[vtkusers] wglMakeCurrent failed: Thread error?

[Junior Pilato]

Hi Vtk users!!!!

I'm developing an animation, and I'm using QVTK for
provide user interface..

I'm recentily post this message in Qt-interest lists:
http://lists.trolltech.com/qt-interest/2005-10/thread00210-0.html

And I'm tryed to solver this with QThread (thanks for help..).....but,
again,
I have other problem....

When my application call render() function in my qthread object,
VTK show this message:
vtkWin32OpenGLRenderWindow: wglMakeCurrent failed in... ( sorry,
I can´t read, application crash!)

Wath's wrong???


My code:

class PlayThread : public QThread
{
public:

PlayThread(){ play=true };

void run();

void stop();

void SetAnimator( Animator *ms );

void SetRenderer( vtkRenderer *r );

private:

volatile bool play;

Animator *ani;

vtkRenderer *rthread;
};

/********************/

void PlayThread::run(){

while (this->play)
{
this->ani->StartUpdate();
this->rthread->GetRenderWindow()->Render(); // here occur the error...
 }

this->play = true;
}


void PlayThread::stop(){
this->play = false;
}

.
.
.
/*********************/
// Main widget....
void Viewer::play_simulation(){

if ( !this->play_thread->isRunning() )
this->play_thread->start();
}

void Viewer::stop_simulation(){
if (this->play_thread->isRunning() )
this->play_thread->stop();
}



Does somebody can help me ?

Thanks a lot!!!
