Querying a selection box is one way to find out and respond to its state.

Radio buttons have two states: checked (BF_CHECKED) and unchecked (BF_UNCHECKED). Check boxes can have an additional (and optional) third state: grayed (BF_GRAYED). The following table summarizes the selection-box query member functions.
