Spec #focusOrder

by Julien Delplanque

Hi, I am trying to manage the focus order of my widget that uses sub-widgets with their #focusOrder defined. How do spec manage nested focus order? I see in the implementation that it is simply an OrderedCollection. I does not behave as I expected, when I add my sub-widgets to the focus order, the focus is given to the first sub-widget and I can not access the second sub-widget using tabulation. For example lets imagine WidgetA contains 2 buttons and WidgetB contains 2 buttons. I can only access the two buttons of WidgetA using tabulation. How can I deal with that? Thanks in advance, Julien

state of pharo on tablets

by Peter UhnÃ¡k

Hi, does anyone knows what is the current state of Pharo on tablets / state of touchscreen? I'm considering buying a new tablet and I would like to play with Pharo there, if that is currently possible (I've seen some videos, but I am not sure if that was special hardware or whatnot). So are tablets supported? Android? Windows (10)? Thanks, Peter

Re: [Pharo-users] How to generate "Content-Type: application/octet-stream" with Zinc client

by Sven Van Caekenberghe

Hi, That is an odd request. Can you produce it with curl ? You could try to make your part something like this: | part | part := ZnMimePart fieldName: 'file' value: '123'. part headers at: 'Content-Type' add: ZnMimeType imageJpeg. part. This creates two values for Content-Type.

This txt file is the output of an external framework. I cannot change its structure. I believe that performance can be indeed an issue depending on the size of the file and the number of operations executed. I will study other alternatives. Cheers,

Hi Martin, Last year there was a poster made by Adam adam(a)234.cz I don't know if that fits your goals, the poster license or if he's still around, maybe you could check with him if there's an update.
