QgsCrsSelectionWidget::QgsCrsSelectionWidget | ( | QWidget * | parent = nullptr , |
QgsCoordinateReferenceSystemProxyModel::Filters | filters = QgsCoordinateReferenceSystemProxyModel::FilterHorizontal | QgsCoordinateReferenceSystemProxyModel::FilterCompound |
||
) |
Constructor for QgsCrsSelectionWidget, with the specified parent widget.
Since QGIS 3.36, the optional filter argument can be used to specify filters on the systems shown in the widget. The default is to show all horizontal and compound CRS in order to match the behavior of older QGIS releases. The filter can be altered to also include vertical CRS if desired.

filters this dialog by the given CRSs
Sets this dialog to filter the available CRSs to those listed by the given Coordinate Reference Systems.
crsFilter | a list of OGC Coordinate Reference Systems to filter the list of CRS by. This is useful in (e.g.) WMS situations where you just want to offer what the WMS server can support. |
