TcxGridRowLayoutCustomDrawEvent Type

The custom draw procedural type for a row layout.

Declaration

TcxGridRowLayoutCustomDrawEvent = procedure(Sender: TcxGridTableView; ACanvas: TcxCanvas; AViewInfo: TcxCustomGridCellViewInfo; var ADone: Boolean) of object;

Parameters

Name	Type	Description
Sender	TcxGridTableView	The grid Table View that raised the event.
ACanvas	TcxCanvas	The target Table View’s canvas.
AViewInfo	TcxCustomGridCellViewInfo	Contains the target row’s ViewInfo information.
ADone	Boolean	Assign True to this parameter if you override the built-in draw routine. Do not change the parameter value if you only need to complement the built-in draw routine with custom draw operations.

Remarks

The following OnCustomDrawRowHotTrack event handler changes the default background color of selected rows to green:

Delphi

procedure TForm1.cxGrid1TableView1RowLayoutCustomDrawRowSelection(
  Sender: TcxGridTableView; ACanvas: TcxCanvas;
  AViewInfo: TcxCustomGridCellViewInfo; var ADone: Boolean);
begin
  ACanvas.Brush.Color := clMoneyGreen;
  ACanvas.FillRect(AViewInfo.Bounds);
  ADone := True;
end;

C++

void __fastcall TForm1::cxGrid1TableView1RowLayoutCustomDrawRowSelection(
  TcxGridTableView *Sender, TcxCanvas *ACanvas,
  TcxCustomGridCellViewInfo *AViewInfo, bool &ADone)
{
  ACanvas->Brush->Color = clMoneyGreen;
  ACanvas->FillRect(AViewInfo->Bounds);
  ADone = true;
}

The following events of row layout settings reference the TcxGridRowLayoutCustomDrawEvent procedure type:

• OnCustomDrawRowBackground
• OnCustomDrawRowHotTrack
• OnCustomDrawRowSelection
