WindowKey

class HPS.WindowKey : HPS.SegmentKey 

The WindowKey class is a smart pointer to a database object. Windows are special segments that are backed by a driver instance and a physical window. Some operations and attributes can only be performed or set from window keys. The WindowKey class itself is a base class for more specific window types (application windows, off-screen windows, stand-alone windows).

Subclassed by HPS.ApplicationWindowKey, HPS.OffScreenWindowKey, HPS.StandAloneWindowKey

void Update (): Performs a default update in this window, redrawing and refreshing the display.

void Update (HPS.UpdateOptionsKit in_kit)

Performs an update in this window, redrawing and refreshing the display using the options in the UpdateOptionsKit.

Param in_kit:	Allows the user to control how thorough an update should be.

void Update (HPS.Window.UpdateType in_type)

Performs an update in this window within the specified amount of time, redrawing and refreshing the display based on the Window.UpdateType value. Key behavioral notes regarding a timed-update:

Geometry deferral/omission
- View-dependent shadows will not be drawn (view-independent shadows will be drawn.)
- Transparent geometry will be deferred and processed after the rest of the scene.
- If static tree + lmv is enabled, text and lines will be deferred and drawn after opaque facetted geometry
Non-incremental rendering modes/attributes
- A timed update requires Visualize to interrupt the rendering process. However, certain types of rendering modes/attributes cannot be interrupted because they are ‘non-incremental’. - If your application wishes to use such modes/attributes alongside fixed-framerate, it will need to make a decision about whether Fixed-framerate is preferred. They include: - HiddenLine and FastHiddenLine rendering algorithms
  - Transparency that is drawn using ‘depth peeling’. (All depth-peeled transparent geometry will be processed once it is started.)

void Update (HPS.Window.UpdateType in_type, double in_time_limit)

Performs an update in this window within the specified amount of time, redrawing and refreshing the display based on the Window.UpdateType value. Key behavioral notes regarding a timed-update:

Geometry deferral/omission
- View-dependent shadows will not be drawn (view-independent shadows will be drawn.)
- Transparent geometry will be deferred and processed after the rest of the scene.
- If static tree + lmv is enabled, text and lines will be deferred and drawn after opaque facetted geometry
Non-incremental rendering modes/attributes
- A timed update requires Visualize to interrupt the rendering process. However, certain types of rendering modes/attributes cannot be interrupted because they are ‘non-incremental’. - If your application wishes to use such modes/attributes alongside fixed-framerate, it will need to make a decision about whether Fixed-framerate is preferred. They include: - HiddenLine and FastHiddenLine rendering algorithms
  - Transparency that is drawn using ‘depth peeling’. (All depth-peeled transparent geometry will be processed once it is started.)

Param in_time_limit:
	Specifies the desired maximum time this update should take.

HPS.UpdateNotifier UpdateWithNotifier (HPS.UpdateOptionsKit in_kit)

Performs a default update in this window, redrawing and refreshing the display.

Return:	A UpdateNotifier object that can be used to find out information about the update.

HPS.UpdateNotifier UpdateWithNotifier (HPS.Window.UpdateType in_type)

Performs an update in this window, redrawing and refreshing the display.

Param in_type:	Allows the user to control how thorough an update should be.
Return:	A UpdateNotifier object that can be used to find out information about the update.

HPS.UpdateNotifier UpdateWithNotifier (HPS.Window.UpdateType in_type, double in_time_limit)

Param in_time_limit:
Param in_type:	Allows the user to control how thorough an update should be.
	Specifies a maximum time this update should take.
Return:	A UpdateNotifier object that can be used to find out information about the update.

WindowKey (): An uninitialized key refers to no database object and Type() will return Type.None.

WindowKey (HPS.Key in_key): Shares a reference to a database object referred to by in_that. If the key assignment is invalid, this key will revert to an uninitialized state.
