maximumScale
(self) → float¶ Returns the selected maximum scale (i.e. most “zoomed in” scale), or 0 if maximum scale is not set. The scale value indicates the scale denominator, e.g. 1000.0 for a 1:1000 map.

setMaximumScale
(self, scale: float)¶ Set the maximum
scale

Warning
Calling setMinimumScale() places a restriction on the acceptable maximum scale for the widget, and will alter any previously set maximum scale to pass this constraint. Always call setMinimumScale() before setMaximumScale() when restoring a scale range in the widget, or use the convenience method setScaleRange() instead.
- Parameters
scale (float) –
-
setMinimumScale
(self, scale: float)¶ Set the minimum
scale
(i.e. most “zoomed out” scale), or 0 to indicate the minimum is not set. The scale value indicates the scale denominator, e.g. 1000.0 for a 1:1000 map.See also

setScaleRange
(self, min: float, max: float)¶ Sets the scale range, from

scale (i.e. most “zoomed out” scale) tomax
scale (most “zoomed in” scale). The scale values indicates the scale denominator, e.g. 1000.0 for a 1:1000 map, or 0 to indicate not set.See also
