Changing contents of an editor [message #326186]

Hi there.

I've built an editor which displays a set of SWT based editors like
org.eclipse.swt.widgets.Text.
The input file for this editor consists of different parts: a root part
and a set of other parts. The editor shall display only one part in a
time. On opening the editor will show the root part. To switch the part
to be displayed I built a tree viewer in the outline view. By selecting
an item in the outline the content of the editor shall change and so the
selected part from input file shall be displayed.
My problem is, that I have absolutely no idea how to tell the editor to
update and redraw itself. Does anyone have a hint?

Thanks in advance,
Jan

There are several options, depending on the user experience you want to
provide. Instead of using the outline view you could use a multi-page
(multi-tab) editor, one tab for each part. Another idea would be to have
a single tab editor but follow the master/details UI design (like the
Extensions tab of the plugin editor).
Finally, if you really want to keep using the Outline view, you could
use a StackLayout in your editor to show only one composite at a time
(each composite representing a part of your file).

Hope this helps,
Eric

Thanks a lot for these helpful hints. The StackLayout is exactly what I
wanted but did not know that it exists.
