Setting how Kanzi Engine handles unused resources¶
When a resource is not used, Kanzi Engine keeps it in the memory until you call ResourceManager::purge. You can set how Kanzi Engine handles unused resources when you call ResourceManager::purge for each resource separately, or for the resources in the entire project.
You an also set Kanzi Engine to immediately remove from memory resources that are not in use by setting ResourceManager::setDefaultMemoryStrategy to OptimizeMemory.
Setting how Kanzi Engine handles unused resources in the entire project¶
To set for the entire project how Kanzi Engine handles unused resources when you call ResourceManager::purge, in the main menu select Project > Properties, and in the Properties set:
The Resource Keep Alive BehaviorResource Keep Alive Behavior property sets how Kanzi Engine handles all unused resources.
Allow unload if unused to remove resources when they are not in use anymore.
