What I was saying was that if you are going to use the fileDialog approach,
as you did, and you see that it returns an error, you would have to make
sure that you take a look at the API documentation to confirm that you are
using it properly. In this case, the fileDialog returns an array of
strings, and you are passing that array to the file() command, which only
takes a string. So you end up with an error.
Because you are using a fileDialog command that allows the user to choose
one existing file, you will need first check the filename variable to make
sure it is set to something and that the user did not cancel the dialog.
Because the people that designed the Maya cmds API love and value
consistency, you will notice that if the dialog is canceled you get back a
None instead of an empty list. Your check would be something like this:
fileList = cmds.fileDialog2(fileMode=1, fileFilter=multipleFilters,
dialogStyle=2)if not fileList:
# return or print something or bail out early
filename = fileList[0]
cmds.file(filename, i=True)
If you are allowing multiple files:
fileList = cmds.fileDialog2(fileMode=4, fileFilter=multipleFilters,
dialogStyle=2)if not fileList:
# return or print something or bail out early
for filename in fileList:
cmds.file(filename, i=True)
At this point, you have control over knowing which file is being imported
and having the opportunity of doing pre/post
