Action list

You can direct the installer to perform actions before a page is shown by using a <preShowPageActionList> section. The following example presents the user with information that stored in a registry key under Windows and in an environment variable under Linux.

     <infoParameter>
       <preShowPageActionList>
         <registryGet>
        <variable>some_info</variable>
            <key>HKEY_LOCAL_MACHINE\SOFTWARE</key>
           <name>MYAPP</name>
           <ruleList>
             <compareText>
              <text>${platform_name}</text>
              <logic>equals</logic>
              <value>windows</value>
             </compareText>
           </ruleList>
        </registryGet>
        <setInstallerVariable>
          <name>some_info</name>
          <value>${env(SOMEINFO)}</value>
          <ruleList>
             <compareText>
              <text>${platform_name}</text>
              <logic>equals</logic>
              <value>linux</value>
             </compareText>
          </ruleList>
         </setInstallerVariable>
       </preShowPageActionList>
       <name>display_info</name>
       <title>License File Information</title>
       <explanation>This screen shows important information \r about licensing issues</explanation>
       <value>Important Information! Setup has detected \r the following : ${some_info}.
In the following screen you \r will be asked to confirm the information or enter a new (...)</value>


     </infoParameter>
