Preventing the user from maximizing an application in Adobe AIR

In a previous example, “Preventing the user from minimizing an application in Adobe AIR”, we saw how you can disable the minimize button on a WindowedApplication container by editing the application’s XML file and set the <minimizable> node to false.

The following example shows how you can disable the maximize button on a WindowedApplication container by editing the application’s XML file and set the <maximizable> node to false. You can determine if the WindowedApplication is maximizable by using the read-only maximizable property.

Full code after the jump.

<?xml version="1.0" encoding="utf-8"?>
<!--  -->
<mx:WindowedApplication name="WindowedApplication_maximizable_test"
        xmlns:mx="http://www.adobe.com/2006/mxml"
        layout="vertical"
        verticalAlign="middle">
 
    <mx:Label text="maximizable: {application.maximizable}"
            fontSize="42" />
 
</mx:WindowedApplication>

And edit the application’s XML file and edit the following lines:

<!-- Whether the user can maximize the window. Optional. Default true. -->
<maximizable>false</maximizable>
