This class represents a coordinate reference system (CRS).
A generic widget allowing users to pick a Coordinate Reference System (or define their own).
void hasValidSelectionChanged(bool isValid)
Emitted when the widget has a valid selection or not.
void crsDoubleClicked(const QgsCoordinateReferenceSystem &crs)
Emitted when a CRS entry in the widget is double-clicked.
void crsChanged()
Emitted when the CRS defined in the widget is changed.
Base class for any widget that can be shown as a inline panel.
A generic dialog to prompt the user for a Coordinate Reference System.
