137 \class QGroupBox-
138 \brief The QGroupBox widget provides a group box frame with a title.-
139-
140 \ingroup organizers-
141 \ingroup geomanagement-
142 \inmodule QtWidgets-
143-
144 A group box provides a frame, a title on top, a keyboard shortcut, and-
145 displays various other widgets inside itself. The keyboard shortcut moves-
146 keyboard focus to one of the group box's child widgets.-
147-
148 QGroupBox also lets you set the \l title (normally set in the-
149 constructor) and the title's \l alignment. Group boxes can be-
150 \l checkable. Child widgets in checkable group boxes are enabled or-
151 disabled depending on whether or not the group box is \l checked.-
152-
153 You can minimize the space consumption of a group box by enabling-
154 the \l flat property. In most \l{QStyle}{styles}, enabling this-
155 property results in the removal of the left, right and bottom-
156 edges of the frame.-
157-
158 QGroupBox doesn't automatically lay out the child widgets (which-
159 are often \l{QCheckBox}es or \l{QRadioButton}s but can be any-
160 widgets). The following example shows how we can set up a-
161 QGroupBox with a layout:-
