Method Detail

modelToView

public abstract Rectangle modelToView(JTextComponent t,
                                      int pos)
                               throws BadLocationException

Class is disabled.

Converts the given location in the model to a place in the view coordinate system.

Parameters:

pos - the local location in the model to translate >= 0

Returns:

the coordinates as a rectangle

Throws:

BadLocationException - if the given position does not represent a valid location in the associated document

modelToView

public abstract Rectangle modelToView(JTextComponent t,
                                      int pos,
                                      Position.Bias bias)
                               throws BadLocationException

Class is disabled.

Converts the given location in the model to a place in the view coordinate system.

Parameters:

pos - the local location in the model to translate >= 0

Returns:

the coordinates as a rectangle

Throws:

BadLocationException - if the given position does not represent a valid location in the associated document

viewToModel

public abstract int viewToModel(JTextComponent t,
                                Point pt)

Class is disabled.

Converts the given place in the view coordinate system to the nearest representative location in the model.

Parameters:

pt - the location in the view to translate. This should be in the same coordinate system as the mouse events.

Returns:

the offset from the start of the document >= 0

viewToModel

public abstract int viewToModel(JTextComponent t,
                                Point pt,
                                Position.Bias[] biasReturn)

Class is disabled.

Provides a mapping from the view coordinate space to the logical coordinate space of the model.

Parameters:

pt - the location in the view to translate. This should be in the same coordinate system as the mouse events.

biasReturn - filled in by this method to indicate whether the point given is closer to the previous or the next character in the model

Returns:

the location within the model that best represents the given point in the view >= 0

getNextVisualPositionFrom

public abstract int getNextVisualPositionFrom(JTextComponent t,
                                              int pos,
                                              Position.Bias b,
                                              int direction,
                                              Position.Bias[] biasRet)
                                       throws BadLocationException

Class is disabled.

Provides a way to determine the next visually represented model location that one might place a caret. Some views may not be visible, they might not be in the same order found in the model, or they just might not allow access to some of the locations in the model.

Parameters:

t - the text component for which this UI is installed

pos - the position to convert >= 0

b - the bias for the position

direction - the direction from the current position that can be thought of as the arrow keys typically found on a keyboard. This may be SwingConstants.WEST, SwingConstants.EAST, SwingConstants.NORTH, or SwingConstants.SOUTH

biasRet - an array to contain the bias for the returned position

Returns:

the location within the model that best represents the next location visual position

Throws:

BadLocationException

IllegalArgumentException - for an invalid direction

damageRange

public abstract void damageRange(JTextComponent t,
                                 int p0,
                                 int p1)

Class is disabled.

Causes the portion of the view responsible for the given part of the model to be repainted.

Parameters:

p0 - the beginning of the range >= 0

p1 - the end of the range >= p0

damageRange

public abstract void damageRange(JTextComponent t,
                                 int p0,
                                 int p1,
                                 Position.Bias firstBias,
                                 Position.Bias secondBias)

Class is disabled.

Causes the portion of the view responsible for the given part of the model to be repainted.

Parameters:

p0 - the beginning of the range >= 0

p1 - the end of the range >= p0

getEditorKit

public abstract EditorKit getEditorKit(JTextComponent t)

Class is disabled.

Fetches the binding of services that set a policy for the type of document being edited. This contains things like the commands available, stream readers and writers, etc.

Returns:

the editor kit binding

getRootView

public abstract View getRootView(JTextComponent t)

Class is disabled.

Fetches a View with the allocation of the associated text component (i.e. the root of the hierarchy) that can be traversed to determine how the model is being represented spatially.

Returns:

the view

getToolTipText

public String getToolTipText(JTextComponent t,
                             Point pt)

Class is disabled.

Returns the string to be used as the tooltip at the passed in location.

Since:

1.4
