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