Description

When you close either window (Click on X), the program crashes, in a normal window manager the window just re-opens on the next frame of playback.

[[CvCapture]]* video = cvCaptureFromFile("../../cube4.avi");
CV_Assert(video);

namedWindow("Input", CV_WINDOW_AUTOSIZE | CV_WINDOW_FREERATIO); 
namedWindow("Output", CV_WINDOW_AUTOSIZE | CV_WINDOW_FREERATIO); 

[[IplImage]]* source = 0;
while(cvWaitKey(33) != 27) 
{ 
    source=cvQueryFrame(video); 
    cvShowImage("Input",source); 
    cvShowImage("Output",source); 
}
cvReleaseCapture(&video);

crashes on this line of code in window_QT (line 1697)

if (global_control_panel->myLayout->count() == 0)
vect_QActionsr9->setDisabled(true);

Hello,

Your are right.

That should be fixed now. However, with this current implementation, the user have to destroy the window at the end (cvDestroyWindow("blabla") or cvDestroyAllWindow()) to be sure the memory is released.
