Detailed Description

A generic widget allowing users to pick a Coordinate Reference System (or define their own).

Since: QGIS 3.24

Constructor & Destructor Documentation

◆ QgsCrsSelectionWidget()

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.

Definition at line 32 of file qgsprojectionselectiondialog.cpp.

◆ ~QgsCrsSelectionWidget()

QgsCrsSelectionWidget::~QgsCrsSelectionWidget ( )

◆ crsChanged

void QgsCrsSelectionWidget::crsChanged ( )

signal

Emitted when the CRS defined in the widget is changed.

◆ crsDoubleClicked

void QgsCrsSelectionWidget::crsDoubleClicked ( const QgsCoordinateReferenceSystem & crs )

signal

Emitted when a CRS entry in the widget is double-clicked.

◆ filters()

QgsCoordinateReferenceSystemProxyModel::Filters QgsCrsSelectionWidget::filters ( ) const

Returns the filters set on the available CRS.

See also: setFilters()

Since: QGIS 3.36

Definition at line 193 of file qgsprojectionselectiondialog.cpp.

◆ hasValidSelection()

bool QgsCrsSelectionWidget::hasValidSelection ( ) const

Returns true if the widget has a valid CRS defined.

Definition at line 174 of file qgsprojectionselectiondialog.cpp.

◆ hasValidSelectionChanged

void QgsCrsSelectionWidget::hasValidSelectionChanged ( bool isValid )

signal

Emitted when the widget has a valid selection or not.

◆ setCrs

void QgsCrsSelectionWidget::setCrs ( const QgsCoordinateReferenceSystem & crs )

slot

Sets the crs to show within the widget.

See also: crs()

Definition at line 220 of file qgsprojectionselectiondialog.cpp.

◆ setFilters()

void QgsCrsSelectionWidget::setFilters ( QgsCoordinateReferenceSystemProxyModel::Filters filters )

Sets filters for the available CRS.

See also: filters()

Since: QGIS 3.36

Definition at line 198 of file qgsprojectionselectiondialog.cpp.

◆ setMessage()

void QgsCrsSelectionWidget::setMessage ( const QString & message )

Sets a message to show in the dialog.

Definition at line 119 of file qgsprojectionselectiondialog.cpp.

◆ setNotSetText()

void QgsCrsSelectionWidget::setNotSetText	(	const QString &	text,
		const QString &	description = `QString()`
	)

Sets the text to show for the not set option.

Note that this option is not shown by default and must be set visible by calling setShowNoCrs().

The description argument can be used to specify a detailed description which is shown when the option is selected.

Definition at line 162 of file qgsprojectionselectiondialog.cpp.

◆ setOgcWmsCrsFilter

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

slot

filters this dialog by the given CRSs

Sets this dialog to filter the available CRSs to those listed by the given Coordinate Reference Systems.

Parameters

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.

Warning: This function's behavior is undefined if it is called after the dialog is shown.

Definition at line 251 of file qgsprojectionselectiondialog.cpp.

◆ setShowNoCrs()

void QgsCrsSelectionWidget::setShowNoCrs ( bool show )

Sets whether a "no/invalid" CRS option should be shown.

If this option is selected, calling crs() will return an invalid QgsCoordinateReferenceSystem.

See also: showNoCrs()

Definition at line 126 of file qgsprojectionselectiondialog.cpp.

◆ showNoCrs()

bool QgsCrsSelectionWidget::showNoCrs ( ) const

Returns whether the "no/invalid" CRS option is shown.

If this option is selected, calling crs() will return an invalid QgsCoordinateReferenceSystem.
