Hello.

Is there a text figure that supports something like getLocationAtOffset?
I provide the character offset as parameter and want the x and y coordinates.
Or any other solutions to get a specific text position inside a figure that supports text?

Regards,
Kai

A solution could be TextFlow.getCarePlacement if I understand the API documentation correctly.
What I want to do is to mark up specific strings inside a text, like StyledText with it StyleRange's
does. Is this possible with Draw2D?
Are there any examples how to use the stuff in org.eclipse.draw2d.text?

Regards,
Kai

No, getCaretPlacement did not help. Any other way to get the positions coordinates of an offset
inside a TextFlow?

Ok, I solved that problem by adding a layout listener to the TextFlow. After the TextFlow was layout
(method postLayout) I can use the getCaretPlacement method and get the correct offset locations (but
strangely only when the text ends with \n).
