Returns whether one button of an ActionButtonGroup is set to be shown.<br />
<br />
<pre><br />
showing = ActionButtonGroupGetShowing(groupName, buttonIndex)<br />
</pre><br />
<br />
== Arguments ==<br />
;groupName : <code>string</code> – Name of an ActionButtonGroup window.<br />
;buttonIndex : <code>number</code> – Button number, starting at 1. Fractions are dropped.<br />
<br />
== Returns ==<br />
;showing : <code>boolean</code> – The button's showing flag, as set by [[API:ActionButtonGroupSetShowing|ActionButtonGroupSetShowing]].<br />
<br />
== Details ==<br />
* Only the button's own flag is read. Whether the group window itself is showing is not checked.<br />
* <code>buttonIndex</code> must be between 1 and the number of buttons; otherwise the ''not a valid ButtonIndex'' error is logged and nothing is returned.<br />
* If the window does not exist or is not an ActionButtonGroup, the error is logged and nothing is returned.<br />
* The ''No window specified'' error exists in the client but cannot be raised: a missing name is replaced by an empty string first, which gives the ''does not exist'' error.<br />
* The function needs at least two arguments and only reads the last two.<br />
* The stock UI never calls <code>ActionButtonGroupGetShowing</code>.<br />
<br />
== Errors ==<br />
These are written to the UI log; the call returns normally.<br />
* <code>Error in function call 'ActionButtonGroupGetShowing': Window %s does not exist.</code><br />
* <code>Error in function call 'ActionButtonGroupGetShowing': Window %s is not a ActionButtonGroup</code><br />
* <code>Error in function call 'ActionButtonGroupGetShowing': '%d' is not a valid ButtonIndex. (NumButtons = '%d')</code><br />
* <code>Error in function call 'ActionButtonGroupGetShowing': No window specified.</code> (never raised, see above)<br />
<br />
== Example ==<br />
A minimal example built from the signature above:<br />
<pre><br />
if( ActionButtonGroupGetShowing( "MyButtonGroup", 2 ) ) then<br />
ActionButtonGroupSetShowing( "MyButtonGroup", 2, false )<br />
end<br />
</pre><br />
