    Hi Folks,<br>
    <br>
    Nicola, you are right. #visible and #visible: are only about the
    property.<br>
    <br>
    Hilaire, right now we have #isInWorld . Perhaps we could add
    #isVisible, or #isInWorldAndVisible, that asks for both conditions.<br>
    <br>
    Thanks,<br>
    <br>

        <br>
        this is not my kingdom so wait other people suggestions but<br>
        browsing around i think "visible" is for you to set an object<br>
        visible or not, as in:<br>
        <br>
        -----<br>
        tmp2 _ BoxedMorph new. <br>
        tmp2 openInWorld . <br>
        <br>
        tmp2 visible: false. <br>
        tmp2 visible. <br>
        tmp2 visible: true. <br>
        -----<br>
        <br>
        If you want to check if 'aMorph' is gone paradise you may use (i
        see it<br>
        from the explorer) the 'owner' message. If 'owner' is nil then<br>
        either the morph is a World or it is gone.<br>
        ... this supposing 'aMorph' has still not been garbadge
        collected.<br>
        <br>
