How can I get color properties of all actors?
(This might be an easy question. However I don't know the solution.)
I made an simple multi-STL files viewer using PyQt5 and VTK library.
There is rendering widget (QVTKRenderWindowInteractor) and a reset button (QPushButton).
If I click the reset button, the color of the actors (all loaded STL data) are changed to white.
Following code is the reset button click function
(It works well):
def _resetBtnClicked(self):
# reset actor colors
actorCollection = self.ren.GetActors()
actorCollection.InitTraversal()
cactor = actorCollection.GetNextActor() # first actor
while cactor != actorCollection.GetLastActor():
cactor.GetProperty().SetColor(1, 1, 1)
cactor = actorCollection.GetNextActor()
cactor.GetProperty().SetColor(1, 1, 1) # last actor
The self.ren is the vtk.vtkRenderer() and I used while roop to deal with ACTORs COLOR using .GetNextActor(), sequently.
However, I want to change the while loop to a simple code, like self.ren.GetActors().GetProperty().SetColor(1, 1, 1) if possible (this 'self.ren.GetActors().GetProperty().SetColor(1, 1, 1)' isn't existed).
If there are several function I can use instead of while roop, please let me know.

don't know the datatypes - no idea whatrenorren.getActor()is/returns - but why not use a simplerfor actor in actorCollection: actor.GetProperty().SetColor(1,1,1)? Your question might be better served if you post a Minimal, Complete, and Verifiable example
