For the application we are working on we have rich text fields that can

The way to make an editable field non-editable is to click anywhere
outside of the field.
Clicking on an unselected field selects it.
The way to make a field editable is to click on the field when it is
The problem is that when a selected, but non-editable field is clicked
on the insertion point should be set based on the position of the click.
I can see two possible solutions but I don't know how to implement
either of them. For selected but non-editable fields:
1...When the field gets a click set the editable property to true and
then post the click event to the field again, or create an event to post
to the field.
2...When the field gets the click from the x,y position of the click
determine the offset into the text-string of the field and call
setSelection based on the offset into the text-string.
I see a way to possibly implement the 2nd solution, but it is a really
Does anyone have a suggestion as to how this should be done?
