And, at certain degree the same applies to my beloved ObjectArts and its Dolphin masterpiece. Regards, ps: Java is no Hype. You might like the language or not, but it has established throughout the last decade, and is the language/platform that runs on almost all devices. Only C can beat that.

Re: [Pharo-dev] [Nautilus] How to copy a method from a class to another class ?

by kilon alios

ok dont look at it, apparently it was not that either, I passed an array to a method that expected a single object so it was my bad. Sorry to bother you I will take a thorough look and test it further to make sure it works 100% . For now it looks like it copy pastes work just fine. I tried to copy paste a single method it has done so without any issues. I was thinking adding Paste new... to offer the user the option to paste the method but with a different name. Hows that sounds ?

Re: [Pharo-dev] [Nautilus] How to copy a method from a class to another class ?

by kilon alios

I don't think its confusing , what I am doing is store self selectedMethods to methodsToBeCopied instance variable. I choose this approach for when you dont remember the name of the class or why do that extra dialog step when you can just simple paste it ? I see an issue with my code though I think it may cause a problem if I open another instance of nautilus window then that instance variable value wont exist for that instance so apparently I am doing it wrong and I will need to move this to class side. Maybe thats the reason for DNU. Dont worry I am not in a hurry, apparently I need to look into this.

Re: [Pharo-dev] Voronoi diagram

by Emilio Oca

Hi My thesis (10 years ago) was about Voronoi and its use for path planning on robot soccer. I think that the most interesting part was the visualization (and testing) tool built to see the construction of the graph by following the front wave in a continuous way by dragging the mouse over the field. Part of the thesis was to extend the building algorithm to consider the sides of the field as non punctual obstacles. I think it was nice to see it work :) but the code may be not as nice nowadays. Let me know if you think it may be useful. Best!

Re: [Pharo-dev] [Nautilus] How to copy a method from a class to another class ?

by Benjamin

The copy/paste mechanism is always a bit confusing since you often do not know what is in the clipboard (even if people are use to it, I often see people copying a line, then retype it because they forgot it was here etc) Why not a âmoveâ like popup where you choose directly the destination ?
