Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Wrapping Widgets with Vertical Box inside Scroll Box doesn't work?

Does anyone know why placing widgets inside vertical boxes that are inside scoll boxes doesn't work? Placing the widgets directly in the scroll box works but once you wrap them in a vertical box it stops working. Can this not been done with Vertical Box (do I need to use something else?)

I want to be able to collapse the Vertical Box to hide a set amount of embedded Widgets.

Placing other widgets inside a Vertical Box that is inside a Scroll Box doesn't seem to work. Placing the widgets directly inside the Scroll Box works, but I want to be able to collapse groups of the widgets during gameplay. There has been a few other posts about this in the past but it has never been answered.

can i see the result your getting cause off hand i think i can get it to work but are the widgets the same size or all different?

There is no result, adding the Vertical Box to the Scroll Box and then adding in Widgets (all the same size) simply shows nothing when run. If I place the same widgets inside the scroll box it works fine, but then I can't collapse groups of them.
