# the double call is just a temporary fix for an issue I will address in a future release.
# Problem: because the signal emitted when setting a flow theme is directly connected to the according slots
# in NodeInstance as well as NodeInstance_TitleLabel, the NodeInstance's slot (which starts an animation which
# uses the title label's current and theme dependent color) could get called before the title
# label's slot has been called to reinitialize this color. This results in wrong color end points for the
# title label when activating animations.
# This is pretty nasty since I cannot think of a nice fix for this issue other that not letting the slot
# methods be called directly from the emitted signal but instead through a defined procedure like before.
# maybe this will be necessary due to scheduling issues when loading flows
# for s in self.scripts:
# s.flow.viewport().update()
