Hello,
I want to create a class based upon QwtPlot. I declare it as usual:
Qt Code:
#include <Qwt/qwt_plot.h> Q_OBJECT public: signals: public slots: };To copy to clipboard, switch view to plain text mode
But I get the error:
"During startup program exited with code 0xc0000005".
I know it's an access violation error. But I don't know why it happens only if I create a class derived from QwtPlot. In my application there are several Qwt items and all works fine.
What I should do to find (and fix) the issue?
Thanks in advance
Marco
ps. I get the same behavior if I include the incrementalplot for example
