocationException if the given position does not represent a valid location in the associated document

viewToModel

public int viewToModel(float fx, float fy, Shape a, Position.Bias[] bias)

Provides a mapping from the view coordinate space to the logical coordinate space of the model.

Parameters: fx - the X coordinate >= 0.0f fy - the Y coordinate >= 0.0f a - the allocated region to render into bias - typesafe enumeration to indicate bias to a position in the model.

Returns: the location within the model that best represents the given point in the view
