I am using OptionsGroup for star rating so to store the info in mysql table

OptionGroup group = new OptionGroup(" Star Rating");
group.addItem(“1 star”);
group.addItem(“2 star”);
group.addItem(“3 star”);
group.addItem(“4 star”);
group.addItem(“5 star”);
group.addStyleName(“horizontal”);
group.setSizeUndefined();
rightTopForm.addComponent(group);

How can i add listner to above so that on clicking info i can store the same in mysql.

Hi, you can add a
ValueChangeListener
 like the following:

group.addValueChangeListener(e -> { // your logic here }); Also, you may need to make the
OptionGroup
 immediate:

group.setImmediate(true);
