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!
