VB6 StarRating-Control (cairo-Rendering)

[Schmidt]

This is an implementation, based on Vector-Drawing (with the cairo-Wrapper-Classes from vbRichClient5).
No (PNG- or other) Images were used - just plain Drawing-Commands (to gain more flexibility with regards to
the Stars Shape - and to easier allow for different Base-Colors to fill the interior of the given Star-DrawingPath).

A normal VB6-UserControl is used as the Host for these Drawings - fully transparent and alpha-aware.

The Star-Rendering will be smooth and antialiased, even when the Controls are resized
(to behave properly in DPI-aware Apps).

The MinHeight of the Control is 16-, its MaxHeight 56-Pixels.

The ScreenShot below shows, how the rendering behaves with different Sizes (and Colors).

The Value of the Control can be set also per Mouse-Interaction (Drag- or Click) - and
will (in Drag-Mode) show a darker "Hover-Overlay" (so the older Value can be seen for comparison,
until the Mouse-Button is released).

Here's the Source-Zip: StarRating2.zip
(updated with a fix for: "Allow Zero-Detection whilst clicking outside the first Star")

New version - (containing the fix above, but also a new modRC5Regfree.bas, which when included
into a Project, will ensure regfree-loading of the RC5-Main-Classes automatically - when:
- your App will run from a compiled Executable ... and
- when a \Bin\-SubFolder exists below your App.Path, which contains copies of the 3 RC5 BaseDlls
Version 3: StarRating3.zip

And here a ScreenShot:
