Hello all.....I'm posting this question once again as there is no response so
far....where do I find the logic of portlets addition in Jetspeed. Since I want
to slightly change the behavior of portlets getting added from right to left
when added thro portlet selector.
Pls reply ASAP.....
Well, that's a tricky one.
A new portlet fragment is currently simply "added" to the list of (child)
fragments of the target fragment with no location information.
Note: the implementation of this has changed a lot since 2.0 to properly
support nested fragments (which really didn't work well in 2.0), but the logic
remained the same.
Check the LayoutPortlet.addPortletToPage() method(s).
Now, this doesn't help you much yet as what you see happen (new portlets always
shown to the right) is determined by the ColumnLayout implementation
(also part of the jetspeed-layout source tree) when rendering a page.
So, if you want to change this I think you have two options:
- Modify the portlet selector and the (Multi)LayoutPortlet to provide location
information when adding one or more portlets.
This means you will need to investigate the content and structure of the
current (target) fragment to determine what the proper location of a new
portlet should be (e.g. row/column position).
Note: the portlet selector allows you to add multiple portlets at the same
time which might complicate things a lot!!!
- Modify the ColumnLayout logic how it determines the position of portlets
without location specification and probably persist that as well after
doing so.
Beware: the ColumnLayout implementation is *very* tricky code.
If you manage to create a proper (generic) implementation for this it would be
great if you could contribute it back!
But noted again: the 2.1-dev implementation for this has been changed major, so
I suggest you start with the current trunk source otherwise you're gonna need to
redo it after we release 2.1 (soon I hope).
Happy coding,
Ate

Thanks for the response. I want to use two column but when I add a portlet I
want to have some location order...ie it should get added to left...now it is
adding to the right side of the window. :-)

That is due to the fact that you problaly have the Layout set to "Two
Columns Layout Using Velocity", you have to set to "One Column....". Hope it
helped you

Hi all... I'm using Jetspeed 2.0 multi-Db version. Whenever I add portlet it
is adding the portlet to right in the screen ...is this a default
behavior....is it possible that whenever I add a portlet it should add the
portlet to the left (When the page is blank)....I want to follow location
order...if some portlets in left ...I want to add in right else in left..
Hope I'm clear ...please respond with your comments as soon as possible
