Map canvas is a class for displaying all GIS data types on a canvas.
Definition: qgsmapcanvas.h:90
A widget allowing entry of a range of map scales, e.g.
void rangeChanged(double min, double max)
Emitted when the scale range set in the widget is changed.
A combobox which lets the user select map scale from predefined list and highlights nearest to curren...
