How to select row in ImageJ ResultsTable?

Question

From an ImageJ plugin, I would like to highlight a row in a ResultsTable, like when the row is clicked with the mouse. I suppose that the function ResultsTable.selectRow(Roi roi) can do this, but I do not know how to specify the row number using a Roi. How to create a Roi for this?

Answer 1

Here is a code snippet to select a row by index:

import java.awt.Frame;
import ij.WindowManager;
import ij.text.TextWindow;
...
int index = ...; // row index to highlight
Frame frame = WindowManager.getFrame("Results");
((TextWindow)frame).getTextPanel().setSelection(index, index);

I adapted it from the ResultsTable source code.
