Hi,
 
I think that clicking to the left or right from the zoom slider gives rather 
limited impression of the OpenJUMP zooming possibilities.  In addition to that 
it is possible to
- drag the slider to the left or right and get what ever zoom level
- press Page Up and Page Down keys to get small zoom steps (this might be what 
you are after)
- use Zoom In/Out tool and left/right click to get bigger steps
- use Zoom In/Out tool and mouse wheel to get smaller steps
- get the Zoom In/Out tool function into use anytime by using keyboard Alt as a 
shortcut
- use the Zoom realtime tool

        Hi Larry,
         
        I did some research and it turned out that the step size is controlled 
by the BasicSliderUI behind JSlider (I'm using Substance L&F) in my case and 
move 1/10 of the total value range. In case of metal L&F it jumps by one unit. 
I don't know if there is a simple way of configuring that. 
         
         
        Regarding the use of logarithmic scale: Google map uses 18 levels of 
zooming with each level doubling the resolution of the previous one. It can 
cover from the entire earth surface to the street level, sufficient in most 
cases. In my case I'm doing a advanced restaurant search tool often I feel the 
OpenJUMP zooming jumps a little too fast. I think if I can find how to set the 
"step size" of the JSlider then I have the control. 
         
        Any Swing insight here? 
         
         
        Thanks

        Hi Bing,
        
          I'm not sure if the zoom bar can display the full range of zooms if 
the step size is only 2.  It is kind of like a logarithmic scale.  The zoom 
bar's purpose is to provide a fast way of making gross changes in zoom levels, 
and to display the current zoom level's order of magnitude.  The usual way of 
zooming by a factor of two is to use the zoom tool, either by explicitly 
selecting it, or by using a quasimode modifier key (Alt).  A more dynamic zoom 
capability is available with the Zoom Realtime tool (use left and right mouse 
drag to reposition and zoom at the same time).
        
        regards,
        Larry

                I'd like to change the step size of the zoombar from 10 to 2 
for example. Currently the zoom level change by an order of magnitude when I 
click on either side of the knob. I couldn't figure this out. 
                 
                Any help is appreciated.
