The Overview pane displays a representation of the current
map that enables you to navigate to a part of it that is of particular
interest, and display it in the Map Builder main
window. This is done by clicking on and dragging the rectangle to
the position of interest in the Overview pane, and then releasing
the mouse button.
You can choose which map layer you want to display in
the Overview pane by setting the
Visible in Overview
property
for each layer, see
Using the map style property sheet.
This prevents cluttering of the pane.
A zoom in/zoom out slider is provided to the right of
the Overview pane. Moving the slider pointer will zoom in or out constantly
until the user releases it. Zooming speed increases with the distance
of the slider from the center point.
The following figure shows an example of the Overview
pane.
