Re: [pdt-dev] can i get ISourceModule from IStructuredDocumentRegion

[赵忠伟 <zhaozhongwei@xxxxxxxxxxxxxxxx>]

thanks for your reply.i think it is executed in non-ui thread ,and the result is (page == null),as i use the following code.

 

//   IWorkbench workbench  = PlatformUI.getWorkbench();
//   IWorkbenchWindow window = workbench.getActiveWorkbenchWindow();
//   IWorkbenchPage page  = window.getActivePage();
//   IEditorPart editorpart = page.getActiveEditor();
//   if(editorpart instanceof PHPStructuredEditor){

but i think i have some other method to get the edtior.descript as following:

 

PHPStructuredEditor#createStructedTextViewer

 protected StructuredTextViewer createStructedTextViewer(Composite parent, IVerticalRuler verticalRuler, int styles) {
  PHPStructuredTextViewer structuredTextViewer = new PHPStructuredTextViewer(this, parent, verticalRuler, getOverviewRuler(), isOverviewRulerVisible(), styles);
  structuredTextViewer.addTextInputListener(new ITextInputListener(){
  
   public void inputDocumentChanged(IDocument oldInput, IDocument newInput) {

//do some operation
   }
  
   public void inputDocumentAboutToBeChanged(IDocument oldInput, IDocument newInput) {
   }
  });
  return structuredTextViewer;
 }
i do some operations to put the current PHPStructuredEditor instance and IDocument to two global maps(they map to each other in a thread save way) .,and remove them when the editor is disposed.

 

so in  ISemanticHighlighting#consumes i can get the IDocument :

IStructuredDocumentRegion sdRegion;
IStructuredDocument parentDocument = sdRegion.getParentDocument();

 

and then through the global map,i think i can make it. i think it is a very poor way!

In this case you can do the following hack :)

IStructuredDocumentRegion sdRegion;
IStructuredDocument parentDocument = sdRegion.getParentDocument();
IWorkbenchPage page = PHPUiPlugin.getActivePage();
if (page != null) {
       IEditorPart editor = page.getActiveEditor();
       if (editor instanceof PHPStructuredEditor) {
               ISourceModule sourceModule = (ISourceModule) ((PHPStructuredEditor)
editor).getModelElement();

       }
}
