Method Details

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)
            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

drawUnselectedText

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

getPreferredSpan

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

modelToView

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

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.
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
