combohelperdialog.h

/*
 * combohelperdialog.h
 *
 * The ComboHelperDialog class is used to create a pop-up
 * dialog that lets the user choose a certain sum and a
 * certain number of numbers, and then displays the
 * possible combinations for that "sum" in "num."
 * There are two QComboBoxes (for choosing "sum"
 * and "num"), and a QPlainTextEdit to show the combinations.
 *
 * A pointer to a PuzzleBoard is present so that on construction,
 * we can copy the data from the PuzzleBoards sumInNumCombo[SUM][NUM]
 * into ours. After the copy, the pointer is not used.
