All Implemented Interfaces:
  `MapSurface, Animation, Editable, StyleListener, Iterable<Component>`

public class MapView extends Container implements MapSurface

A pure-vector map component: it renders entirely through the Codename One `Graphics` API (the built-in `VectorMapEngine`) and never embeds a native peer, so it composes cleanly with the rest of the UI -- dialogs, lists and overlays draw over it without the clipping limitations of a native view.

`MapView` works identically on every platform including the simulator and the web. By default it shows the free, keyless OpenFreeMap vector basemap (real OpenStreetMap data) so it renders real maps with zero configuration and no API key; point it at any other `TileSource` (a keyed MVT endpoint, a raster source such as `RasterTileSource.openStreetMap()`, or a bundled offline tileset) as needed. For a native-rendered map (Apple MapKit, Google Maps, ...) use `NativeMap`, which falls back to this component when no native provider is wired in.

  - ### MapView

    public MapView()
    Creates a map showing the free, keyless OpenFreeMap vector basemap (real OpenStreetMap data) centered on the equator at a low zoom.

  - ### MapView

    public MapView(TileSource source)
    Creates a map backed by `source` with the default light style.

  - ### MapView

    public MapView(TileSource source, MapStyle style)
    Creates a map backed by `source` and styled by `style` (the style is only consulted for vector sources).

- ## Method Details

  - ### isLoadingTiles

    public boolean isLoadingTiles()
    Whether the vector engine still has tiles in flight for the current view. Useful to defer a screenshot (or hide a spinner) until the basemap has finished loading. Always false for a native-provider-backed surface, which loads its own tiles outside the engine's knowledge.

  - ### isMapReady

    public boolean isMapReady()

  - ### asComponent

    public Component asComponent()
    This surface as a Codename One `Component` for layout purposes.
    Specified by:
      `asComponent` in interface `MapSurface`

  - ### paintBackground

    protected void paintBackground(Graphics g)
    Description copied from class: `Component`

    This method paints the Component background, it should be overriden by subclasses to perform custom background drawing.

    ###### Parameters

    - `g`: the component graphics
    Overrides:
      `paintBackground` in class `Component`

  - ### pointerPressed

    public void pointerPressed(int x, int y)

    If this Component is focused, the pointer pressed event will call this method

    ###### Parameters

    - `x`: the pointer x coordinate

    - `y`: the pointer y coordinate

    Overrides:
      `pointerPressed` in class `Container`

  - ### mouseWheel

    protected boolean mouseWheel(WheelEvent ev)

    Handles a scroll wheel or trackpad scroll over this component, before its listeners and before anything above it in the hierarchy.

    A component that moves its own content -- an editor that scrolls itself, a viewer that pans -- implements this. Everything else leaves it alone and the wheel scrolls the nearest scrollable ancestor, which is what a wheel means.

    This exists because a wheel used to arrive as a synthetic press, drag and release played into the component tree: a component that wanted the wheel got it by handling pointer events, and so did every component that did not want it. The events are gone and this is what replaces them, for the few components that have something of their own to move.

    ###### Parameters

    - `ev`: the wheel event, carrying the scroll deltas in display pixels

    ###### Returns

    true when this component handled the wheel and nothing else should act on it

    A wheel pans the camera, and tells the listeners about it -- which is the half a synthetic drag could never deliver, because the gesture it emulated had no end that meant "the pan is finished".

    Overrides:
      `mouseWheel` in class `Component`

  - ### pointerDragged

    public void pointerDragged(int x, int y)

    If this Component is focused, the pointer dragged event will call this method

    ###### Parameters

    - `x`: the pointer x coordinate

    - `y`: the pointer y coordinate

    Overrides:
      `pointerDragged` in class `Component`

  - ### pointerReleased

    public void pointerReleased(int x, int y)

    If this Component is focused, the pointer released event will call this method

    ###### Parameters

    - `x`: the pointer x coordinate

    - `y`: the pointer y coordinate

    Overrides:
      `pointerReleased` in class `Component`

  - ### longPointerPress

    public void longPointerPress(int x, int y)
    If this Component is focused this method is invoked when the user presses and holds the pointer on the Component
    Overrides:
      `longPointerPress` in class `Component`

  - ### pinch

    protected boolean pinch(float scale)
    Description copied from class: `Component`

    Invoked by subclasses interested in handling pinch to zoom events, if true is returned other drag events will not be broadcast

    ###### Parameters

    - `scale`: @param scale the scaling of the pinch operation a number larger than 1 means scaling up and smaller than 1 means scaling down. It is recommended that code would threshold the number (so a change between 1.0 and 1.02 shouldn't necessarily trigger zoom). Notice that this number is relevant to current zoom levels and unaware of them so you should also enforce limits of maximum/minimum zoom levels.

    ###### Returns

    false by default

    Overrides:
      `pinch` in class `Component`

  - ### calcPreferredSize

    protected Dimension calcPreferredSize()
    Description copied from class: `Container`

    Calculates the preferred size based on component content. This method is invoked lazily by getPreferred size.

    ###### Returns

    the calculated preferred size based on component content

    Overrides:
      `calcPreferredSize` in class `Container`
