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

[Forest Yang]

Thanks ! I was too curious about the techniques to forget this simple one.

Just for curious, can we implement the similar thing without "&" ? I
saw this effect from a TCL/TK program and also Acrobat Reader.

One good future usage would be like Acrobat Reader, if there are files
opened, or one acroreader alive, when execute

$ acroread file.pdf

It just open a new tab in the reader and return to shell, even you did
not put a "&" at the end



Forest.
