javax.swing.text.PasswordView
| PasswordView | | public class PasswordView extends FieldView (Code) | | 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).

| Field Summary | |
| static char[] | ONE
|
| Constructor Summary | |
| public | PasswordView(Element elem)
Constructs a new view wrapped on an element. |
| Method Summary | |
| 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. | | protected int | drawSelectedText(Graphics g, int x, int y, int p0, int p1)
Renders the given range in the model as selected text. | | protected int | drawUnselectedText(Graphics g, int x, int y, int p0, int p1)
Renders the given range in the model as normal unselected
text. | | public float | getPreferredSpan(int axis)
Determines the preferred span for this view along an
axis.
Parameters:
axis - may be either View.X_AXIS or View.Y_AXIS the span the view would like to be rendered into >= 0.Typically the view is told to render into the spanthat is returned, although there is no guarantee. | | 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. | | 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. |
| PasswordView | | public PasswordView(Element elem)(Code) | | Constructs a new view wrapped on an element.
Parameters:
elem - the element |
| drawEchoCharacter | | protected int drawEchoCharacter(Graphics g, int x, int y, char c)(Code) | | 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
Parameters:
x - the starting X coordinate >= 0
Parameters:
y - the starting Y coordinate >= 0
Parameters:
c - the echo character the updated X position >= 0 |
| drawSelectedText | | protected int drawSelectedText(Graphics g, int x, int y, int p0, int p1) throws BadLocationException(Code) | | 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.
Parameters:
g - the graphics context
Parameters:
x - the starting X coordinate >= 0
Parameters:
y - the starting Y coordinate >= 0
Parameters:
p0 - the starting offset in the model >= 0
Parameters:
p1 - the ending offset in the model >= p0 the X location of the end of the range >= 0
exception:
BadLocationException - if p0 or p1 are out of range |
| drawUnselectedText | | protected int drawUnselectedText(Graphics g, int x, int y, int p0, int p1) throws BadLocationException(Code) | | 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().
Parameters:
g - the graphics context
Parameters:
x - the starting X coordinate >= 0
Parameters:
y - the starting Y coordinate >= 0
Parameters:
p0 - the starting offset in the model >= 0
Parameters:
p1 - the ending offset in the model >= p0 the X location of the end of the range >= 0
exception:
BadLocationException - if p0 or p1 are out of range |
| getPreferredSpan | | public float getPreferredSpan(int axis)(Code) | | Determines the preferred span for this view along an
axis.
Parameters:
axis - may be either View.X_AXIS or View.Y_AXIS the span the view would like to be rendered into >= 0.Typically the view is told to render into the spanthat is returned, although there is no guarantee. The parent may choose to resize or break the view. |
| modelToView | | public Shape modelToView(int pos, Shape a, Position.Bias b) throws BadLocationException(Code) | | Provides a mapping from the document model coordinate space
to the coordinate space of the view mapped to it.
Parameters:
pos - the position to convert >= 0
Parameters:
a - the allocated region to render into the bounding box of the given position
exception:
BadLocationException - if the given position does notrepresent a valid location in the associated document

| viewToModel | | public int viewToModel(float fx, float fy, Shape a, Position.Bias[] bias)(Code) | | Provides a mapping from the view coordinate space to the logical
coordinate space of the model.
Parameters:
fx - the X coordinate >= 0.0f
Parameters:
fy - the Y coordinate >= 0.0f
Parameters:
a - the allocated region to render into the location within the model that best represents thegiven point in the view
