[Yahor Radtsevich (JIRA)]

Yahor Radtsevich commented on JBIDE-6229:
-----------------------------------------

To implements this, a method to locate the selected text on the screen is necessary. Currently I have two different approaches, but none of them is working good enough:
1.- Insert invisible DIVs before and after the selected text
   - Get screen position of the DIVs
   - Delete the DIVs from the DOM tree
 Weak points:
   - this approach modifies DOM tree
   - selection disappears in the case if a DIV is inserted before the selected text node (before symbol with index 0).
2.- Clone the selected text node
   - Replace the original node by the clone
   - Insert invisible DIVs and get their position as in the 1st approach.
   - Replace the clone with the original back
This approach does not modify DOM tree, but I faced a XULRunner bug when selection disappears from the screen.
