sync

Compares all read- and write-able properties from src and dest that have all flags set.

Differing values are then copied from src to dest. If flags is 0, all differing read/write properties.

Properties marked as "construct-only" are not touched.

If the two objects are not of the same type, only properties that exist in both object classes and are of the same value_type are synchronized

Parameters:

src	a Object
dest	another Object
flags	a mask of GParamFlags

Returns:

true if dest was modified, false otherwise
