Help system in e4 [message #663702]

Hello,

I found a lot of tutors on the net how to set up an help system in a eclipse 3.x rcp app. My question how is this done in an eclipse e4 app.

I use the Applicatione.4XMI file to create a menu, command and handler. After that i open my handler code and ...

In the tutors the code: Platformui.getworkbench().gethelpsystem() comes up to open the help system.

I don't think e4 uses this approach anymore so how to invoke the helpsystem in a native e4 application without compatability layer.

Thanks for the help.

I think the help system is currently not supported in Eclipse 4.2.

The help system is in Eclipse 4.2 (the workbench) but it is not available in the E4EAP, Eclipse4 based applications.

Has there been any progress made in making the help system available in eclipse 4 applications?

If not, is there a recommended way of embedding the eclipse 3 system in an v4 application?

Thanks all.

I think you are mixing up e4 framework with Eclipse 4.x workbench products.

Eclipse 4.x (the workbench) already has the help system - the same one
that is available to Eclipse 3.x through the compatibility layer.

e4 - (the framework) has no such thing. And is not very likely to get
one in a short while. But it has all the building blocks afailable for
you to build one, if that is what you need.

Hi Roland,

I'm also trying to find a way to reuse helpsystem in pure e4 application on Kepler. It seems there is no easy way. You mentioned building blocks are there for creating such help UI, could you tell me more detail? what're them? and does the target UI contain function like index, search, bookmark in E3 by default? Many thanks.

Has anybody managed to add a help system to a pure E4 RCP application? I am using Eclipse 4.3 and I have no idea of how to implement this.

It may well be possible to scrape most of the useful code out of the existing Eclipse IDE, leaving behind all the trailing IDE references. The reason that it's been sooooo hard to port existing views / commands / Help System to e4 is that the nature of the API defined for eclipse is *highly* self-referential, making it nearly impossible to split off the functionality from the framework (i.e. the second you reference any of IWorkbench[Window | Page] you're doomed because those interfaces directly reference not only each other but almost all of the IDE's services...).

Most of it seems to be a fairly straightforward contract where the 'context' (current Dialog / part...) defines the
current 'HELP_ID' which is then used to look up the proper URL / local html...
