Examples of javax.swing.text.View.modelToView()

javax.swing.text.View.modelToView()
Provides a mapping, for a given character, from the document model coordinate space to the view coordinate space. @param pos the position of the desired character (>=0) @param a the area of the view, which encompasses the requested character @param b the bias toward the previous character or thenext character represented by the offset, in case the position is a boundary of two views; b will have one of these values:
- Position.Bias.Forward
- Position.Bias.Backward
@return the bounding box, in view coordinate space,of the character at the specified position @exception BadLocationException if the specified position doesnot represent a valid location in the associated document @exception IllegalArgumentException if b is not one of thelegal Position.Bias values listed above @see View#viewToModel
