Can you pass in a space-separated string, such as '' or 'token1' or 'token1 token2'?
No I tried that.
* I can't pass a default value to a boolean property. How to?
How are you trying to do this? You can pass in the string '1' for true and '0' for false.
I tried both int numbers 0/1 and strings '0'/'1'
Could someone please give me some example code or hints?
It would really help to see some of the code you're already using. Can you also say a bit about what you are trying to do overall?
I'm currently trying to create a ZBibliography product. Every class should have a base class which defines the basic properties in two property sheets 'data' and description'. For example: the 'data' property sheet currently stores 'persons', and 'title' while the 'description' sheet stores for example 'languages' (tokens), 'offprint', and 'public' boolean attributes. I'm not shure if this works: I wanna extend the properties stored in the 'data' sheet in the subclasses 'book', 'article', etc. Please be patient because this is my first python program. I hope this helps Eric --- Here are parts of my code: Properties for the 'desc' PropertySheet self._descprops = ( {'id':'source', 'type':'string', 'value':'', 'mode':'w',}, {'id':'languages', 'type':'tokens', 'value':'en', 'mode':'w',}, {'id':'files', 'type':'lines', 'value':'', 'mode':'w',}, {'id':'keywords', 'type':'lines', 'value':'', 'mode':'w',}, {'id':'references', 'type':'lines', 'value':'', 'mode':'w',}, {'id':'abstracts', 'type':'text', 'value':'', 'mode':'w',}, {'id':'annotation', 'type':'text', 'value':'', 'mode':'w',}, {'id':'classification', 'mode':'w', 'type':'multiple selection', 'value':'', 'select_variable':'categories', 'mode':'w',}, {'id':'offprint', 'type':'boolean', 'value':0, 'mode':'w',}, {'id':'public', 'type':'boolean', 'value':1, 'mode':'w',}, ) Properties for the 'data' PropertySheet: self._dataprops = ( {'id':'persons', 'value':'', 'type':'lines', 'mode':'w'}, {'id':'title', 'value':title, 'type':'string', 'mode':'w'}, {'id':'title_transl', 'value':'', 'type':'string', 'mode':'w'}, )
