Hi,

I'm a newbie in the Qt - world and I'm starting to use the Qt environment and Qwt. I'm also experimenting that problem.

I'm writting a simple example based on realtime_plot and I get the same runtime error (either in debug or release version) when I execute it. The offending code is this:

MainWindow::MainWindow() : QMainWindow(){

addToolBar(toolBar());

d_plot = new RandomPlot(this); //<--- The error is raised here. d_plot is an object of class RandomPlot.
d_plot->setMargin(4);
setCentralWidget(d_plot);


initWhatsThis();
setAttribute(Qt::WA_DeleteOnClose);
}



I did some research and just found that the problem may be in the classes inheriting from QFrame but I cannot figure out what the problem is. I'm running Qt-Creator 4.6.0 and Qwt 5.2.0.

Regards,


Juan

It's me again!

I think I found a solution to the problem.... I followed these steps (which were already posted in another thread) http://www.qtcentre.org/threads/2617...178#post127178.

Now my first QWT application is up and running.

I hope it can help.


Regards,


Juan.
