◆ 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 159 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 238 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 123 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.
