[Qt-interest] painting widgets in console applications?

[Daniel Franke]

Hi all.

I implemented a Qt/Qwt-based plotting application to plot particular 
measurement data. The application provides an export functionality to save the 
plotting widget into an image file via QPixmap. All nice and shiny so far.

Now I'd like to run my app from the console and directly export into an image 
file without showing a user interface. Render()'ing the widget directly onto a 
QPixmap works, but still requires some form of window manager to be 
active/accessible (i.e. QApplication(argc, argv, enableGUI=true)). This is 
hardly a constraint if run locally, but if run through ssh, which this is 
meant to, it is: "myplot: cannot connect to X server" - and x11forwarding is 
not always an option. Letting 'enableGUI=false', Qt complains "QWidget: Cannot 
create a QWidget when no GUI is being used".

Is there a solution for this?

Thanks
