GeometryType
The geometry types are used to group Qgis::WkbType in a coarse way.
Definition qgis.h:274
@ Polygon
Polygons.
This class represents a coordinate reference system (CRS).
A geometry is the spatial representation of a feature.
An abstract class for items that can be placed on the map canvas.
Map canvas is a class for displaying all GIS data types on a canvas.
Base class for all map layer types.
Definition qgsmaplayer.h:75
A class to represent a 2D point.
Definition qgspointxy.h:60
A class for drawing transient features (e.g.
~QgsRubberBand() override
QColor fillColor() const
Returns the current fill color.
IconType icon() const
Returns the current icon type to highlight point geometries.
@ ICON_X
A cross is used to highlight points (x)
@ ICON_FULL_DIAMOND
A diamond is used to highlight points (◆)
@ ICON_FULL_BOX
A full box is used to highlight points (■)
@ ICON_NONE
No icon is used.
@ ICON_CROSS
A cross is used to highlight points (+)
@ ICON_CIRCLE
A circle is used to highlight points (○)
@ ICON_DIAMOND
A diamond is used to highlight points (◇)
@ ICON_BOX
A box is used to highlight points (□)
QColor secondaryStrokeColor() const
Returns the current secondary stroke color.
int iconSize() const
Returns the current icon size of the point icons.
int width() const
Returns the current width of the line or stroke width for polygon.
QColor strokeColor() const
Returns the current stroke color.
Abstract base class for all rendered symbols.
Definition qgssymbol.h:94
