Hello
It's been asked before on this newsgroup, but there has never been an
answer.
Is there a short tutorial, WIKI page or simple code snippet on how to
use the JFace field assist (org.eclipse.jface.fieldassist) API? I have a
dialog containing a few Text controls and would like to show the user
which fields are mandatory and where the input was not valid.
Thanks in advance for any help or pointer on that.
Christian

Hi, Christian.
I've just answered the older message, but am repeating the answer here
just in case...
There is a field assist example included in the SDK examples build. You
can download the SDK examples and install into your host Eclipse, or you
can check out the plug-in org.eclipse.ui.examples.fieldassist and run it
from within Eclipse by launching another Eclipse.
The example includes a very simple dialog, and preference pages which let
you try different configurations of content assist. After installing the
example, look for FieldAssist in the menu bar and choose "Open Field
Assist Dialog". The preference pages are "Field Assist Example
Preferences" and its sub-page, "Content Assist Preferences."
The example itself is documented in the Examples Guide (Help->Help
Contents->Platform Plug-in Developer Guide->Examples
Guide->Workbench->Field Assist Example).
Documentation for field assist itself is not yet available..I'm working on
that for RC3/RC4...

You mention showing mandatory fields, so here is some more specific info:
- the JFace field assist support allows for generic decorations around a
field, and includes a decoration registry (FieldDecorationRegistry) which
allows you to retrieve the image for a required field.
- the class FieldAssistColors lets you query the color for required fields
- the SDK itself does not yet use the decorator, and uses the color only
in places. There was much discussion about what kind of required field
emphasis should be used, and we could not come to an agreement in time for
3.2. If you are interested in the discussion and history, see
https://bugs.eclipse.org/bugs/show_bug.cgi?id=120238
