Yes, the blocking nature of the progress bars is an argument for putting it central. I just wanted to bring the preference to your attention. Now, doing away with unused preferences is a powerful way to simplify the system. Maybe the best strategy is to start using your new code in the launcher and see how it goes. If all goes well, people will start requesting that progress bar for the main image ;-) On 08 Sep 2014, at 13:37, kilon alios <kilon.alios(a)gmail.com> wrote: > It should not be a problem because it affects only the PharoLauncher image and not the images you download with PharoLauncher so the old progress bar will remain in those images. > > Its personal taste of course but let remember here that a common complain about smalltalk is that it looks weird and for some people ugly.

Re: [Pharo-dev] Trying to scale and reposition the progress bar for PharoLauncher

by kilon alios

It should not be a problem because it affects only the PharoLauncher image and not the images you download with PharoLauncher so the old progress bar will remain in those images. Its personal taste of course but let remember here that a common complain about smalltalk is that it looks weird and for some people ugly. How many progress bars you have seen up left ? What advantage is there for a progress bar to be up left ? Also because when performing such jobs pharo freezes and does not allow for further interactions with the user until the job ends it makes more sense for the progress bar to be in the middle , bigger size so its very visible even from distance if the user decides to leave the screen to grab some coffee or fight with his light saber and if possible even display a "Please wait..." message so the user / beginner Pharoers knows this is not a bug or he /she did not brake Pharo. I am not saying Pharo should be an exact copy of the GUIs out there but at least we should respect the user habits and broke those habits only if it is necessary.

Nice, but did you see SystemProgressMorph class>>#settingsOn: ? In other words, there are preferences for the location of the progress bar, these should probably be honoured.

ok with a bit of help I was able to figure things out, it turns out that it was simple to do difficult to understand :D so here is my answer http://stackoverflow.com/questions/25708970/trying-to-find-the-progressbar-… I also attached the new progress bar i customised and the old for comparison as attached images â Personally I would make my code the default Progress Bar for entire Pharo including all operations because its annoying to be that small and up there. This should work well even if there are multiple Progress Bars displayed. But for not its PharoLauncher only progress bar. How I add this code to PharoLauncher ? do I use just the development mode of PharoLauncher and Commit ? I dont want to mess anything up. Next step would be to add an info box for each image so people know what they download before downloading it.

XMLPullParser hex bug

by Tommaso Dal Sasso

Hello everybody, I found a bug while playing with the XMLPullParser: When using XML entities encoded in hexadecimal the parser throws an exception. For example: 
 is the hexadecimal encoding of 
 which is the line feed. If you try to parse: '<tag contents="one&#xAtwo" />' you get a "Expected Number" error. I investigated the problem, and found that it is caused by the method XMLPullParser>>readNumberBase: If the base of the parsed number is not 10, it executes the following lines: numberString := self nextUpTo: $;. self stream skip: -1. [...] However, the method nextUpTo: does not exist. A MNU is then raised and handled in nextCharReference: by a greedy "on: Error do: [:ex | self errorExpected: 'Number.']." thus causing the exception. The solution is either to implement nextUpTo: or to change it in one of the two existing methods: nextUpToAll: or nextTrimmedBlanksUpTo: Example: numberString := self nextUpToAll: ';'. Also, in the following line, it calls the accessor "stream", which does not exist and causes the same problem. The solution here is to change self stream skip: -1. into stream skip: -1. The following two test cases show the problem. The first one shows the correct behavior: XMLPullParserTest>>testASCIIEntity | parser | parser := XMLPullParser parse: ' <tag contents="one
two" />'. self assert: (parser next at: #contents) equals: (Character lf join: #(one two)) The second one shows the error: XMLPullParserTest>>testUnicodeEntity | parser | parser := XMLPullParser parse: ' <tag contents="one
two" />'. self assert: (parser next at: #contents) equals: (Character lf join: #(one two)) I hope it is clear enough. I can also commit the fix myself, if you give me write access. Thanks, Tommaso

yeah yeah I see it now, there actually many announcers (3 of them ) all seem to signal SystemProgressMorph , oh boy this will be a tricky one .

From displayProgress: , asJob brings you to Job, which has no morph at all. But, on the class side of Job, you have a job announcer (instance class variable jobAnnouncer). Inspect that variable, search among the subscriptions of the announcer, and you'll find SystemProgressMorph. A good use case of a fairly good design which is a lot harder to unravel than it should be, due to the lack of tools to explore announcer / subscription relations. Thierry
