In the documentation for fileDialog2 (http://download.autodesk.com/us/maya/2011help/pymel/generated/functions/pymel.core.system/pymel.core.system.fileDialog2.html), it says acceptMode (am) can be set to 0 or 1 to tell it if it should be opening or saving images.
However, upon setting this to 0 or 1, nothing actually happens and
None is returned, and just leaving it empty will result in save dialog box. I'm currently using fileDialog to get around the problem, but it's an earlier version without as much functionality, and when one newer function should cover both, it seems pointless having to use an old one at the same time.
Here's a quick example of what to do:
import pymel.core as pm pm.fileDialog2() #brings up a save file window pm.fileDialog2( am = 1 ) pm.fileDialog2( acceptMode = 0 ) #nothing happens
help(pm.fileDialog2) just comes up with help for
list depending on if a file is selected or not.
