Editing Visible

Specifies whether an object can be seen or is hidden.Syntax:
 set the [effective] visible of <nowiki><object></nowiki> to {true | false}

Examples:
 set the visible of stack "Palette" to false

 set the visible of me to (not the visible of me)

 put the effective visible of button "save"

Use the [[visible]] property to determine whether an object
is hidden or not, or to hide or show an object.

A hidden object is still present and still takes up memory, and a
handler can access its properties and contents, but the user cannot see
or or interact with it.

An object that cannot be seen only because it's behind another object is
still visible, in the sense that its [[visible]] [[property]] is still true.

The [[visible]] property of grouped controls is
independent of the [[visible]] property of the group. Setting
a group's [[visible]] property to false doesn't change
the [[visible]] property of its controls; their [[visible]]
[[property]] is still true, even though the controls cannot be
seen because the group is invisible.

If you specify the effective keyword the visible property of a control
returns true if, and only if, the control and all it's parent groups are
visible. 

You can set the [[visible]] property of a card, but doing so
has no effect. Cards cannot be made invisible.

The [[visible]] property is the logical inverse of the [[invisible]]
property. When an object's [[visible]] is true, its [[invisible]]
is false, and vice versa.
