Checkbox UI Control

Creating User Interfaces - Quick Navigation

A checkbox control is used to place a check box on the rollout. The user can click to successively switch between states.

The syntax is:

checkbox <name> [<caption>] [checked:<boolean>] [triState:<integer>][tooltip:<string>] 	 

The default alignment of checkbox items is #left .

Parameters:

checked:   

Initial state of the check box, defaults to false (unchecked).

triState: 

An integer value controlling the checked state of the checkbox as follows:

0 - unchecked (checked:false)

1 - checked (checked:true)

2 - indeterminate (checked:true)

When set to 2 (indeterminate), the checkbox will be displayed as greyed out and checked at the same time. Note that triState : has a higher priority than checked : which means that if you set the parameter checked : to false and the parameter triState : to 2 , the . checked property will return true . The checked : parameter / property remains <boolean> for backwards compatibility.

Clicking an indeterminate checkbox changes its state to unchecked.

tooltip: 

A string defining the tooltip to be displayed when the mouse rolls over the checkbox. Available in 3ds Max 2009 and higher.

Properties:

<checkbox>.checked Boolean 

The state of the check box, on ( true ) or off ( false ).
