TTMSFNCDataGridBeforeDrawCellEvent Event Type

Fired before a cell is painted. Set ACanDraw to False to skip the default drawing and take full control via AGraphics.

API unit family: TMSFNCDataGridRenderer

Remarks

Fires on every paint of a visible cell, so keep handlers fast. To only change colours or fonts, prefer OnGetCellLayout.

Name	Description
`Sender`	The grid renderer.
`AGraphics`	Graphics context, already initialised with the fill, stroke and font of the cell layout.
`ACell`	The cell about to be painted; `ACell.Rect` gives its bounds and `ACell.Layout` its resolved layout.
`ACanDraw`	Defaults to True. Set to False to skip the default background and content drawing; the after-draw event is then not fired either.
