void setMaximumScale(double scale)
Set the maximum scale, or 0 to indicate the minimum is not set.
void setMaximumScale(double scale)
Set the maximum scale (i.e.
bool hasScaleVisibility() const
Return true if scale based visibilty is enabled.
Map canvas is a class for displaying all GIS data types on a canvas.
Definition: qgsmapcanvas.h:74
void setScaleVisiblity(bool hasScaleVisibility)
Set whether scale based visibility is enabled.
void setMinimumScale(double scale)
Set the minimum scale (i.e.
double maximumScale() const
Returns the selected maximum scale, or 0 if maximum scale is not set.
QgsScaleVisibilityDialog(QWidget *parent=0, const QString &title=QString(), QgsMapCanvas *mapCanvas=nullptr)
Constructor for QgsScaleVisibilityDialog, with specified dialog title.
A widget allowing entry of a range of map scales, e.g.
void setMinimumScale(double scale)
Set the minimum scale, or 0 to indicate the minimum is not set.
double minimumScale() const
Returns the selected minimum scale, or 0 if minimum scale is not set.
void setMapCanvas(QgsMapCanvas *canvas)
Sets the map canvas which will be used for the current scale buttons.
