71b0638251
- added include for <vector>
qgis.h:
- added WKBUnknown to enumerated list to be used as error state
qgisapp.cpp:
- fixed a for loop
qgisapp.h, qgisiface.h, qgslegend.h, qgslegenditem.h, qgsmapcanvs.h, qgsvectorlayer.h:
- made copy ctor and assignment operator private since we won't be copying
any of these
qgsattributetable.cpp, qgsrasterlayer.cpp, qgssymbologyutils.cpp:
- functions that say they return something should actually return something
*renderer.h:
- made dtors virtual
qgscoordinatetransform.h:
- added initializer for xMax
qgsgeomtypedialog.cpp:
- added return of WKBUnknown when given bad data
qgslabel.cpp, qgslabeldialog.cpp:
- used static_cast to stomp compiler warning
qgsmapcanvas.cpp:
- made CanvasProperties a class form struct, partly to find work-around for
gcc bug and partly to ensure that ctor and assignment operator were
disabled
- ensured that members were in the same order in initializer list as they
were declared
- now use QgsScaleCalculator::units
qgsproject.cpp:
- now read and write map units; still need to tie it in with more code
qgsprojectproperties.cpp:
- now use canonical map units stored in QgsProject singleton object
qgsscalecalculator:
- now prefer to use QgsScaleCalculator::units instead of int
And many minor formatting changes.
