How to add a toolbar with a button through e4xmi

Question

I have a task to redesign the toolbar of an eclipse-based application. The previous implementation is based on the e3 plugin.xml extension points.

I saw that the application uses an .e4xmi file to add extensions to the eclipse Menu , therefore I'd like to migrate all the toolbars and added buttons to be extended from the e4xmi file.

How can I create a toolbar and add a button to it from the e4xmi file? I can't find a documentation for migrate a button from e3 to e4 ...

Answer 1

E4 uses more generic TrimBar "representing the trim along a Window's edge" to express ToolBar, StatusBar and so on. Please have a look here to learn more https://www.vogella.com/tutorials/EclipseRCP/article.html#toolbars-toolcontrols-and-drop-down-tool-items

I would give E4 a chance, especially for new things.
