Member Function Documentation

applyChangeJS()

void Wt::WLeafletMap::Circle::applyChangeJS ( WStringStream &  ss, long long  id  )

overrideprivatevirtual

This method should write the JS code needed to update the item. The JS code written can use o.wtObj to refer to the WLeafletMap JS object.

Reimplemented from Wt::WLeafletMap::AbstractDrawnItem.

createItemJS()

void Wt::WLeafletMap::Circle::createItemJS ( WStringStream &  ss, WStringStream &  postJS, long long  id  )

overrideprotectedvirtual

Writes the JS code to create this item to the stream.

This method should write in ss the JS code that creates the item. The postJS stream can be used to write JS code that should be executed after the item has been created.

Implements Wt::WLeafletMap::AbstractMapItem.

radius()

double Wt::WLeafletMap::Circle::radius

(

)

const

Return the radius (in meters).
