Seeking help to build an accordion widget for GUI of sQuick
by Jigyasa Grover July 1, 2015

July 1, 2015

Hello All :) I am a newbie in Pharo and have started to build my first application i.e. an offline text search application namely searchQuick. You all are welcome to fork the code (https://github.com/jig08/sQuick_new) , try the infancy application and send in suggestions. Currently, I have built the basic structure of the application using Morphs and have a lot to cover on the GUI part. sQ basically returns the list of file titles from the pre-loaded text files present in the resource folder when a string is searched for. I plan to build an accordion widget (https://jqueryui.com/accordion/) or something similiar to view the results. I seek help on the implementation of this part. Looking forward to a positive response. Regards Jigyasa -- View this message in context: http://forum.world.st/Seeking-help-to-build-an-accordion-widget-for-GUI-of-… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

loading with gofer without network
by Christophe Demarey July 1, 2015

July 1, 2015

Hi, I'm trying to load a package (mcz) from the package cache with Gofer. |gofer| gofer := Gofer new repository: MCCacheRepository uniqueInstance; repository: (MCSmalltalkhubRepository owner: 'Seaside' project: 'Grease11'); version: 'Grease-Core-JohanBrichau.94'; disableRepositoryErrors; load As you see, I gave 2 repositories (the first is local, the second one is remote) to Gofer. If you try to execute this code without the network, it will failed! It shouldn't because the mcz is in the package cache. I think it is a bad behavior of Gofer. It does not have to resolve references for ALL the repositories because, at the end, you only use one. I want to change this behavior to only get the first resolved reference (no need to iterate more). If not acceptable, I could only ignore repositories not reachable (disableRepositoryErrors does not work for this use case). Is it ok to change it? Christophe

stream not working with MemoryFileSystemFile
by Torsten Bergmann July 1, 2015

July 1, 2015

Christophe Demarey >I tried to create an in-memory file as following: >(MemoryFileSystemFile named: 'Foo') > writeStreamDo: [ :stream | stream nextPutAll: 'bar' ] > >Then I get an improper store into ByteArray. It looks like Character cannot be store in a byte array. >I do not know if the bug is on the memory file system part or other. >Any idea? Why do you use MemoryFileSystemFile directly. Usually the FileSystem is the starting point. And there it works: |fs file| fs := FileSystem memory. file := fs / 'test'. file writeStreamDo: [ :stream | stream nextPutAll: 'bar' ]. fs inspect The nice thing is that you can now browse the file system and file contents with the new GT Inspector. Thanks T.

Hi Ronie, since we switch here from OS X 10.10.2 to 10.10.3, your OpenCL framework doesn't not work anymore ... We crash Pharo everytime we try to use GPU. This is an except of the crash log: Process: Pharo [21039] Path: /Applications/Pharo.app/Contents/MacOS/Pharo Identifier: org.pharo.Pharo Version: Pharo 0.2.7-2015.04.20 (21.0) Code Type: X86 (Native) Parent Process: ???

pharo looses font settings on linux with retina screen
by Martin BÃ¤hr July 1, 2015

July 1, 2015

hi, i am running pharo 40614 on linux on a mac with a retina screen. i have not tested this on a normal laptop yet, so i don't know if the retina resolution is the problem or the pharo version i am using. probably a bit of both. the worst issue is that when i restart an image, the font settings are partially lost and reverted to the original size, which is to small to read on such a screen. and restoring the font size requires me to reopen all the affected windows. there are also issues with some widgets not resizing to the full size of the font, making the text only partially readable. and then there are widgets that have the correct size, but the font remains small. and all that is not consistent, sometimes all sizes are correct, sometimes it is a complete mess. pretty much every time i restart after resetting the font size i get different results. it makes pharo practically unusable on this machine, because i am spending to much time fixing fonts, and am not getting any work done. is there some other setting to adjust to the resolution besides selecting a huge font? greetings, martin. -- eKita - the online platform for your entire academic life -- chief engineer eKita.co pike programmer pike.lysator.liu.se caudium.net societyserver.org secretary beijinglug.org mentor fossasia.org foresight developer foresightlinux.org realss.com unix sysadmin Martin BÃ¤hr working in china http://societyserver.org/mbaehr/

Pharo image processing library
by Peter UhnÃ¡k July 1, 2015

July 1, 2015

Hi, is there any image (as in picture) processing library in the likes of Python's PIL(http://effbot.org/imagingbook/image.htm), or even (highly unlikely) something like OpenCV (http://opencv.org/)? Thanks, Peter
