Marker Help

Identifier:
org.eclipse.ui.ide.markerHelp

Since:

This extension point is used to associate a help context id with a specific "kind" of marker (a marker of a certain type or having certain attribute values).

Configuration Markup:

<!ELEMENT extension ( markerHelp*)>

<!ATTLIST extension

point CDATA #REQUIRED

id    CDATA #IMPLIED

name  CDATA #IMPLIED

>

  • point - a fully qualified identifier of the target extension point
  • id - an optional identifier of the extension instance
  • name - an optional name of the extension instance

<!ELEMENT markerHelp ( attribute*)>

<!ATTLIST markerHelp

markerType    IDREF #IMPLIED

helpContextId CDATA #REQUIRED

>

  • markerType - the unique type of the marker for which the help context applies.
  • helpContextId - the unique id of the help context.

<!ELEMENT attribute EMPTY>

<!ATTLIST attribute

name  CDATA #REQUIRED

value CDATA #REQUIRED

>

  • name - the name of the attribute whose value is being specified.
  • value - the specified value of the attribute.

Examples:
The following is an example of a marker help extension (note the sub-element and the way attributes are used):


 <extension point=
"org.eclipse.ui.ide.markerHelp"
>
  <markerHelp
   markerType=
"org.eclipse.ui.examples.readmetool.readmemarker"

   helpContextId=
"org.eclipse.ui.examples.readmetool.marker_example1_context"
>
   <attribute name=
"org.eclipse.ui.examples.readmetool.id"
 value=
"1234"
/>
  </markerHelp>
 </extension>

In the example above, a help context id is associated with markers of type org.eclipse.ui.examples.readmetool.readmemarker whose org.eclipse.ui.examples.readmetool.id attribute has a value of 1234.
