Overview of Item Types

Pad Items

Each pad widget implicitly defines a special "pad" item which always has the id "1". This is a special item which can get events and has a few itemconfigure options. It may not be explicitly created or deleted. The valid options are:

[58] -visiblelayers layers

(available only for pad and portal item types)
Specifies what layers are visible within this portal. layers can be either a list of layers which will specify which items will be displayed within this portal, or take the special form of "all -layer1 -layer2 -layer3 ..." in which case all layers except the ones specified will be displayed. Defaults to "all". (See the -layer itemconfigure option that all items have.)
