customise plugin.xml [message #1745460]

Hi,
I'm creating an idea plugin, and I want to customise the oultine.
I found that instruction in plugin_gen.xml :

		<lang.psiStructureViewFactory 
			language="MyLanguage"
			factoryClass="MyLanguageExtensionFactory"
			implementationClass="com.intellij.lang.PsiStructureViewFactory"
		/>

How do I instruct the plugin to use my own implementation (something like MyLanguageStructureViewFactory) instead of com.intellij.lang.PsiStructureViewFactory ?

Is there another way to create a custom outline view in idea ?

Thanks
Herve

Xtext uses dependency injection to set up the infrastructure of your language.
The MyLanguageExtensionFactory makes sure that the injector is used to create an instance of the implementationClass at runtime.

In order to get your implementation in, you have to extend PsiStructureViewFactory, and bind your implementation to the class PsiStructureViewFactory in the MyLanguageIdeaModule, e.g. by adding

Class<? extends PsiStructureViewFactory> bindPsiStructureViewFactory() {
return MyLanguageStructureViewFactory
}

See also the Xtext documentation on dependency injection.
