How to prevent MultiView opacity from affecting children components texts in Delphi?

I'm using MultiView with some TButton buttons in Firemonkey. The multiView is opaque at 0.5 and this causes the buttons to also be opaque.

QUESTION: Is there a way to prevent MultiView opacity from affecting the button texts? That is, the text of the buttons would continue with bright colors, but the "body" of the buttons would be opaque. I've seen some applications with this visual feature, but I do not know what components were used for that purpose ...

Solution

Instead of the TMultiView, use a TRectangle as basis for the menu. Set its Align to left and the Fill.Color to $7FFFFFFF. The two first hex digits (7F) define the alpha channel (translucency), the rest of the hex digits (FFFFFF), define the RGB colors. This allows you to leave the Opacity at one, but still having the translucent effect. This is not possible with the TMultiView control.

For each item, use a TLayout, with a TImage and a TText and any separator lines you like. Use normal Align properties to setup the items.

Finally, set HitTest = True for the TLayout and HitTest = False for the TImage and TText controls. This is to enable mouse clicks or taps.

Below is my test, both as .fmx content (image data removed) and a snapshot.

  object Rectangle1: TRectangle
    Align = Left
    Fill.Color = x7FFFFFFF
    Size.Width = 200.000000000000000000

    Size.PlatformDefault = False
    object Layout1: TLayout
      Align = Top
      HitTest = True
      Size.Width = 200.000000000000000000
      Size.Height = 50.000000000000000000
      Size.PlatformDefault = False
      TabOrder = 0
      object Image1: TImage
        MultiResBitmap.Height = 128
        MultiResBitmap.Width = 128
        MultiResBitmap = <
          item
            Width = 128
            Height = 128
            PNG = {}
