UI Lua API import (WAR 1.4.8)

New page

{{LuaApi|group=Window}}
Stores a number on a window as its id.

<pre>
WindowSetId(windowName, id)
</pre>

== Arguments ==
;windowName : <code>string</code> – Name of the window.
;id : <code>number</code> – The id to store.

== Returns ==
Nothing.

== Details ==
* The id is a free number for the UI's own use; the client only stores it. Read it back with [[API:WindowGetId|WindowGetId]].
* <code>id</code> is truncated towards zero to a whole number.
* There is no lock check in this function.
* The function needs at least two arguments and only reads the last two.

== Errors ==
* <code>Error in function call 'WindowSetId': Window %s does not exist</code>

== Example ==
From <code>easystem_dialogmanager/source/dialogmanager.lua</code>:
<pre>
local warningButton = "TwoButtonDlg"..dlg.."BoxNeverWarnButton";
-- ...
WindowSetId (warningButton, dlg + DialogManager.NEVER_WARN_ID_OFFSET);
</pre>

== See also ==
* [[API:WindowGetId|WindowGetId]]
