mouse buttons in Linux, deleting certain morphs
by Sven Crouse April 13, 2011

April 13, 2011

Hi list. On a Linux host with default mouse mappings in X ( "Button Left"=1, "Button Middle"=2, "Button Right"=3 ) is there a setting to enable the Right Button as blue button without requiring the control key ? Regardless, I'm unable to delete certain morphs ( e.g. RectangleMorph, EllipseMorph ) in the World using the CTRL right-mouse button. To reproduce create a RectangleMorph in the World and try to delete interactively. Sven

Code Navigation: Navigation History in System Browser?
by Nick Chen April 12, 2011

April 12, 2011

Hi I was browsing through the draft chapter for Pharo By Example describing the Omnibrowser architecture (https://gforge.inria.fr/frs/download.php/27418/Omnibrowser.pdf) One of the screenshots (Figure 1.5 in the PDF) shows a browser with Back, Forward and History Buttons i.e. navigation history features. My specific questions: 1) What happened to this version of the browser? Is it possible to load the navigation history feature into the latest version of Pharo? I am currently using Pharo 1.2 2) The paper "Tackling Software Navigation Issues of the Smalltalk IDE" by RÃ¶thlisberger et al (http://www.bergel.eu/download/papers/Berg09d-SmalltalkIDE.pdf) implemented several useful features for code navigation in the Smalltalk IDE. Was their work ever ported to Pharo? Hopefully the authors of the paper are reading this list and can comment. The paper was very interesting for me because it described and proposed solutions for problems that I have encountered with code navigation in Smalltalk. Thanks! -- Nick -- View this message in context: http://forum.world.st/Code-Navigation-Navigation-History-in-System-Browser-… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

This was the first tutorial I read and it was really nice. Thanks a lot for this. Mariano ---------- Forwarded message ---------- From: Michael Perscheid <michaelperscheid(a)googlemail.com> Date: Tue, Apr 12, 2011 at 3:21 PM Subject: [Seaside] [ANN] Seaside Tutorial Ready for 3.0 To: seaside(a)lists.squeakfoundation.org Hi all, I would like to announce that we have updated the Seaside tutorial of the Software Architecture Group ( http://www.hpi.uni-potsdam.de/hirschfeld/seaside/tutorial) Now it can be applied with the current Seaside 3.0 version without any problems. Besides a revision of all chapters, we have especially changed the persistence chapter and added new sections about SandstoneDB, PostgreSQL, and GemStone. Most of the update was done by Lauritz Thamsen and Tobias Pape. Thank you very much. If you have any feedback, please let us know.

Help with TreeListMorph
by Adrien BARREAU April 12, 2011

April 12, 2011

Hi, I'm taking a look at the FileDialogWindow: FileDialogWindow new open. On the left, there is a tree. With the halo, I know it is a TreeListMorph. Here is my question: How can I know what is happening when I click on one of the little arrows which are just on the left of a directory name? With my changes, the subtree is very slow to be displayed and I don't understand what is called. Adrien.

So I wonder if we don't do a quick 1.3 release with out Rpackage and Opal. Form my side Opal definitly should not be in the critical path of the 1.3 release, if we talk about a quick release soon.
