Hi,

I want to be able to get the current text cursor position in my
TextEditor when the user clicks in the editor to move the cursor where
the click occurs.

Thanks

Given your IEditorPart editor -

if (control instanceof StyledText)
{
final StyledText text = (StyledText) control;
text.addPaintListener(APaintListener);
}

within APaintListener:

public void paintControl(PaintEvent e)
{

IEditorPart editor =
PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActi vePage().getActiveEditor();

TextSelection selectedText = (TextSelection)
editor.getEditorSite().getSelectionProvider().getSelection() ;

int offset = selectedText.getOffset();
IDocument doc = ((ITextEditor)
editor).getDocumentProvider().getDocument(editor.getEditorIn put());
int line = doc.getLineOfOffset(offset);

}

the int line will have the current line number
