When the UI thread is really busy, updating the UI can be problematic. An extra fork seems to help: (FileLocator temp / 'PharoV30.sources') ensureDelete. [ [ :bar | bar title: 'Downloading Sources...'. [ ZnClient new url: 'http://files.pharo.org/sources/PharoV30.sources'; signalProgress: true; downloadTo: FileLocator temp ] on: HTTPProgress do: [ :progress | progress isEmpty ifFalse: [ bar current: progress percentage ]. progress resume ] ] asJob run ] fork. > On 13 May 2016, at 01:00, Offray Vladimir Luna CÃ¡rdenas <offray.luna(a)mutabit.com> wrote: > > Hi Sven, > > Thanks for your quick answer.

Interesting to know. But I see this already seems hard coded... Date nameOfDay: 1 "--> #Sunday" Timespan subclass: #Date poolDictionaries: 'ChronologyConstants' ChronologyConstants class >> initialize DayNames := #(Sunday Monday Tuesday Wednesday Thursday Friday Saturday). Also seems to have changed at some point, with the historical nameOfDay recorded in the Terse Guide [1] circa 2010 shown to be different. Perhaps this is something we should make a regional preference. Was there any ongoing works on other regional preferences? [1] http://wiki.squeak.org/squeak/5699 cheers -ben

Hi again, This implementatin http://ws.stfx.eu/FSNU7TV3O5FY also shows a static downloading progress bar without any download, but the download works. Ofcourse any example with another url for a smilar large file could work for me. I'm just testing with the file for this [1] (Soon a proper announcement).

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. I get a progress bar message, but not the advancements on it. What I'm missing? Cheers, Offray ps: The file I'm trying to download is covered by the Open Data Base License.

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.

Downloading large files with a progress bar

by Offray Vladimir Luna CÃ¡rdenas

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
