A class that implements this interface has a width specification. This
interface provides access to the width specification without compromising the
ability to provide a mock container instance in JRE unit tests.
Returns the width specification. Values greater than 1 represent width in
pixels. Values between 0 and 1 (inclusive) represent a percent of the width
of the container. A value of -1 represents the default width of the
associated widget. Values less than -1 represent the width of the container
minus the absolute value of the widget width.
Returns:
the width specification
setWidth
void setWidth(double width)
Sets the width specification. Values greater than 1 represent width in
pixels. Values between 0 and 1 (inclusive) represent a percent of the width
of the container. A value of -1 represents the default width of the
associated widget. Values less than -1 represent the width of the container
minus the absolute value of the widget width.
