25  * \class KScoreDialog kscoredialog.h <KScoreDialog>
26  *
27  * @short A simple high score implementation
28  *
29  * This class can be used both for displaying the current high scores
30  * and also for adding new highscores. It is the recommended way of
31  * implementing a simple highscore table.
32  *
33  * To display the current highscores it is simply a case of creating
34  * a KScoreDialog object and calling exec(). This example code will
35  * display the Name and Score (the score is always added automatically
36  * unless hidden @ref hideField since it is used for sorting) of the
37  * top 10 players:
38  * \code
39  * KScoreDialog ksdialog(this);
40  * ksdialog.exec();
41  * \endcode
42  *
43  * To add a new highscore, e.g. at the end of a game you simply create an
44  * object with the @ref Fields you want to write (i.e. KScoreDialog::Name |
45  * KScoreDialog::Score), call addScore and then (optionally) display
46  * the dialog.
47  * This code will allow you to add a highscore with a Name and Score
48  * field. If it's the first time a player has a score on the table, they
49  * will be prompted for their name but subsequent times they will have
50  * their name filled in automatically.
51  * \code
52  * KScoreDialog ksdialog(this);
53  * ksdialog.addScore(playersScore);
54  * ksdialog.exec();
55  * \endcode
56  *
57  * Or if you want to fill the name in from the code you can pass a default
58  * name by doing
59  * \code
60  * KScoreDialog::FieldInfo scoreInfo;
61  * scoreInfo[KScoreDialog::Name] = "Matt";
62  * scoreInfo[KScoreDialog::Score].setNum(playersScore);
63  * ksdialog.addScore(scoreInfo);
64  * \endcode
65  *
66  * If you want to add an extra field (e.g. the number of moves taken) then
67  * do
68  * \code
69  * KScoreDialog::FieldInfo scoreInfo;
70  * scoreInfo[KScoreDialog::Name] = "Matt";
71  * scoreInfo[KScoreDialog::Score].setNum(playersScore);
72  *
73  * ksdialog.addField(KScoreDialog::Custom1, "Num of Moves", "moves");
74  * scoreInfo[KScoreDialog::Custom1].setNum(42);
75  *
76  * ksdialog.addScore(scoreInfo);
77  * \endcode
78  * You can define up to 5 Custom fields.
