Automatically update selection based on frame

[cyril-schroeder-ox]

Hi all,

I am trying to solve pretty much the same problem as issue #218 - also updating the selection to only display molecules which are in contact on a frame-by-frame basis. What would it take to directly access the Pymol event signals and run a function each time I move to a new frame by accessing these signals? So far I couldn't find anything of the sort and have to manually run my function each time.

Thanks a lot in advance for your help!

Best, Cyril

Wizards can act as callbacks on various events. Example:

from pymol import cmd
from pymol.wizard import Wizard

class StateCallbackWizard(Wizard):
    def get_event_mask(self):
        return Wizard.event_mask_state
    def do_state(self, state):
        self.cmd.select("atoms_with_negative_x", "x < 0", state=state, quiet=0)

cmd.set_wizard(StateCallbackWizard())
