comparison layer/RegionLayer.cpp @ 1537:4f8c72adbf43

Clarify naming of some view-related methods. Rename LayerGeometryProvider::getValueExtents to getVisibleExtentsForUnit, and View::getTextLabelHeight to getTextLabelYCoord. Add View::getVisibleExtentsForAnyUnit to be used to determine which unit to adopt in a new e.g. box layer.

     QString queryUnits;
     queryUnits = getScaleUnits();
 
     if (m_verticalScale == AutoAlignScale) {

+        if (!v->getVisibleExtentsForUnit(queryUnits, min, max, log)) {
 
             min = model->getValueMinimum();
             max = model->getValueMaximum();
 
 //            cerr << "RegionLayer[" << this << "]::getScaleExtents: min = " << min << ", max = " << max << ", log = " << log << endl;
