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: -
