/**
 * @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
 *
 * 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.
 *
 * By default, the dialog is non-modal.
 *
 * <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 emit a signal, so you can choose to connect that signal.
 *
 * The default action of the Help button will open the help system if you have
 * provided a path to the help text.
 * The default action of Ok and Cancel will run QDialog::accept() and QDialog::reject(),
 * which you can override by reimplementing slotButtonClicked(). The default
 * action of the Close button will close the dialog.
 *
 * Note that the KDialog will animate a button press
 * when the user presses Escape. The button that is enabled is either Cancel,
 * Close or the button that is defined by setEscapeButton().
 * Your custom dialog code should reimplement the keyPressEvent and
 * animate the cancel button so that the dialog behaves like regular
 * dialogs.
 *
 * <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
 * setButtonsOrientation() 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).
 *
 * <b>Standard compliance:</b>\n
 *
 * The marginHint() and spacingHint() sizes shall be used
 * whenever you lay out the interior of a dialog. One special note. If
 * you make your own action buttons (OK, Cancel etc), the space
 * between the buttons shall be spacingHint(), whereas the space
 * above, below, to the right and to the left shall be marginHint().
 * If you add a separator line above the buttons, there shall be a
 * marginHint() between the buttons and the separator and a
 * marginHint() above the separator as well.
 *
 * <b>Example:</b>\n
 *
 * \code
 *   KDialog *dialog = new KDialog( this );
 *   dialog->setCaption( "My title" );
 *   dialog->setButtons( KDialog::Ok | KDialog::Cancel | KDialog::Apply );
 *
 *   FooWidget *widget = new FooWidget( dialog );
 *   dialog->setMainWidget( widget );
 *   connect( dialog, SIGNAL( applyClicked() ), widget, SLOT( save() ) );
 *   connect( dialog, SIGNAL( okClicked() ), widget, SLOT( save() ) );
 *   connect( widget, SIGNAL( changed( bool ) ), dialog, SLOT( enableButtonApply( bool ) ) );
 *
 *   dialog->enableButtonApply( false );
 *   dialog->show();
 * \endcode
 *
 * \image html kdialog.png "KDE Dialog example"
 *
 * This class can be used in many ways. Note that most KDE ui widgets
 * and many of KDE core applications use the KDialog so for more
 * inspiration you should study the code for these.
