P2 UI menu contributions in E4 application [message #551196]

Thu, 05 August 2010 10:53

Eclipse User

Hello,

In a 3.6 application, adding p2 feature UI was sufficient to have "Install new Software..." and "Check Update..." in "Help" menu.

Now, my application is E4. It doesn't work anymore. Even if I have a menu with id=help in Application.e4xmi and a separator with id=additions.

My question is : does old 3.6 contributions system work with E4 application ?

Thanks.

For information, the contribution of P2 UI DK is :

<extension
point="org.eclipse.ui.menus">
<menuContribution
locationURI="menu:help?after=additions">
<command
commandId="org.eclipse.equinox.p2.ui.sdk.update"
mnemonic="%Update.command.mnemonic"
id="org.eclipse.equinox.p2.ui.sdk.update">
</command>

</menuContribution>
<menuContribution
locationURI="menu:help?after=org.eclipse.equinox.p2.ui.sdk.update ">
<command
commandId="org.eclipse.equinox.p2.ui.sdk.install"
mnemonic="%Install.command.mnemonic"
id="org.eclipse.equinox.p2.ui.sdk.install">
</command>

</menuContribution>
</extension>

Hi,

Well those things only work if you have the compat-layer with you.

An application built with the pure Eclipse 4.0 Application Platform does
not understand any extension points beside:
* org.eclipse.e4.workbench.model: for model contributions
* org.eclipse.e4.ui.css.swt.theme: to contribute themes and styles

That's all extension points you need to make up complete applications -
we don't need more than those because the
org.eclipse.e4.workbench.model-extension points allows to contribute
model fragments and the model itself knows about, commands, handlers, ... .

Not sure about what you meant, does the compat-layer enable to use 3.6 plugins in an E4 application ? I guess the compat layer "converts" 3.6 extension points contributions to e4 modelled UI elements. When you say "pure Eclipse 4.0 Application Platform does not understand any extension points", I guess this is true when not using the compat-layer.

Now supposing the compat-layer does allow 3.6 plugins in e4 applications, I tried to include the P2 features "Install new Software..." and "Check Update..." in an E4 application (as probably Chris did) and included the compat-layer bundle (org.eclipse.ui.workbench). This does not seem to work better, I can't get the P2 menus.

Is there something more to do to activate the compat-layer, or something to setup in my xmi application model ? or do I simply misunderstood the purpose of the compat-layer ?

Thanks
Sun

You need to use the normal workbench start up process and Legacy.e4xmi
and not the standard E4 Application.

The bug referenced above describes how to get a 3.x style application
running and reuse bundles from e.g. p2

Thanks, it works better !

Now I have the next question : I want to extend the legacy model in the e4-way, by contributing to the org.eclipse.e4.workbench.model extension point : change the perspective, adding my own views, etc.

But I noticed that the model extension processor I declared is called *before* the 3.x plugins have populated the legacy model.

Is there a way to force the e4 model extensions to be activated *after* the compat-layer has populated the legacy model from the 3.x plugins ? or must I use the 3.x style extension points.

unfortunately no, something we'll hopefully find a solution in 4.1.

All you can do is to contribute PartDescriptors because they are stored
at in the Application-Element. Does the legacy implementation come with
a Window and PerspectiveStack-Element. If yes you can also makeup a
complete Perspective.

Yes this would be great, the e4 way is so nice and simple Smile

Unfortunately no, it only comes with a Window and nothing under it. And trying to programmatically add a perspective stack in the processor leads to errors.

So I will probably reswitch to a pure E4 application, and try to make P2 work at least for updates (that was the initial purpose of integrating the P2 UI plugin), with a simple homemade UI.

Thanks for answering so fast,

Well you simply add your own commands and call the P2 CORE API.
