Bug? setActiveNode(n) fails to make n the action target

Hi

yes, “bug”
:frowning:

The Document.waitForDone() doesn’t work properly and when working with triggered action results are not really good…

Here a modified version of script:

from krita import *
from PyQt5.Qt import *

def sleep(value):
    loop = QEventLoop()
    QTimer.singleShot(value, loop.quit)
    loop.exec()

inst = Krita.instance()
doc = inst.createDocument(60, 40, "TestDoc", "RGBA", "U8", "", 100.0)
inst.activeWindow().addView(doc)
newLayer = doc.createNode("PaintLayer", "paintlayer")
doc.rootNode().addChildNode(newLayer, None)
newLayer.enableAnimation()
doc.setActiveNode(newLayer)
doc.refreshProjection()
doc.setCurrentTime(0)
doc.waitForDone()
sleep(500)
Krita.instance().action('add_blank_frame').trigger()

def printNodes(n, indent = 0):
    print(4*indent*' ' + n.name() + ': animated=' + str(n.animated()))
    for c in n.childNodes():
        printNodes(c, indent+1)
printNodes(doc.rootNode())

I use a sleep() with a duration long enough to be sure that action has been triggered (on my computer for this action, I need to wait 500ms)

You can take a look on this topic too:

I show examples to create animated document, and the one using triggered action and waitForDone() is (currently) clearly not a solution…
