P6: How to get focus for mouse wheel event
by Hilaire June 21, 2017

June 21, 2017

Hi, With Dr. Geo under P6 I have a usability regression with the GeneralScrollPane of the File thumbnail dialog: This dialog does not have any more the focus when open by default. It is a problem when the user wants to browse with mouse wheel the sketch previews. Indeed he needs to first click on the dialog then he can browser with the mouse wheel. The user click should be unnecessary. How to ensure the mouse wheel event are sent by default to the GeneralScrollPane? It was the case with P3. Hilaire -- Dr. Geo http://drgeo.eu

Re: [Pharo-users] Autoformatting in SystemBrowser
by Marc Hanisch June 21, 2017

June 21, 2017

Hello, it's me again still struggeling with the same issue on two different machines: Ubuntu 16.04 and Fedora 25. On all machines the same behaviour, I'm getting the error: "Information Pharo cannot locate the sources file named /home/marc/PharoWorkspace/Pharo/pharo6.0/bin/lib/pharo/5.0-201705310241/PharoV60.sources. Please check that the file is named properly and is in the same directory as this image." I'm wondering why Pharo is looking in this folder, because the source file is present in the shared folder, where also the default Pharo6.0.image and Pharo6.0.changes live in: /home/marc/PharoWorkspace/Pharo/pharo6.0/PharoWorkspace/Pharo/pharo6.0/shared/PharoV60.sources Any ideas? I'm a little helpless... ;-) Btw. this is Pharo 64bit...

Maybe my workflow is wrong? When I want to store an image somewhere else, I always left+click and select save as... to save my image. As far as I understand Pharo, it then saves the image and a changes file in the selected directory. The sources file should stay in the Pharo distribution folder, under the share directory, shouldn't it? The sources file is present in my share folder, I don't know why Pharo looks into pharo6.0-64/bin/lib/pharo/5.0- > 201705310241/ (that's the path from the error message). > > ...BTW I'm wondering why the mailing list sends my mails as .eml attachments?

Regression with PNGReaderWriter in P6
by Hilaire June 21, 2017

June 21, 2017

The code bellow decodes the PNG picture just fine in P3, in P6 it can't! I suspect changes in PNGReaderWriter>>nextImage However the version shows no history of edit :( One should add this code below in a test for PNG.

Hi - I'm porting some stuff to Pharo 6. The old stuff uses OSProcess and I'd like to find all the references to classes from that package in my package. Is there a little bit of code that does that? thanks Paul

Cairo related crash with Dr. Geo
by Hilaire June 20, 2017

June 20, 2017

Hi guys, Does this error related to Cairo makes sense to you? It is happening on DrGeo 17.07 (based on Pharo3), on a LinuxMint 18.1 64bits based on Ubuntu 16.04. Dr. Geo apparently crash quite quickly All the necessary 32bits libs are installed. It seems LinuxMint18.1 Cairo is 1.14.6-1 and ubuntu 14.04 1.13.0~20140204-0ubuntu1.1 where DrGeo is know to work perfectly.

Does Teapot's (ZnRequest's?) session ever expire? What is the expiry period? I can't find where it's specified or configured. -- View this message in context: http://forum.world.st/Teapot-session-tp4951845.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

UUIDGenerator
by horrido June 20, 2017

June 20, 2017

Is there even one shred of documentation anywhere that shows how to use UUIDGenerator? A thorough Google search reveals nothing! All I find are reference materials. I'd like to see just one working code sample, no matter how simple. -- View this message in context: http://forum.world.st/UUIDGenerator-tp4951725.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

I would like to find files in Pharo like the UNIX find command: find . -iname "*.txt" -type f -print find . \( -iname "*.txt" -o -iname "*.csv" \) -print find . -maxdepth 2 -name "example*" -type f -print find . -type f -atime -7 -size +2M -perm 644 -print Do we have some package on top of FileSystem to make complex find searches?
