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

Hi Offray, The actual implementation of #saveContentsToFile: can be found in ZnHttpSaveContentsToFile>>#performOperation where you can see how ZnClient is invoked. Just copy that with signalProgress: true added and you should be good. Alternatively, you could wrap the first expression as follows: ZnSignalProgress value: true during: [ myUrl asUrl saveContentsToFile: file ] ZnSignalProgress is a DynamicVariable that is used by ZnClient to figure out if progress should be signalled. It takes precedence over the option #signalProgress. See #withProgressDo: if you are interested. HTH, Sven

Hi,

I'm using

myUrl asUrl saveContentsToFile: file

to download large files and is working fine. But I would like to add a progress bar to show the progress to the user. Previously I used

=============== [: bar | bar title: aString. [ "A classical ZnClient download with signalProgress: true;" ] on: HTTPProgress do: [ :progress | progress isEmpty ifFalse: [ bar current: progress percentage ]. progress resume ]. ] asJob run. ===============

but I don't know how to signal progress with "saveContentsToFile".

Any hints?

Thanks,

Offray
