Eclipse4/RCP/Modeled UI/Tags

Most model elements support additional annotations called "tags". These tags are free-form strings; the model renderer may interpret certain tags to configure how an element is to be rendered. Several of these tags are defined on IPresentationEngine.

MPart

A part can be annotated with a "NoMove" tag to indicate that the DND mover should not support moving this part. (Defined by IPresentationEngine#NO_MOVE)

MPartStack

Parts within a part stack can be annotated with a NoClose tag to indicate that the part should not be closeable. The SWT Renderer will configure the corresponding CTabFolder to not display an "X" to close the part. (Defined by IPresentationEngine#NO_CLOSE)

Parts within a part stack can be annotated with a NoTitle tag to indicate that the part should not have a rendered title. (Defined by IPresentationEngine#NO_TITLE)

MTrimBar

A TrimBar will replace ToolControls with a "stretch" tag with stretchable space. A ToolControl with "glue" will ensure its siblings are kept together on the same line. The following example will cause the "find" control to be placed flush right:

<menu:TrimBars>
    <menu:ToolControl contributionURI="platform:/plugin/blah/blah">
        <tags>stretch</tags>
    </menu:ToolControl>
    <menu:ToolControl elementId="com.example.find" contributionURI="platform:/plugin/com.example.find/com.example.FindTextField"/>
</menu:TrimBars>
