Two errors in QtitanRibbonInstaller5.0.0_beta2_msvc2017.exe

2 weeks 5 days ago #1 by yimin
The first error is :
void BackstageSharedWindow::updateRequest(bool qwidgetupdate)
{
for (QSet<BackstageWidget*>::const_iterator it = m_widgets.constBegin();
it != m_widgets.constEnd(); ++it)
{
BackstageWidget* backstageWidget = *it;
QWidget* w = backstageWidget->widget();
if (w == Q_NULL)
continue;
QRegion region = backstageWidget->m_needsRepaint;

if (qwidgetupdate)
{
qtn_add_dirty_region(w, region, w->geometry().topLeft());
backstageWidget->m_needsRepaint = region;
}
else
{
QGraphicsItemPrivate* item =
QGraphicsItemPrivate::get(backstageWidget->m_proxyWidget);
if (item->dirty)
region += item->needsRepaint.toRect();
region -= backstageWidget->m_needsRepaint; //Already was painted
backstageWidget->m_needsRepaint = QRegion();

}

if (region.isEmpty())
continue;
QList<QRectF> rects;
for (QRegion::const_iterator it = rects.begin(); it != rects.end(); ++it)
rects.append(*it);
backstageWidget->changed(rects);

}
}

The second error is :
#if (QT_VERSION >= QT_VERSION_CHECK(5, 0, 0))
#define QTN_FALLTHROUGH() Q_FALLTHROUGH()
#else // (QT_VERSION >= QT_VERSION_CHECK(5, 0, 0))
#define QTN_FALLTHROUGH()
#endif

Q_FALLTHROUGH() is not found.

I got it, The QtitanRibbon 5.0 must be used with qt 5.12, and I use qt 5.7.

To fix the compilation issue please change the macro to:
#if (QT_VERSION >= QT_VERSION_CHECK(5, 8, 0))
#define QTN_FALLTHROUGH() Q_FALLTHROUGH()
#else // (QT_VERSION >= QT_VERSION_CHECK(5, 8, 0))
#define QTN_FALLTHROUGH()
#endif

Fix will be added to the next update.

QList<QRectF> rects;
for (QRegion::const_iterator it = rects.begin(); it != rects.end(); ++it)
rects.append(*it);
backstageWidget->changed(rects);

Could you add some comments regarding this issue? What is the essence of the error?
