Constructor Detail

ChoiceGroup

public ChoiceGroup(java.lang.String label,
                   int choiceType)

ChoiceGroup

public ChoiceGroup(java.lang.String label,
                   int choiceType,
                   java.lang.String[] stringElements,

Method Detail

append

public int append(java.lang.String stringPart,
                  Image imagePart)

Specified by:

append in interface Choice

---

delete

public void delete(int itemNum)

Specified by:

delete in interface Choice

---

getImage

public Image getImage(int elementNum)

Specified by:

getImage in interface Choice

---

getSelectedFlags

public int getSelectedFlags(boolean[] selectedArray_return)

Queries the state of a ChoiceGroup and returns the state of all elements in the boolean array selectedArray_return. NOTE: this is a result parameter. It must be at least as long as the size of the ChoiceGroup as returned by size(). If the array is longer, the extra elements are set to false. For ChoiceGroup objects of type MULTIPLE, any number of elements may be selected and set to true in the result array. For ChoiceGroup objects of type EXCLUSIVE, exactly one element will be selected, unless there are zero elements in the ChoiceGroup.

Specified by:

getSelectedFlags in interface Choice

---

getSelectedIndex

public int getSelectedIndex()

Returns the index number of an element in the ChoiceGroup that is selected. For ChoiceGroup objects of type EXCLUSIVE there is at most one element selected, so this method is useful for determining the user's choice. Returns -1 if there are no elements in the ChoiceGroup. For ChoiceGroup objects of type MULTIPLE, this always returns -1 because no single value can in general represent the state of such a ChoiceGroup. To get the complete state of a MULTIPLE Choice, see getSelectedFlags.

Specified by:

getSelectedIndex in interface Choice
