Hi,
No, you need not to click on the zoom bar. PageUp and PageDown are active on
the map window, and when pressed there the zoom step is much smaller. I
suppose you are now using the zoom bar that is opened via menu View-Zoombar. I
think that is rather a useless tool, or it just dublicates the top menu zoom
slider features.

Hi,
The other zoom tools are helpful. But specifically I'd like to use the
zoom bar since the zoom bar will zoom with the center unchanged during the
process.
PageUp/down behaves the same in Substance L&F as clicking on either
side of the knob of the tool bar. Plus I have to click on the zoombar to let
the zoombar to receive keyboard events, which adding an extra step. My work on
top of OpenJump is for the very busy CSRs in a call center, so any extra step
will slow then down.
Techies obviously enjoy choices but too many ways to do about same
thing causes confusion to regular call center workers.
Thanks
Bing

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
Bing

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

Any help is appreciated.
