示例1: addSymbol
//------------------------------------------------------------------------------
// addSymbol() - adds a symbol to our array list;
// -- return the symbol's index; range [ 1 .. getMaxSymbols() ]
// or zero if not added.
//------------------------------------------------------------------------------
int SymbolLoader::addSymbol(const int nType, const char* const id, int specName)
{
int idx = 0;
if (templates != 0) {
// Find the graphic template for this type symbol, and make
// sure that the template is a BasicGL::Graphic, since it
// will be use as the symbol's graphical component.
Basic::Pair* tpair = templates->getPosition(nType);
if (tpair != 0) {
BasicGL::Graphic* tg = dynamic_cast<BasicGL::Graphic*>(tpair->object());
if (tg != 0) {
// Find an empty symbol slot in our master symbol table
for (int i = 0; i < MAX_SYMBOLS && idx == 0; i++) {
if ( symbols[i] == 0 ) {
// Create a new SlSymbol object to manage this symbol.
symbols[i] = symbolFactory();
// Clone the graphic template and set it as the
// symbol's graphical component.
Basic::Pair* newPair = tpair->clone();
BasicGL::Graphic* newGraph = (BasicGL::Graphic*)(newPair->object());
// Set the new graphical component's select name
GLuint mySelName = 0;
if (specName > 0) mySelName = specName;
else mySelName = BasicGL::Graphic::getNewSelectName();
newGraph->setSelectName(mySelName);
// Add the symbol's graphical component to our component list.
{
Basic::PairStream* comp = getComponents();
Basic::Component::processComponents(comp, typeid(BasicGL::Graphic), newPair);
if (comp != 0) comp->unref();
}
// Set the symbol's graphical component pointer
symbols[i]->setSymbolPair( newPair );
newPair->unref(); // symbol[i] now owns it.
// Set the symbol's type and ID.
symbols[i]->setType( nType );
symbols[i]->setId( id );
// And this is the new symbol's index
idx = (i + 1);
}
}
}
}
}
return idx;
}示例2: setSymbolType
//------------------------------------------------------------------------------
// setSymbolType() - change an existing symbol type to another type
//------------------------------------------------------------------------------
bool SymbolLoader::setSymbolType(const int idx, const int nType)
{
bool ok = false;
// Find the symbol
if (idx >= 1 && idx <= MAX_SYMBOLS) {

// sure that the template is a BasicGL::Graphic, since it
// will be use as the symbol's graphical component.
if (templates != 0) {
Basic::Pair* tpair = templates->getPosition(nType);
if (tpair != 0) {
BasicGL::Graphic* tg = dynamic_cast<BasicGL::Graphic*>(tpair->object());
if (tg != 0) {
// Get the symbol's old graphical component
Basic::Pair* oldPair = (Basic::Pair*) symbols[i]->getSymbolPair();
BasicGL::Graphic* oldG = (BasicGL::Graphic*) (oldPair->object());
// Clone the new graphical component from the template
Basic::Pair* newPair = tpair->clone();
// Set the new graphical component's select name using the old's
BasicGL::Graphic* newGraph = (BasicGL::Graphic*) newPair->object();
GLuint mySelName = oldG->getSelectName();
newGraph->setSelectName(mySelName);
// Add the new and remove the old components from our subcomponent list
{
Basic::PairStream* comp = getComponents();
Basic::Component::processComponents(comp, typeid(BasicGL::Graphic), newPair, oldG);
if (comp != 0) comp->unref();
}
// Set the symbol's graphical component pointer
symbols[i]->setSymbolPair( newPair );
newPair->unref(); // symbol[i] now owns it.
// Set new type
symbols[i]->setType( nType );
ok = true;
