The only resource I found are in the answer here, which is very complete but doesn't cover everything. So:
- What is ExportHelper? How does adding it to a class declaration modify the execute method in order to call the file dialog?
- Why is there no documentation about it on doc.blender.org
- What are all the variables related to it (
filename_ext,filter_glob,use_setting, and that's all?) - Where may I found some info about it?
(Additional : answer mentioned above indicates to look at Templates > Python > Operator File Export, which "Templates" is this reffering to?)
