 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).- See Also:

Method Detail- 
drawUnselectedText@Deprecated(since="9") protected int drawUnselectedText(Graphics g, int x, int y, int p0, int p1) throws BadLocationException Deprecated.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:
- drawUnselectedTextin class- PlainView
- Parameters:
- g- the graphics context
- x- the starting X coordinate >= 0
- y- the starting Y coordinate >= 0
- p0- the starting offset in the model >= 0
- p1- the ending offset in the model >= p0
- Returns:
- the X location of the end of the range >= 0
- Throws:
- BadLocationException- if p0 or p1 are out of range
 
 - 
drawSelectedText@Deprecated(since="9") protected int drawSelectedText(Graphics g, int x, int y, int p0, int p1) throws BadLocationException Deprecated.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:
- drawSelectedTextin class- PlainView
- Parameters:
- g- the graphics context
- x- the starting X coordinate >= 0
- y- the starting Y coordinate >= 0
- p0- the starting offset in the model >= 0
- p1- the ending offset in the model >= p0
- Returns:
- the X location of the end of the range >= 0
- Throws:
- BadLocationException- if p0 or p1 are out of range
 
 - 
drawEchoCharacter@Deprecated(since="9") protected int drawEchoCharacter(Graphics g, int x, int y, char c) Deprecated.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 context
- x- the starting X coordinate >= 0
- y- the starting Y coordinate >= 0
- c- the echo character
- Returns:
- the updated X position >= 0
 
 - 
drawEchoCharacterprotected float drawEchoCharacter(Graphics2D g, float x, float 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 context
- x- the starting X coordinate- >= 0
- y- the starting Y coordinate- >= 0
- c- the echo character
- Returns:
- the updated X position >= 0
- Since:
- 9
 
 - 
modelToViewpublic 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:
- modelToViewin class- FieldView
- Parameters:
- pos- the position to convert >= 0
- a- the allocated region to render into
- b- the bias toward the previous character or the next character represented by the offset, in case the position is a boundary of two views;- bwill have one of these values:-  Position.Bias.Forward
-  Position.Bias.Backward
 
-  
- 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)
 
 - 
viewToModelpublic 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:
- viewToModelin class- FieldView
- Parameters:
- fx- the X coordinate >= 0.0f
- fy- the Y coordinate >= 0.0f
- a- the allocated region to render into
- bias- the returned bias
- Returns:
- the location within the model that best represents the given point in the view
- See Also:
- View.viewToModel(float, float, java.awt.Shape, javax.swing.text.Position.Bias[])
 
 - 
getPreferredSpanpublic float getPreferredSpan(int axis) Determines the preferred span for this view along an axis.- Overrides:
- getPreferredSpanin class- FieldView
- Parameters:
- axis- may be either View.X_AXIS or View.Y_AXIS
- Returns:
- the span the view would like to be rendered into >= 0. Typically the view is told to render into the span that is returned, although there is no guarantee. The parent may choose to resize or break the view.

- View.getPreferredSpan(int)
