/**
 * @short A dialog base class with standard buttons and predefined layouts.
 *
 * Provides basic functionality needed by nearly all dialogs.
 *
 * It offers the standard action buttons you'd expect to find in a
 * dialog as well as the capability to define at most three configurable
 * buttons. You can define a main widget that contains your specific
 * dialog layout or you can use a predefined layout. Currently, @p
 * TreeList/Paged, @p Tabbed, @p Plain, @p Swallow and @p IconList
 * mode layouts (faces) are available.
 *
 * The class takes care of the geometry management. You only need to define
 * a minimum size for the widget you want to use as the main widget.
 *
 * You can set a background tile (pixmap) for parts of the dialog. The
 * tile you select is shared by all instances of this class in your
 * application so that they all get the same look and feel.
 *
 * There is a tutorial available on http://developer.kde.org/ (NOT YET)
 * that contains
 * copy/paste examples as well a screenshots on how to use this class.
 *
 * <b>Standard buttons (action buttons):</b>\n
 *
 * You select which buttons should be displayed, but you do not choose the
 * order in which they are displayed. This ensures a standard interface in
 * KDE. The button order can be changed, but this ability is only available
 * for a central KDE control tool. The following buttons are available:
 * OK, Cancel/Close, Apply/Try, Default, Help and three user definable
 * buttons: User1, User2 and User3. You must specify the text of the UserN
 * buttons. Each button has a virtual slot so you can overload the method
 * when required. The default slots emit a signal as well, so you can choose
 * to connect a signal instead of overriding the slot.
 * The default implementation of slotHelp() will automatically enable
 * the help system if you have provided a path to the help text.
 * slotCancel() and slotClose() will run TQDialog::reject()
 * while slotOk() will run TQDialog::accept(). You define a default
 * button in the constructor.
 *
 * If you don't want any buttons at all because your dialog is special
 * in some way, then set the buttonMask argument in the constructor to zero
 * (0). The optional button box separator line should not be enabled
 * in this case. Note that the KDialogBase will animate a button press
 * when the user press Escape. The button that is enabled is either Cancel,
 * Close or the button that is defined by setEscapeButton() The
 * animation will not take place when the buttonMask is zero. Your
 * custom dialog code should reimplement the keyPressEvent and
 * animate the cancel button so that the dialog behaves like regular
 * dialogs. NOTE: None of the regular slots (like slotOk() ) or
 * signals that are related to the standard action buttons will be used
 * when you don't use these buttons.
 *
 * <b>Dialog shapes:</b>\n
 *
 * You can either use one of the prebuilt, easy to use, faces or
 * define your own main widget. The dialog provides ready to use
 * TreeList, Tabbed, Plain, Swallow and IconList faces. KDialogBase uses
 * the KJanusWidget class internally to accomplish this. If you
 * use TreeList, Tabbed or IconList mode, then add pages with addPage().
 *
 * Pages that have been added can be removed again by simply deleting
 * the page.
 *
 * If you want complete control of how the dialog contents should look,
 * then you can define a main widget by using setMainWidget(). You
 * only need to set the minimum size of that widget and the dialog will
 * resize itself to fit this minimum size.  The dialog is resizeable, but
 * cannot be made smaller than its minimum size.
 *
 * <b>Layout:</b>\n
 *
 * The dialog consists of a help area on top (becomes visible if you define
 * a help path and use enableLinkedHelp()), the main area which is
 * the built-in dialog face or your own widget in the middle and by default
 * a button box at the bottom. The button box can also be placed at the
 * right edge (to the right of the main widget). Use
 * setButtonBoxOrientation() to control this behavior. A separator
 * can be placed above the button box (or to the left when the button box
 * is at the right edge). Normally you specify that you want a separator
 * in the constructor, but you can use enableButtonSeparator() as well.
 *
 * <b>Standard compliance:</b>\n
 *
 * The class is derived from KDialog, so you get automatic access to
 * the KDialog::marginHint(), KDialog::spacingHint() and the
 * extended KDialog::setCaption() method. NOTE: The main widget you
 * use will be positioned inside the dialog using a margin (or border)
 * equal to KDialog::marginHint(). You should not add a margin yourself,
 * since one will be added automatically.
 * The example below (from kedit) shows how you use the top level widget
 * and its layout. The second argument (the border) to QVBoxLayout
 * is 0. This situation is valid for addPage , addVBoxPage ,
 * addHBoxPage , addGridPage , makeMainWidget ,
 * makeVBoxMainWidget , makeHBoxMainWidget and
 * makeGridMainWidget as well.
 *
 * Example:
 *
 * \code
 * UrlDlg::UrlDlg( TQWidget *parent, const TQString& caption,
 *                 const TQString& urltext)
 *   : KDialogBase( parent, "urldialog", true, caption, Ok|Cancel, Ok, true )
 * {
 *   TQWidget *page = new TQWidget( this );
 *   setMainWidget(page);
 *   TQVBoxLayout *topLayout = new TQVBoxLayout( page, 0, spacingHint() );
 *
 *   TQLabel *label = new TQLabel( caption, page, "caption" );
 *   topLayout->addWidget( label );
 *
 *   lineedit = new TQLineEdit( urltext, page, "lineedit" );
 *   lineedit->setMinimumWidth(fontMetrics().maxWidth()*20);
 *   topLayout->addWidget( lineedit );
 *
 *   topLayout->addStretch(10);
 * }
 * \endcode
 *
 * If you use makeVBoxMainWidget(), then the dialog above can be made
 * simpler but you lose the ability to add a stretchable area:
 *
 * \code
 * UrlDlg::UrlDlg( TQWidget *parent, const TQString& caption,
 *                 const TQString& urltext)
 * : KDialogBase( parent, "urldialog", true, caption, Ok|Cancel, Ok, true )
 * {
 *   TQVBox *page = makeVBoxMainWidget();
 *   TQLabel *label = new TQLabel( caption, page, "caption" );
 *
 *   lineedit = new TQLineEdit( urltext, page, "lineedit" );
 *   lineedit->setMinimumWidth(fontMetrics().maxWidth()*20);
 * }
 * \endcode
 *
 * This class can be used in many ways. Note that most KDE ui widgets
 * and many of KDE core applications use the KDialogBase so for more
 * inspiration you should study the code for these.
