void QgsProjectionSelector::initialized ( )

signal

Notify others that the widget is now fully initialized, including deferred selection of projection.

Note: added in 2.4

void QgsProjectionSelector::loadCrsList ( QSet< QString > * crsFilter = 0 )

Populate the proj tree view with system projection names...

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.

Todo:: Should this be public?

void QgsProjectionSelector::loadUserCrsList ( QSet< QString > * crsFilter = 0 )

Populate the proj tree view with user defined projection names...

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.

void QgsProjectionSelector::refresh ( )

signal

protected

Used to manage column sizes.

void QgsProjectionSelector::searchBoxHasFocus ( bool )

signal

Let listeners know if find has focus so they can adjust the default button.

QString QgsProjectionSelector::selectedAuthId ( )

Gets the current authority-style projection identifier.

long QgsProjectionSelector::selectedCrsId ( )

slot

Gets the current QGIS projection identfier.

QString QgsProjectionSelector::selectedName ( )

slot

long QgsProjectionSelector::selectedPostgresSrId ( )

slot

Gets the current PostGIS-style projection identifier.

QString QgsProjectionSelector::selectedProj4String ( )

slot

void QgsProjectionSelector::setOgcWmsCrsFilter ( 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.

Warning: This function's behaviour is undefined if it is called after the widget is shown.

void QgsProjectionSelector::setSelectedAuthId ( QString authId )

slot

void QgsProjectionSelector::setSelectedCrsId ( long theCRSID )

slot

void QgsProjectionSelector::setSelectedCrsName ( QString theCRSName )

slot

void QgsProjectionSelector::showEvent ( QShowEvent * theEvent )

protected

Used to ensure the projection list view is actually populated.

const QString QgsProjectionSelector::sqlSafeString ( const QString theSQL )

Make the string safe for use in SQL statements. This involves escaping single quotes, double quotes, backslashes, and optionally, percentage symbols. Percentage symbols are used as wildcards sometimes and so when using the string as part of the LIKE phrase of a select statement, should be escaped.

const QString in The input string to make safe.
Returns
The string made safe for SQL statements.
