Member Function Documentation

bool QgsOfflineEditing::convertToOfflineProject	(	const QString &	offlineDataPath,
		const QString &	offlineDbFile,
		const QStringList &	layerIds,
		bool	onlySelected = false,
		ContainerType	containerType = SpatiaLite
	)

Convert current project for offline editing.

convert current project to offline project returns offline project file path

Parameters

offlineDataPath	Path to offline db file
offlineDbFile	Offline db file name
layerIds	List of layer names to convert
onlySelected	Only copy selected features from layers where a selection is present
containerType	defines the SQLite file container type like SpatiaLite or GPKG

Workflow:

• copy layers to SpatiaLite
• create SpatiaLite db at offlineDataPath
• create table for each layer
• add new SpatiaLite layer
• copy features
• save as offline project
• mark offline layers
• remove remote layers
• mark as offline project

bool QgsOfflineEditing::isOfflineProject

(

)

const

Returns true if current project is offline.

void QgsOfflineEditing::layerProgressUpdated ( int  layer, int  numLayers  )

signal

Is 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.

void QgsOfflineEditing::progressModeSet ( QgsOfflineEditing::ProgressMode  mode, int  maximum  )

signal

Is emitted when the mode for the progress of the current operation is set.

Parameters

mode	progress mode
maximum	total number of entities to process in the current operation

void QgsOfflineEditing::progressStarted ( )

signal

The signal is emitted when the process has started.

void QgsOfflineEditing::progressStopped ( )

signal

Emitted when the processing of all layers has finished.

void QgsOfflineEditing::progressUpdated ( int  progress )

signal

Emitted with the progress of the current mode.

Parameters

progress

current index of processed entities

void QgsOfflineEditing::synchronize

(

)

Synchronize to remote layers.

Definition at line 211 of file qgsofflineediting.cpp.

void QgsOfflineEditing::warning ( const QString &  title, const QString &  message  )

signal

Emitted when a warning needs to be displayed.

Parameters

title	title string for message
message	A descriptive message for the warning
