Details:

A good deal of the time using ginput() with the Qt toolkit returns 1 less
button press than was actually made.  Sample code


./run-octave -f --no-gui
graphics_toolkit qt
sombrero
x = ginput
# Now click 3 times on various places on figure
# Type <RETURN> to stop ginput
# Check number of button inputs recorded in x


It "seems" that the first button click merely goes to making the figure window
have the focus.  However, I have sometimes got it to the point where no click
is ever return ([]) despite multiple clicks.
