+ \image html Fl_Check_Button.png
+ \image latex Fl_Check_Button.png "Fl_Check_Button" width=4cm
+ Buttons generate callbacks when they are clicked by the user. You control
+ exactly when and how by changing the values for type() and when().
+
+ The Fl_Check_Button subclass displays its "ON" state by showing a "checkmark"
+ rather than drawing itself pushed in.
+
+ \todo Refactor Fl_Check_Button doxygen comments (add color() info etc?)
+ \todo Generate Fl_Check_Button.gif with visible checkmark.
