The following example application implements functions that are called when the application is loaded and unloaded. Its initialization function adds two new commands to AutoCAD: CREATE and ITERATE.
It also initializes the new class AsdkMyClass and adds it to the ObjectARX hierarchy with the acrxBuildClassHierarchy() function. (AsdkMyClass is described in Example of a Custom Object Class.)
// The initialization function called from the acrxEntryPoint()
// function during the kInitAppMsg case is used to add commands
// to the command stack and to add classes to the ACRX class
// hierarchy.
//
void
initApp()
{
acedRegCmds->addCommand("ASDK_DICTIONARY_COMMANDS",
"ASDK_CREATE", "CREATE", ACRX_CMD_MODAL,
createDictionary);
acedRegCmds->addCommand("ASDK_DICTIONARY_COMMANDS",
"ASDK_ITERATE", "ITERATE", ACRX_CMD_MODAL,
iterateDictionary);
AsdkMyClass::rxInit();
acrxBuildClassHierarchy();
}
// The cleanup function called from the acrxEntryPoint()
// function during the kUnloadAppMsg case removes this application's
// command set from the command stack and removes this application's
// custom classes from the ACRX runtime class hierarchy.
//
void
unloadApp()
{
acedRegCmds->removeGroup("ASDK_DICTIONARY_COMMANDS");
// Remove the AsdkMyClass class from the ACRX runtime
// class hierarchy. If this is done while the database is
// still active, it should cause all objects of class
// AsdkMyClass to be turned into proxies.
//
deleteAcRxClass(AsdkMyClass::desc());
