OK, I found a dataset that easily reproduces what I think is Benjamin's
mouse wheel zoom redraw anomaly. What seems to be happening is that in
areas where vector redraw takes a few seconds or more, multiple mouse wheel
zooms, separated by more that .7 seconds, do not allow the screen to repaint
Darn. I was noticing the anomaly occurred for me when I accidentally
pressed the mouse wheel button (which initiates a regular zoom in the middle
of a mouse wheel zoom. Part of the difficulty of mouse wheel zoom is that,
unlike the zoom realtime tool, it is not modal and other events can
I have restored zoom to cursor on mouse wheel zoom.

@white space when zooming out:
Maybe you can use the drawing algorithm that draw the geometries like a
pencil sketch when zooming with the slidebar (and then rerender the
geometries at a given time interval).

It reproduces with hand tool. Tested with nightly builds from 23th and 25th
february.

Hi Benjamin,
Could you try to reproduce the anomaly when mouse wheel zooming with the
hand tool please? If it doesn't reproduce, I may know what is
Hi!
I tested the new mouse wheel zoom with the nightly build from 23-Feb-2010
02:12.
(A) In previous versions the zoom function zoomed-in to the current position
of the mouse cursor. The new behavour is, that it just zooms to the position
in middle of the layerviewpanel. I'd like to have the old
Hi Benjamin,
(A) I like the old zoom to mouse position behavior too. I just haven't
gotten the zoom to cursor math right yet.
(B) You might be right. I've noticed an occasional anomaly too, but can't
reproduce it consistently. I don't know what is causing it.

I accidentally reversed the Mouse wheel zoom direction in the last update.
It should now zoom in when the wheel is rolled away from your hand as other
mapping programs do.

the EZ buttons are now added as default (but even hardcoded in
OpenJUMPConfiguration and not the xml file).

More Mouse Wheel Zooming updates. I fixed some problems with mouse wheel
zoom in and zoom out in the same half second causing radical changes. The
Timer period now resets while the wheel is still moving, and I changed the
Timer period to .7 seconds to better reflect actual use.

Hi,
Excellent job. Mouse wheel zooming gives a good feeling because screen
is updating fast and from the server side I can see also that no
unnecessary WMS calls are sent. That gives more speed for OJ user
especially with slow connection to WMS but the feature itself is nice
even without WMS
OK, I have committed an experimental version of AbstractZoomTool that
incorporates a deferred mouse wheel zoom for half a second. It does an
image stretch from the center of the panel until the half second expires.
Please test after tomorrow's nightly build.
Comments?

Hi Jukka,
The behavior you described is what I programmed for the mouse wheel
zooming. I like the idea of doing raster scaling until you stop using the
wheel. It is just a matter of finding time to do it. As you can imagine,
this is fairly difficult code to write, but I believe it to be an

Can you file a feature request on SourceForge so we don't forget this?
