New page

{{LuaApi|group=ListBox}}
Changes how many row windows a ListBox has.

<pre>
ListBoxSetVisibleRowCount(listBoxName, rowCount)
</pre>

== Arguments ==
;listBoxName : <code>string</code> – Name of the ListBox.
;rowCount : <code>number</code> – New number of visible rows (converted to a whole number).

== Returns ==
Nothing.

== Details ==
* Row windows are created or destroyed so that the ListBox has <code>rowCount</code> rows, and the rows are refreshed from the data.
* If the count is already <code>rowCount</code>, nothing happens.
* The function needs at least two arguments and only reads the last two. Any extra arguments placed in front of them are ignored.

== Errors ==
* <code>Error in function call 'ListBoxSetVisibleRowCount': Incorrect parameters</code>
* <code>Error in function call 'ListBoxSetVisibleRowCount': Window %s does not exist</code>
* <code>Error in function call 'ListBoxSetVisibleRowCount': Window %s is not a ListBox</code>

== Example ==
Sizing two lists to their content, from <code>default/ea_interactionwindow/source/interactionbase.lua</code>:
<pre>
ListBoxSetVisibleRowCount("EA_Window_InteractionBaseQuestList", #questDisplayOrder)
ListBoxSetVisibleRowCount("EA_Window_InteractionBaseOptionList", #optionDisplayOrder)
</pre>
