+ \class Q3GroupBox
+ \brief The Q3GroupBox widget provides a group box frame with a title.
+
+ \compat
+
+ A group box provides a frame, a title and a keyboard shortcut, and
+ displays various other widgets inside itself. The title is on top,
+ the keyboard shortcut moves keyboard focus to one of the group
+ box's child widgets, and the child widgets are usually laid out
+ horizontally (or vertically) inside the frame.
+
+ The simplest way to use it is to create a group box with the
+ desired number of columns (or rows) and orientation, and then just
+ create widgets with the group box as parent.
+
+ It is also possible to change the orientation() and number of
+ columns() after construction, or to ignore all the automatic
+ layout support and manage the layout yourself. You can add 'empty'
+ spaces to the group box with addSpace().
+
+ Q3GroupBox also lets you set the title() (normally set in the
+ constructor) and the title's alignment().
+
+ You can change the spacing used by the group box with
+ setInsideMargin() and setInsideSpacing(). To minimize space
+ consumption, you can remove the right, left and bottom edges of
+ the frame with setFlat().
