Function documentation

QgsScaleVisibilityDialog::QgsScaleVisibilityDialog(QWidget* parent = nullptr, const QString& title = QString(), QgsMapCanvas* mapCanvas = nullptr) explicit

Constructor for QgsScaleVisibilityDialog, with specified dialog title.

The mapCanvas argument can be used to associate the dialog with a map canvas, allowing use of the current map scale within the dialog.

double QgsScaleVisibilityDialog::maximumScale() const

Returns the selected maximum 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.

double QgsScaleVisibilityDialog::minimumScale() const

Returns the selected minimum 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.

void QgsScaleVisibilityDialog::setMaximumScale(double scale) public slot

Set the maximum 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.

void QgsScaleVisibilityDialog::setMinimumScale(double scale) public slot

Set the minimum 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.

void QgsScaleVisibilityDialog::setScaleVisiblity(bool hasScaleVisibility) public slot

Set whether scale based visibility is enabled.
