TcxGridChartDiagram.OnCustomDrawLegendItem Event
Occurs every time a legend item is about to be drawn.
Declaration
property OnCustomDrawLegendItem: TcxGridChartDiagramLegendItemCustomDrawEvent read; write;
Remarks
The OnCustomDrawLegendItem
event occurs every time a legend item (a legend key and its description, i.e. the display text of the series that corresponds to the legend item) 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 legend item). Sender is usually the element that caused the repaint. The ADone parameter’s value is initially False
. Set it to True
to prevent the grid control from performing default drawing painting over the custom painting performed.
Note
The Chart View’s OnCustomDrawLegendItem event can override the diagram’s OnCustomDrawLegendItem
event since the former occurs after the latter.
