Interface ITextLocator

All Superinterfaces:

IEMFigure, org.eclipse.draw2d.IFigure

public interface ITextLocator
extends IEMFigure

Locates text into (segment of) one text line. Supposed to implement by classes drawing text in segment of line. Characters of text are indexed. First character have index 0.

Method Detail

getStart

org.eclipse.draw2d.geometry.Point getStart(int charIndex)

Returns top left point of rectangle bounding character with index charIndex.

Parameters:

charIndex -

Returns:

most left most top point in smallest rectangle completely surrounding chracter with index charIndex.

getEnd

org.eclipse.draw2d.geometry.Point getEnd(int charIndex)

Returns top right point of rectangle bounding character with index charIndex.

Parameters:

charIndex - index of character end retreival

Returns:

most right most top point in smallest rectangle completely surrounding chracter with index charIndex.

getCharIndexAtPos

int getCharIndexAtPos(org.eclipse.draw2d.geometry.Point loc)

Returns character's index at location loc.

Parameters:

loc - 2d point

Returns:

character index from start of line at point loc

getTextBounds

org.eclipse.draw2d.geometry.Rectangle getTextBounds()

Bounds of whole text. Smallest rectangle completely surrounding located text.

Returns:

rectangle completely surrounding diplayed text.

getTextBounds

org.eclipse.draw2d.geometry.Rectangle getTextBounds(int start,
                                                    int end)

Bounds of substring of text. Substring consist of characters with indices greater or equal than start and less or equal end. Smallest rectangle completely surrounding substring.

Parameters:

start - of substring

end - of substring

Returns:

rectangle completely surrounding substring.

getText

String getText()

Returns:

Returns text located by this ITextLocator.

updateText

void updateText(String text)

Stores the new Text

Parameters:

text - newText
