Re: [Newbies] Some sample code to help understand Morphic applications
An RSS reader? You may want to work with Derek O'Connell, who is working on a similar newbie project. His project is a Stockchart that shows rising companies in blue and falling ones inred, and he has also written a simple RSS reader: http://minnow.cc.gatech.edu/squeak/5873Looks interesting - I'll have a closer look at that, thanks! ___ Beginners mailing list Beginners@lists.squeakfoundation.org http://lists.squeakfoundation.org/mailman/listinfo/beginners
[Newbies] problem with big dictionary

Starting things off with SampleImageViewerMorph newin a workspace isreally basic, but it is something that us new guys just don't get untilwe've done a few examples. That's been my experience too - once you understand the 'shape' of the solution you're trying to build, it's easier to use the browsers to find relevant code to learn from I gather that the final class in the listing willgenerally be the one that you start the program with--bottom-up programming, as in Forth?If I understand you right, then the answer's 'no' - everything's listed alphabetically in the browser - it's just a co-incidence that this reflects the level of the classes in this case. System browser, rt click on class category, then select printOut is another command that isn't talked about much, and I guess you have to just knowthat the .html output listing is not really HTML, but now I have a printedlisting with lots of comments, and a running program with buttons and graphics.Nice!

[Newbies] Is there a way to watch all the messages flowing in Squeak?
Although everything in Squeak is open, I find it quite hard sometimes to track down what is calling what. It would be great if I could open up a window to see which object is being called when I e.g. right click on the surface and bring up the World menu etc. Is there some way to turn on the debugger and just let it run, or something like that? thanks Andy B___ Beginners mailing list Beginners@lists.squeakfoundation.org http://lists.squeakfoundation.org/mailman/listinfo/beginners

Thanks for this workaround - it works now. But highest value for -memory parameter is 880MB (on my Ubuntu Linux). If I try greater value than 880MB, squeak falls down with message: bad address: negative. pf Klaus D.

[Newbies] Re: problem with big dictionary
Petr, yes, there seems to be a limit = 1GB in the 32bit VM's. It is perhaps possible to bypass the problem by using the -mmap argument but I have no experience with that. Perhaps you find a more recent VM executable which fits: - http://www.squeakvm.org/unix/ IIRC 1GB of memory is addressed in the 64bit VM's. /Klaus On Wed, 18 Oct 2006 17:23:00 +0200, Petr Fischer wrote: Thanks for this workaround - it works now.

Debugging the UI is tricky, because the debugger uses the UI. But you can see what methods get called using the profiler. For instance, you can do this in a Workspace to debug the Morphic UI for 4 seconds (4000 msec): now := Time millisecondClockValue. TimeProfileBrowser spyOn: [ [ Time millisecondClockValue - now 4000 ] whileFalse: [ World doOneCycleNow ] ] After 4 seconds, you will see a TimeProfileBrowser pop up that will show what messages were called, and how many times. This works by interrupting the execution of the block given to spyOn: every millisecond or so, so it can miss methods that don't get called very often or are very fast. You can also use the simulator to run code; this is much slower, but won't miss anything. Note that some primitives (for instance, in the BalloonEngine) won't simulate properly. now := Time millisecondClockValue.
