With the FluentApi.dll standalone API, you can experiment with Fluent effects in your applications without using FMXInno.
It functions similarly to FMXInno but comes with some limitations.

Here are examples of how to use FluentApi.dll in:

1. InnoSetup
2. VCL - Delphi
3. FMX - Delphi

NOTE:
1. Change the form fill color to Null.
2. Enable DoubleBuffered for InnoSetup / VCL.


>> Double Buffered:

For Inno/VCL, it's important to enable double buffering for forms before using fluent effects.
However, the original version of InnoSetup doesn't support double buffering natively but requires the enhanced edition.
Therefore, I have provided you with two DLLs that enable double buffering for forms in InnoSetup.

If you know a better way to achieve this, let me know, as in this case, 'WS_EX_COMPOSITED' does not work.

IS5Extra.dll ==> for InnoSetup 5.x
IS6Extra.dll ==> for InnoSetup 6.x

In simple terms, if you change the system mode (dark/light) while the app is running,
the app will automatically change its mode (dark/light) to match the system mode.
However, this feature does not work for custom-colored fluent forms and is supported only on Win10 and Win11.
