static QRegularExpression shortNameRegularExpression()
Returns the short name regular expression for line edit validator.
Layer tree group node serves as a container for layers and further groups.
QString name() const override
Returns the group's name.
Layer tree node points to a map layer.
QgsMapLayer * layer() const
Returns the map layer associated with this node.
This class is a base class for nodes in a layer tree.
@ NodeGroup
Container of other groups and layers.
QList< QgsLayerTreeNode * > children()
Gets list of children of the node. Children are owned by the parent.
QVariant customProperty(const QString &key, const QVariant &defaultValue=QVariant()) const
Read a custom property from layer. Properties are stored in a map and saved in project file.
NodeType nodeType() const
Find out about type of the node. It is usually shorter to use convenience functions from QgsLayerTree...
QString shortName() const
Returns the short name of the layer used by QGIS Server to identify the layer.
Base class for all map layer types.
QgsMapLayerServerProperties * serverProperties()
Returns QGIS Server Properties for the map layer.
static QString displayValidationError(QgsProjectServerValidator::ValidationError error)
Returns a human readable string for a given error.
ValidationError
Errors that might be raised by the validation process.
@ LayerEncoding
Encoding is not correctly set on a vector layer.
@ ProjectRootNameConflict
The project root name is already used by a layer or a group.
@ ProjectShortName
The project short name is not valid.
@ DuplicatedNames
A duplicated layer/group name in the layer tree.
@ LayerShortName
Layer/group short name is not valid.
static bool validate(QgsProject *project, QList< QgsProjectServerValidator::ValidationResult > &results)
Validates a project to detect problems on QGIS Server, and returns true if it's considered valid.
Encapsulates a QGIS project, including sets of map layers and their styles, layouts,...
QString title() const
Returns the project's title.
QString readEntry(const QString &scope, const QString &key, const QString &def=QString(), bool *ok=nullptr) const
Reads a string from the specified scope and key.
QgsLayerTree * layerTreeRoot() const
Returns pointer to the root (invisible) node of the project's layer tree.
QString encoding() const
Returns the encoding which is used for accessing data.
Represents a vector layer which manages a vector based data sets.
QgsVectorDataProvider * dataProvider() FINAL
Returns the layer's data provider, it may be nullptr.
Contains the parameters describing a project validation failure.
