extent(self) → QgsRectangle

Returns the extent selected by the user. Either an empty extent for ‘full’ or the current visible extent.

focusNextPrevChild()
focusOutEvent()
focusPreviousChild()
hideEvent()
hideUpdatedExtent(self)

Hide updated extent choice

isCollapsed(self) → bool

Returns if the widget is collaped.

isSignalConnected()
keyPressEvent()
keyReleaseEvent()
leaveEvent()
load

signal emitted when new min/max values are computed from statistics. [signal]

mapCanvas(self) → QgsMapCanvas

Returns the map canvas associated with the widget.

setMapCanvas()

New in version 2.16.

metric()
minMaxOrigin(self) → QgsRasterMinMaxOrigin

Returns a QgsRasterMinMaxOrigin object with the widget values.

moveEvent()
nativeEvent()
paintEvent()
receivers()
resizeEvent()
sampleSize(self) → int

Returns the selected sample size.

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

Sets collapsed state of widget

setExtent(self, extent: QgsRectangle)

Sets the extent to use for minimum and maximum value calculation.

Parameters:extent – 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 – map canvas

wheelEvent()
widgetChanged

Emitted when something on the widget has changed. All widgets will fire this event to notify of an internal change. [signal]
