Hello world! I'm illustrating checkboxes and radio buttons using a buffet restaurant example. I've started a new program called buffet. And I want to have a choice of breakfast, lunch, or dinner, and also a choice for your age group of child, adult, and senior. If I put all of the radio buttons on the form, They'll make one and I can only check breakfast or child, Not a child and breakfast both. In order to make separate groups of the radio buttons, we need a container. Aand I'm going to use a group box, That's one container. And I'm going to take this group box and put radio buttons inside it. So, I'm going to take a radio button and drag it inside the group box. And I need three of those: for breakfast, lunch, and dinner. And then let's move that group box and make sure that those [Labels], those radio buttons move with it: that shows me that they are in there. And then I'm going to make the group box text say "Meal" And let's name that GRP meal, (grpMeal) and then the radio buttons: radBreakfast, and the text will say "Breakfast", and this one is going to be lunch, let's name that radLunch. Then we have radDinner [typing] And just make that a little smaller there, and then I'm going to have another group box, For... let's call it age or something like that, and then put the radio buttons inside. For child, adult, and so this group box is going to say Oh, I need properties window, age. Change that to age. This button is going to say child, and that radChild. radAdult and, Make that one say adult, and this is senior. [typing] text. When we run this, you'll see I can pick one of these... And I can also pick one of these. If I just put them all on the form without the group boxes I could pick one out of the entire six. In the next video We'll calculate the price for the meals with this program.
