Inserting images to mark text boundaries

Question

Ive added text to a JTextPane from a file.
and by mouse click ive inserted character
to mark the boundaries of the text.
instead of character ive to do with images
for marking the segment boundaries.
please suggest me some method for inserting
images in TextPane for marking boundaries

Answer 1

Sorry Andre..Still im not getting what you are saying.. im trying to do like this..Could u pls suggest me where i went wrong..Im inserting the icon directly to textpane..rather than to label nd inserting label to textpane bcos label with image cant be retained when mouse is clicked over several times in textpane....
