dataRetain

Set retain token for this key (id+name). null means remove retain token.

Can be called from any thread.

If called from non-GUI thread or outside Window.begin/Window.end, you must pass a pointer to the Window you want to add the value to.

While a key has retain dvui will not free its value. To free it you must call either this with null, dataRemove, or retainClear.
