convertToOfflineProject(self, offlineDataPath: str | None, offlineDbFile: str | None, layerIds: Iterable[str | None], onlySelected: bool = False, containerType: QgsOfflineEditing.ContainerType = QgsOfflineEditing.SpatiaLite, layerNameSuffix: str | None = '') → bool[source]¶

Convert current project for offline editing

Parameters:

offlineDataPath (Optional[str]) – Path to offline db file
offlineDbFile (Optional[str]) – Offline db file name
layerIds (Iterable[Optional[str]]) – List of layer names to convert
onlySelected (bool = False) – Only copy selected features from layers where a selection is present
containerType (QgsOfflineEditing.ContainerType = QgsOfflineEditing.SpatiaLite) – defines the SQLite file container type like SpatiaLite or GPKG
layerNameSuffix (Optional[str] = '') – Suffix string added to the offline layer name

Return type:

bool

isOfflineProject(self) → bool[source]¶

Returns True if current project is offline

Return type:: bool

signal layerProgressUpdated(layer: int, numLayers: int)[source]¶

Emitted whenever a new layer is being processed. It is possible to estimate the progress of the complete operation by comparing the index of the current layer to the total amount numLayers.

Parameters:

layer (int)
numLayers (int)

signal progressModeSet(mode: QgsOfflineEditing.ProgressMode, maximum: int)[source]¶

Emitted when the mode for the progress of the current operation is set.

Parameters:

mode (QgsOfflineEditing.ProgressMode) – progress mode
maximum (int) – total number of entities to process in the current operation

signal progressStarted[source]¶: Emitted when the process has started.

signal progressStopped[source]¶: Emitted when the processing of all layers has finished

signal progressUpdated(progress: int)[source]¶

Emitted with the progress of the current mode

Parameters:: progress (int) – current index of processed entities

synchronize(self, useTransaction: bool = False)[source]¶

Synchronize to remote layers

Parameters:: useTransaction (bool = False) – enforce the remote layer modifications with the same source to be in a transaction group

signal warning(title: str, message: str)[source]¶

Emitted when a warning needs to be displayed.

Parameters:

title (str) – title string for message
message (str) – A descriptive message for the warning
