Example 2 with PickerComponent

use of com.codename1.ui.PickerComponent in project CodenameOne by codenameone.

the class Validator method addConstraint.

/**
 * Places a constraint on the validator, returns this object so constraint
 * additions can be chained. Shows validation errors messages even when the
 * TextModeLayout is not {@code onTopMode} (it's possible to disable this
 * functionality setting to false the theme constant
 * {@code showValidationErrorsIfNotOnTopMode}: basically, the error
 * message is shown for two second in place of the label on the left of the
 * InputComponent (or on right of the InputComponent for RTL languages);
 * this solution never breaks the layout, because the error message is
 * trimmed to fit the available space. The error message UIID is
 * "ErrorLabel" when it's not onTopMode.
 *
 * @param cmp the component to validate
 * @param c the constraint or constraints
 * @return this object so we can write code like v.addConstraint(cmp1,
 * cons).addConstraint(cmp2, otherConstraint);
