232#endif // QGSEXTENTGROUPBOX_H
A groupbox that collapses/expands when toggled and can save its collapsed and checked states.
This class represents a coordinate reference system (CRS).
Collapsible group box for configuration of extent, typically for a save operation.
ExtentState
Available states for the current extent selection in the widget.
@ UserExtent
Extent manually entered/modified by the user.
@ CurrentExtent
Map canvas extent.
@ ProjectLayerExtent
Extent taken from a layer within the project.
@ DrawOnCanvas
Extent taken from a rectangled drawn onto the map canvas.
@ OriginalExtent
Layer's extent.
void extentChanged(const QgsRectangle &r)
Emitted when the widget's extent is changed.
A widget for configuration of a map extent.
Map canvas is a class for displaying all GIS data types on a canvas.
Base class for all map layer types.
