java - Design Suggestion for Rich Client UIs -

background:

i have extensive experience in web applications, have little or no experience rcp. presently, working java swing api. good. problem is, don't feel confident design.

question:

in web application when implement mvc, forward request view. controller doesn't care show it. going displayed on page, typically. in rcp, need know show form/table/etc.. mean panel, right or left, or down. requires reference container component in desire show thing. how should design our code reference?

take:

i keeping reference first level components in main class -- has main() method. , wherever need component, doing like,

jpanel formpanel = mainapp.getmainpanel().getformpanel(); .. jpanel treepanel = mainapp.getmainpanel().gettreepanel(); 

is okay?

mvc isn't of thing in rcp, people talk largely it's bullshit.

for sure having model of business objects that's separate , had no dependency on ui code important. lines between views , controllers tend more blurred wouldn't sweat much.

user interface elements naturally tend organized in tree have, though global variables such main panel should avoided.

lean heavily on observer pattern.
