Hi!

I just read in the wiki:
"RWT reuses the original SWT layout manager implementations and therefore
layouting takes place on the server-side. "

Up to now I thought, RAP reuses the Qooxdoo Layout-Mechanism. But now IŽm
not so sure anymore, how can this sentence be understood? Thanks in
advance!

Hi Martin,

The sentence is to understand as it's described there ;)
RAP uses the layout managers of SWT to calculate the positions and sizes
of the widgets on the server-side. Only the real bounds were send to the
client where the qooxdoo widgets are rendered in the end (based on the
informations computed on the server). The layout managers of qooxdoo
itself are mostly eliminated in the build except some simple ones which
we are using inside some widgets.

Hi Benny,

thanks;),
ok, I could not imagine how the mapping between the SWT LayoutManagers are
mapped to Qooxdoo-Layouting on the Clientside, but now this makes sense as
I looked little more at the Code.

Hi all!

I have the bad luck that I must introduce RAP Technology to our Java
Developers, now I must work throuh the deep functionality.
I just realized, that it is possible to create Custom Components without
programming a JS-Client widget at all using the standard layouts in RWT
and standard buttons etc.. (I realized that when I saw the Calendar Widget
Source Code from Frank Appel in the "Looking like a Website" - Thread)
BUT,
I also realized that for example the Qooxdoo-GridLayout is not shipped
within the qooxdoo implementation you use for RAP, so how do you render a
SWT GridLayout in Qooxdoo??

Thank you very much, working through this technology is quite a mess,
since I am also not as experienced as my boss thinks I sgould be;)

That's an easy one: the layouts are rendered on the server. In fact we
use the same code as SWT does - the layout managers. Only position and
size (the bounds) are sended to the client. For example a resize of a
shell will do a turnaround, the layout will be calculated on the server
and the new positions and sizes are sended to the client for each widget.

Hope that helps!
