- Linux GCC rejects QMetaType instantiation over incomplete types (static_assert(sizeof(T))); Q_DECLARE_OPAQUE_POINTER every opaque OakEngine* handle in the public headers so QList<OakEngineTask*> etc compile - Windows: gtest discovery ran the fresh exe before the DLLs were next to it; use DISCOVERY_MODE PRE_TEST on WIN32 and copy the DLLs for ctest time

|
|
* introspection, parameter access and edge editing
|
|
*
|
|
* An OakEngineNode wraps the engine's olive::Node (engine/node/node.h).
|
|
* Handles are borrowed views of nodes owned by their project (QObject
|
|
* parent chain); they become invalid when the project is freed or the node
|
|
* is removed (e.g. by undoing oakengine_project_add_node()).
|
|
*
|
|
* Parameter values cross the boundary as the small POD oak_node_value;
|
|
* which of its fields are meaningful depends on the oak_node_value_type
|
|
* (see the enum). String-typed inputs (NodeValue::k_file) do not fit the
|
|
* POD and use the dedicated oakengine_node_get/set_input_string() pair
|
|
* (buf/size convention).
|
|
*
|
|
* Every mutating call is undoable through the global undo stack, like the
|
|
* timeline editing primitives (direct non-undoable application when the
|
|
* engine is not initialized). Errors follow the family model: negative
|
|
* OAKENGINE_E_* codes, NULL handles as no-ops, and a thread-local
|
|
* human-readable reason via oakengine_node_last_error().
