how to add curvy tab in eclipse 4 RCP app

eclipse, eclipse-rcp

Solution

This should be managed through the E4 CSS engine, and your associated CSS stylesheet for your RCP app should include something in the lines of:

.MPartStack {
  swt-tab-renderer: null;
  swt-selected-tabs-background: #FFFFFF #ECE9D8 100%;
  swt-simple: true;
  swt-mru-visible: true;
}

(from the page "Eclipse4 CSS", so it is for Eclipse4 itself, but could apply to your RCP as well)

If you have a `swt-simple: false;`, you should see curvy tabs.

Problem
