Constructor & Destructor Documentation

◆ QgsScaleRangeWidget()

QgsScaleRangeWidget::QgsScaleRangeWidget ( QWidget *  parent = 0)
explicit

Constructor for QgsScaleRangeWidget.

Member Function Documentation

◆ maximumScale()

double QgsScaleRangeWidget::maximumScale ( ) const

Returns the selected maximum scale (i.e.

most "zoomed in" scale), or 0 if maximum scale is not set. The scale value indicates the scale denominator, e.g. 1000.0 for a 1:1000 map.

minimumScale()
setMaximumScale()

◆ minimumScale()

double QgsScaleRangeWidget::minimumScale ( ) const

Returns the selected minimum scale (i.e.

most "zoomed out" scale), or 0 if minimum scale is not set. The scale value indicates the scale denominator, e.g. 1000.0 for a 1:1000 map.

See also
maximumScale()
setMinimumScale()

◆ rangeChanged

void QgsScaleRangeWidget::rangeChanged ( double  min,
double  max 
)
signal

Emitted when the scale range set in the widget is changed.

The scale values indicates the scale denominator, e.g. 1000.0 for a 1:1000 map, or 0 to indicate not set.

Since
QGIS 2.16

◆ reloadProjectScales()

void QgsScaleRangeWidget::reloadProjectScales ( )

Call to reload the preset scales from the current project and apply them to the 2 scales combo boxes.

Definition at line 70 of file qgsscalerangewidget.cpp.

◆ setMapCanvas()

void QgsScaleRangeWidget::setMapCanvas ( QgsMapCanvas canvas)

Sets the map canvas which will be used for the current scale buttons.

If not set, the buttons are hidden.

Definition at line 81 of file qgsscalerangewidget.cpp.

◆ setMaximumScale

void QgsScaleRangeWidget::setMaximumScale ( double  scale)
slot

Set the maximum scale (i.e.

most "zoomed in" scale), or 0 to indicate the minimum is not set. The scale value indicates the scale denominator, e.g. 1000.0 for a 1:1000 map.

See also
maximumScale()
setMinimumScale()
setScaleRange()

Definition at line 97 of file qgsscalerangewidget.cpp.

◆ setMinimumScale

void QgsScaleRangeWidget::setMinimumScale ( double  scale)
slot

Set the minimum scale (i.e.

most "zoomed out" scale), or 0 to indicate the minimum is not set. The scale value indicates the scale denominator, e.g. 1000.0 for a 1:1000 map.

See also
minimumScale()
setMaximumScale()
setScaleRange()

Definition at line 87 of file qgsscalerangewidget.cpp.

◆ setScaleRange

void QgsScaleRangeWidget::setScaleRange ( double  min,
double  max 
)
slot

Sets the scale range, from min scale (i.e.

most "zoomed out" scale) to max scale (most "zoomed in" scale). The scale values indicates the scale denominator, e.g. 1000.0 for a 1:1000 map, or 0 to indicate not set.
