Class: QgsProjectionSelectionTreeWidget¶

class qgis.gui.QgsProjectionSelectionTreeWidget(parent: QWidget = None)¶

Bases: PyQt5.QtWidgets.QWidget

Constructor for QgsProjectionSelectionTreeWidget.

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.

setOgcWmsCrsFilter(self, crsFilter: Iterable[str])¶

filters this widget by the given CRSs

Sets this widget to filter the available projections to those listed by the given Coordinate Reference Systems.

Parameters: 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.

Warning

This function’s behavior is undefined if it is called after the widget is shown.
