modelToView

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

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)

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.

damageRange

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

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)

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)

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
