Hello, you can have a look at Rubric too. see RubTextFieldExample. also RubPluggableTextMorphExample. to see rubric text field in action within a user interface.

The best Smalltalk teacher is usually the image :) Browsing references to PluggableTextFieldMorph (cmd-shift-N on Mac), it seems that many users send #on:text:accept:readSelection:menu: to supply the model info for callbacks ----- Cheers, Sean -- View this message in context: http://forum.world.st/Using-PluggableTextFieldMorph-tp4831375p4831394.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Using PluggableTextFieldMorph

by Jigyasa Grover

Hi With reference to my earlier query 'Getting a user input string using Morphs' <http://forum.world.st/Getting-a-user-input-string-using-Morphs-td4831121.ht…> I have come across 'PluggableTextFieldMorph' which seems to be the one I was looking for. Could anyone pls help so as to how could I use the 'getText' method to retrieve the user input string.

I don't need concurrent write access, and I am anticipating the graph remains far bellow 5MB, likely bellow 100 KB. I am just testing it and one fuel file per graph looks great, and it is so comfortable! Thanks Hilaire -- Dr. Geo http://drgeo.eu http://google.com/+DrgeoEu

The needed change for this low level access to morph is probably a small one, related to ActiveHand, but I have not yet move to 4.0. In the other hand, you may want to use higher level approaches suggested by Pharo fellows.

Re: [Pharo-users] Using GTSpotter how do I find an implementor of #accept ?

Yes this can be improved and it is not difficult, for example you can add this method to GTFilterImplementor>>applyFilterWithQuery super applyFilterWithQuery. items sort: [ :a :b | (self itemFilterNameFor: a) size < (self itemFilterNameFor: b) size ] this will sort the result list by the size of the selector name. So, if there is a perfect match, it will be listed first. (BUT only in the implementors category if you "dive-in", not in the 5-elements-result-preview-list). Maybe there is a better way without sorting. (We can modify applyFilterWithQuery for the implementors filter, to put perfect matches at the begining of the list). But all this is not easy to discover. Spotter classes make some heavy use of delegation, many operations are split and delgated to subclasses (GOOD!) many classes aren't documented (BAD!) and this makes it really difficult to catch how all this is supposed to work together. nicolai > > > Thanks > > > Paul >

Using GTSpotter how do I find an implementor of #accept ?

by Paul DeBruicker

when I hit shift+enter and type 'accept' I get things that are not #accept, e.g. #accept: and AbstractAcceptor. If I add a space after accept it doesn't help. What do I not understand? Thanks Paul

Re: [Pharo-users] Mac Squeak binary virtual machine for Squeak 3.10.2

by Norbert Hartl

It is always the same question. Why do you upgrade if you don't want things to change? It is close to obvious that there is no one paradigm that is so perfect it does not need change. If there is no new feature you need there is no reason to upgrade. Of course new releases fix bugs and at the same time the introduce incompatibilities. That's how it goes. I doubt you find anything different in any other language. The only thing you can do is asking for help.

Since then, I have been working almost exclusively with Smalltalk. My company invested in a VW class library of more than 100,000 lines of Smalltalk code and used it in our consulting. A strong selling point was that our tenders were accompanied by a demo version of the program we offered to deliver. Our library and applications were repeatedly threatened by new versions of VW.

My new programming paradigm, DCI, is supported by BabyIDE that runs under Squeak 3.10. I have ported BabyIDE to 4.5, but there are new bugs caused by differences between 3.10 and 4.5. The result is that I have reverted to 3.10 because it's too much hassle to run after the stream of Squeak releases. I thought Pharo would be better, but their mailing list conversations indicate that they do not understand that developers need a stable foundation for their work. > > The result is that I too leave Smalltalk and concentrate on other environments. A pity, because I still believe Smalltalk has the potential to become a superior environment for non-professional programmers.
