是否可以将gtk.FileChooserDialog / gtk.FileChooserButton设置为仅允许用户选择文件夹/目录?
也许我添加了一个目录过滤器来实现这一目标?如何制作以便用户只能选择文件夹?
email_dialog = gtk.FileChooserDialog(title="Select folder",
buttons=(gtk.STOCK_CANCEL, gtk.RESPONSE_CANCEL, gtk.STOCK_OPEN, gtk.RESPONSE_OK))
email_filter = gtk.FileFilter()
email_filter.set_name("Folder")
email_filter.add_pattern("*") # whats the pattern for a folder
email_dialog.add_filter(email_filter)
