Invariably, - different platforms have their dialog buttons in different orders. - DialogButtonBox allows a developer to add buttons to it and will - automatically use the appropriate order for the user's platform. - - Most buttons for a dialog follow certain roles. Such roles include: - - \list - \li Accepting or rejecting the dialog. - \li Asking for help. - \li Performing actions on the dialog itself (such as resetting fields or - applying changes). - \endlist - - There can also be alternate ways of dismissing the dialog which may cause - destructive results. - - Most dialogs have buttons that can almost be considered standard (e.g. - \uicontrol OK and \uicontrol Cancel buttons). It is sometimes convenient - to create these buttons in a standard way. - - There are a couple ways of using DialogButtonBox. One way is to specify - the standard buttons (e.g. \uicontrol OK, \uicontrol Cancel, \uicontrol Save) - and let the button box setup the buttons. - - \image qtquickcontrols2-dialogbuttonbox.png - - \snippet qtquickcontrols2-dialogbuttonbox.qml 1 - - Alternatively, buttons and their roles can be specified by hand: - - \snippet qtquickcontrols2-dialogbuttonbox-attached.qml 1 - - You can also mix and match normal buttons and standard buttons. - - When a button is clicked in the button box, the \l clicked() signal is - emitted for the actual button that is pressed. In addition, the - following signals are automatically emitted when a button with the - respective role(s) is pressed: - - \table - \header - \li Role - \li Signal - \row - \li \c AcceptRole, \c YesRole - \li \l accepted() - \row - \li \c ApplyRole - \li \l applied() - \row - \li \c DiscardRole - \li \l discarded() - \row - \li \c HelpRole - \li \l helpRequested() - \row - \li \c RejectRole, \c NoRole - \li \l rejected() - \row - \li \c ResetRole - \li \l reset() - \endtable - - \sa Dialog -*/ - -/*! - \qmlsignal QtQuick.Controls::DialogButtonBox::accepted() - - This signal is emitted when a button defined with the \c AcceptRole or - \c YesRole is clicked. - - \sa rejected(), clicked(), helpRequested() -*/ - -/*! - \qmlsignal QtQuick.Controls::DialogButtonBox::rejected() - - This signal is emitted when a button defined with the \c RejectRole or - \c NoRole is clicked. - - \sa accepted(), helpRequested(), clicked() -*/ - -/*! - \since QtQuick.Controls 2.3 (Qt 5.10) - \qmlsignal QtQuick.Controls::DialogButtonBox::applied() - - This signal is emitted when a button defined with the \c ApplyRole is - clicked. - - \sa discarded(), reset() -*/ - -/*! - \since QtQuick.Controls 2.3 (Qt 5.10) - \qmlsignal QtQuick.Controls::DialogButtonBox::reset() - - This signal is emitted when a button defined with the \c ResetRole is - clicked. - - \sa discarded(), applied() -*/ - -/*! - \since QtQuick.Controls 2.3 (Qt 5.10) - \qmlsignal QtQuick.Controls::DialogButtonBox::discarded() - - This signal is emitted when a button defined with the \c DiscardRole is - clicked. - - \sa reset(), applied() -*/ - -/*! - \qmlsignal QtQuick.Controls::DialogButtonBox::helpRequested() - - This signal is emitted when a button defined with the \c HelpRole is clicked. - - \sa accepted(), rejected(), clicked() -*/ - -/*! - \qmlsignal QtQuick.Controls::DialogButtonBox::clicked(AbstractButton button) - - This signal is emitted when a \a button inside the button box is clicked. - - \sa accepted(), rejected(), helpRequested() -*/ - -static QPlatformDialogHelper::ButtonLayout platformButtonLayout() -{ - return QGuiApplicationPrivate::platformTheme()->themeHint(QPlatformTheme::DialogButtonBoxLayout).value<QPlatformDialogHelper::ButtonLayout>(); -} - -void QQuickDialogButtonBoxPrivate::itemImplicitWidthChanged(QQuickItem *item) -{ - QQuickContainerPrivate::itemImplicitWidthChanged(item); - if (item == contentItem) - resizeContent(); - else - updateImplicitContentWidth(); -} - -void QQuickDialogButtonBoxPrivate::itemImplicitHeightChanged(QQuickItem *item) -{ - QQuickContainerPrivate::itemImplicitHeightChanged(item); - if (item == contentItem) - resizeContent(); - else - updateImplicitContentHeight(); -} - -// adapted from QStyle::alignedRect() -static QRectF alignedRect(Qt::LayoutDirection direction, Qt::Alignment alignment, const QSizeF &size, const QRectF &rectangle) -{ - alignment = QGuiApplicationPrivate::visualAlignment(direction, alignment); - qreal x = rectangle.x(); - qreal y = rectangle.y(); - qreal w = size.width(); - qreal h = size.height(); - if ((alignment & Qt::AlignVCenter) == Qt::AlignVCenter || (alignment & Qt::AlignVertical_Mask) == 0) - y += (rectangle.size().height() - h) / 2; - else if ((alignment & Qt::AlignBottom) == Qt::AlignBottom) - y += rectangle.size().height() - h; - if ((alignment & Qt::AlignRight) == Qt::AlignRight) - x += rectangle.size().width() - w; - else if ((alignment & Qt::AlignHCenter) == Qt::AlignHCenter) - x += (rectangle.size().width() - w) / 2; - return QRectF(x, y, w, h); -} - -void QQuickDialogButtonBoxPrivate::resizeContent() -{ - Q_Q(QQuickDialogButtonBox); - if (!contentItem) - return; - - QRectF geometry = q->boundingRect().adjusted(q->leftPadding(), q->topPadding(), -q->rightPadding(), -q->bottomPadding()); - if (alignment != 0) - geometry = alignedRect(q->isMirrored() ?
