@BeanProperty(expert=true, description="The margin between the tool bar\'s border and contents")
public void setMargin (Insets m)

Sets the margin between the tool bar's border and its buttons. Setting to null causes the tool bar to use the default margins. The tool bar's default Border object uses this value to create the proper margin. However, if a non-default border is set on the tool bar, it is that Border object's responsibility to create the appropriate margin space (otherwise this property will effectively be ignored).

m    an Insets object that defines the space between the border and the buttons
