void setMatch(const QgsPointLocator::Match &match)
Sets snapping match that should be displayed in map canvas. Invalid match hides the indicator...
QgsVectorLayer * layer() const
The vector layer where the snap occurred.
This class is a composition of two QSettings instances:
QgsPointLocator::Match match() const
Returns currently displayed snapping match.
Map canvas is a class for displaying all GIS data types on a canvas.
A class for marking vertices of features using e.g.
QgsPointXY point() const
for vertex / edge match coords depending on what class returns it (geom.cache: layer coords...
QVariant value(const QString &key, const QVariant &defaultValue=QVariant(), const Section section=NoSection) const
Returns the value for setting key.
bool isVisible() const
Returns whether the snapping indicator is visible.
void setVisible(bool visible=true)
Sets whether the snapping indicator is visible.
QgsSnapIndicator(QgsMapCanvas *canvas)
Constructs an indicator for the given map canvas.
