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 setMapCanvas(QgsMapCanvas *canvas)
Sets the map canvas which will be used for the current scale buttons.
void setMinimumScale(double scale)
Set the minimum scale (i.e.
void setMaximumScale(double scale)
Set the maximum scale (i.e.
void setMaximumScale(double scale)
Set the maximum scale, or 0 to indicate the minimum is not set.
void setMinimumScale(double scale)
Set the minimum scale, or 0 to indicate the minimum is not set.
QgsScaleVisibilityDialog(QWidget *parent=nullptr, const QString &title=QString(), QgsMapCanvas *mapCanvas=nullptr)
Constructor for QgsScaleVisibilityDialog, with specified dialog title.
void setScaleVisiblity(bool hasScaleVisibility)
Set whether scale based visibility is enabled.
