UI Toolkit

[Roland2TowerCame]

I thought it might be related to this: http://community.eu.playstation.com/t5/PS-Suite-UI-Composer/Button-s-BackgroundFilterColor/td-p/1489... but even after changing a button's color, it doesn't show up, but two Labels and a PopupList do.

Hi Roland2TowerCame (nice name!),

Do you have any code snippets that we can look at to help you determine why it's not displaying?

Some simple suggestions:-
- Is the Button X,Y position inside the screen?
- Are you setting the .visible property to false?
- Are your other widgets covering it?

Thanks

Check the order in which the button is being added in the generated .composer.cs file

I've posted about an issue I've encountered which could be the cause :

Bug?

Thanks!  None of the simple suggestions apply.  Non-button widgets show up fine (at least labels and popuplists do).

namespace VCalc
{
    public class AppMain
    {
        private static GraphicsContext graphics;
        
        public static void Main (string[] args)
        {
            Initialize ();

            while (true) {
                SystemEvents.CheckEvents ();
                Update ();
                Render ();
            }
        }

        public static void Initialize ()
        {
            // Set up the graphics system
            graphics = new GraphicsContext (960, 544, PixelFormat.None, PixelFormat.None, MultiSampleMode.None);
            UISystem.Initialize(graphics);
            Scene calcScene = new mainview();
            UISystem.SetScene(calcScene, null);
        }

        public static void Update ()
        {
            // Query gamepad for current state
            var gamePadData = GamePad.GetData (0);
        }

        public static void Render ()
        {
            // Clear the screen
            graphics.SetClearColor (.50f, .50f, .50f, 1.0f);
            graphics.Clear ();
            
            // Render the UI
            UISystem.Render();

            // Present the screen
            graphics.SwapBuffers ();
        }
    }
}

From the generated code:

// Scene
            sceneBackgroundPanel.BackgroundColor = new UIColor(168f / 255f, 206f / 255f, 238f / 255f, 255f / 255f);

            this.RootWidget.AddChildLast(sceneBackgroundPanel);
            this.RootWidget.AddChildLast(Button_0);
            this.RootWidget.AddChildLast(Button_1);
            this.RootWidget.AddChildLast(Button_2);
            this.RootWidget.AddChildLast(Button_3);
            this.RootWidget.AddChildLast(Button_4);
            this.RootWidget.AddChildLast(Button_5);
            this.RootWidget.AddChildLast(Button_6);
            this.RootWidget.AddChildLast(Button_7);

I failed to call this
// Update UI Toolkit
UISystem.Update(touchDataList);
didn't realize it was necessary.

Button overrides OnUpdate but Label and PopupList do not
it seems this functionality is what helps with having different images for Normal, Pressed, and Disabled.
