PaintCell メソッド (IRenderer)

非編集時のセルを描画します。

構文

Visual Basic
C#

'Declaration
 
Sub PaintCell( _
   ByVal g As Graphics, _
   ByVal r As Rectangle, _
   ByVal appearance As Appearance, _
   ByVal value As Object, _
   ByVal isSelected As Boolean, _
   ByVal isLocked As Boolean, _
   ByVal zoomFactor As Single _
)

void PaintCell( 
   Graphics g,
   Rectangle r,
   Appearance appearance,
   object value,
   bool isSelected,
   bool isLocked,
   float zoomFactor
)

パラメータ

g: セルを描画するグラフィックインタフェース
r: 矩形領域の位置とサイズ
appearance: セルの外観設定
value: オブジェクト（レンダラの名前）
isSelected: セルが選択されているかどうかを表すブール値
isLocked: セルがロックされているかどうか
zoomFactor: セルを描画するときの倍率を表す数値

解説

zoomFactorパラメータの限度については、シートのZoomFactorプロパティを参照してください。

例

次のサンプルコードは、メソッドとイベントの使用方法を説明するため、IRendererクラスをサブクラス化し、スプレッドシート内の最初のセルのカスタムレンダラを作成しています。

C#
Visual Basic

public static CheckBox ck = new CheckBox();

class myRenderer : FarPoint.Win.Spread.CellType.IRenderer
{
  public bool CanOverflow()
  {
      return true;
  }
  public bool CanBeOverflown()
  {
      return true;
  }
  public Size GetPreferredSize(Graphics g, Size s, FarPoint.Win.Spread.Appearance appr, object value, float zoom)
 {
      s = new Size(50, 50);
      return s;
  }
  public void PaintCell(Graphics g, Rectangle r, FarPoint.Win.Spread.Appearance appr, object value, bool issel, bool islocked,
float zoom) 
  {
      string s;
      ck.CheckState = CheckState.Checked;
      s = ck.CheckState.ToString();
      Font f = new Font("MS Sans Serif", 10);
      appr.BackColor = Color.Red;
      appr.ForeColor = Color.Yellow;
      appr.Font = f;
      Brush b, b1;
      b = new SolidBrush(appr.BackColor);
      b1 = new SolidBrush(appr.ForeColor);
      g.FillRectangle(b, r);
      g.DrawString(s, appr.Font, b1, r);
      b.Dispose();
      b1.Dispose();
      }
}

private void Form1_Load(object sender, System.EventArgs e)
{
      fpSpread1.ActiveSheet.Cells[0, 0].Renderer = new myRenderer();
}

      g.DrawString(s, appr.Font, b1, r.X, r.Y)
      b.Dispose()
      b1.Dispose()
End Sub
