PaintCell(Graphics,Rectangle,Appearance,Object,Boolean,Boolean,Single) メソッド

指定されたグラフィックインタフェースと指定された外観設定を使用して、編集モードでないセルを描画します。

構文

Visual Basic
C#

'Declaration
 
Public Overloads MustOverride Sub PaintCell( _
   ByVal g As Graphics, _
   ByVal r As Rectangle, _
   ByVal appearance As Appearance, _
   ByVal value As Object, _
   ByVal isSelected As Boolean, _

'使用法
 
Dim instance As BaseCellType
Dim g As Graphics
Dim r As Rectangle
Dim appearance As Appearance
Dim value As Object
Dim isSelected As Boolean
Dim isLocked As Boolean
Dim zoomFactor As Single
 
instance.PaintCell(g, r, appearance, value, isSelected, isLocked, zoomFactor)

public abstract void PaintCell( 
   Graphics g,
   Rectangle r,
   Appearance appearance,
   object value,

   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

isLocked: セルがロックされているかどうか
zoomFactor: セルの表示倍率を表す数値

例

次のサンプルコードは、メソッドの使用方法を説明するためにチェックボックスセル型をサブクラス化していますが、他のセル型でも同じように使用できます。

class myCkBox  : FarPoint.Win.Spread.CellType.CheckBoxCellType
{
CheckBox ckbx = new CheckBox();

public myCkBox()
{
}
new event EventHandler EditingCanceled;
new event EventHandler EditingStopped;

public override void StartEditing(EventArgs e, bool selectAll, bool autoClipboard)
{
   return;
}
public override void CancelEditing()
{
   EditingCanceled(ckbx, EventArgs.Empty);
   base.FireEditingCanceled();
}
public override bool StopEditing()
{
   if (EditingStopped != null)
   {
      EditingStopped(ckbx, EventArgs.Empty);
      base.FireEditingStopped();
      return true;
   }
   else
   {
      return false;
   }
}

   }
   else if (ckbx.CheckState == CheckState.Unchecked)
