~~Title: Check Box Properties ~~
<pageheader/>

The specific properties applicable to the //Check Box// control are:

  * **Tri-state**: Set to **True** to give this check box a third state, “indeterminate”. This third state appears to the user as a solid rectangle inside the checkbox ( {{:media:image126.png?nolink|}} ). If set to **False** the check box will have only two states, //on// and //off//.
  * **Check State**: Use this to control the default state of the check box. The state can also be changed programmatically by your script.
