ginput problem with qt

[Petri Piila]

Hi,

There seems to be some problem when using ginput with graphics toolkit qt. 
Right after plotting, [x,y] = ginput(1) produces correct result. After window 
has been resized or zoomed, ginput does not return after you press enter and 
x,y are then empty. In fltk, ginput works also after resizing or zooming.

I’m using octave 4.4.1 and my system is Ubuntu 18.04. I have noticed same 
problem also in macOS Mojave (macports).

Any ideas?
