Hello! So i have a gui and what i am trying to accomplish is that after i click the add to cart button, the stock available in the item description needs to be reduced. I am unsure of how to get it to update dynamically based on the stock that is available in the inventory.

just save bodylabel somewhere and then use bodylabel.setText("Your new text"); to update the text – IntoVoid Mar 29 '21 at 15:47

Also please switch to IntelliJ (https://www.jetbrains.com/idea/) instead of JavaEditor. IntelliJ is so much better and will help you code – IntoVoid Mar 29 '21 at 15:50

Don't dynamically add components (like the label). Declare it as an attribute of the class and simply call `setText("the HTML..")` when the content needs to change. – Andrew Thompson Mar 29 '21 at 15:52
@Ruskin Janowski you said it twice ;) – IntoVoid Mar 29 '21 at 16:01
