@Shai According to the image below got from CleanMordern Project.
how can I style my radio buttons using CSS to look exactly as Shai did his,
and also make actions on each button to show different container when pressed
ButtonGroup barGroup = new ButtonGroup();
RadioButton all = RadioButton.createToggle("All", barGroup);
all.setUIID("SelectBar");
RadioButton featured = RadioButton.createToggle("Featured", barGroup);
featured.setUIID("SelectBar");
RadioButton popular = RadioButton.createToggle("Popular", barGroup);
popular.setUIID("SelectBar");
RadioButton myFavorite = RadioButton.createToggle("My Favorites", barGroup);
myFavorite.setUIID("SelectBar");
Label arrow = new Label(res.getImage("news-tab-down-arrow.png"), "Container");
add(LayeredLayout.encloseIn(
GridLayout.encloseIn(4, all, featured, popular, myFavorite),
FlowLayout.encloseBottom(arrow)
));
You can open the theme file in the designer tool and just copy the styling from there. I implemented this using image backgrounds to keep some pixels free for the arrow on the bottom.
If you look at the theme you will see I just placed a background image that's solid red on top and has a white bottom. Then I have a separate "arrow" image which is animated with the code to the selected button on every click. Everything else is just colors and fonts which is trivial.
