<p>UI Lua API import (WAR 1.4.8)</p> <p><b>New page</b></p><div>{{LuaApi|group=ActionButtonGroup}}<br /> Shows or hides one button of an ActionButtonGroup.<br /> <br /> &lt;pre&gt;<br /> ActionButtonGroupSetShowing(groupName, buttonIndex, show)<br /> &lt;/pre&gt;<br /> <br /> == Arguments ==<br /> ;groupName : &lt;code&gt;string&lt;/code&gt; – Name of an ActionButtonGroup window.<br /> ;buttonIndex : &lt;code&gt;number&lt;/code&gt; – Button number, starting at 1. Fractions are dropped.<br /> ;show : &lt;code&gt;boolean&lt;/code&gt; – &lt;code&gt;true&lt;/code&gt; to show the button, &lt;code&gt;false&lt;/code&gt; to hide it.<br /> <br /> == Returns ==<br /> Nothing.<br /> <br /> == Details ==<br /> * The button&#039;s showing flag is set and the client updates the group&#039;s drawing data for that button. [[API:ActionButtonGroupGetShowing|ActionButtonGroupGetShowing]] reads the flag back.<br /> * &lt;code&gt;buttonIndex&lt;/code&gt; must be between 1 and the number of buttons; otherwise the &#039;&#039;not a valid ButtonIndex&#039;&#039; error is logged.<br /> * &lt;code&gt;show&lt;/code&gt; must be a real boolean. Passing &lt;code&gt;nil&lt;/code&gt; or a number raises an &#039;&#039;Invalid Parameters&#039;&#039; error. The stock UI passes a comparison such as &lt;code&gt;careerLineId ~= nil&lt;/code&gt;.<br /> * The &#039;&#039;No window specified&#039;&#039; error exists in the client but cannot be raised: a missing name is replaced by an empty string first, which gives the &#039;&#039;does not exist&#039;&#039; error.<br /> * The function needs at least three arguments and only reads the last three.<br /> <br /> == Errors ==<br /> These are written to the UI log; the call returns normally.<br /> * &lt;code&gt;Error in function call &#039;ActionButtonGroupSetShowing&#039;: Window %s does not exist.&lt;/code&gt;<br /> * &lt;code&gt;Error in function call &#039;ActionButtonGroupSetShowing&#039;: Window %s is not a ActionButtonGroup&lt;/code&gt;<br /> * &lt;code&gt;Error in function call &#039;ActionButtonGroupSetShowing&#039;: &#039;%d&#039; is not a valid ButtonIndex. (NumButtons = &#039;%d&#039;)&lt;/code&gt;<br /> * &lt;code&gt;Error in function call &#039;ActionButtonGroupSetShowing&#039;: No window specified.&lt;/code&gt; (never raised, see above)<br /> <br /> == Example ==<br /> From &lt;code&gt;ea_uimodwindow/source/uimodwindow.lua&lt;/code&gt;:<br /> &lt;pre&gt;<br /> ActionButtonGroupSetShowing( windowName..&quot;ScrollChildCareers&quot;, index, careerLineId ~= nil )<br /> &lt;/pre&gt;<br /> <br /> == See also ==<br /> * [[API:ActionButtonGroupGetShowing|ActionButtonGroupGetShowing]]<br /> * [[API:ActionButtonGroupSetNumButtons|ActionButtonGroupSetNumButtons]]<br /> * [[API:ActionButtonGroupSetId|ActionButtonGroupSetId]]</div>
