question: the default implementation of this icontributionitem method returns the value recorded in an internal state variable , which is true by default . setvisible should be used to change this setting . concode_field_sep IContributionManager parent concode_elem_sep boolean visible concode_elem_sep String id concode_field_sep void setVisible concode_elem_sep void saveWidgetState concode_elem_sep IContributionManager getParent concode_elem_sep boolean isGroupMarker concode_elem_sep boolean isDynamic concode_elem_sep void update concode_elem_sep void update concode_elem_sep String getId concode_elem_sep void fill concode_elem_sep void fill concode_elem_sep void fill concode_elem_sep void fill concode_elem_sep boolean isDirty concode_elem_sep boolean isEnabled concode_elem_sep void setId concode_elem_sep void dispose concode_elem_sep String toString concode_elem_sep void setParent concode_elem_sep boolean isSeparator
target: boolean function ( ) { return visible ; }
