The update() method on a view may be called a lot, including circumstances when the state of the view is already fine. Try to avoid UI mutations or expensive calls like revalidate() unless required.

E.g. In DishAddOnView.java's update method we have:

@Override
    public void update() {
        if (isSelected){
            getStyle().setBgTransparency(255);
        }else{
            getStyle().setBgTransparency(0);
        }
        revalidate();
    }

I would guard against both the setBgTransparency() calls and the revalidate, as follows:

@Override
    public void update() {
        int bgTransparency = getStyle().getBgTransparency();
        if (isSelected && bgTransparency != 255){
            getStyle().setBgTransparency(255);
            revalidateWithAnimationSafety();
        }else if (!isSelected && bgTransparency != 0){
            getStyle().setBgTransparency(0);
            revalidateWithAnimationSafety();
        }

    }

Note: Also prefer revalidateWithAnimationSafety() to revalidate() in almost all cases. The only exception is when you are calling revalidate() to update layout and you need to access the updated layout coordinates immediately. The difference is that, if there is an animation in progress, revalidate() may cause it to be janky as it will interrupt the transitions.

If you want to embed your own custom back button into a View, you can simply fire a FormBackEvent. This will automatically be propagated up the controller hierarchy and handled by the form controller to go "back" to the parent controller.

E.g.

Button back = new Button();
back.addActionListener(evt->{
    evt.consume();
    ActionSupport.dispatchEvent(new FormController.FormBackEvent(back));
});

E.g. You could use this pattern in your back button in the DishView class.

Hello, All
I thought this project is java/kotlin code for android
But It seems not android
Please let me know where can I find android source code?
Thanks

This might be a bug in CN1's lead component handling, but the DishPreview isn't firing the event when the user clicks on the image. CN1 is having trouble handling the nested lead components (DishPreview's lead component is the nested MultiButton, but MultiButton itself is a container with a lead component).

To work around this problem, create a dummy Button in the DishPreview and set it as the lead component. Then add the actionListener to both the multibutton and the dummy button.

E.g.

Button lead = new Button();
lead.setVisible(false);
add(BorderLayout.SOUTH, lead);
setLeadComponent(lead);
....

$(lead, dishPreview).addActionListener(evt -> {
            evt.consume();
            ActionNode action = viewNode.getInheritedAction(DISH_CLICKED);
            if (action != null) {
                System.out.println("DISH_CLICKED action fired");
                action.fireEvent(entity, DishPreview.this);
            }
        });

Anyone can help me?

Admin panel to manage restaurants, drivers, commissions, payment methods and payment distribution to restaurants?

Hello, im wondering if there is a agent app aswell, so the delivery guy can see and pickup the orders. If not, can you recommend me something please? Thanks in advance

Android studio and IDEA by intellij used but it keeps saying module not specified, despite resyncing and clearing cache.

Conceptually there needs to be an OrderModel with the details of the order. This would include which dishes are being ordered, quantities, and add-on choices for the dish.

This will affect some aspect of the views. For example, the DishAddOnView has a boolean property isSelected that you track internally in the view and update when the button is selected/deselected. This state should be stored inside a model. Depending on how you want to design the model, you might have a "selected" property in the DishAddOn model and just bind on that.

If you find yourself adding state variables inside a View class (other than just to help with determining if it is in-sync with the model), then it is an indication that the model needs to be adjusted to store that state instead.

Comment below if you have a back-end solution all in box for that app
