wx:snip-class%

Superclass: wx:object%

is uninteresting. Useful snip classes are defined by instantiating derived subclasses of wx:snip-class%. A class derived from wx:snip-class% serves as a kind of ``meta-class'' for snips; each snip is then associated with an instance of wx:snip-class% as its snip class.

In deriving a new snip class class (sic):

• Override the read method.

Then, for each instance of the derived class (where each instance corresponds to a single snip class):

• Set the classname using set-classname.
• Set the version using set-version.
• Install the class into the list returned by using the addmethod. Note that if the same name is inserted into the same class list mulitple times, all but the first insertion is ignored.

See also Snip Classes.

• (make-object wx:snip-class%) -> wx:snip-class% object

  Creates a useless snip class.
