Properties

CameraX

Camera X position in tile coordinates.

Returns: Double

public double CameraX { get; set; }

CameraY

Camera Y position in tile coordinates.

Returns: Double

public double CameraY { get; set; }

ContentChild

The reconciled content child node. This is the root of the widget tree built by the tile panel widget.

Returns: Hex1bNode

public Hex1bNode? ContentChild { get; set; }

DataSource

The tile data source.

Returns: ITileDataSource

public ITileDataSource? DataSource { get; }

IsFocusable

Tile panel nodes are NOT themselves focusable - focus passes through to children.

Returns: Boolean

public override bool IsFocusable { get; }

IsFocused

Focus state exists on the content child, not the tile panel node itself.

Returns: Boolean

public override bool IsFocused { get; set; }

PointsOfInterest

Points of interest to display on the map.

Returns: IReadOnlyList<TilePointOfInterest>

public IReadOnlyList<TilePointOfInterest> PointsOfInterest { get; }

ZoomLevel

Zoom level. 0 = 1x, 1 = 2x, 2 = 4x, etc.

Returns: Int32

public int ZoomLevel { get; set; }

Methods

ArrangeCore(Rect)

Override this method to implement arranging logic for this node. The base implementation saves previous bounds, marks dirty on change, and sets bounds.

Parameters:

• rect (Rect):

protected override void ArrangeCore(Rect rect)

Dispose()

Disposes the tile cache and cancels pending background fetches.

public void Dispose()

GetChildren()

Gets the direct children of this node for structural tree traversal. Container nodes should override this to return their children.

Returns: IEnumerable<Hex1bNode>

public override IEnumerable<Hex1bNode> GetChildren()

GetFocusableNodes()

Gets all focusable nodes in this subtree (including this node if focusable).

Returns: IEnumerable<Hex1bNode>

public override IEnumerable<Hex1bNode> GetFocusableNodes()

MeasureCore(Constraints)

Override this method to implement measuring logic for this node.

Parameters:

• constraints (Constraints):

Returns: Size

protected override Size MeasureCore(Constraints constraints)

Render(Hex1bRenderContext)

Renders the node to the given context.

Parameters:

• context (Hex1bRenderContext):

public override void Render(Hex1bRenderContext context)
