I sent a version of the note below to the GWT Rich-Text Editor group.
But then I noticed that there are a number of discussions of RichText
in this much larger group. I need all the help I can get ;-)
I would like some guidance on how to go about designing an app that
would do things such as the following:
The server downloads text, as an array (Collection) of tokens
(Strings), which would be displayed in the text area.
Other arrays of information would be downloaded that could be used to
decorate the text.
For example, say we downloaded information about which of the tokens
or token groups are the names of companies.
The user would have a menu that includes the item Companies.
When that menu item is selected, the text for the companies would be
highlighted in red.
My initial response was Don't use a RichTextArea (RTA) for this. After
re-reading the post, I think what you want to accomplish is outside the
scope of the GWT RTA widget.
Have you looked at TinyMCE? http://en.wikipedia.org/wiki/Tinymce
It's probably going to give you more horsepower than the GWT RTA.
The basic question for this type of app is: How do I access particular
Strings and alter their styling?
Is DOM the way to go?
In the dual problem, how would I discover a String that the user has
selected and designated as a company - one that was not on the
original list?
The String chosen would be returned to the server to update its list
of company names.
This type of application is typical of many apps that would be of
great benefit to researchers in natural language processing.
There are about 600 members of the mailing list at my site,
bionlp.org, many of who would be interested in such apps.
Any and all suggestions, leads, etc., most welcome.
