I wondered whether you guys agree with me that examples could be useful in some extensions? With most extensions, you can create the desired result by trial-and-error (using the Live Preview function). However, other extensions aren't really self-explanatory (like the Lindenmayer System extension). Although there is a description how it can be used, most users won't understand what you can create with the extension. Therefore, I proposed to implement a list of examples (or a tab "Examples").

I would like to implement it myself, but I don't know where to start. I found some documentation about the INX files:
Maybe with a <script> environment, it would be possible to automatically assign appropriate values to the fields?

Hi all,

I'm currently working on an expansion of the L-System Extension (just for fun, getting to know XML and Python). I implemented an extra parameter "Factor", such that the fractal scales with each level. More info about this at the Inkscape Forums: http://www.inkscapeforum.com/viewtopic.php?f=5&t=6411

The thing is, I would like to include some examples in the extension. I thought of a drop-down menu (an "enum" type), with entries like "Koch Snowflake" and "Pythagoras Tree".

<param name="Examples" type="enum" _gui-text="Examples:">
   <item value="Koch_Snowflake">Koch Snowflake</item>
   <item value="Pythagoras_Tree">Pythagoras Tree</item>

When the user clicks on such an entry, appropriate values should be assigned to the fields (e.g. Axiom="F", Rules="F=F+F+F", Factor="0.5", etc.).
I wondered whether this is possible using XML, or the Relax NG schema language?

So to be clear, the GUI-part isn't a problem. The UI looks like this at the moment: http://www.redpanda.nl/ExamplesInkscape.png
However, the "auto-assign" function needs to be implemented yet.
