Hi,
I am trying to add a download button to my application to serve a 20MB application file. I don't manage figure out how to make button that triggers a download dialog ? I also wonder if MyFileLibrary is the right way to do so ? Thanks in adavance, @+Maarten, _______________________________________________ Seaside mailing list [hidden email] http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/seaside |

Ideally something like Apache or lighty that supports streaming, ideally sendfile. Your Squeak webserver might or might not be up to the job. > I don't manage figure out how to make button that triggers a download dialog ? Buttons are not really well suited for this, anchors work way better. What probably is the most reliable thing is: renderContentOn: html html form with: [ html submitButton callback: [ self session redirectTo: 'http://url.to/my.file ]; text: 'download' ] > I also wonder if MyFileLibrary is the right way to do so ? No, don't even think about it.

I found a Class called AttachmentFilename though in HTTP so maybe this is the one to use. Maybe I can simply fork the download action in a new session ? @+Maarten, >> This download method is available as an extension to base seaside in >> repository http://www.squeaksource.com/Jetsam >> >> cheers >> >> Keith >> _______________________________________________ >> Seaside mailing list >> [hidden email] >> http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/seaside >> > _______________________________________________ > Seaside mailing list > [hidden email] > http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/seaside > _______________________________________________ Seaside mailing list [hidden email] http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/seaside |

Configure Apache or lighy to serve the file. As it just turned out Swazoo is not up for the task and I wound't be surprised if Kom is not either. Again and again we tell people to use an Apache frontend to serve static files, exactly because of this. But no. It has to Smalltalk, it has to block the image, it has to be copied three or four times in the image, it has to block the session. 2. Use an achor. HTML is not really a GUI framework where a button is simply a widget. Certain things are best done in a certain ways. Anchors are what you need here. html anchor url: 'htttp://url.to/my/file/on/apache.extension'; with: 'Download' Cheers Philippe > @+Maarten, > > >> This download method is available as an extension to base seaside in > >> repository http://www.squeaksource.com/Jetsam > >> > >> cheers > >> > >> Keith > >> _______________________________________________ > >> Seaside mailing list > >> [hidden email] > >> http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/seaside > >> > > _______________________________________________ > > Seaside mailing list > > [hidden email] > > http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/seaside > > > > > _______________________________________________ > Seaside mailing list > [hidden email] > http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/seaside > _______________________________________________ Seaside mailing list [hidden email] http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/seaside |

Well, don't judge too fast because you could eat your words too soon :) It seems that this can happen to you in case of Swazoo. Namely, a problem is identified and solution is on the way. In days!
