UI Lua API import (WAR 1.4.8)

New page

{{LuaApi|group=Auction}}
Asks the server to cancel one of the player's own auction listings.

<pre>
CancelAuction(auctionIdHigh, auctionIdLow, revision)
</pre>

== Arguments ==
;auctionIdHigh : <code>number</code> – High part of the auction id (<code>auctionIDHigherNum</code> in the stock search results).
;auctionIdLow : <code>number</code> – Low part of the auction id (<code>auctionIDLowerNum</code>).
;revision : <code>number</code> – Revision number of the listing (<code>revision</code>).

== Returns ==
Nothing.

== Details ==
* Sends the same request as [[API:BuyAuction|BuyAuction]], with a price of 0 and the cancel marker set.
* There is no confirmation in the client. The stock UI shows a Yes/No dialog first.
* Whether the cancel is allowed is decided by the server.
* The function needs at least three arguments and only reads the last three.

== Errors ==
None besides the generic ''Invalid Parameters'' message when an argument is not a number.

== Example ==
The Yes callback of the stock cancel dialog, from <code>default/ea_auctionhousewindow/source/auctionwindow.lua</code>:
<pre>
function AuctionWindow.CancelPressConfirmed()
local windowData = AuctionWindowListDataManager.GetCurrentWindowData()
local auctionData = windowData.searchResultsData[windowData.currentlySelectedRow]

if( auctionData == nil )
then
return
end

CancelAuction( auctionData.auctionIDHigherNum, auctionData.auctionIDLowerNum, auctionData.revision )
end
</pre>

* [[API:BuyAuction|BuyAuction]]
* [[API:CreateAuction|CreateAuction]]
