[Vala] Any tips for newbies

[Robin Wils <mrwils protonmail com>]

Dear Vala mailing list readers,

I am working on a [small simple project](https://gitlab.com/RobinWils/BAG-art-creator/tree/master) and have a 
feeling that the GNOME Vala website only contains some basics. One of my issues is that I haven't found a way 
to recreate a object.

I use a grid which I want to be able to resize when a menu_button gets clicked so I probably need a way to 
recreate/refresh the grid.

I was wondering of there are any other useful sites or tips for new Vala users. I am probably already doing 
some bad practises in that project since I am new to the Vala language.

Regards,
Robin Wils
