How to add functionality to an existing View using a PlugIn [message #671035]

I have setup pre-configured View with a CTabFolder. The view id would be ViewTests.ID. I then want to use the idea of PlugIns to add functionality to the existing View by adding a CTabFolder and it data or chart that will be built from a database extraction. I would like to "drop" these various pieces of data analysis into the RCP app by way of PlugIns so that each of the many Views can grow depending on the type of data that each individual client has without rebuilding the app. My newbee problem is I don't see an Extention Point that will let me contribute (in this case - a tab with its functionality to an existing view that contains the parent CTabFolder). Can anyone suggest if this can be done and if so what extention point that I should look at and/or any prototype that might give some hint as to how to proceed.

Just to be clear - I want the PlugIn to contribute significant functionality to an existing View by adding a tab to the views existing CTabFolder.

Thanks

You would be writing your own extension point, and then reading it using org.eclipse.core.runtime.Platform.getExtensionRegistry(). Then you would have to create the extra CTabItems yourself based on the extensions that you read.

The simplest form of working with the extension registry looks like:

final IExtensionRegistry registry = Platform.getExtensionRegistry();
final IConfigurationElement[] menusExtensionPoint = registry
		.getConfigurationElementsFor(EXTENSION_MENUS);
for (int i = 0; i < menusExtensionPoint.length; i++) {
    // do stuff with the IConfigurationElements
}

Paul,

Thanks for the quick response. Now that I now that its possible I can start move ahead and see if I can implement a variation of what you have provided.
