Returns the extent selected by the user.
Hide updated extent choice
Returns if the widget is collaped.
Returns the map canvas associated with the widget.
Returns a
QgsRasterMinMaxOrigin
object with the widget values.Returns the selected sample size.
- param bands
Sets collapsed state of widget
Sets the extent to use for minimum and maximum value calculation.
Sets the “source” of min/max values.
Sets the map canvas associated with the widget.
Uncheck cumulative cut, min/max, std-dev radio buttons
Signals
signal emitted when new min/max values are computed from statistics.
Emitted when something on the widget has changed.

- Parameters
bands (Iterable[int]) –
- setCollapsed(self, b: bool)¶
Sets collapsed state of widget
- Parameters
b (bool) –
- setExtent(self, extent: QgsRectangle)¶
Sets the extent to use for minimum and maximum value calculation.
- Parameters
extent (QgsRectangle) – extent in raster layer’s CRS
Note
if a map canvas is set using
setMapCanvas()
, its extent will take precedence over any extent set using this method.
- setFromMinMaxOrigin(self, QgsRasterMinMaxOrigin)¶
Sets the “source” of min/max values.
- setMapCanvas(self, canvas: QgsMapCanvas)¶
Sets the map canvas associated with the widget. This allows the widget to retrieve the current map extent from the canvas. If a canvas is set it will take precedence over any extent set from calling
setExtent()
.- Parameters
canvas (QgsMapCanvas) – map canvas
