I am having this error flood my terminal and make it impossible to debug. Is there a way to silence this warning? This error only generated when I included a scrollToBottom() on my TableWidget.
You should better design your code to avoid displaying this message. If you created the pixmap in another thread and "use" it in the GUI thread this might work now, tomorrow or forever ... or will not. Don't do that.
You cannot suppress the output of this warning without changing the Qt sources or installing a message handler.
