A widget for selecting a coordinate reference system from a tree.
This widget implements a tree view of projections, as seen in the QgsProjectionSelectionDialog dialog. In most cases it is more suitable to use the compact QgsProjectionSelectionWidget widget.

bool QgsProjectionSelectionTreeWidget::hasValidSelection | ( | ) | const |
Returns true if the current selection in the widget is a valid choice.
Valid selections include any projection and also the "no/invalid projection" option (if setShowNoProjection() was called). Invalid selections are the group headers (such as "Geographic Coordinate Systems"

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