Python End of Slicing operation Looking for a smarter code

[Cuq 198]

Hello,

 

I'm sure there's a more elegant way to get the end of Slicing event. But I can't find it. Note : This code works but the use of timers is really not clean.  If you could suggest me a more elegant way to recode this little piece of code.

 

Goal : Load an STL file -> Start slicing-> Export the gcode and read it back into Cura

 

import time
from typing import cast

from cura.CuraApplication import CuraApplication
from UM.PluginRegistry import PluginRegistry
from UM.Mesh.MeshWriter import MeshWriter 
from UM.Message import Message

FileName="C:/Temp/Tube.stl"
FileGcode="C:/Temp/Tube.gcode"
	
Me = CuraApplication.getInstance()

# Me.deleteAll()
Me._openFile(FileName)

# time.sleep(1)
print("File loaded {}".format(FileName))

Me.backend.forceSlice()
Me.backend.slice()

i=0
while Me.backend._slicing:
    time.sleep(1)
    i+=1
    print("Wait ! {} s".format(i))

gcode_writer = cast(MeshWriter, PluginRegistry.getInstance().getPluginObject("GCodeWriter"))

# open wt Write and text mode
with open(str(FileGcode), "wt") as stream:
    success = gcode_writer.write(stream, None)
print("Save Gcode Ok {} !".format(success))

Me._openFile(FileGcode)

perhap's a begining of solution with  QTimer()  and  isActive() but I don't know if it's really better than 

time.sleep
