示例1: currentSelected
void UBFeaturesWidget::currentSelected(const QModelIndex ¤t)
{
if (current.isValid())
{
QSortFilterProxyModel *model = dynamic_cast<QSortFilterProxyModel *>( featuresListView->model() );
/*QString name = model->data(current).toString();
QString path = model->data(current, Qt::UserRole).toString();
eUBLibElementType type = (eUBLibElementType)model->data(current, Qt::UserRole + 1).toInt();*/
UBFeature feature = model->data(current, Qt::UserRole + 1).value<UBFeature>();
if ( feature.isFolder() )
{
QString newPath = feature.getFullVirtualPath();
//pathViewer->addPathElement( feature.getThumbnail(), newPath );
controller->setCurrentElement( feature );
model->setFilterFixedString( newPath );
model->invalidate();

}示例2: callDataChanged
void DeferredUpdateTreeView::callDataChanged() {
// As the view update is asynchronous, if the original model is wrapped by a QSortFilterProxyModel
// it needs to be invalidate in order to rebuild the index mapping and prevent sefgault
QSortFilterProxyModel *qsfpm = dynamic_cast<QSortFilterProxyModel*>(model());
if (qsfpm) {
qsfpm->invalidate();
}
TreeViewUpdateTimer *tvut = static_cast<TreeViewUpdateTimer*>(sender());

QPair<QModelIndex, QModelIndex> p = qMakePair(tvut->topLeft, tvut->bottomRight);
delete _updateTimers[p];
_updateTimers.remove(p);
}示例3: deleteElements
void UBFeaturesWidget::deleteElements( const QMimeData & mimeData )
{
if ( !mimeData.hasUrls() )
return;
QList<QUrl> urls = mimeData.urls();
foreach ( QUrl url, urls )
{

}
else
{
