I have my Eclipse RCP application created on Eclipse 3.7 . But in order to use Eclipse e4 CSS Styling and for some other reasons, We want to migrate our application to Eclipse e4(4.1.2) version. In doing so, I have tried moving my code to Eclipse e4 4.1.2 and when I run my RCP application now it gets launched but it is showing these unwanted Coolbar/Toolbar items/preference pages which I was hiding through code in my overriden method WorkbenchWindowAdvisor.postWindowCreate(). On some digging into the issue I found out that

WorkbenchWindowAdvisor.postWindowCreate()

method is not used in e4 and it does not get called at all. So what is the alternative way of doing this in Eclipse e4?

Additionally what all things I need to do and know about migrating from Eclipse 3.7 to eclipse e4? as there could be more such issues in migration.

You can:
a) use a custom Legacy.e4xmi file which has none of those items
b) use a model processor to remove those items programmatically from the
model

I've not tried those possibilities but I think they could work.

Thanks for your reply Tom, As I have migrated(directly moved without any changes) my code that was developed on Eclipse 3.7 to Eclipse 4, so I do not have Legacy.e4xmi file already present. I am a novice to Eclipse 4 and want to know:

Is simply moving the code like this from 3.7 to e4 is the correct way of migrating ? Or do I need to do something more?
How do I get Legacy.e4xmi file?

The compat layer is falling back to a Legacy.e4xmi if you are not
setting a custom one.

I need to look up where it is located later and come back to you once I
figured it out.

The LegacyIDE.e4xmi file is located here: ./eclipse.platform.ui/bundles/org.eclipse.ui.workbench/LegacyIDE.e4xmi

In addition to Toms proposal ou should be able to use a Lifecyle hook to remove the items. The Lifecycle hooks are described here: Eclipse 4 Tutorial - Lifecycle

Lifecycle will not work, see Bug - Eclipse 4 IDE not extendable via fragments or processors

I document the mixed mode a little bit here: Eclipse 4 Compatibility Mode

Hi Tom & Lars,

I tried using a custom Legacy.e4xmi file, but have no clue about how to edit that, neither found any documentation about it. I tried to modify it but still seeing Run and Search menus. Could you please let me know about what to change in Legacy.e4xmi file to remove the menubar all together and some of the toolbar items. I also want to mention that in my RCP application I am having an Xtext plugin, if that makes any difference.

Install the e4 tools - I think you'll find how to install it in the
tutorials from Lars Vogel.

hi Lars & Tom,

Thanks for the information. I installed e4 tools on my Eclipse 4.2 and was able to change stuff in Legacy.e4xmi file. But even if I make the menu bar invisible or mark toBeRendered as false, and then first time when I launch the Application, it does not show the Menu bar, which is correct, but when I relaunch it without making any change then it starts showing the Menu bar with Search and Run menu items. And I am unable to figure out from where they are coming from.
Note: I also want to mention that in my RCP application I am having Xtext plugin.
