PaintSelection メソッド (GradientSelectionRenderer)

選択範囲を描画します。

構文

Visual Basic
C#

'宣言
 
Public Sub PaintSelection( _
   ByVal g As Graphics, _
   ByVal x As Integer, _
   ByVal y As Integer, _
   ByVal width As Integer, _
   ByVal height As Integer _
)

public void PaintSelection( 
   Graphics g,
   int x,
   int y,
   int width,
   int height
)

パラメータ

g: 矩形の描画に使用するGraphicsオブジェクト
x: 描画する矩形の左上隅のx座標
y: 描画する矩形の左上隅のy座標
width: 描画する矩形の幅
height: 描画する矩形の高さ

使用例

次のサンプルコードは、カスタムの選択範囲レンダラを作成します。

public class SelectionRenderer : FarPoint.Win.Spread.GradientSelectionRenderer {
    
    private Color clr1;
    
    private Color clr2;
    
    private System.Drawing.Drawing2D.LinearGradientMode gradMode;
    
    private int op;
    
    public SelectionRenderer(Color color1, Color color2, System.Drawing.Drawing2D.LinearGradientMode mode, int opacity) :

            base(Color.Beige, Color.Blue, Drawing2D.LinearGradientMode.ForwardDiagonal, 220) {
        clr1 = color1;
        clr2 = color2;
        gradMode = mode;
        op = opacity;
    }
    
    public new void PaintSelection(Graphics g, int x, int y, int width, int height) {
        if (((width &gt; 0) 
                    && (height &gt; 0))) {

        }
    }
}
fpSpread1.SelectionRenderer = new SelectionRenderer(Color.Beige, Color.Blue, Drawing2D.LinearGradientMode.ForwardDiagonal,
220);
