Detailed Description

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.

Member Function Documentation

◆ crs()

QgsCoordinateReferenceSystem QgsProjectionSelectionTreeWidget::crs ( ) const

Returns the CRS currently selected in the widget.

Since: QGIS 3.0

Definition at line 473 of file qgsprojectionselectiontreewidget.cpp.

◆ crsSelected

void QgsProjectionSelectionTreeWidget::crsSelected ( )

signal

Emitted when a projection is selected in the widget.

◆ hasValidSelection()

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"

◆ setOgcWmsCrsFilter

void QgsProjectionSelectionTreeWidget::setOgcWmsCrsFilter ( const QSet< QString > & crsFilter )

slot

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.
