virtual

Returns the combined list of global application and local model data.

virtual void DtTMArea::setUpdateOnTick ( bool  b )

virtual

Set the fact that this area will also refresh its display on a tick.

This needs to be set in instances where something changes the area that the area does not know about

virtual void DtTMArea::markForUpdate ( const QVector< DtModelKey > &  , bool  emitSignal = true  )

virtual

Copy the model data from the supplied list to our internal update list that will be updated on the next call to updateAllSymbols.

virtual void DtTMArea::markForUpdate ( DtModelDataIter *  iter, bool  emitSignal = true  )

virtual

virtual void DtTMArea::markForUpdate ( const DtModelData &  data, bool  emitSignal = true  )

virtual

Reimplemented in DtTerrainMapArea.

virtual void DtTMArea::removeFromUpdate ( DtModelDataIter *  iter )

virtual

Set to true to call updateBackground on next tick.

void DtTMArea::setNextTickIsRepaint ( bool  b )
