Hi all

I can't seem to figure out how to change perspectives in the new 4.0 framework. I have created two different perspectives in the e4xmi file and would like to be able to switch between them dynamically.

Could somebody please point me in the right direction or maybe even provide example code.

Best regards
Christian

You need to set the selectedElement in the PerspectiveStack.

Thanks for your reply Tom.

I now how to do that in the e4xmi file. But how do I do it in code? For instance if something is selected (by the user) in my application that makes me want to display another perspective.

You can have a look at
/org.eclipse.e4.ui.workbench.addons.swt/src/org/eclipse/e4/u i/workbench/addons/perspectiveswitcher/PerspectiveSwitcher.j ava
and that bundle's extensions to see how we do it in the compatibility layer

Thanks to both of you for helping. I tried to work with the example Tom provided and ended up with something like this:

@Inject private MPerspective perspective;

MElementContainer<MUIElement> stack = (MElementContainer<MUIElement>) perspective.getParent();
for( MUIElement p : stack.getChildren() ) {
System.out.println("PER: " + ((MPerspective)p).getLabel());
if (((MPerspective)p).getLabel().equals("Tokens")) {
stack.setSelectedElement(p);
}
}

I couldn't get the perspective stack injected for some reason.
