Design by avoidance of particularly tricky stuff ;-) Im pretty sure old old versions of Clutter used to take scale transforms at least into account. > the get_size() functions always return untransformed > sizes; the get_abs_size () return size as they end up on the screen, so > get_abs_size () should return the absolute size of the group as > projected on screen, but I suspect it might be broken, just projecting > the group bounding box calculated by query_coords(), which is not the > actual bounding box of the group if the actors in it are transformed. > > We probably need another function here alongside the get_size() and > get_abs_size () that will calculate the actual bounding box of the group > taking into account the transformations applied to the actors. > As I understand it; - get_size() should return the 'true' bounding box of its children by calling abs_size|get_vertices on each child. - Note its only for its children *not* itself - i.e get_size() would return the same value for a group in transformed and untransformed cases. - We have a catch22 in that get_abs size will take into account the size of all parents, but this is fixed by having a get_abs_size_in_respect_to_a_specific_parent kind of addition (hopefully better naming). If we do this, we should probably add a fast path to abs_size for untransformed actor case. Shoot me now if Im wrong on the above. == Matthew -- To unsubscribe send a mail to [EMAIL PROTECTED]
