Seaside / Getting Started
by Nicolai Hess Dec. 4, 2016

Dec. 4, 2016

Hi, I am currently reviewing the Seaside chapter of "Pharo By Example 5". The chapter is about Seaside 3.1 ( http://files.pharo.org/seaside/Seaside-3.1-portable.zip) But some parts the book refers to has changed, and I am asking here to see whether my changes/updates will be correct, and for some changes I don't know what to change. 1. configure seaside: open http://localhost:8080/seaside/config *I* think the following description expects this (old 2.8?) version output: (seaside_284_config.PNG) but instead, we get: (seaside_31_config.PNG) 2. And in the current (3.1) version, there is now login/password request. I will remove this from the description, but does anyone know how we would enable a login/password request for the config page? 3. Now, there is a step-by-step description how to add a copy of the example "counter" as "counter2", but the config page doesn't look like the description in any way. I guess the right description would be: change to the "examples folder" on the right, add push the "Add" buttton on the top pane (seaside_31_examples.PNG) instead of "Add entry point" (can not find this in any config page), we need to push the Add button and choose the dispatcher type: (seaside_31_examples_add.PNG) finally we need to set the root class ... Is this correct ? Is there already a updated documentation that describes this (adding a counter-example) with the newer interface? Thanks in advance nicolai (more questions will follow)

Nautilus with inline QA?
by Yuriy Tymchuk Dec. 3, 2016

Dec. 3, 2016

Hi everyone, I suspect that many of people want to have their Nautilus transformed into something like this: yes, the critiques are inlined. In fact I just needed to add 1 line of code, a the solution used in the MessageBrowser can be reused. On the other hand maybe someone prefers the list at the bottom and we are in code freeze anyway. What I think is: maybe we can integrate this (as essentially the functionality was âtestedâ in MassageBrowserâ already, but have it disabled by default and allow developers to turn it on using preferences? This way the ones who want this can turn it on and provide feedback whether it makes sense, while everything will stay the old way for the others. Cheers! Uko

Bloc: Ominous Black External Window
by Sean P. DeNigris Dec. 2, 2016

Dec. 2, 2016

Everything was working "okay" (although the examples seemed very slow to respond). Then, without apparent cause, now BlBasicExamples>>exampleGeometry (and all the other examples I tried) show a native window with blank (black) contents. Why is that happening and how does one debug something like that? Thanks. ----- Cheers, Sean -- View this message in context: http://forum.world.st/Bloc-Ominous-Black-External-Window-tp4925545.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.
