Eclipse e4 disable close in shared element

I created a part as shared element. and it is used as placeholder with no closeable on the part stack.

But at launching the e4 application I saw that close button on placeholder is enabled (like 'X').

Why doesn't the placeholder apply the closeable option?

Solution

  • The code in the stack renderer for determining the close flag is:

    protected boolean isClosable(MPart part) {
    // if it's a shared part check its current ref
    if (part.getCurSharedRef() != null) {
        return !(part.getCurSharedRef().getTags().contains(IPresentationEngine.NO_CLOSE));
    }

    return part.isCloseable();
}

    And the JavaDoc for IPresentationEngine.NO_CLOSE (value `"NoClose") says:

    When applied as a tag to an MPlaceholder inhibits the display of the close affordance. This allows a part to be closeable in one perspective but not in a different one
