Class: CoordinatesDisplayLayer

CoordinatesDisplayLayer(worldWindow)

Displays the current map coordinates. A coordinates display layer cannot be shared among World Windows. Each WorldWindow if it is to have a coordinates display layer must have its own. See the MultiWindow example for guidance.

Constructor

new CoordinatesDisplayLayer(worldWindow)

Constructs a layer that displays the current map coordinates.
Parameters:
Name Type Description
worldWindow WorldWindow The WorldWindow associated with this layer. This layer may not be associated with more than one WorldWindow. Each WorldWindow must have it's own instance of this layer if each window is to have a coordinates display.

Methods

(protected) doRender(dc)

Subclass method called to display this layer. Subclasses should implement this method rather than the render method, which determines enable, pick and active altitude status and does not call this doRender method if the layer should not be displayed.
Parameters:
Name Type Description
dc DrawContext The current draw context.
Overrides:
Source:

(protected) isLayerInView(dc) → {boolean}

Indicates whether this layer is within the current view. Subclasses may override this method and when called determine whether the layer contents are visible in the current view frustum. The default implementation always returns true.
Parameters:
Name Type Description
dc DrawContext The current draw context.
Inherited From:
Source:
Returns:
true If this layer is within the current view, otherwise false.
Type
boolean

refresh()

Refreshes the data associated with this layer. The behavior of this function varies with the layer type. For image layers, it causes the images to be re-retrieved from their origin.
Inherited From:
Source:

render(dc)

Displays this layer. Subclasses should generally not override this method but should instead override the doRender method. This method calls that method after verifying that the layer is enabled, the eye point is within this layer's active altitudes and the layer is in view.
Parameters:
Name Type Description
dc DrawContext The current draw context.
