TcxGridChartView.OnCustomDrawLegend Event

Occurs when a chart legend within the View needs to be painted.

Declaration

property OnCustomDrawLegend: TcxGridChartLegendCustomDrawEvent read; write;

Remarks

The OnCustomDrawLegend event occurs every time a chart legend’s area within the View needs to be painted. As with other custom draw events it provides a canvas for the grid control (the ACanvas parameter), ViewInfo (the AViewInfo parameter and its Bounds property) to get the bounding rectangle of the painted element (in this case the chart legend). Sender is usually the element that caused the repaint. The ADone parameter’s value is initially False. Set it to True to tell the grid that you have chosen to custom draw the chart legend.

Note

The Chart View’s OnCustomDrawLegend event can override the diagram’s OnCustomDrawLegend event since the former is fired after the latter.
