示例1:
IvDragger::IvDragger(QtCoinViewerPtr viewer, ItemPtr pItem, float draggerScale)
{
_selectedItem = pItem;
_viewer = viewer;
_scale = draggerScale;
_penv = viewer->GetEnv();
//_ptext = NULL;
// set some default behavioral options
_checkCollision = false;
_prevtransparency = pItem->GetIvTransparency()->value;
pItem->GetIvTransparency()->value = SoGLRenderAction::SCREEN_DOOR;
if( !!pItem &&(pItem->GetIvRoot() != NULL)) {
_GetBounds(pItem->GetIvRoot(), _ab);
// make the item transparent
SoSearchAction search;
search.setType(SoMaterial::getClassTypeId());
search.setInterest(SoSearchAction::ALL);
search.apply(pItem->GetIvRoot());
for(int i = 0; i < search.getPaths().getLength(); ++i) {
SoPath* path = search.getPaths()[i];
SoMaterial* pmtrl = (SoMaterial*)path->getTail();
vtransparency.push_back(pmtrl->transparency[0]);
pmtrl->transparency = 0.25f;
}
_vlinkaxes.resize(pItem->GetNumIvLinks());
for(size_t i = 0; i < _vlinkaxes.size(); ++i) {
_vlinkaxes[i] = _CreateAxes(i == 0 ? 1.0f : 0.25f,0.5f);
pItem->GetIvLink(i)->addChild(_vlinkaxes[i]);
}
}
}示例2: GetSelectedItem
IvDragger::~IvDragger()
{
ItemPtr selectedItem = GetSelectedItem();
if( !!selectedItem &&(selectedItem->GetIvRoot() != NULL)) {
for(size_t i = 0; i < _vlinkaxes.size(); ++i) {
selectedItem->GetIvLink(i)->removeChild(_vlinkaxes[i]);
}
_vlinkaxes.clear();
// revert transparency
SoSearchAction search;
search.setType(SoMaterial::getClassTypeId());
search.setInterest(SoSearchAction::ALL);
search.apply(selectedItem->GetIvRoot());
for(int i = 0; i < search.getPaths().getLength(); ++i) {
SoPath* path = search.getPaths()[i];
SoMaterial* pmtrl = (SoMaterial*)path->getTail();
if( i < (int)vtransparency.size() )
pmtrl->transparency = vtransparency[i];
}
selectedItem->GetIvTransparency()->value = _prevtransparency;
}
