GroupBox does not provide a layout of its own, but + requires you to position its contents, for instance by creating a \l RowLayout + or a \l ColumnLayout. + + Items declared as children of a GroupBox are automatically parented to the + GroupBox's \l {Control::}{contentItem}. Items created dynamically need to be + explicitly parented to the contentItem. + + If only a single item is used within a GroupBox, it will resize to fit the + implicit size of its contained item. This makes it particularly suitable + for use together with layouts. + + \image qtquickcontrols2-groupbox.png + + \snippet qtquickcontrols2-groupbox.qml 1 + + \section2 Checkable GroupBox + + Even though GroupBox has no built-in check box, it is straightforward + to create a checkable GroupBox by pairing it with a CheckBox. + + \image qtquickcontrols2-groupbox-checkable.png + + It is a common pattern to enable or disable the groupbox's children when + its checkbox is toggled on or off, but it is up to the application to decide + on the behavior of the checkbox. + + \snippet qtquickcontrols2-groupbox-checkable.qml 1 + + \sa CheckBox, {Customizing GroupBox}, {Container Controls} +*/ + +class QQuickGroupBoxPrivate : public QQuickFramePrivate +{ +public: + QQuickGroupBoxPrivate() : label(nullptr) { } + + QString title; + QQuickItem *label; +}; + +QQuickGroupBox::QQuickGroupBox(QQuickItem *parent) : + QQuickFrame(*(new QQuickGroupBoxPrivate), parent) +{ +} + +/*! + \qmlproperty string QtQuick.Controls::GroupBox::title + + This property holds the title. + + The title is typically displayed above the groupbox to + summarize its contents. +*/ +QString QQuickGroupBox::title() const +{ + Q_D(const QQuickGroupBox); + return d->title; +} + +void QQuickGroupBox::setTitle(const QString &title) +{ + Q_D(QQuickGroupBox); + if (d->title == title) + return; + + d->title = title; + setAccessibleName(title); + emit titleChanged(); +} + +/*! + \qmlproperty Item QtQuick.Controls::GroupBox::label + + This property holds the label item that visualizes \l title. + + \sa {Customizing GroupBox} +*/ +QQuickItem *QQuickGroupBox::label() const +{ + Q_D(const QQuickGroupBox); + return d->label; +} + +void QQuickGroupBox::setLabel(QQuickItem *label) +{ + Q_D(QQuickGroupBox); + if (d->label == label) + return; + + d->deleteDelegate(d->label); + d->label = label; + if (label && !label->parentItem()) + label->setParentItem(this); + emit labelChanged(); +} + +QFont QQuickGroupBox::defaultFont() const +{ + return QQuickControlPrivate::themeFont(QPlatformTheme::GroupBoxTitleFont); +} + +#ifndef QT_NO_ACCESSIBILITY +QAccessible::Role QQuickGroupBox::accessibleRole() const +{ + return QAccessible::Grouping; +} + +void QQuickGroupBox::accessibilityActiveChanged(bool active) +{ + Q_D(QQuickGroupBox); + QQuickFrame::accessibilityActiveChanged(active); + + if (active) + setAccessibleName(d->title); +} +#endif // QT_NO_ACCESSIBILITY + +QT_END_NAMESPACE |
