Parameters:

index – PySide6.QtCore.QModelIndex
role – int

Return type:

bool

Returns true if there exists role data for the item at index. Returns false in any other case.

PySide6.QtRemoteObjects.QAbstractItemModelReplica.initialized()#

The initialized signal is emitted the first time we receive data from the Source .

isInitialized()

PySide6.QtRemoteObjects.QAbstractItemModelReplica.isInitialized()#

Return type:: bool

Returns true if this replica has been initialized with data from the Source object. Returns false otherwise.

PySide6.QtRemoteObjects.QAbstractItemModelReplica.rootCacheSize()#

Return type:: int

Returns the current size of the internal cache. By default this is set to the value of the QTRO_NODES_CACHE_SIZE environment variable, or a default of 1000 if it is invalid or doesn’t exist.

PySide6.QtRemoteObjects.QAbstractItemModelReplica.selectionModel()#

Return type:: PySide6.QtCore.QItemSelectionModel

Returns a pointer to the QItemSelectionModel for the current QAbstractItemModelReplica .

PySide6.QtRemoteObjects.QAbstractItemModelReplica.setRootCacheSize(rootCacheSize)#

Parameters:: rootCacheSize – int

Sets the size of the internal cache to rootCacheSize.
