So subsequent windows of the same nature open in the same position and size. What must I do to make VW save the window position and size explicitly? It is not clear when that info is remembered or how to change what is remembered.

The exception handler in this VW 7.5 method was hiding the problem: InputFieldView&gt;&gt;hasEditValue "Answer true if the receiver contains a valid edit value, otherwise answer false. This method should be used in conjunction with #editValue to avoid having to handle the wide range of exceptions that may result when conversion is requested for invalid input." ^[self editValue. true] on: Object errorSignal do: [:ex | ex return: false] Cincom, please consider changing the handler to at least write something to the Transcript when an error happens. Take menus for example, when there are any problems with menus the default behavior is to write a message on the Transcript that says what the error was and how to enable a debugger instead </pre> Paul Baumann 2013-06-13T15:46:24 http://comments.gmane.org/gmane.comp.lang.smalltalk.vwnc/25150 <pre>Hello there, I have an interesting problem to resolve. I have an application which needs to be translated to the multiple languages. I did load the "I18n" package which help to find and fix the irregularity in the messages, like malformed messages, key collisions, etc. The application has a plenty Dialog interactions like Dialog warn:, request, etc. I can find all the senders or #warn: for example and replace strings from 'Warning' to the message form: #Warning&lt;&lt;#dialogs&gt;&gt;'Warning'. The problem I have is the UI Specs. Are there any tools available to help me identify where the translations are missing from Button labels, labels, Menu Items, Window labels, etc. Any pointers are greatly appreciated.

My only concern, is that this has been along time coming. Travis started with Cairo in 2006 - he's left and seven years later it is still in preview and still being "tossed around". It seems like it's very much a "do it yourself" deal - which is all well and good if you have the chops and time to delve into the DLLCC stuff and compile libraries etc. The examples in Store are flaky, and Pango seems almost impossible to get to work. I've not been too fussed about the UI in VisualWorks up till now, but it would just look "old and clunky" on the apps store in its current form. I know this has been discussed at length and various avenues explored, but I would put this at the top of the list - please tell Arden!

I want it to look nice, cross platform and zoomable, and from what I've seen good results can be obtained with Cairo. Unfortunately as I did a bit deeper, it looks like it's still very much experimental and a bit of a "black art". I've been unable to get Pango to work. I know Cairo has been on the radar for a few years now, but it is still unsupported by Cincom and third party development seems to have waned. What is the general consensus? Should I pursue this avenue or maybe look at using SWIG to hook up to Qt (which I have used successfully from Ruby, and looks quite nice), or something else? All viewpoints appreciated.

I have to run some critical code, and prevent any interruption by the GC during the time of the process. Looking in the archive I found http://www.parcplace.net/list/vwnc-archive/0604/msg00070.html about preventing the GC to run. My process is calling a C function that callback a Smalltalk block every 0.00853333 second. This is working well, until the GC runs. If I protect the call with [ .... the main call ] valueUninterruptably I have effectively no interruptions while the process is running. BUT : I have to give the user a way to stop this process at any time. If I give the user an opportunity to stop, I give at same time an opportunity to the garbage collector to interrupt the process. How can I give to the callback block a priority against the GC, without being preemptive for user control ? Thanks for any suggestion.

Our Seaside application runs in VW, using several images, each with several GS sessions. One 'dispatcher' image communicates to each application image with OpenTalk for status and control, and redirects initial logins. All works fine. I wanted a simpler way to manage this multi-image setup, so I wrote a version that uses Polycephaly. All works: each drone is able to log in to GemStone and serve a Seaside interface on its own port.  Our web server setup allows for multiple shared GS sessions, and it works fine in the separate image configuration.  It also works fine if I spawn a DebugMachine instead of a ViritualMachine.  However, if I use a VirutalMachine, logging in the second GS session locks up the Seaside interface and I get an 'Connection can not reopen!' on the ExternalWriteStream for that drone. Any suggestions on how to diagnose this?   It's probably a unique mix of Polycephaly and GS; it would be cool to hear of another setup.
