Hi All,

Is there a Controller to keep both the Texts and Images,

If we use GC drawImage and drawText

How can we retreive the values back from the Display

Thanks

You can't get values back from the display because the display is just a
bitmap of pixels. The draw image and draw text simply convert down to
setting pixels in the display. The original image and text are not
retained by the display.

What is it you are really trying to do? Are you trying to just capture
the picture of what is on the display? Are you trying to keep a record
of what images and text were drawn?

Thanks for the reply Rich,

What am going to do is, develop a very primitive word processor using SWT.

For e.g users can inserts(input) texts and images(to a certain position)
and should be able to save and reload with the same settings (positions).
basically a primitive word processor.

Eventually to generate a XML from the display.

It would be really handy if I can incooperate drag and drop and cut and
paste features into this, I know there allready developed little word
processors which supports Texts only but not the both Texts and Images at
the same time.

Can u let us know how to proceed on this, Ideas are welcome.

wating for a reply soon

thanks

Is FormText Control suitable for this

It's unlikely that you'll find an SWT control that'll support this sort
of manipulation directly. What you'll need to do is use or create a
higher level editor, most likely using GEF. The WYSIWYG HTML editor
included in Rational Application Developer is the closest thing I know
of to your use case, and that's implemented using GEF.

Hope this helps,
