API GetChannelDisplayInfo

Returns info for chat channels and headers in the Chat Pane. name, header, collapsed, channelNumber, count, active, category, voiceEnabled, voiceActive = GetChannelDisplayInfo(i)

• id:item id, an integer between 1 and GetNumDisplayChannels (ChannelFrame can display a combined maximum of 20 channels and headers; see MAX_CHANNEL_BUTTONS and use API GetNumDisplayChannels)

• 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.
