You could grab the reference to the main progress bar and connect to its
signal:
import maya.OpenMayaUI as mui
from PySide import QtGuiimport shiboken
ptr = mui.MQtUtil.mainWindow()
win = shiboken.wrapInstance(long(ptr), QtGui.QWidget)
prog = win.findChild(QtGui.QProgressBar)print prog.objectName()
def print_progress(val):
print "Progress!", val
prog.valueChanged.connect(print_progress)
But be careful not to do anything big in your slot since it will hold up
the app :-)
Using the thread doesn't really help here since it will still place the
call into the main event loop and as soon as your file process starts, none
of your other code will get called. So you kind of need the slot connection
to the progress bar since it is being used as part of that call. However,
you could feed the progress to something else running in a thread to handle
stuff that needs to do more work.
