Re: [ jEdit-users ] Macro question

[Alan E. <ala...@gm...>]

You can see the code in JEdit that updates that info in StatusBar.java,
function "updateCaretStatus()".

In particular, these lines seem relevant:


            JEditTextArea textArea = view.getTextArea();

            int caretPosition = textArea.getCaretPosition();
            int currLine = textArea.getCaretLine();

            // there must be a better way of fixing this...
            // the problem is that this method can sometimes
            // be called as a result of a text area scroll
            // event, in which case the caret position has
            // not been updated yet.
            if(currLine >= buffer.getLineCount())
                return; // hopefully another caret update will come?

            int start = textArea.getLineStartOffset(currLine);
            int dot = caretPosition - start;

            if(dot < 0)
                return;

            int bufferLength = buffer.getLength();

            buffer.getText(start,dot,seg);
            int virtualPosition = StandardUtilities.getVirtualWidth(seg,
                buffer.getTabSize());
            // for GC
            seg.array = null;
            seg.count = 0;

            if
(jEdit.getBooleanProperty("view.status.show-caret-linenumber", true))
            {
                buf.append(currLine + 1);
                buf.append(',');
            }
            if (jEdit.getBooleanProperty("view.status.show-caret-dot",
true))
            {
                buf.append(dot + 1);
            }
