Usage

The text attribute defines the label to be displayed near the check box.

The box shows a checkmark when the form field contains the value defined in the valueChecked attribute (for example: "Y"), and shows no checkmark if the field value is equal to the value defined by the valueUnchecked attribute (for example: "N"). If you do not specify the valueChecked or valueUnchecked attributes, they respectively default to TRUE (integer 1) and FALSE(integer 0).

By default, during an INPUT, a CheckBox field can have three states:

If the field is declared as notNull, the initial state can be grayed if the default value is NULL; once the user has changed the state of the CheckBox field, it switches only between checked and unchecked states.

During an CONSTRUCT, a CheckBox field always has three possible states (even if the field is notNull), to let the user clear the search condition:
