Public bug reported:
The code is quite simple. A gui with a button. When button is clicked
call the opencv's cvNamedWindow(..) method!.. I made some search on the
net but could not find adequate information.
My computer's configuration is
$uname -a
Linux programex 2.6.22-14-generic #1 SMP Sun Oct 14 21:45:15 GMT 2007 x86_64
GNU/Linux
The Code
------------
#include "denemewindow.h"
DenemeWindow::DenemeWindow(QWidget* parent):QMainWindow(parent)
{
setupUi(this);
connect(pushButton, SIGNAL(clicked()), this, SLOT(showOpenCVWindow()));
}
DenemeWindow::~DenemeWindow()
{
}
void DenemeWindow::showOpenCVWindow()
{
cvNamedWindow("opencv", 1); //this call results the program to crash :S
}
