David,<br><br>Yes, I noticed this clicking problem with JOSM myself, and it is annoying. Is it Java or just JOSM-specific problem? In OS (Windows at least), the mouse-down and mouse-up events are treated separately, so I don't see why it would be problem if the mouse moves in between.<br>
Anyway, thanks for the info. Looks like I'm going to have to borrow a tablet and test it out with JOSM before buying.<br><br>Igor<br><br><br><div class="gmail_quote">On Mon, Jan 25, 2010 at 12:01 PM, David Earl <span dir="ltr"><<a href="mailto:david@frankieandshadow.com">david@frankieandshadow.com</a>></span> wrote:<br>

</div></div>I did use a tablet at one point, but I gave up. In principle it should<br>
be ideal and it is for most drawing and painting programs, and you<br>
quickly get used to the right button on the pen side and operating menus<br>
with it.<br>
<br>
It's not the tablet that's the problem - an A6 size one is fine. The<br>
problem is Java. It seems to insist that for a mouse click to be<br>
recognized properly the coordinates at the down press have to be the<br>
same as those at the up-press. With a mouse this is a problem sometimes<br>
if you nudge it, but with a tablet it is impossible.<br>
<br>
There is a plugin for JOSM which tries to remedy this (by checking if<br>
the up and down are within a certain distance of each other). It wasn't<br>
right and I hacked it a bit, but it still isn't quite right because<br>
there is often a delay before sensing "mouse" clicks - if you are<br>
creating a way, you frequently click-click-click quite fast along the<br>
track, and JOSM quickly gets behind and the mouse tracking gets<br>
confused. This happens using a mouse as well and is very frustrating,<br>
but it is much worse with a tablet in my experience.<br>
<br>
So I think more could be done in JOSM to work around wjhat are<br>
essentially failings in Java's mouse handling, but it is not that great<br>
at the moment. It's not that you can't use it, you just have to be so<br>
much more deliberate and patient in entering clicks (and you do have to<br>
have the nearclick plugin)<br>
