/*! \class DVGui::Dialog

                \brief The Dialog class is the base class of dialog windows.

                Inherits \b QDialog.

                A dialog window is a top-level window, defined in \b QDialog,

this class provides

                a collection of functions to manage \b QDialog widget

visualization.

                Dialog window can be modal or modeless, from this it depends

dialog visualization.

                You set your dialog to modal or modeless directly in

constructor, with \b bool

                hasButton, in fact if the dialog has button then is modal too.

                If dialog is \b modal it's composed of two part, two \b QFrame;

the first, \b main

                \b part at top of dialog, contains a vertical box layout \b

QVBoxLayout, the second,

                \b button \b part at bottom, contains an horizontal box layout

\b QHBoxLayout.

                Else if dialog is modeless it is composed only of first part, to

be more precise,

                it is composed of a \b QFrame containing a vertical box layout

\b QVBoxLayout.

                The first part of dialog can be implemented using different

objects. You can manage

                directly vertical box layout, insert widget addWidget(), or

layout addLayout(), set

                border and spacing, using setTopMargin() and setTopSpacing(), or

insert a spece,

                addSpacing().

\n	If you need an horizontal layout you can use an implemented horizontal

box layout;

                the function beginHLayout() initialize the horizontal box

layout, a collection of

                function permit to insert object in this layout; at the end you

must recall

                endVLayout(), this add horizontal layout to first part of

dialog.

                This struct permit you to allign the object you insert.

\n	If you need vertical layout you can use an implemented vertical box

layout composed

                of two column, the function beginVLayout() initialize the

vertical box layout,

                a collection of function permit to insert object in this layout.

                All this functions insert a pair of object in two vertical

layout and permit

                to allign the objects, all pairs you insert are tabulated.

                At the end you must recall endVLayout(), this add vertical

layout to first part of

                dialog.

                The second part of dialog may be implemented if dialog is modal.

                It's possible insert one, two or three widget in its horizontal

box layout using

                addButtonBarWidget(), or clear all widget using

clearButtonBar(). You can also

                set margin and spacing with setButtonBarMargin() and

setButtonBarSpacing() functions.
