Java Code Examples for com.codename1.ui.Form#getName()

/**
 * Returns the state of the current form which we are about to leave as part
 * of the navigation logic. When a back command will return to this form the
 * state would be restored using setFormState.
 * The default implementation of this method restores focus and list selection.
 * You can add arbitrary keys to the form state, keys starting with a $ sign
 * are reserved for the UIBuilder base class use.
 *
 * @param f the form whose state should be preserved
 * @return arbitrary state object
