Hi.

> How to make a canvas widget to be transparent?

You can either set INHERIT_FORCE as the *parents* background mode[1], or
you can give the Canvas a custom variant[2] and add[3] a CSS rule for
*Composite* like this to your RWT theme:

Composite.yourCustomVariant {
background-color: transparent;
}

Greetings,
Tim
