Mondrian needs this. You can set different font for labels in Mondrian, and now it is broken. I will dive into this soon.

MySQL works on Mac and Linux but we have problems in Windows :( SQL Server works on Linux and Windows and wasn't tested on Mac. Firebird, Interbase and Sybase ASE are supported by OpenDBX but were never tested in SqueakDBX. So, they *should* work. > > Is PostgreSQL still required for Glorp? If you evaluate GlorpPharoLoader loadGlorpWithNativePostgreSQLDriver this will download the normal Glorp which requieres PostgreSQL. However, we have refactored this and now Glorp doesn't depends on a particular driver but to an abstract class DatabaseDriver. This refactor is now in SqueakDBX repo (it will then be in Glorp repo) with the name of GlorpDBX. So, if you download GlorpDBX you won't require PostgreSQL native driver, but SqueakDBX. You can also download only Glorp and use another driver. All of this stuff (GlorpDBX) is still in development and only works with PostgreSQL and Oracle > What if I want to > use Glorp with say SQLite? > You can, but not right now. You have to wait a bit ;) You will be able to use SqueakDBX with Sqlite or create a Glorp Driver (subclass of DatabaseDriver) for it if there exist another SQLite driver. > > Any comments on Glorp vs. SqueakSave? I must admit I have never (yet) used any of them to production applications. So I will give only my point of view: Glorp: - seems to have more "successful stories" - Has the CINCOM sponsor (in VW of course) - More flexible and useful for medium / big applications - Requieres time doing the mappings - The Squeak version is old (thanks DiÃ³genes is doing a new port) SqueakSave: - Not yet in stable release - Excellent situation for small / medium projects - You don't spend time doing mappings - I don't know if it works on Pharo. - Use MySQL or PostgreSQL but perhaps they create another adaptor for SqueakDBX Torsten know there is a SqueakDBX mailing list in case you have particular questions of it.

Is there a way to enforce this? all Pharo images contain nice fonts by default, a very cool code browser, syntax highlighting, completion...

Re: [Pharo-project] ToolBuilder vs MorphicToolBuilder vs PSToolBuilder

by Gary Chambers

Unless the default for ToolBuilder is explicitly set then PSToolBuilder will be used. Lists have an optional icon and double-click action. Windows use a PluggableStandardWindow. Panels use a PluggableThemedPanelMorph (theme generally specifies the fill style) Regards, Gary ----- Original Message ----- From: "Eagle Offshore" <eagleoffshore(a)mac.com> To: <Pharo-project(a)lists.gforge.inria.fr> Sent: Wednesday, August 19, 2009 2:40 AM Subject: [Pharo-project] ToolBuilder vs MorphicToolBuilder vs PSToolBuilder > What are the differences? > > It looks like most things are just using ToolBuilder right now - > correct? > > _______________________________________________ > Pharo-project mailing list > Pharo-project(a)lists.gforge.inria.fr > http://lists.gforge.inria.fr/cgi-bin/mailman/listinfo/pharo-project

Re: [Pharo-project] Native Windows

by Gary Chambers

We use StandardWindow that provides some benefits over SystemWindow. (ability to open full-screen for deployed applications, prevention of dragging except via titlebar etc.) As for builders, I assume you are refering to PluggableStandardWindow (used via PluggableWindowSpec/PSToolBuilder).
