Paint Routine: Multiple rectangles by mouseaction

[toxonic]

I'm trying to build a sequencer with paint routine on a panel, and i'm at the very beginning.
Curently i'm trying to get multiple rectangles on the panel and i have no clue, how to do that.
In the following snippet, i can only create one rectangle at a time.
Any suggestions? Or maybe other ideas instead using paint routines?

@toxonic If you paint one rectangle it has to be stored somewhere so that it not will be erased when you paint the next.
You can store the value anywhere, in a slider pack or in the panel that you're using the paint routine...or ...

[Christoph Hart]

@ulrik The best way to store panel related data is either the panel.data object which is just a simple JSON object that can be populated or if you want to restore it automatically, the value slot itself (using getValue() / setValue()).

[ulrik]

@Christoph-Hart yes you're absolutely right, easier handling of restoring

[toxonic]

@Christoph-Hart @ulrik Thank you for your replies, i'll get thsi feature working, i guess. But i'm afraid, that a sequencer with basic functionality might be a huge task for someone with such little programming skills like me. For example, editing, moving and deleting existing notes - ino ideas, how i should be able to do this.
Maybe i shoul overthink this project again... :face_with_tears_of_joy:

@toxonic there's a recipe in the docs which can be useful for what to want to do (if I understood correctly what you want to do) :

@Matt_SF thank you man, this seems to be a good starting point! :-)
