Uploader and Downloader could be Dialogs and not Widgets

[KenT2]

I have used the new uploader and downloader. I have also been doing a lot of development of my app and it is now on github at https://github.com/KenT2/manager-for-pipresents

All my development and testing has been on Pi for server and Internet Explorer and Firefox running on Windows. Most museums will be Windows/IE so that is my most important user.

The uploader and downloader upload and download fine with one exception (see next issue) I have one problem with each of them, it is not possible to dynamically change the destination directory for the uploader or the source file for the downloader because they are defined as widgets in the main page rather than dialogs.

Uploader would be much better if you could do

   def on_a_click(self):
upload_dialog=gui.FileUploader(600,600,self.media_dir+os.sep)
    upload_dialog.set_on_success_listener(self,'on_media_upload_success')
    upload_dialog.set_on_failed_listener(self,'on_media_upload_failed')
    upload_dialog.show(self)

which would be executed as a result of a button click or menu click etc. event . It would open the browser's file selection dialog directly. Downloader would be similar and open the browser's download box.

    profile_download=gui.FileDownloader(600,600,'Click to download current profile',self.file_to_download)
    profile_download.show(self)
