If I could simply getCursorPos() in my RichTextArea according to the text displayed (getText()), then I could use space boundaries between words to discover the word that is being changed, and use simple String replace methods to affect the HTML. But I really don't mind knowing a position according to the HTML either! Pardon my ignorance, but do you actually have the methods for me to do this with my RichTextArea?
But for me this is really all about the fact that any editing of the text by the user (e.g. adding/deleting a character) happens AFTER the keypress/keydown events are fired, so I cannot know WHAT the resulting String will be!! This is crazy, and that's what necessitates me to know the cursorPos, so that I can add the character being added/ deleted (which is told to me by the keypress event) in its PROSPECTIVE position (which, again, I have no way of knowing!!). So, for the time being, how do I do a time delayed function in GWT i.e. what's the equivalent of JavaScript's "setInterval" in GWT? So that I can grab the new and old Strings and compare them to know at which cursor position I am.
