[Vtigercrm-developers] Creating a custom UIType?

[Alan Lord]

A canvas field could be useful for many things - I have a specific 
use-case here which I do not want to go into but the requirement may be 
applicable across multiple modules... I'm not sure that Reports will be 
an issue though - why would you want to report _anything_ about a canvas 
field?

Anyway - creating a new UIType and registering it in the 
vtiger_ws_fieldtype table appears to be working. I've created a 
Canvas.php Field Model and a couple of tpl files for Detail and Edit views.

It's a shame that all this can't be kept in a custom module though (or 
outside the standard module structures) - for now it will have to remain 
in the Vtiger module structure. Hence why I suggested adding a top-level 
"custom" directory to Vtiger [1]
