Hi Marco, great you're making progress - you asked:
(1) is "api.openoffice.org" the right place where to look for API documentation ?
Yep.
(2) what is the difference between: XShape, SdrObject (and derived classes) and Graphic ? Which are their roles ?
XShape is an interface, SdrObject the actual representation of that model - it is facaded towards XShape via SvxShape.
(3) what is the GDIMetafile associated with an object of type Graphic ? (and what are MetaActions ?)
It's like a Windows Metafile (WMF) - a list of "drawing" actions, recorded from rendering that shape. MetaActions are the atomic drawing primitives, i.e. set a color, draw a polygon, render some text etc.
(1) OutputDevice::LogicToLogic( rSize100thmm, MAP_100TH_MM, aMapMode )
Yep, that's sadly missing documentation - would be wonderful if you could add doxygen-style inline documentation to the header files, whenever you encounter such omissions. In this case, it's a conversion between coordinate systems (see vcl/outdev.hxx for the prototypes): rSize100thmm is converted from the "MAP_100TH_MM" coordinate system (i.e. one unit is a hundreth of a millimeter) to the aMapMode coordinate system.
(2)
xDrawPages->getByIndex( nDefaultPage ) >>= mxDefaultPage;
if( mxDefaultPage.is() )
{
SvxDrawPage* pSvxDrawPage = SvxDrawPage::getImplementation(
mxDefaultPage );
if( pSvxDrawPage )
{
mpDefaultSdrPage = pSvxDrawPage->GetSdrPage();
mpSdrModel = mpDefaultSdrPage->GetModel();
if( mpSdrModel )
{
SdrOutliner& rOutl = mpSdrModel->GetDrawOutliner(NULL);
maOldFieldHdl = rOutl.GetCalcFieldValueHdl();
rOutl.SetCalcFieldValueHdl( LINK( this, SVGFilter,
CalcFieldHdl) );
}
}
}
What's your concrete question? ;) Cheers, -- Thorsten
