[Qt-interest] return to command line but the GUI is still alive

[Forest Yang]

Hi

  I am writing a simple code to plot some data with QWT, I want it to
be launched from command line and accept data from a pipe.
After I type the command, the plotting GUI appears, and return the
control to shell. The GUI can stay alive until I click the X button

The standard app.exe() will wait until I send quit() to return to
shell control. But I don't want to wait.

Any thoughts on this ?

Thanks.
