Constructor & Destructor Documentation

QgsRasterMinMaxWidget::QgsRasterMinMaxWidget	(	QgsRasterLayer *	layer,
		QWidget *	parent = nullptr
	)

Constructor for QgsRasterMinMaxWidget.

Definition at line 32 of file qgsrasterminmaxwidget.cpp.

Member Function Documentation

void QgsRasterMinMaxWidget::doComputations

(

)

Load programmatically with current values.

Definition at line 183 of file qgsrasterminmaxwidget.cpp.

QgsRectangle QgsRasterMinMaxWidget::extent

(

)

Returns the extent selected by the user.

Either an empty extent for 'full' or the current visible extent.

Definition at line 70 of file qgsrasterminmaxwidget.cpp.

void QgsRasterMinMaxWidget::hideUpdatedExtent

(

)

Hide updated extent choice.

Definition at line 244 of file qgsrasterminmaxwidget.cpp.

bool QgsRasterMinMaxWidget::isCollapsed ( ) const

inline

Returns if the widget is collaped.

Definition at line 97 of file qgsrasterminmaxwidget.h.

void QgsRasterMinMaxWidget::load ( int  bandNo, double  min, double  max  )

signal

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

QgsMapCanvas * QgsRasterMinMaxWidget::mapCanvas

(

)

Returns the map canvas associated with the widget.

See also

setMapCanvas()

Since

QGIS 2.16

Definition at line 59 of file qgsrasterminmaxwidget.cpp.

QgsRasterMinMaxOrigin QgsRasterMinMaxWidget::minMaxOrigin

(

)

Returns a QgsRasterMinMaxOrigin object with the widget values.

Definition at line 142 of file qgsrasterminmaxwidget.cpp.

int QgsRasterMinMaxWidget::sampleSize ( )

inline

Returns the selected sample size.

Definition at line 79 of file qgsrasterminmaxwidget.h.

void QgsRasterMinMaxWidget::setBands

(

const QList< int > &

bands

)

Definition at line 64 of file qgsrasterminmaxwidget.cpp.

void QgsRasterMinMaxWidget::setCollapsed ( bool  b )

inline

Sets collapsed state of widget.

Definition at line 100 of file qgsrasterminmaxwidget.h.

void QgsRasterMinMaxWidget::setExtent ( const QgsRectangle &  extent )

inline

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.

Definition at line 51 of file qgsrasterminmaxwidget.h.

void QgsRasterMinMaxWidget::setFromMinMaxOrigin

(

const QgsRasterMinMaxOrigin &

minMaxOrigin

)

Sets the "source" of min/max values.

Definition at line 97 of file qgsrasterminmaxwidget.cpp.

void QgsRasterMinMaxWidget::setMapCanvas

(

QgsMapCanvas *

canvas

)

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

See also

mapCanvas()

Since

QGIS 2.16

Definition at line 54 of file qgsrasterminmaxwidget.cpp.

void QgsRasterMinMaxWidget::userHasSetManualMinMaxValues

(

)

Uncheck cumulative cut, min/max, std-dev radio buttons.

Definition at line 84 of file qgsrasterminmaxwidget.cpp.

void QgsRasterMinMaxWidget::widgetChanged ( )

signal

Emitted when something on the widget has changed.

All widgets will fire this event to notify of an internal change.
