QgsCoordinateReferenceSystem crs() const
Returns the selected CRS for the new layer.
QgsWkbTypes::Type selectedType() const
Returns the selected geometry type.
This class is a composition of two QSettings instances:
Container of fields for a vector layer.
static QIcon getThemeIcon(const QString &name)
Helper to get a theme icon.
void saveGeometry(QWidget *widget, const QString &keyName)
Save the wigget geometry into settings.
bool restoreGeometry(QWidget *widget, const QString &keyName)
Restore the wigget geometry from settings.
void setValue(const QString &key, const QVariant &value, const QgsSettings::Section section=QgsSettings::NoSection)
Sets the value of setting key to value.
Type
The WKB type describes the number of dimensions a geometry has.
static Type addM(Type type)
Adds the m dimension to a WKB type and returns the new type.
static Type addZ(Type type)
Adds the z dimension to a WKB type and returns the new type.
void setCrs(const QgsCoordinateReferenceSystem &crs)
Sets the crs value for the new layer in the dialog.
static QgsVectorLayer * runAndCreateLayer(QWidget *parent=nullptr, const QgsCoordinateReferenceSystem &defaultCrs=QgsCoordinateReferenceSystem())
Runs the dialog and creates a new memory layer.
QVariant value(const QString &key, const QVariant &defaultValue=QVariant(), const Section section=NoSection) const
Returns the value for setting key.
This class represents a coordinate reference system (CRS).
static void openHelp(const QString &key)
Opens help topic for the given help key using default system web browser.

Represents a vector layer which manages a vector based data sets.
QgsNewMemoryLayerDialog(QWidget *parent=nullptr, Qt::WindowFlags fl=QgsGuiUtils::ModalDialogFlags)
QString layerName() const
Returns the layer name.
