\class TQGroupBox ntqgroupbox.h
\brief The TQGroupBox widget provides a group box frame with a title.
\ingroup organizers
\ingroup geomanagement
\ingroup appearance
\mainclass
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().
TQGroupBox 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().
