Member Function Documentation

virtual void makVrf::DtMapScaleInstance::getSize	(	int &	width,
		int &	height
	)

virtual

Returns the maximal width/height of this object.

Implements makVrf::DtMapInformationOverlayInstance.

virtual void makVrf::DtMapScaleInstance::channelUpdated ( )

protectedvirtual

Called when the channel is updated.

Implements makVrf::DtMapInformationOverlayInstance.

virtual void makVrf::DtMapScaleInstance::destroyVisuals ( )

protectedvirtual

Overrides needed to be implemented by subclasses.

Destroy any visuals created for the overlay

Implements makVrf::DtMapInformationOverlayInstance.

virtual void makVrf::DtMapScaleInstance::createVisuals ( )

protectedvirtual

Create any visuals needed for the overlay.

Implements makVrf::DtMapInformationOverlayInstance.

virtual void makVrf::DtMapScaleInstance::reloadTextFonts ( )

protectedvirtual

Subclasses should re implement this function to reset the font on any allocated text items to support runtime font size changes.

Reimplemented from makVrf::DtMapInformationOverlayInstance.

virtual double makVrf::DtMapScaleInstance::findDistanceFromResolution	(	double	viewResolution,
		makVrv::DtUnicode &	label
	)		const

protectedvirtual

Given a view resoltion (meters/pixel) get a distance that will be used to display on the screen.

virtual void makVrf::DtMapScaleInstance::slot_onUnitChanged	(	int	attribute,
		int	from,
		int	old
	)

protectedvirtual

Connected to signal_displayUnitChanged on DtDisplayUnitsSettingsSignaler.

Calls refreshLabels if the attribute is Distance

virtual double makVrf::DtMapScaleInstance::roundToMeter	(	double	metersDistance,
		makVrv::DtUnicode &	label,
		bool	changeToKm = `true`
	)		const

protectedvirtual

Rounds the current distance to a displayabe meter (or kilometer) representation.

virtual double makVrf::DtMapScaleInstance::roundToFeet	(	double	metersDistance,
		makVrv::DtUnicode &	label
	)		const

protectedvirtual

Rounds using feet as measurement, however, will still return meters as a result.

It is the label that is at issue in this calculation

		makVrv::DtUnicode &	label
	)		const

protectedvirtual

Rounds using nauticalMiles as measurement, however, will still return meters as a result.

It is the label that is at issue in this calculation

virtual void makVrf::DtMapScaleInstance::setGroup ( float )

protectedvirtual

Sets the overlay group.

Reimplemented from makVrf::DtMapInformationOverlayInstance.

DtMapScaleInstance& makVrf::DtMapScaleInstance::operator= ( const DtMapScaleInstance & rhs )

private

Unimplemented assignment operator.
