Use eval(“js”,code) to call this JavaScript code:
gd = new NonBlockingGenericDialog("YesNoCancel Demo");
gd.addMessage("This is a Non-blocking YesNoCancel dialog");
gd.enableYesNoCancel("Do something", "Do something else");
gd.showDialog();
if (gd.wasCanceled())
IJ.log("User clicked 'Cancel'");
else if (gd.wasOKed())
IJ. log("User clicked 'Yes'");
else
IJ. log("User clicked 'No'”);
