Step 3: Set up the Stage Layout
Now we are going to create the display for our file selector. We will be using the Combobox, Label, and Loader components. Drag an instance of each one of these onto the stage and arrange them appropriately. Add static text fields to the left for descriptions. Our combo box’s instance name will be image_cb, our Label’s instance name will be fileName_lb, and lastly our Loader instance name will be preview_ldr.
