- public class PasswordView
- extends FieldView
Implements a View suitable for use in JPasswordField
UI implementations. This is basically a field ui that
renders its contents as the echo character specified
in the associated component (if it can narrow the
component to a JPasswordField).

PasswordView
public PasswordView(Element elem)
- Constructs a new view wrapped on an element.
- Parameters:
elem
- the element
drawUnselectedText
protected int drawUnselectedText(Graphics g,
int x,
int y,
int p0,
int p1)
throws BadLocationException
- Renders the given range in the model as normal unselected
text. This sets the foreground color and echos the characters
using the value returned by getEchoChar().
- Overrides:
- drawUnselectedText in class PlainView
- Parameters:
g
- the graphics contextx
- the starting X coordinate >= 0y
- the starting Y coordinate >= 0p0
- the starting offset in the model >= 0p1
- the ending offset in the model >= p0- Throws:
- BadLocationException - if p0 or p1 are out of range
drawSelectedText
protected int drawSelectedText(Graphics g,
int x,
int y,
int p0,
int p1)
throws BadLocationException
- Renders the given range in the model as selected text. This
is implemented to render the text in the color specified in
the hosting component. It assumes the highlighter will render
the selected background. Uses the result of getEchoChar() to
display the characters.
- Overrides:
- drawSelectedText in class PlainView
- Parameters:
g
- the graphics contextx
- the starting X coordinate >= 0y
- the starting Y coordinate >= 0p0
- the starting offset in the model >= 0p1
- the ending offset in the model >= p0- Throws:
- BadLocationException - if p0 or p1 are out of range
drawEchoCharacter
protected int drawEchoCharacter(Graphics g,
int x,
int y,
char c)
- Renders the echo character, or whatever graphic should be used
to display the password characters. The color in the Graphics
object is set to the appropriate foreground color for selected
or unselected text.
- Parameters:
g
- the graphics contextx
- the starting X coordinate >= 0y
- the starting Y coordinate >= 0c
- the echo character- Returns:
- the updated X position >= 0
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.
- Overrides:
- modelToView in class FieldView
- Parameters:
pos
- the position to convert >= 0a
- the allocated region to render into- Returns:
- the bounding box of the given position
- Throws:
- BadLocationException - if the given position does not
represent a valid location in the associated document
- See Also:
View.modelToView(int, java.awt.Shape, javax.swing.text.Position.Bias)
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 class FieldView
- Parameters:
fx
- the X coordinate >= 0.0ffy
- the Y coordinate >= 0.0fa
- the allocated region to render into- Returns:
- the location within the model that best represents the
given point in the view
