e4: Find a placeholder [message #551984]

Hello,

I realise an e4 application divided in 2 parts:
- the main UI, configured whith an e4xmi file containing a placeholder in a Part Stack.
- a bundle with a view which must display a form in the placeholder.

(The main UI invoque the bundle using services.)

How can I find the declared placeholder in the bundle in order to place my view in the main UI? have you got a code exemple ?

Thanks.

I'm not sure I understand about which placeholder you are talking
because the Placeholder-Element is a very special type so that we can
share UI-Subtrees. I don't think that's what you are after, right?

If you are NOT sharing Subtrees between different areas you DON'T need
placeholders but contribute an MPart to the parent-container.

The ID you need to contribute is found in the elementId of the parent.

In my RCP-Tutorial [1] I show how to contribute elements from other
bundles through the so called fragment.e4xmi.

Thank you very much. Your tutorial is very useful.

I need to share an area in order to edit some data depending node tree selected in the main GUI.

e.g: I have a tree with nodes representing cars and planes.
When I select a car, a form displays its specific features.
When I select a plane, another form displays its specific features too, but the form is different.

Your tutorial show how to open another indepedant view. How can I integrated my view in the main GUI ?

Well if the view should open dynamically you first have to define a
MPartDescriptor in your model and then you can use the EPartService to
show the view below any container (MPartStack,MPartSashContainer).

The SimpleIDE-Demo in CVS holds an example of a MPartDescriptor in
/cvsroot/eclipse/e4/org.eclipse.e4.ui/examples/org.eclipse.e 4.demo.simpleide.iconview.

The important thing to define which container should be used when an
MPart-instance is to be shown, is to set the "category"-attribute to the
id of the container. Afterwards all you need to do is to call:

-------8<-------
EPartService s ....
s.showPart("element.id.of.the.descriptor",PartState.ACTIVATE);
-------8<-------
