Morphic vs. MVC. I think it would be very interesting to see someone take MVC to the level of mouse based interaction that Morphic already supports. <blockquote cite="mid:212DC432-7D11-4F45-829D-8F579C43A0CA@heaveneverywhere.com" type="cite"> <div>Second, the base classes (Morph et al.) are pretty heavy-weight; Morph has 6 instance variables, and you’re up to 10 or more by the time you get to the interesting classes. This makes it hell on the garbage collector for complex UIs (like music notation) where you might have thousands of display objects on the screen, and want to scroll or page quickly.</div> <div>I really want to port my Music framework (Siren = <a moz-do-not-send="true" href="https://github.com/stpope/Siren9">https://github.com/stpope/Siren9</a>) off of VisualWorks, but I refuse to use Morphic, so I’m looking at the new UI frameworks being built in Pharo. Pharo is way bloated, though, which is why I was hoping somebody was porting Sparta/Block/Brick to Cuis...</div> </blockquote> Well, the real question is: Is Sparta/Block/Brick lighter than Morphic? Would it give better performance? I guess someone has to try. I believe it was John Maloney who once said that even the little dot on top of the 'i' should be a Morph. Still, in Morphic, a text editor is a single morph, as you say, for performance reasons. Perhaps a morph supporting music notation could be built in a similar way, or perhaps a middle ground design, where each staff is a morph. I wonder if in MVC or Brick having an object for each note would give good performance, or at least any better than Morphic. Just thinking out loud. <blockquote cite="mid:212DC432-7D11-4F45-829D-8F579C43A0CA@heaveneverywhere.com" type="cite"> <div> </div> <div>Keep up the great work!</div> <div> </div> <div>Stephen</div> <div> <div> <div> <div> <div> <div> -- </div> <div> </div> <div> Stephen Travis Pope Ojai, California, USA </div> </div> </div> </div> <div> <img moz-do-not-send="true" src="cid:55B397C7-3D20-4E60-A051-4564245235A7@sd.cox.net"> <a moz-do-not-send="true" href="http://HeavenEverywhere.com">http://HeavenEverywhere.com</a> <a moz-do-not-send="true" href="http://FASTLabInc.com">http://FASTLabInc.com</a> <div> <a moz-do-not-send="true" href="https://vimeo.com/user19434036/videos">https://vimeo.com/user19434036/videos</a> <a moz-do-not-send="true" href="http://heaveneverywhere.com/Reflections">http://heaveneverywhere.com/Reflections</a> </div> <div> <div> <div> </div> <div>--</div> </div> </div> </div> </div> </div> </blockquote> Thanks! <pre class="moz-signature" cols="72">-- Juan Vuletich <a class="moz-txt-link-abbreviated" href="http://www.cuis-smalltalk.org">www.cuis-smalltalk.org</a> <a class="moz-txt-link-freetext" href="https://github.com/Cuis-Smalltalk/Cuis-Smalltalk-Dev">https://github.com/Cuis-Smalltalk/Cuis-Smalltalk-Dev</a> <a class="moz-txt-link-freetext" href="https://github.com/jvuletich">https://github.com/jvuletich</a> <a class="moz-txt-link-freetext" href="https://www.linkedin.com/in/juan-vuletich-75611b3">https://www.linkedin.com/in/juan-vuletich-75611b3</a> <a class="moz-txt-link-freetext" href="https://independent.academia.edu/JuanVuletich">https://independent.academia.edu/JuanVuletich</a> <a class="moz-txt-link-freetext" href="https://www.researchgate.net/profile/Juan-Vuletich">https://www.researchgate.net/profile/Juan-Vuletich</a> <a class="moz-txt-link-freetext" href="https://patents.justia.com/inventor/juan-manuel-vuletich">https://patents.justia.com/inventor/juan-manuel-vuletich</a> <a class="moz-txt-link-freetext" href="https://twitter.com/JuanVuletich">https://twitter.com/JuanVuletich</a></pre> </body> </html>
