API GetChannelDisplayInfo

Retrieves channels (and category headers) that would be displayed in Blizzards ChannelFrame.

name, header, collapsed, channelNumber, count, active, category, voiceEnabled, voiceActive = GetChannelDisplayInfo(i);

Arguments

 * id: item id (ChannelFrame can display a combined maximum of 20 channels and headers; see MAX_CHANNEL_BUTTONS and use API GetNumDisplayChannels)

Returns

 * name: (for channels) channel name (for headers) name of the header
 * header: true if this item is a header (e.g. for category "CHANNEL_CATEGORY_WORLD")
 * collapsed: (for headers) true if subchannels are hidden (header is collapsed)
 * channelNumber: (for channels) channel number
 * count: (for channels) number of players in this channel (for headers) number of subchannels beneath this header
 * active: (for channels) true if channel is active (if you leave a city where you were in Trade Channel the channel will remain as inactive)
 * category: (for channels) "CHANNEL_CATEGORY_WORLD", "CHANNEL_CATEGORY_GROUP" or "CHANNEL_CATEGORY_CUSTOM"
 * voiceEnabled: true if voice is enabled for this channel
 * voiceActive : true if voice is currently active (someone is speaking)


 * Note

I didn't test this function in detail. But it looks very powerful and could help keeping an eye on joined channels. Just look into ChannelFrame.lua for more information.
