These controls have been created to support proper z-order with other "native" controls supplied with Delphi, such as TMapView and TWebBrowser, i.e. they can overlay the other native controls
Note that at present, most of the controls will function only on Android and iOS, however the controls are rendered in the designer close to what they will look like on the target platform.
Simply open the KastriFMX.dproj project in the folder under the Packages folder that corresponds to the major version number of Delphi that you have (e.g. Packages\D104 for Delphi 10.4.x) and Compile and Install. The components will appear in the Kastri FMX section on the Component Pallette
A very basic demo is in the Demos\NativeControls folder.
TNativeSlider is implemented as SeekBar on Android (with the added bonus of being able to use it vertically as well as horizontal), and as a UISlider on iOS
NOTE: It was necessary to create a descendant of the Java class (in order to implement a vertical SeekBar), so you will need to add dw-kastri-base.jar to the Libraries node under the Android platform in Project Manager in your project
TNativeButton is implemented as Button on Android, and as UIButton on iOS.
At present, TNativeButton provides only very basic support, e.g. the various states, titles and image support for UIButton are yet to be supported.
TNativeEllipse is like TEllipse in FMX
Both TNativeRectangle and TNativeEllipse use ImageView and GradientDrawable on Android, and CAShapeLayer and UIBezierPath on iOS for rendering the shape
The Stroke property has very basic support - only Color, Kind (Solid or None) and Thickness are currently supported
TNativeImage is implemented as ImageView on Android and UIImageView on iOS.
It has a Text property that can serve as a caption that overlays the image.
TNativeRectangle is like TRectangle in FMX. At present, on iOS rounded corners are not supported (however this is planned to be supported in the future).
