/*
|
||
|
* Element Properties
|
||
|
*
|
||
|
* Element provides default behavior for Get/SetValue based on the flags used in PropertyInfo.
|
||
|
* The Flags also define what indicies are available during property operations.
|
||
|
*
|
||
|
* Get/SetValue cannot be overridden. Rather, a default implemention is supplied for GetValue's
|
||
|
* on all properties. By default, Get's on the Specified and Computed index are handled by a
|
||
|
* built-in Value Expression (VE) while Get's on Local query a local store (see below for exact
|
||
|
* default behavior). However, various system properties override this default behavior with
|
||
|
* different unchangable Value Expressions (implicit VEs) in the Local and Computed indicies.
|
||
|
*
|
||
|
* End users will use Normal properties and may occasionally use LocalOnly properties. Although
|
||
|
* available to derived classes, TriLevel property functionaly is only useful by the system.
|
||
|
*
|
||
|
* All property value must be available generically through GetValue.
|
||
|
*
|
||
|
* Flags supported (default behavior):
|
||
|
*
|
||
|
* "LocalOnly"
|
||
|
* Indicies: Local
|
||
|
* Get: Retrieve local value from Element. If none is set, 'Unset' returned.
|
||
|
* Set: Stores value locally on the Element.
|
||
|
* Dependents: None
|
||
|
* Modifiers: Readonly: Disallow Set
|
||
|
*
|
||
|
* "Normal"
|
||
|
* Indicies: Local, Specified (implicit VE)
|
||
|
* Get: Local: Retrieve local value from Element. If none is set, 'Unset' returned.
|
||
|
* Specified: Does a Get on the Local value. If 'Unset', return Property Sheet value
|
||
|
* if Cascade modifier is set. If 'Unset', return parent's value if Inherit
|
||
|
* modifier is set. If 'Unset' return property's Default value.
|
||
|
* Automatically evaulate value expressions before return.
|
||
|
* Set: Local: Stores value locally on the Element.
|
||
|
* Specified: Unsupported.
|
||
|
* Dependents: Specified is dependent on Local.
|
||
|
* Modifiers: Readonly: Disallow Set for Local.
|
||
|
* Cascade: Used with Specified Get (see Get description).
|
||
|
* Inherit: Used with Specified Get (see Get description).
|
||
|
*
|
||
|
* "TriLevel"
|
||
|
* Indicies: Local, Specified (implicit VE), Computed (implicit VE)
|
||
|
* Get: Local: Retrieve local value from Element. If none is set, 'Unset' returned.
|
||
|
* Specified: Does a Get on the Local value. If 'Unset', return Property Sheet value
|
||
|
* if Cascade modifier is set. If 'Unset', return parent's value if Inherit
|
||
|
* modifier is set. If 'Unset' return property's Default value.
|
||
|
* Automatically evaulate value expressions before return.
|
||
|
* Computed: Does a get of the Specified value.
|
||
|
* Set: Local: Stores value locally on the Element.
|
||
|
* Specified: Unsupported.
|
||
|
* Computed: Unsupported.
|
||
|
* Dependents: Computed is dependent on Specified. Specified is dependent on Local.
|
||
|
* Modifiers: Readonly: Disallow Set for Local.
|
||
|
* Cascade: Used with Specified Get (see Get description).
|
||
|
* Inherit: Used with Specified Get (see Get description).
|
||
|
*
|
||
|
* SetValue must always be used by derived classes. However, SetValue is sometimes bypassed and
|
||
|
* Pre/PostSourceChange is called directly in the case of LocalOnly properties that are ReadOnly
|
||
|
* and are cached directly on the Element (optimization). All other ReadOnly sets use
|
||
|
* _SetValue since generic storage (of Values) is used. SetValue is used in all other cases.
|
||
|
*
|
||
|
* For ReadOnly values, if storing the value is cheap (i.e. bools) and interit and style sheet
|
||
|
* functionality is not required, it is best to not use generic storage (_SetValue). Rather,
|
||
|
* write the value directly and call Pre/PostSourceChange directly ("LocalOnly property).
|
||
|
* Otherwise, if a ReadOnly value requires inheritance and/or sheet lookups, or the value is
|
||
|
* seldom different than a default value, use _SetValue (generic storage, "Normal" property).
|
||
|
*
|
||
|
* For Normal/ReadOnly, use SetValue, For LocalOnly/ReadOnly, use _SetValue,
|
||
|
* For internal LocalOnly/ReadOnly, set and store manually (no generic storage)
|
||
|
*
|
||
|
* All property values must be settable generically via SetValue except ReadOnly properties.
|
||
|
* Any "LocalOnly" property that doesn't use generic storage must initialize their members
|
||
|
* at construction to the property's default value. "Normal" properties will choose the
|
||
|
* default value automatically when queried. All derived classes (external) will use "Normal"
|
||
|
* properties.
|
||
|
*
|
||
|
* SetValue only accepts the PI_Local index. ReadOnly sets do not fire OnPropertyChanging.
|
||
|
* All value sets must result in a PreSourceChange, followed by the store update (in which GetValue
|
||
|
* will retrieve values from), followed by a PostSourceChange. OnPropertyChange and old value
|
||
|
* compare are optional.
|
||
|
*
|
||
|
* Set values are updated immediately (i.e. an immediate GetValue after will produce the updated
|
||
|
* result). Location and Extent are updated after the defer cycle ends (EndDefer, SetValues are internal).
|

/*
|
||
|
* Element Multithreading
|
||
|
*
|
||
|
* Elements have context affinity. A single thread is allowed per context. This thread
|
||
|
* is owned by the context. Only that thread may be allowed to access objects in its
|
||
|
* context. This requirement is not enforced in this library. The caller application
|
||
|
* must ensure access to objects in a context happens via the owned thread.
|
||
|
*
|
||
|
* A Proxy class is provided to invoke methods on objects from an out-of-context thread.
|
||
|
*
|
||
|
* The library supports multiple instances in the same process. This would happen by
|
||
|
* linking the library to multiple process modules. The only restriction is a thread
|
||
|
* must access a set of objects consistantly with the same instance of the library code.

/*
|
||
|
* Error Reporting
|
||
|
*
|
||
|
* Conditions that would affect the stability of DirectUI are reported. Some conditions are
|
||
|
* only reported in Debug builds, and other in both Release and Debug
|
||
|
*
|
||
|
* Debug time reporting:
|
||
|
* Erroneous states are reported in Debug (checked) builds. An erroneous state arises
|
||
|
* when a programming error is found or when invalid arguments are passed to a method.
|
||
|
* Erroneous states cause raising of asserts
|
||
|
*
|
||
|
* Release time reporting:
|
||
|
* Abnormal states (such as out of memory or resources) that result in a serious condition
|
||
|
* (crash or very irregular state) are reported via HRESULTs. Any DUI API that can fail due to
|
||
|
* these types of abnormal states returns an HRESULT. If a method fails, it will recover.
|
||
|
* Some methods (such as object creation methods) will recover by freeing any memory or
|
||
|
* resources allocated within that method (resulting of a complete undo of all the work it
|
||
|
* accomplished up to the point of the failure). Other methods (such as rendering and the defer
|
||
|
* cycle) will do as much work as possible. Upon a failure, they will return an 'incomplete'
|
||
|
* error, however, they would have not completed. Failures do not result in crashes or irregular
|
||
|
* state. Failures are ignored in callbacks
