public class ScaleWidget
- extends Composite
A widget displaying the map's scale, that is the amount of real-world
distance units (such as kilometers) in a certain amount of pixels.
The style name of the widget is map-ScaleWidget
. The style name
of the element that displays the scale size (the ruler) is
map-ScaleWidgetSize
. The style name of the label that displays
the size label is map-ScaleWidgetText
. The actual size label
is implemented using two labels - a background and a foreground one (offset
by one pixel to the right and to the bottom). Their style names are
map-ScaleWidgetBackgroundLabel
and
map-ScaleWidgetForegroundLabel
.
In order to properly use this widget's default look, you need to import the
"widgets/scale/scale.css" file into the page's CSS.
