SublayerPromptMode
Specifies how to handle layer sources with multiple sublayers.
@ AlwaysAsk
Always ask users to select from available sublayers, if sublayers are present.
@ NeverAskLoadAll
Never ask users to select sublayers, instead automatically load all available sublayers.
@ NeverAskSkip
Never ask users to select sublayers, instead don't load anything.
static void enableAutoGeometryRestore(QWidget *widget, const QString &key=QString())
Register the widget to allow its position to be automatically saved and restored when open and closed...
QVariantMap decodeUri(const QString &providerKey, const QString &uri)
Breaks a provider data source URI into its component paths (e.g.
static QgsProviderRegistry * instance(const QString &pluginPath=QString())
Means of accessing canonical single instance.
This class is a composition of two QSettings instances:
QVariant value(const QString &key, const QVariant &defaultValue=QVariant(), Section section=NoSection) const
Returns the value for setting key.
void setValue(const QString &key, const QVariant &value, QgsSettings::Section section=QgsSettings::NoSection)
Sets the value of setting key to value.
T enumValue(const QString &key, const T &defaultValue, const Section section=NoSection)
Returns the setting value for a setting based on an enum.
bool mShowType
Whether to show type in the table.
QList< QgsSublayersDialog::LayerDefinition > LayerDefinitionList
List of layer definitions for the purpose of this dialog.
Q_DECL_DEPRECATED QgsSublayersDialog(ProviderType providerType, const QString &name, QWidget *parent=nullptr, Qt::WindowFlags fl=Qt::WindowFlags(), const QString &dataSourceUri=QString())
Constructor for QgsSublayersDialog.
LayerDefinitionList selection()
Returns list of selected layers.
bool mShowCount
Whether to show number of features in the table.
bool mShowDescription
Whether to show description in the table.
~QgsSublayersDialog() override
void populateLayerTable(const LayerDefinitionList &list)
Populate the table with layers.
int countColumn() const
Returns column with count or -1.
QString mName
Provider type name.
@ Uncounted
Feature count not yet computed.
@ UnknownCount
Provider returned an unknown feature count.
bool operator<(const QVariant &v1, const QVariant &v2)
Compares two QVariant values and returns whether the first is less than the second.
A structure that defines layers for the purpose of this dialog.
QString layerName
Name of the layer (not necessarily unique)
QString type
Extra type depending on the use (e.g. geometry type for vector sublayers)
int layerId
Identifier of the layer (one unique layer id may have multiple types though)
