Hi

Inserting an item with several columns into a ListCtrl:

def add\_items(items)  
i = 0  
items.each do |data|  
self.insert\_item(i, data[0])  
self.set\_item(i,1,data[1])  
self.set\_item(i,2,data[2])  
i += 1  
end  
end  
end

works fine but I am unable to set the background colour of the item:

self.set\_item\_background\_colour(i,RED)

gives: undefined method: set\_item\_background\_colour

Version is 1.9.4-i386-mswin32

Ideas?

Refreshing that the Scottish heritage of wxWidgets influences spelling:  
I am so used to color as opposed to colour.

I can only assume that ListCtrl#set\_item\_background\_colour is not  
supported by MSW so I have used ListItem#set\_background\_colour  
successfully instead.

Missed your earlier message. From the wxWidgets headers it looks like  
set\_item\_background\_colour should be supported on MSW, Mac and generic,  
but it’s missing currently from wxRuby. We can add it for the next  
release.

Thanks for the report.
