you pointed out, the listvariable has to be defined before the listbox will be created ... how is it possible to do define this variable in advance?

only said it should be unique. The -listvariable option creates the variable, if necessary.

never mind, i figured out that the _whole_ .wid file will be executed at startup ...

there are several blocks of .wid code, which are executed in a different context each:

1. Setup scriptlet is executed only once, right after the .wid

file has been read -- it is pushed to the pdgui layer by the constructor of the oldest object using the file. This part should be used for procedure definitions, etc.

2. Creator scriptlet (not handled yet by the released toxy

version) is executed once for every Pd [widget] object of the particular type -- it is pushed by the constructor of that object.

3. Initializing scriptlet is executed right after the Tk widget

has been created and configured, i.e. whenever an invisible Pd object receives the 'vis' message.

4. Each of the message handlers is pushed whenever an object

receives the corresponding message.

Currently, the structure of a .wid file is positional

<setup> <header> <creator> <properties (options, arguments, and handlers)> <initializer>
