TRSCustomChartPanel.Listeners Property

Scroll Prev Top Next More

Maintains a list of    IChartPanelListeners that are interested in changes to the chart panel. The TRSCustomChartPanel control will call the Listeners' methods as changes (adding, deleting, and modifying charts and chart values) occur in the control.

alert_noteNotes to Implementers

Add your class (that implements the IChartPanelListener interface) to this list in order to receive chart and chart value changes without using the regular events. The TRSLegendListBox and TRSChartFunction classes use this mechanism to listen to the chart panel without tieing up the event handlers (leaving them free for users)
