Hello In the past, there existed two different distributions Octave for windows. The one is octave build by MSVC (maintainer Michael Goffioul) and the other is octave built by MInGW (maintainer Benjamin Lindner).
The jhandle package is developed by Michael Goffioul and it was bundled with the octave for windows distribution built by MSVC. Howeever, unfortunately, the distribution of the octave by MSVC was stopped by the license issue of the between GPL and Microsoft License. So the current distribution of octave for windows is now only distributed by Benjamin Lindner, which is built by MinGW complier. This distributions have not included the jhandle package since the distribution of octave 3.0.2. Therefore it is not surprising that there is no Jhandle in current windows distribution of octave. In the sense of mouse zooming in 2D plot is possible and rotation of 3d plot is also possible is the current gnuplot backend. For mouse zooming by 2d plot it can be made by dragging area by pressing the right mouse button. The rotation of 3D plot is possible by pressing the left button of the mouse and move the mouse. The rotation can be possible by right, left, up and down keys on the keyboard. It is theoretically possible to build jhandle package on the octave built by mingw. This was already posted on the thread http://www.nabble.com/Octave-3.2.0-mingw-jhandles-to24024734.html#a24030423 If you would like to use the jhandle, please try according to Micheal's suggestion on the above thread. However it is hard work, I suppose. Qt octave is completely independent project from the octave and octave-forge project so that I cannot say anything about it. Personally the distribution of the binary bundled with octave 3.0.0 by Michael should be stopped because of the license issue. However, it depends completely on the Qt Octave team. The above stories are the all I can reply to your inquiry. I hope that someone will challenge to build the jhandle package on octave on MInGW and will tell the success stories here. I myself have been using gnuplot backend so far and do not want to challenge it.
