I have some issue with getSelectedRow. I can't make method that puts text from table's row to textfield. I tried to make table.setOnMouseClicked((MouseEvent event) -> {getTextFromSelectedRow();});
but everytime got Cannot infer functional interface type.
Help me please with that method. I need to get selected item from row when it's clicked.
And is it right that I do everything in Controller class?
