'''This module implements the UI items found in the libgimpui library.
|
|
It requires pygtk to work. These functions take use to callbacks -- one
|
|
is a constraint function, and the other is the callback object. The
|
|
constraint function takes an image object as its first argument, and
|
|
a drawable object as its second if appropriate. The callback functions
|
|
get the selected object as their first argument, and the user data as
|
|
the second.
|
|
|
|
It also implements a number of selector widgets, which can be used to select
|
|
various gimp data types. Each of these selectors takes default as an argument
|
|
to the constructor, and has a get_value() method for retrieving the result.
