Protected Attributes inherited from Digikam::DragDropModelImplementation | |
| AbstractItemDragDropHandler * | m_dragDropHandler = nullptr |
| void ShowFoto::ShowfotoItemModel::addShowfotoItemInfoSynchronously | ( | const ShowfotoItemInfo & | info | ) |
This method first adds the info, synchronously. Only afterwards, the preprocessor will have the opportunity to process it. This method also bypasses any incremental updates.
|
signal |
The model is in polished, clean situation right now.
| QModelIndex ShowFoto::ShowfotoItemModel::indexForUrl | ( | const QUrl & | fileUrl | ) | const |
In case of multiple occurrences of the same file, the simpler overrides returns any one found first, use the QList methods to retrieve all occurrences.
|
signal |
This signal is sent before the model data is changed and views are informed.
|
signal |
This signal is sent before the model data is changed and views are informed. Note: You need to explicitly enable sending of this signal. It is not sent in clearShowfotoItemInfos().
|
signal |
This signal is sent after the model data is changed and views are informed.
|

This signal is sent after the model data is changed and views are informed. Note: You need to explicitly enable sending of this signal. It is not sent in clearShowfotoItemInfos().
|
signal |
This is guaranteed only for the scope of emitting this signal.
|
protected |
The signal will be emitted inline if the model is ready right now.
| void ShowFoto::ShowfotoItemModel::setKeepsFileUrlCache | ( | bool | keepCache | ) |
Default is false.
| void ShowFoto::ShowfotoItemModel::setSendRemovalSignals | ( | bool | send | ) |
Enable sending of itemInfosAboutToBeRemoved and itemsInfosRemoved signals. Default: false
| ShowfotoItemInfo ShowFoto::ShowfotoItemModel::showfotoItemInfo | ( | const QModelIndex & | index | ) | const |
For ShowfotoItemInfo and ShowfotoItemInfoId If the index is not valid they will return a null ShowfotoItemInfo, and 0 respectively, ShowfotoItemInfoRef must not be called with an invalid index as it will crash.
| ShowfotoItemInfo ShowFoto::ShowfotoItemModel::showfotoItemInfo | ( | int | row | ) | const |
Note that ShowfotoItemInfoRef must not be called with an invalid index as it will crash.
|
inlineprotectedvirtual |
Reimplemented in ShowFoto::ShowfotoThumbnailModel.
|

You shall only call this method from a slot connected to readyForIncrementalRefresh(). To initiate an incremental refresh, call requestIncrementalRefresh().
