25 * @brief These macros are used internally by the property macros.
26 * Use the the property macros in the section below this one (without the _INTERNAL postfix) when defining properties.
27 * These internal macros exist as to perform the compile-time check on the enumeration order, the __COUNTER__ macro is used twice.
28 * Using it twice within the same macro would result in two different values.

42 * @brief These macros are used to define properties for implementations of CustomActor.
44 * These macros should be used when defining devel properties
45 * They provide the following benefits:
46 * - A standard and consistent way to define properties.
47 * - Concise definition promotes readability, especially with large numbers of properties.
48 * - Provides a built-in compile-time check. This checks the order of the properties within the enumeration match the order of the property macros. Note: This check is not performed for animatable properties.
49 * - Enforces how properties are enumerated in the object handles header file.
51 * Note: The compile-type check will produce the following message on failure:
52 * error: invalid application of 'sizeof' to incomplete type 'Dali::CompileTimeAssertBool<false>'
54 * Macro usage example:
56 * Within the your object's implementation cpp:
58 * #include <dali/public-api/object/devel-property-helper.h>
60 * DALI_TYPE_REGISTRATION_BEGIN( MyApp::MyCustomActor, Dali::CustomActor, Create )
61 * DALI_DEVEL_PROPERTY_REGISTRATION( MyApp, MyCustomActor, "myProperty", INTEGER, MY_DEVEL_PROPERTY )
62 * DALI_TYPE_REGISTRATION_END()
65 * Within your handle's header:
68 * #include <dali/public-api/common/dali-common.h>
71 * ///< @brief The start and end property ranges for this control.
74 * PROPERTY_START_INDEX = Dali::PROPERTY_REGISTRATION_START_INDEX,
75 * PROPERTY_END_INDEX = PROPERTY_START_INDEX + 1000
78 * ///< @brief An enumeration of properties belonging to the Button class.
83 * MY_PROPERTY = PROPERTY_START_INDEX ///< @brief name "myProperty", type Integer
88 * Using these macros have certain prerequisites on how the property enumeration is defined.
89 * Please see the Programming Guide (within the generated Doxygen) for full details.
