>> Since last few weeks, I have been experimenting with Pharo as a tablet interface inside a tiny core Linux. The dev though happens on ubuntu. Some more playing around for a group of trainees with pharo on windows 7, platform I do not very much like.
>> 
>> How far is it a nice to have framework that provides for a complete UI, IDE like a tablet interface and behaves akin to android that has it's own AppStore, and application launcher in full screen on icon click.
>> 
>> Anyone can download the base, and proceed to download the app source, files archive thru an app installer, that verifies , validates and installs as well as creates a launcher icon ( I will provide the screenshots once I have them fine tuned)
>> 
>> Rest of ideas and process are similar to android marketplace or iStore, with definite controls on absolute stability and experience of the apps
>> 
>> Some observations i will like the veterans to clue me on forward
>> 
>> . I find Pharo 1.2 more stable than 1.3 latest... 
>> 
>> .  Is morphic capable of supporting error free runtime GUI
>>     I enjoy it's capabilities, but feel it demands more intrinsic Pharo, debugging ability to keep hacking n fixing. Crashes , damaged rectangle painting are just few of the troubles
>> 
>>     I expect a simple answer, not necessarily a longer explanation of morphic and it's issues with global coordinates, polling event handling which are nuisances. I have read thru as much of links, docs on morphic as i could find, little working on it, but not enough to get an expert hang of it.
>> 
>> . Is system browser the best to study for morphic or should I look through any other package..Debug n learn..
>> 
>> . Simple way to get an embedded submorph from it's chain by it's name, #subMorphNamed: does help but only in a limited way.. For those that it digs.
>> 
>> . Simpler way to bar extensions from a contributed older package, overriding base class methods, not really the final as in java but at least prevent overwriting methods. A listing post file in of uncompiled methods of this kind. Hacking in FilePackage does help.. But anything better and more complete...and part of a base system.
>> 
>> . Mechanism to autosave a defined package every method commit to a packagename.mcz by default to ease crash recovery, use monticello only when I need to version it as a done base.
>> 
>> . Event handling of mouseLeave mouseEnter of a PluggableTextMorph, the on:send: did not work, not that I have dug into it... But would like to link it to the models methods directly in the builder method interface like we do for PluggableButtonMorph click....
>> 
>> . Color of a morph is not updated when selecting it thru the halo. Minor hack i have here, to get thru.
>> 
>> . Why is extent attribute not updated when we use addMorph:fullFrame:  which changes the bounds for the submorphs in some cases at least as i have noticed in debug step thru.
>> 
>> . What are clear do not do rules in using morphic framework as it exists today, as people have already experienced and attempted.
>> 
>> . Debugger stepping through has most times an out of step highlighting. Any fix on this..
>> 
>> . Settings window seems to have glitches in network settings, font updates from OS... 
>> 
>> . Autocompletion in windows seems to work on cr, but in Linux you have to type thru.
>> 
>> . The easiest way to have a core Pharo runtime image stripped of all dev tools, classes, size is not the limitation here, but stable n bug free base is a must.
>> 
>> . Tools n tips to make Pharo base with its loaded apps crash proof, just isolate and close the app that causes the problem rest of the image should continue to run.
>> 
>> 
>> issue not directly related:
>> .  Windows support for OSProcess, i have read the threads and the note from Eliot that it works on windows for cadence, but I cannot get it to work, the ProcessWrapper works but is limited. If I do get it working does it support interactive shell, viz i invoke a command that enters into it's own loop of inputs n output till you send a quit.
>> 
>> Lots more i will come up with in the next couple of weeks as I bring out what i have.
