setMapCanvas()

New in version 2.16.

Return type

QgsMapCanvas

metric()
minMaxOrigin(self) → QgsRasterMinMaxOrigin

Returns a QgsRasterMinMaxOrigin object with the widget values.

Return type

QgsRasterMinMaxOrigin

sampleSize(self) → int

Returns the selected sample size.

Return type

int

sender()
senderSignalIndex()
setBands(self, bands: Iterable[int])
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
