Roassal question : adding drop condition to ROElements in a visualization

 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.

No ask any question you want.

Really. Pharo2.0 is starting to get old. And with Pharo 30 you can have
access to athens (vector graphics)

Check if you cannot move the app to Pharo 30 :).

Alex will answer the questions.

have a look at deep into pharo, there are two chapters on Roassal and
Mondrian.

 The ROExample>>rubberBand is an awesome example to learn how to use
 ROSelection.

 I will try to use it.
