Re: [Pharo-users] Downloading large files with a progress bar

[Offray Vladimir Luna Cárdenas]

Hi again,

Umm.... this is kind of strange. When I try with the Sven code 
downloading the Pharo, downloading progress bar works, but when I try 
the follow one, download works and forking lets me use the environment, 
as with Sven's but progress bar don't advance:

=================
OffshoreLeaksDB class >>downloadDatabase
    "I download the data of the panama papers from its page at the 
DataHub community repository:
    https://datahub.io/dataset/panama-papers
    "
    [[ :bar |
        bar title: 'Downloading Database...'.
            [
                ZnClient new
                    url: 
'https://datahub.io/dataset/06f27df3-ec88-47ea-b428-7ec138f7835e/resource/50a9bda8-e44a-4aac-b265-d07fabde5612/download/offshore-leaks.sqlite.zip'; 

                    signalProgress: true;
                    downloadTo: FileLocator temp
            ]
                on: HTTPProgress
                do: [ :progress |
                    progress isEmpty ifFalse: [ bar current: progress 
percentage ].
                    progress resume ] ] asJob run ] fork.
=================

As an alternative I'm thinking in creating a Roassal animation for 
background processes, similar to the rolling circles in the browser, 
tablet of phone, to show that something is advancing, but you still need 
to wait... Anyway, if someone can tell me about why this is happening I 
will really appreciate it.

Thanks,

Offray

Hi Sven,

Thanks for your quick answer. I tried both approaches but I'm 
missing something. See my last attempt at 
http://ws.stfx.eu/KBVBAP72IWOO with the last one.
That last code makes no sense and is not how the API is designed to 
be used.

Sorry. I was tired and poking the code to see what was wrong. Your 
example with fork and Pharo.sources work pretty well. I will implement 
it.

Thanks,

Offray
