PowerTools SPREAD for Windows Forms 10.0J
CanBeOverflown メソッド (IRenderer)


隣のセルが一杯になったときに内容をこのセルに表示できるかどうかを決定します。
構文
'Declaration
 
Function CanBeOverflown() As Boolean
'使用法
 
Dim instance As IRenderer
Dim value As Boolean
 
value = instance.CanBeOverflown()
bool CanBeOverflown()

戻り値の型

Boolean:一杯になった隣のセルの内容をこのセルに表示できる場合は True、それ以外の場合は False
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。
public static CheckBox ck = new CheckBox();

 {
      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)
