Perspective with tabs [message #540598]

Hi,

I'm trying to create an Eclipse RCP app with the following UI structure/layout:

Perspective A >>
View A (tabs container) >>
Instances of View B (multiple tabs which are separate instances of the same View class) >>
views/layout within the tab View B

(where the '>>' indicates that I want a hierarchical/containment relationship).

The idea is that a separate tab should be opened for each file being worked on, and each tab is an instance of the same View class but has it's own internal configuration and state.

I may also add a file explorer to the perspective, outside of the tabs container, in the future. But for now I need the perspective to just contain one view.

Any recommendations on how best to go about doing this?

Ideally I would like to do this declaratively as much as possible. I know you can declaratively set up the layout in a perspective, but can you do that in views too? To elaborate on this, it seems at the moment that I can use a perspectiveExtension to add View A to Perspective A, but then I am left to programmatically build the rest. Is this true?

Thanks in advance for any help.

Jits

Hi Jits,

Why do you want to contain view B in View A. As you can see, views already
have tabs so you just want a bunch of view B's. If you do the action on the
File, just open a new instance of View B. The tab you get for free

Hi Wim,

Thanks for the response.

I have a better handle on the UI concepts of the Eclipse RCP platform and so we have changed our design to fit in better (i.e.: to do what you suggest)

For posterity, let me explain what we had initially planned (assume the below is now past tense)...

---

We're building an RCP app whereby a user can open and work with many files at once, but not in the same way users would do so right now in the Eclipse IDE (for example) we don't intend to show a file browser and we would like each open file to have one corresponding tab at the highest level possible in the UI (think Chrome/Chromium). This tab then has it's own things (views?) within it that presents a rich UI to work with the file (things like editors, palettes, consoles, etc). Each tab would maintain it's own instances of it's internal UI bits and it's own state, completely independent of the other tabs.

But now I think we may approaching this with the wrong concepts in mind; I didn't fully grasp that I couldn't add a view inside another view.

---

If anyone has been able to achieve the above with Eclipse RCP I'd be very grateful if they could share the details.

Thanks,
Jits

mmm. Interesting use case. The top level thing you describe is the Eclipse
perspective. I picture a small view all across the workbench with tabs
(chrome). Pressing a tab would trigger the opening of a perspective. The top
view with tabs is a so called sticky view (it will be seen across all
perspectives). The other views can then be positioned to your liking.

Are the "top level views" (perspectives) known beforehand?

I suggest you hire an Eclipse expert for one or two day to get you going.
This will be worth every penny. Did you attend the Eclipse RCP course?

Hi Wim,

Interesting suggestion. In our case we would need to instantiate the same perspective multiple times - one for each open file, which would be the dedicated "workspace" for that file. However, it doesn't sound like this is at all possible within the current framework. I guess the best thing is for us to "play nice" with the framework and do things the Perspectives/Views/Editors way Smile

As an aside, Sticky Views sound very handy. And I suspect we could make good use of them.

We haven't attended any courses nor hired any experts. Not certain if we're in a position to do so, as we are part of an academic/research team. So we are currently making do with the Eclipse RCP (2nd ed) book, online documentation and the advice/help from folks like yourself.

Thanks again,
Jits

Hey Jits,

I have an application that needs to be similar to yours. Essentially I will have high level tabs where each tab has its own perspective, views and editors. Each tab is a self contained mini application where the only thing common across all of them would be a log view(StickyView I guess) and the tab bar to switch between the different tabs.

Each of these high level tabs also needs to be able to detatch(like a View) from the main window.

So how would you guys solve this problem. Windows? Perspectives? Can a View contain other views and editors inside of it?

I am having a lot of trouble wrapping my head around this problem and I have no one to consult(I am alone on this project).

Will provide beer for help to those who are in the DC area Laughing
