                                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

protected int drawSelectedText(Graphics g,
                               int x,
                               int y,

                               int p1)
            throws BadLocationException

Draws selected text at a given position.

Overrides:

drawSelectedText in interface PlainView

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

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

Draws unselected text at a given position.

Overrides:

drawUnselectedText in interface PlainView

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

public float getPreferredSpan(int axis)

Determines the preferred span for this view along an axis.

Overrides:

getPreferredSpan in interface FieldView

Parameters:

axis - to get the preferred span of

Returns:

the preferred span of the axis

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

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.

Overrides:

modelToView in interface FieldView

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

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.

Overrides:

viewToModel in interface FieldView

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
