Hi,
Trying to do something like the following, but dun really know where to
start.
I would like to create something like the Task View, (or maybe make use of
the existing Task View) to display TODO items for each individual Figure.
Say, I create a new Figure on the editor, it will automatically generate a
list of TODO items. When I select this figure, the TODO list will be
displayed in a View (eg. Task View?). Double clicking on each TODO item
will trigger some action (say, bring up a dialog for user input eg.), and
once the user has completed the task, the changes will be updated to the
editpart and to the model.
Is there an article I can read or some advice as to how to go about this?
Thanks...
Regards,
Lee

Hi Nicole,
I have solved this issue in my project so here is a sample code to show
you how to deal with markers :
1) You should implement the gotoMarker method in your editor:
class MyEditor extends GraphicalEditorWithPalette implements
org.eclipse.ui.ide.IGotoMarker{
public void gotoMarker(IMarker marker_p) {
try {
String nmsObjectID = (String)
marker_p.getAttribute("objectID");
_
// The keys are model objects and we are looking for the rigth
editPart
Map editPartRegistry =
getGraphicalViewer().getEditPartRegistry();
Iterator iteratorOnKeys = editPartRegistry.keySet().iterator();
boolean found = false;
ArrayList selectedPart = new ArrayList();
while (iteratorOnKeys.hasNext() && !found) {
TopologyElement subPart = null;
Object object = null;
// Be careful, some keys are not model object but ????
try {
object = iteratorOnKeys.next();
if (object instanceof TopologyElement)
subPart = (TopologyElement) object;
} catch (ClassCastException e) {
}
if (null != subPart) {
ModelElement element = subPart.getModelObject();
if (null != element) {
String elementID = element.getID();
if (elementID.equals(nmsObjectID)) {
found = true;
AbstractEditPart editPart = (AbstractEditPart)
editPartRegistry.get(subPart);
selectedPart.add(editPart);
}
}
}
}
// let's show the retrieved editPart
if (!selectedPart.isEmpty()) {
StructuredSelection selection = new
StructuredSelection(selectedPart);
getGraphicalViewer().setSelection(selection);
}
} catch (CoreException e_p) {
_logger.error("TopologyEditor.gotoMarker()", e_p);
}
}
}
2) Defining your marker in your plugin.xml associated to your editor, to
be able to retrieve objects
<extension
id="myProblemMarker"
name="%problemName"
point="org.eclipse.core.resources.markers">
<super
type="org.eclipse.core.resources.problemmarker">
</super>
<attribute
name="objectID">
</attribute>
</extension>
3) Save the IFile as a IResource from MyEditor.setInput(IEditorInput
input){
IFile file = ((IFileEditorInput) input).getFile();
IResource resource = file;
}
4) call the method below with the rigth parameter when your code detects
an error. (your checkMethod may be called in your listener class for
instance in LogicalEditPart when a object's attribute changes)
/**
* Create a Problem Marker
* @param resource_p The resource_p for which we are creating a new
Marker
* @param severity_p the severity for this problem
* @param priority_p the priority to fix the problem
* @param objectID_p the object's id producing the error
* @param message_p a user friendly string describing the problem
*/
public void createProblem(IResource resource_p, int severity_p, int
priority_p, String objectID_p, String message_p) {
try {
IMarker marker =
resource_p.createMarker("org.testmarker.myexemple.myProblemMarker ");
marker.setAttribute(IMarker.SEVERITY, severity_p);
marker.setAttribute(IMarker.MESSAGE, message_p);
marker.setAttribute(IMarker.PRIORITY, priority_p);
marker.setAttribute("userEditable", false);
marker.setAttribute("objectID", objectID_p);
} catch (CoreException e) {
_logger.warn("MarkerHandler.createProblem(),", e);
}
}

Hi
I have implemented the IGotoMarker Interface in myEditor (Graphical Editor) and written the implementation code for the gotoMarker Method, but when i click the problem displayed in the problemview, the gotoMarker method is not called.
I have added the following code in the getAdapter() of my Editor
if( type.equals( IGotoMarker.class ) )
{
return this;
}
Kindly let me know what can be done for this problem.
