Hi everyone, I am new to this mailing list and to Smalltalk too. If I've made something wrong using this mailing list, please just tell me what I have to do. I am currently making a graphical development tool in Pharo 2.0 (I sadly can't go on more recent versions because I'm adding my tool to an existing Pharo image). I discovered Roassal last week and I decided to use it combined with a Glamour GUI. I'm currently stuck with ROInteractions. I would like to add drag&drop interaction to my ROElements with conditions like we can do with morphs (a ROElement A can be dropped on another one B if A is accepted by B). Is there an equivalent in Roassal? I've seen some ROMorph but I found no documentation about them. Is it a good idea to use them and if yes, where can I find some tutorials to start with? Best regards, Frédéric VERDIER.
