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.
Definition at line 105 of file qgsscalerangewidget.cpp.
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.
Definition at line 95 of file qgsscalerangewidget.cpp.
|
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.
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 74 of file qgsscalerangewidget.cpp.
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.

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.
Definition at line 100 of file qgsscalerangewidget.cpp.
|
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.
Definition at line 90 of file qgsscalerangewidget.cpp.
|
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.
