Ok, when I change the trigger from pressCommand to releaseCommand it works
for me.
The reason I think, is because when you press you put Maya in a suspended
mode. Awaiting a release. During the release it would resume normal duties
like updating the GUI and viewport. But, because you create a reference
while being pressed, you prevent Maya from detecting a release. As though
you were erasing its memory of anything being pressed. That could explain
why you would have to forcefully refresh Maya after exiting the context.
Full example.
import types
from maya import cmds
def func_test():
nodes = cmds.file("scenes/temp.ma", reference=True, returnNewNodes=True)
cmds.select(nodes)
class PickerContext(object):
CONTEXT_NAME = "PickerContext"
def __init__(self, func, **kwargs):
self.__undo_mode = kwargs.get("undoMode", "step")
self.__projection = kwargs.get("projection", "viewPlane")
self.__space = kwargs.get("space", "screen")
self.__cursor = kwargs.get("cursor", "crossHair")
self.__selected_nodes = list()
if not isinstance(func, (types.FunctionType, types.ClassType,
types.MethodType)):
raise BaseException("Invalid argument given !!!\n\tGive a
function or class with matrix for argument...")
self.func = func
def build(self):
if cmds.draggerContext(self.CONTEXT_NAME, exists=True):
cmds.setToolTo("selectSuperContext")
cmds.selectMode(object=True)
cmds.deleteUI("PickerContext")
cmds.draggerContext(
self.CONTEXT_NAME,
releaseCommand=self.on_press,
name=self.CONTEXT_NAME,
)
def launch(self):
self.build()
cmds.setToolTo(self.CONTEXT_NAME)
def on_press(self):
self.func()
# Create a reference
cmds.file(new=True, force=True)
cmds.polyCube()
cmds.file(rename="temp.ma")
cmds.file(save=True, force=True)
cmds.file(new=True, force=True)
# Pick
cmds.sphere(radius=0.5)
picker_ctx = PickerContext(func_test)
picker_ctx.launch()
