Hover image button in data template of collection view provide cursor hand

Question

Hi,

Why the bold is :

Microsoft.UI.Xaml.Controls.Button btn = (Microsoft.UI.Xaml.Controls.Button)handler.PlatformView;

and not(not complied)

Microsoft.UI.Xaml.Controls.ImageButton = (Microsoft.UI.Xaml.Controls.ImageButton)handler.Platform

Microsoft.Maui.Handlers.ImageButtonHandler.Mapper.AppendToMapping("Custom", (handler, view) =>
            {
#if WINDOWS
            ImageButton button = handler.VirtualView as ImageButton;
            button.HandlerChanged    += (sender, args) =>
            {
                Microsoft.UI.Xaml.Controls.Button btn = (Microsoft.UI.Xaml.Controls.Button)handler.PlatformView;
                btn.Loaded += (s2, e2) =>
                {
                    MainThread.BeginInvokeOnMainThread(() =>
                    {
                        btn.ChangeCursor(Microsoft.UI.Input.InputSystemCursor.Create(Microsoft.UI.Input.InputSystemCursorShape.Hand));
                    });
                };

            };
#endif

public static class ElementExtension
    {
#if WINDOWS
        public static void ChangeCursor(this UIElement uiElement, InputCursor cursor)
        {
            Type type = typeof(UIElement);
            type.InvokeMember("ProtectedCursor", BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.SetProperty | BindingFlags.Instance, null, uiElement, new object[] { cursor });
        }
 #endif

Hello,

This is because the ImageButton itself is a special Button implemented by encapsulating the Button.

Therefore, the ImageButton class does not actually exist in the Microsoft.UI.Xaml.Controls Namespace.

Since the ImageButton is obtained by encapsulating the Button, it is necessary to modify the implementation through the Button when modifying the ImageButton.

Alec Liu.
