+/*
+ * KButtonBox class
+ *
+ * A container widget for buttons. Uses Qt layout control to place the
+ * buttons, can handle both vertical and horizontal button placement.
+*
+ * HISTORY
+ *
+ * 05/11/2004 Andrew Coles <andrew_coles@yahoo.co.uk>
+ * Now uses QPtrListIterators instead of indexing through data->buttons
+ * Item.button and data are now const pointers, set in the relevant constructors
+ *
+ * 03/08/2000 Mario Weilguni <mweilguni@kde.org>
+ * Removed all those long outdated Motif stuff
+ * Improved and clarified some if conditions (easier to understand)
+ *
+ * 11/13/98 Reginald Stadlbauer <reggie@kde.org>
+ * Now in Qt 1.4x motif default buttons have no extra width/height anymore.
+ * So the KButtonBox doesn't add this width/height to default buttons anymore
+ * which makes the buttons look better.
+ *
+ * 01/17/98 Mario Weilguni <mweilguni@sime.com>
+ * Fixed a bug in tqsizeHint()
+ * Improved the handling of Motif default buttons
+ *
+ * 01/09/98 Mario Weilguni <mweilguni@sime.com>
+ * The last button was to far right away from the right/bottom border.
+ * Fixed this. Removed old code. Buttons get now a minimum width.
+ * Programmer may now override minimum width and height of a button.
