Detailed Description

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

Constructor & Destructor Documentation

◆ QgsCrsSelectionWidget()

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 33 of file qgsprojectionselectiondialog.cpp.

◆ ~QgsCrsSelectionWidget()

QgsCrsSelectionWidget::~QgsCrsSelectionWidget ( )
override

Definition at line 108 of file qgsprojectionselectiondialog.cpp.

Member Function Documentation

◆ crs()

QgsCoordinateReferenceSystem QgsCrsSelectionWidget::crs ( ) const

signal

Emitted when the CRS defined in the widget is changed.

◆ crsDoubleClicked

void QgsCrsSelectionWidget::crsDoubleClicked ( const QgsCoordinateReferenceSystem crs)
signal

Definition at line 168 of file qgsprojectionselectiondialog.cpp.

◆ hasValidSelectionChanged

void QgsCrsSelectionWidget::hasValidSelectionChanged ( bool  isValid)
signal

Emitted when the widget has a valid selection or not.

◆ setCrs

slot

Sets the crs to show within the widget.

See also
crs()

Definition at line 214 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 192 of file qgsprojectionselectiondialog.cpp.

◆ setMessage()

void QgsCrsSelectionWidget::setMessage ( const QString &  message)

Sets a message to show in the dialog.

Definition at line 114 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 156 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
crsFiltera 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 245 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 120 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.
