Preparations for FileChooser implementation (Part 7 - Deadly Modes)
There are 3 FileChooser portal methods:
- OpenFile
- SaveFile
- SaveFiles
But OpenFile has 2 boolean options ("directory" and "multiple) which mean there are actually 4 modes:
- select single file
- select single folder
- select multiple files
- select multiple folders
As such, we have 6 new modes to support, in addition to the "browse" mode (i.e., business as usual).
With these modes we can adapt the views and their actions, menus and behaviors
