Plotting window (Jhandle) in 3.0 under Vista

[Puckja]

I have seen some positive report on trying Octave under vista so I did it.  The installation went smoothly and the Jhandle is chosen in the installation.  I did not add any additional packages.

When I plot a simple curve, the figure window initially shows up with the menu bar at the upper left corner of the screen, and then the "menu" bar is missing as the curve showed up.  There is a time delay in between which may be due to the slow processor/GPU.  The problem is that the figure window did not refresh right and behave strangely.  

If I moved the window to center, the "frame" will stay there, but the "content" will be showed up again at the upper left corner.  

If I try to zoom in with mouse click, the click location is registered higher (about 100 pixels), but it was zoomed correctly.

Sometimes, the figure content will not show up (instead, the content at the background window shows up), but I can minimize/restore the figure window, and then the content will be displayed (again at the upper left corner of my screen).

I did not experience this with my other XP machine (Java 1.5.0.11).  This Vista machine is running Java 1.5.0.14.  BTW, this machine is a so-called UMPC (Fujitsu U810), the processor is Intel A110 with Intel 945GM Express chipset.  I hope the hardware is not the limiting factor.

Could someone show me how can I switch to gnuplot to test out the source of the problem?

BTW, the console window cannot be resized by dragging its corner, but it may not be related.

Thank you for your help.

I'm afraid it is....
I don't have these problems and it looks like the combination of Java, OpenGL
and Vista is not working properly. The windows management as well as
the OpenGL context management is handled by Java/JOGL, so the
problem you have is probably out of the control of octave/JHandles.
The only advise I can give you is to make sure you're using the latest
version of all components:
- install Java-1.6
- check your drivers (by googling a little bit, I found this page
http://www.pc.ro/support/graphics/intel945gm/sb/CS-021517.htm)

Edit the file <octave>\share\octave\3.0.0\m\startup\__default_graphics__.m
and make it return "gnuplot" instead of "jhandles".

Under XP, you can change the console properties by clicking in the title
bar icon (upper-right corner) and choosing "Properties". The console
properties are not controlled by octave.

Hi Michael

I would like to write the note to use jhandle as graphic backend on my web
and octave-forgeWiki.
I think that the jhandle requires the Sun Java version >= 1.6 for Octave-3.0.0(MSVC).
Is that all required ?

OHTH, for MSVC 8 problem, I will make to the link in my web of  
"FW:Re: note for mkoctfile for MSVC (MSVC2008)" on Nabble.

You also need JOGL, but it's included in the binary package. As external
dependency, only Sun JRE is required (should work with 1.5, but it's
better to use 1.6).
