struct SizeChangeHintEvent

Defined at line 3006 of file fidling/gen/sdk/fidl/fuchsia.ui.gfx/fuchsia.ui.gfx/cpp/fidl/fuchsia.ui.gfx/cpp/wire_types.h

Delivered in response to a size change hint from a parent node

(SendSizeChangeHintCmd).

This event is delivered when the following conditions are true:

- The node has `kSizeChangeEventMask` set to an enabled state.

- A parent node has sent a SendSizeChangeHintCmd.

Subscribe to this event to receive information about how large textures you

will need in the near future for your nodes. The canonical use case is to

pre-allocate memory to avoid repeated re-allocations.
