sealed class TerrainViewWidget implements IEventListener
  extends Widget

Configuration

ToConfig

Returns the configuration value that describes this object.

public override method ToConfig ()
type ConfigValue
returns [not-null] The configuration value.
overrides Widget.ToConfig

Remarks:

All configurable objects need to implement this interface. For simple types, it is preferable to delegate to ToValue.

The returned value may be of type Invalid, which means that this object in its current state cannot be described with the configuration API.

Before returning the resulting configuration value, Cache must be called on it, passing this IConfigurable object as parameter.

public property ActualBounds { get }
type Box2I
value The actual pixel bounds or Empty.
inherited Widget.ActualBounds

Public / Constructors

TerrainViewWidget

Creates a new instance of TerrainViewWidget.

public constructor TerrainViewWidget ()

Public / Methods

AcquireTry

Acquires a strong reference to this disposable object.

[OwnerReturn, ThreadSafe]
public method AcquireTry ()
type IDisposable
returns this if a new strong reference has been acquired, null if this object is already being disposed.
inherited Disposable.AcquireTry

Remarks:

The object will not be actually disposed by calls to Dispose when there is at least one strong reference left. Code that calls the AcquireTry method is responsible for calling the Dispose method accordingly.

This method is not intended to be used in performance-critical code. It should only be used to high-level resource management.

AddUserInterface

Adds a GUI panel to this widget.

public method AddUserInterface (WidgetSlot slot, [Owner] Panel panel)
params slot The widget GUI slot where the given GUI panel will be put.
  panel [not-null] The GUI panel to add.
inherited Widget.AddUserInterface

ConsumeInput

Consumes the given user input event.

public method ConsumeInput (InputEvent inputEvent)
type bool
params inputEvent The user input event.
returns true if the input event has been consumed, false if not.
inherited Widget.ConsumeInput

Remarks:

Input events are provided to an IInputConsumer object only if it has the input focus (see FocusGained and FocusLost). Mouse events are provided when the mouse cursor is inside of the input bounds (MouseEnter and MouseLeave). The Closing event can be provided at any time.

  1. FocusGained: gained input focus
  2. Keyboard events:
  3. Mouse events:
    1. MouseEnter
    2. Mouse events:
    3. MouseLeave
  4. FocusLost: lost input focus
  5. Closing: user request to shut down

CreateOwnTerrain

Discard the current terrain view (see Terrain) and creates own TerrainBuffer, TerrainMesh and Terrain objects, based on the given options.

public method CreateOwnTerrain ([Owner] MeshOptions meshOptions, [Owner] PyramidFileCache cache = null, [Owner] IHeightmap gravity = null)
type TerrainMesh
params meshOptions [not-null] Options to use for creating the TerrainMesh object.
  cache The pyramid file cache to use or null for none. Defaults to null.
  gravity Optional heightmap that stores gravity-related offsets from the ellipsoid surface (see Gravity). Defaults to null.
returns [not-null] The TerrainMesh object, owned by this widget.

Dispose

Releases all resources held by this object if there are no more strong references to it, decrements the reference counter by one otherwise.

[Dispose, OwnerThis, ThreadSafe]
public method Dispose ()
inherited Disposable.Dispose

Remarks:

The Dispose method silently returns if the object has already been disposed.

GraphicsAttach

Attaches this component to the given Graphics context.

public override method GraphicsAttach (Graphics graphics)
params graphics [not-null] The graphics context.
overrides Widget.GraphicsAttach

Remarks:

All graphics-related resources should be created here.

GraphicsDetach

Detaches this user interface component from its Graphics context.

public override method GraphicsDetach ()
overrides Widget.GraphicsDetach

Remarks:

All graphics-related resources should be disposed here.

GraphicsResize

The screen size has changed.

public method GraphicsResize (Vec2I screenSize)
params screenSize The new screen size, in pixels.
inherited Widget.GraphicsResize

Remarks:

The given screen size is equal to the value of ScreenSize of the Graphics object that has been passed to GraphicsAttach earlier.

Initialize

Initializes the object, if necessary

public method Initialize ()
inherited Initializable.Initialize

Remarks:

The Initialize method returns silently if the object is already in the state Initialized.

InputAttach

Attaches this input consumer to the given input state object.

public virtual method InputAttach (IInputState input)
params input [not-null] The input state object.
inherited Widget.InputAttach

Remarks:

The input state object provides a snapshot of the input keys and buttons. It should not be used to detect up/down/click events.

InputDetach

Detached this input consumer from its input state object.

public virtual method InputDetach ()
inherited Widget.InputDetach

JsonDeserialize

Restores the object state from the given JSON value.

public override method JsonDeserialize (JsonValue value)
params value [not-null] The input JSON value.
overrides Widget.JsonDeserialize

Remarks:

Implementations of this method must be able to consume malformed JSON values, without corrupting the object state.

JsonSerialize

Serializes the object state to an JSON value.

public override method JsonSerialize (JsonValue value)
params value [not-null] The output JSON value.
overrides Widget.JsonSerialize

NotifyEvent

The event has been triggered.

public method NotifyEvent (object argument)
params argument The event argument.
implements IEventListener.NotifyEvent

Render

Performs rendering.

public override method Render ()
overrides Widget.Render

Remarks:

Implementing methods must not assume that any specific render state is in place when being called. Instead, the implementing method is responsible for setting up all state that is required for rendering.

Usually, implementing classes receive their current graphics context directly or indirectly from GraphicsContextAttach or GraphicsAttach.

In order to maximize parallelism between the CPU and GPU, only actual rendering (using the current graphics context) should be performed here. All other preparation resp. setup should be done in RenderPrepare instead.

See also:

IApplication.GraphicsContextAttach
IGraphicsComponent.GraphicsAttach

Render2D

Performs 2D rendering.

public override method Render2D (Graphics g)
params g [not-null] The graphics object to use.
overrides Widget.Render2D

Remarks:

When this method is called, the given Graphics object has already been initialized for 2D rendering:

Usually, Render2D is called from within Render.

RenderPrepare

Prepares rendering.

public override method RenderPrepare ()
overrides Widget.RenderPrepare

Remarks:

This method is called before Render, when the graphics context has not yet begun to render the scene.

All setup work that does not require a graphics context (e.g. matrix computation, per-frame visibility determination) should be done here. This can help to maximize parallelism between the CPU and the GPU.

Screenshot

Takes a screenshot the next time this widget is rendered.

public virtual method Screenshot (WidgetScreenshotDelegate result)
params result [not-null] The screenshot pixels will be passed to this delegate.
inherited Widget.Screenshot

UpdateFrameTime

This method is called once per application frame.

public override method UpdateFrameTime (float32 time)
type bool
params time [>0] The amount of time that has elapsed since the last frame, in seconds.
returns true if the object needs to be presented again, false if the current presentation is still valid.
overrides Widget.UpdateFrameTime

UpdateGui

public override method UpdateGui ()
overrides Widget.UpdateGui
