QgsRasterMinMaxWidget::QgsRasterMinMaxWidget | ( | QgsRasterLayer * | layer, |
QWidget * | parent = nullptr |
||
) |
Constructor for QgsRasterMinMaxWidget.
Definition at line 32 of file qgsrasterminmaxwidget.cpp.
void QgsRasterMinMaxWidget::doComputations | ( | ) |
Load programmatically with current values.
Definition at line 185 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 74 of file qgsrasterminmaxwidget.cpp.
void QgsRasterMinMaxWidget::hideUpdatedExtent | ( | ) |
Hide updated extent choice.
Definition at line 248 of file qgsrasterminmaxwidget.cpp.
|
inline |
Returns if the widget is collaped.
Definition at line 95 of file qgsrasterminmaxwidget.h.
|
signal |
signal emitted when new min/max values are computed from statistics.
QgsMapCanvas * QgsRasterMinMaxWidget::mapCanvas | ( | ) |
Returns the map canvas associated with the widget.
Definition at line 63 of file qgsrasterminmaxwidget.cpp.
QgsRasterMinMaxOrigin QgsRasterMinMaxWidget::minMaxOrigin | ( | ) |
Returns a QgsRasterMinMaxOrigin object with the widget values.
Definition at line 144 of file qgsrasterminmaxwidget.cpp.
|
inline |
Returns the selected sample size.
Definition at line 77 of file qgsrasterminmaxwidget.h.
void QgsRasterMinMaxWidget::setBands | ( | const QList< int > & | bands | ) |
Definition at line 68 of file qgsrasterminmaxwidget.cpp.
|
inline |
Sets collapsed state of widget.
Definition at line 98 of file qgsrasterminmaxwidget.h.
|
inline |
Sets the extent to use for minimum and maximum value calculation.
extent | extent in raster layer's CRS |
Definition at line 51 of file qgsrasterminmaxwidget.h.
void QgsRasterMinMaxWidget::setFromMinMaxOrigin | ( | const QgsRasterMinMaxOrigin & | minMaxOrigin | ) |
Sets the "source" of min/max values.
Definition at line 101 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().

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