Properties exposed to reflection are automatically visible in the property grid. Users can extend the property grid to show data not known to the reflection system by implementing PropertyGrid::IPlugin.
There are two ways to add functionality to the property grid:
void IPlugin::onGUI(PropertyGrid& grid, Span<const EntityRef> entities, ComponentType cmp_type, const TextFilter& filter, WorldEditor& editor);
IPlugin::onGUI is called at the end of every component in the property grid.
While the reflection system does recognize blob properties, it treats them as an opaque block of data. The system doesn’t attempt to understand or display their internal structure, leaving it entirely up to the plugin to interpret and render the content meaningfully. This is used in the Lua plugin to display properties defined in Lua scripts.
void IPlugin::blobGUI(PropertyGrid& grid, Span<const EntityRef> entities, ComponentType cmp_type, u32 array_index, const TextFilter& filter, WorldEditor& editor);
IPlugin::blobGUI is called for every blob property in every component in the property grid.
