Hi all
..I am trying to use threads but it is driving me crazy..
In another post here I found an example how to use member function with
osgthreads..
..it works fine if the function is in that class.. but if I try to give a
member function pointer nothig works anymore..
so here is my code :
#include <OpenSG/OSGBaseFunctions.h>
#include <OpenSG/OSGThread.h>
#include <OpenSG/OSGThreadManager.h>
#include <OpenSG/OSGLock.h>
OSG_BEGIN_NAMESPACE;
using namespace std;
template <typename T>
class MyThreadWrapper
{
public:
class MyThread : public Thread
{
private:
T* caller;
void (T::*fkt) (void);
typedef Thread Inherited;
MyThread(const MyThread &source);
void operator =(const MyThread &source);
protected:
Lock *pLock;
static MPThreadType _type;
static Thread *create(const Char8 *szName, UInt32 uiId) {
return new MyThread(szName, uiId);
}
MyThread(const Char8 *szName, UInt32 uiId) :
Inherited(szName, uiId), pLock(NULL) {
//_type = new MPThreadType("MyThread", "Thread",
(CreateThreadF) MyThread::create, NULL);
fprintf(stderr, "Create Lock\n");
fflush(stderr);
pLock = ThreadManager::the()->getLock(NULL);
}
virtual ~MyThread(void){}
void workProc(void) {
while(1) {
cout << "\ntest";
//(caller->*fkt)(void);
osgsleep(100);
}
}
public:
UInt32 _uiThreadId;
static MyThread* get (Char8* szName){
BaseThread *pThread =
ThreadManager::the()->getThread(szName, "MyThread");
return dynamic_cast<MyThread* >(pThread);
}
static MyThread *find(Char8 *szName) {
BaseThread *pThread =
ThreadManager::the()->findThread(szName);
return dynamic_cast<MyThread *>(pThread);
}
void setPipe (T* cl, void (T::*fktPt)(void)) {
caller = cl;
fkt = fktPt;
}
};
};
template <typename T>
MPThreadType MyThreadWrapper<T>::MyThread::_type("MyThread", "Thread",
(CreateThreadF) MyThread::create, NULL);
//MPThreadType MyThreadWrapper::MyThread::_type("MyThread", "Thread",
(CreateThreadF) MyThread::create, NULL);
class OSGPeriphery {
private:
MyThreadWrapper<OSGPeriphery>::MyThread* pThread;
//MyThreadWrapper::MyThread* pThread;
public:
void startThread() {
fprintf(stderr, "Derived Thread Test Started\n");
pThread = MyThreadWrapper<OSGPeriphery>::MyThread::get("My1");
//pThread = MyThreadWrapper::MyThread::get("My1");
pThread->setPipe(this, &OSGPeriphery::update);
if(pThread == NULL)
{
fprintf(stderr, "Could not create thread\n");
}
pThread->_uiThreadId = 1;
pThread->run(1);
}
void update() {
cout <<"\nbla";
}
};
it works fine without the template crap and the setPipe fkt..
I get the following error : "could not find type named :: My1"
..I believe the problem is the MPThreadType.. but I have no idea what is
going on.. (first time I do something like this..)
I am gratefull for any help, thanks for your time,
Victor
