Example 46 with StyledDocument

use of javax.swing.text.StyledDocument in project chatty by chatty.

the class LinkController method getElement.

public static Element getElement(MouseEvent e) {
    JTextPane text = (JTextPane) e.getSource();
    Point mouseLocation = new Point(e.getX(), e.getY());
    int pos = text.viewToModel(mouseLocation);
    if (pos >= 0) {
        /**
         * Check if the found element is actually located where the mouse is
         * pointing, and if not try the previous element.
         *
         * This is a fix to make detection of emotes more reliable. The
         * viewToModel() method apparently searches for the closest element
         * to the given position, disregarding the size of the elements,
         * which means on the right side of an emote the next (non-emote)
         * element is nearer.
         *
