FlowChartX cannot detect changes made to some objects and cannot redraw automatically the diagram items affected by these changes. E.g. changing the size or style of a Box.Font object cannot be detected by FlowChartX because there is only the code of the OLE Font implementation executing. In such situations, use the Repaint method to repaint the whole diagram after the required changes are complete.
