[cdt-dev] lineChangedEvent

[Lefteris E <elefteris@xxxxxxxxxxx>]

Hi guys,

I am making a view add-on, and I want to update it's contents based on the current line of the active editor.

Is there a way to listen for line-changed events of the active editor? 

I tried ((ITextViewer)PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage().getActiveEditor().getAdapter(ITextOperationTarget.class)).getSelectionProvider().addSelectionChangedListener(  ...  );

hoping to track the curret possition but it only triggers when the selected text changes.

Following that I tried

((ITextViewer)PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage().getActiveEditor().getAdapter(ITextOperationTarget.class)).getTextWidget().addCaretListener( ... )

but it triggers whenever the curret moves, and I don't know how to get the current line information out of that.

thank you in advance,

Lefteris
