isVariableWidth	Returns whether the width is variable
maximumValue	Returns the maximum value used to defined the variable width
maximumWidth	Returns the maximum width used to defined the variable width
minimumValue	Returns the minimum value used to defined the variable width
minimumWidth	Returns the minimum width used to defined the variable width
readXml	Reads configuration from the given DOM element
setFixedStrokeWidth	Sets the fixed width
setIgnoreOutOfRange	Sets whether the variable width ignores out of range value
setIsVariableWidth	Returns whether the width is variable
setMaximumValue	Sets the maximum value used to defined the variable width
setMaximumWidth	Sets the maximum width used to defined the variable width
setMinimumValue	Sets the minimum value used to defined the variable width
setMinimumWidth	Sets the minimum width used to defined the variable width
setUseAbsoluteValue	Sets whether absolute value are used as input
strokeWidth	Returns the variable width depending on value, if not varying returns the fixed width
useAbsoluteValue	Returns whether absolute value are used as input
writeXml	Writes configuration to a new DOM element
