[GiDlist] Mouse wheel zoom pan

[Andrea Calaon]

Hi GiD developers,
I use GiD as geometry modeller as well, and I think some change
in the mouse wheel events use could improve a lot the usability,
speed and reliability of GiD modelling.
Autocad allows a configuration that makes “screen drawing” very
similar to paper drawing even without huge screens.
It is the possibility to use
* the mouse wheel rotation as a “zoom” centred on the
cursor (with a settable ZOOMFACTOR) and
* the mouse wheel buttondown and buttonup events as
activation and deactivation of “pan”.
In this way practically no use of zooming windows is needed
(time efficiency) and the picking of points, lines
is more
reliable since the user never lose sight of the entities. The whole
becomes similar to the continuous going near the paper with your
head for picking points and getting away from the surface when
drawing the lines in “real” paper drawing.
I hope this suggestion will help you in the improvement of you
already powerful program.
Regards
