The "zoom" documentation says:

 Zooming is usually accomplished by holding down the left mouse button and
 dragging the mouse to delineate a zoom region.  Some platforms may require
 using a different mouse button.  The original plot can be restored by typing
 the 'u' hotkey in the plot window.  The hotkeys 'p' and 'n' step back and
 forth through a history of zoom operations.

 The option `zoomcoordinates` determines if the coordinates of the zoom box are
 drawn at the edges while zooming. This is on by default.

 If the option `zoomjump` is on, the mouse pointer will be automatically
 offset a small distance after starting a zoom region with button 3. This can
 be useful to avoid a tiny (or even empty) zoom region. `zoomjump` is off by
 default.

But holding down any mouse button doesn't have any effect in the 'qt'
terminal. And the zoom buttons and the hotkeys don't have any effect
either.

Hi,

you help will be much more effective, if you report all of this bugs directly to
upstream instead of Debian BTS. I am sure, all of them are not Debian-specific,

If you do really want to see them fixed, please, do it.

Thank you,

Anton

This was in my TODO list, but I didn't have the time. I'll do that.
In the mean time, since wxt is no longer supported, I'm closing
bug 711142.

Upstream here (sfeam@users.sourceforge.net)

Mousing and zoom has always worked fine in the qt terminal.
The only mousing-related bug in our tracker was that
left-mouse click did not terminate a "pause mouse" command.

I wonder if you are seeing the effect of something else.
For example, there are certain states of the main program
during which mousing is disabled.   Could you please give
a more detailed desciption of the sequence of commands and
mouse actions that you are using to test with?

Like bug 711139, this problem with the 'qt' terminal only occurs
after the main gnuplot program has terminated, in -persist state,
e.g. with

$ GNUTERM=qt gnuplot -persist <<EOF
plot '-' using 1:2 t '' with line
0 0
10 10
e
EOF
