Hi Victor,
If you want that sort of customization, I think you'll be better off
building your own EvalString + PythonButton combo, instead of a File_Knob.
As far as I know, File_Knob calls nuke.getFileName(), but doesn't let you
tap into the arguments of that call. Instead, you could build your own "File
Knob" using an EvalString knob and a PyScript knob (you can even give it a
folder icon to make it look more like a standard File_Knob).
It may not be as pretty as using a regular File_Knob, but the advantage is
that you can then have full control over the actions triggered when you
press the "file" button, including the use of getClipname or getFilename
with any arguments you want (filter pattern, default path, etc).
Here's an example:
##################
n = nuke.createNode('Group')
stringKnob = nuke.EvalString_Knob('image_file')
buttonKnob = nuke.PyScript_Knob('fileOpen', '<img
src=":qrc/images/File_Knob.png">')
buttonKnob.setValue("""
file = nuke.getClipname('Choose sequence...', pattern = '*.png', default =
'/default/path')
if file:
nuke.thisNode()['image_file'].setValue(file)
""")
n.addKnob(stringKnob)
n.addKnob(buttonKnob)
###################
Hope that helps.
Cheers,
Ivan
