Подробное описаниеThe QGroupBox widget provides a group box frame with a title. 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. QGroupBox also lets you set the title (normally set in the constructor) and the title's alignment. Group boxes can be checkable; child widgets in checkable group boxes are enabled or disabled depending on whether or not the group box is checked. You can minimize the space consumption of a group box by enabling the flat property. In most styles, enabling this property results in the removal of the left, right and bottom edges of the frame. QGroupBox doesn't automatically lay out the child widgets (which are often QCheckBoxes or QRadioButtons but can be any widgets). The following example shows how we can set up a QGroupBox with a layout: QGroupBox *groupBox = new QGroupBox(tr("Exclusive Radio Buttons")); QRadioButton *radio1 = new QRadioButton(tr("&Radio button 1")); QRadioButton *radio2 = new QRadioButton(tr("R&adio button 2")); QRadioButton *radio3 = new QRadioButton(tr("Ra&dio button 3")); radio1->setChecked(true); QVBoxLayout *vbox = new QVBoxLayout; vbox->addWidget(radio1); vbox->addWidget(radio2); vbox->addWidget(radio3); vbox->addStretch(1); groupBox->setLayout(vbox);

The default alignment is Qt::AlignLeft. Функции доступа:
Смотрите также Qt::Alignment. checkable : boolThis property holds whether the group box has a checkbox in its title. If this property is true, the group box displays its title using a checkbox in place of an ordinary label. If the checkbox is checked, the group box's children are enabled; otherwise they are disabled and inaccessible. By default, group boxes are not checkable. If this property is enabled for a group box, it will also be initially checked to ensure that its contents are enabled. Функции доступа:
Смотрите также checked. checked : boolThis property holds whether the group box is checked. If the group box is checkable, it is displayed with a check box. If the check box is checked, the group box's children are enabled; otherwise the children are disabled and are inaccessible to the user. By default, checkable group boxes are also checked.

If this property is enabled, only the top part of the frame is drawn in most styles; otherwise the whole frame is drawn. By default, this property is disabled; i.e. group boxes are not flat unless explicitly specified. Note: In some styles, flat and non-flat group boxes have similar representations and may not be as distinguishable as they are in other styles. Функции доступа:
See also title. title : QStringThis property holds the group box title text. The group box title text will have a keyboard shortcut if the title contains an ampersand ('&') followed by a letter. g->setTitle("&User information"); In the example above, Alt+U moves the keyboard focus to the group box. See the QShortcut documentation for details (to display an actual ampersand, use '&&'). There is no default title text. Функции доступа:

QGroupBox::QGroupBox ( const QString & title, QWidget * parent = 0 )Constructs a group box with the given title and parent. QGroupBox::~QGroupBox ()Destroys the group box. void QGroupBox::changeEvent ( QEvent * ev ) [virtual protected]Переопределено от QWidget::changeEvent(). void QGroupBox::childEvent ( QChildEvent * c ) [virtual protected]Переопределено из QObject::childEvent(). void QGroupBox::clicked ( bool checked = false ) [signal]This signal is emitted when the check box is activated (i.e. pressed down then released while the mouse cursor is inside the button), or when the shortcut key is typed, Notably, this signal is not emitted if you call setChecked(). If the check box is checked checked is true; it is false if the check box is unchecked. Эта функция была введена в Qt 4.2. See also checkable, toggled(), and checked. bool QGroupBox::event ( QEvent * e ) [virtual protected]Переопределено от QObject::event(). void QGroupBox::focusInEvent ( QFocusEvent * fe ) [virtual protected]Переопределено из QWidget::focusInEvent(). void QGroupBox::initStyleOption ( QStyleOptionGroupBox * option ) const [protected]Initialize option with the values from this QGroupBox. This method is useful for subclasses when they need a QStyleOptionGroupBox, but don't want to fill in all the information themselves. Смотрите также QStyleOption::initFrom().
