right-click doing line toggle on QT

[<pl...@pi...>]

Hi,

a minor but persistently annoying bug on gnuplot-qt ( as provided by 
Fedora 23 ) :

Fedora provide separate builds for gnuplot  ( aka gnuplot-qt ) and 
gnuplot-wx

On the qt build a right mouse click in the plot area to select a zoom 
area is also triggering the line visibility toggle if it happens on the 
legend part of the graph. This is very annoying since it hides the line 
you may be trying to zoom on making it impossible to accurately choose 
the zoom area.

Clearly this feature should be restricted to left-mouse clicks. This is 
the case in wxt , so I presume that it's an error.




In passing I also report that when qt terminal toggles a line the legend 
gets a mid-grey background colour that is very ugly.  Presumably someone 
thought it could indicated a non-visible line.

I would submit that it just makes a visual mess of the graph and is not 
even helpful since it renders the legend pretty much visible anyway.

Same on wxt but legible.. Probably grey too dark on qt.

I seem to recall that it was the line sample in the legend that got 
turned off along with the line. This communicates the same information 
in an aesthetically more acceptable manner, IMO.


Best regards, Peter.
