示例
下面的代码示例使用以下成员将阴影添加到 ListBox :
此示例旨在与 Windows 窗体一起使用。 若要运行此示例,请将此代码粘贴到窗体中,并在处理窗体的 Paint 事件时调用 AddShadow
方法。 验证窗体是否包含名为 ListBox 的 listBox1
。
private:
void AddShadow( PaintEventArgs^ e )
{
// Create two SizeF objects.
SizeF shadowSize = listBox1->Size;
SizeF addSize = SizeF(10.5F,20.8F);
// Add them together and save the result in shadowSize.
shadowSize = shadowSize + addSize;
// Get the location of the ListBox and convert it to a PointF.
PointF shadowLocation = listBox1->Location;
// Add two points to get a new location.
shadowLocation = shadowLocation + System::Drawing::Size( 5, 5 );
// Create a rectangleF.
RectangleF rectFToFill = RectangleF(shadowLocation,shadowSize);
// Create a custom brush using a semi-transparent color, and
// then fill in the rectangle.
Color customColor = Color::FromArgb( 50, Color::Gray );
SolidBrush^ shadowBrush = gcnew SolidBrush( customColor );
array<RectangleF>^ temp0 = {rectFToFill};
e->Graphics->FillRectangles( shadowBrush, temp0 );
// Dispose of the brush.
delete shadowBrush;
}
private void AddShadow(PaintEventArgs e)
{
// Create two SizeF objects.
SizeF shadowSize = listBox1.Size;
SizeF addSize = new SizeF(10.5F, 20.8F);
// Add them together and save the result in shadowSize.
shadowSize = shadowSize + addSize;
// Get the location of the ListBox and convert it to a PointF.
PointF shadowLocation = listBox1.Location;
// Add two points to get a new location.
shadowLocation = shadowLocation + new Size(5, 5);
// Create a rectangleF.
RectangleF rectFToFill =
new RectangleF(shadowLocation, shadowSize);
// Create a custom brush using a semi-transparent color, and
// then fill in the rectangle.
Color customColor = Color.FromArgb(50, Color.Gray);
SolidBrush shadowBrush = new SolidBrush(customColor);
e.Graphics.FillRectangles(shadowBrush, new RectangleF[]{rectFToFill});
// Dispose of the brush.
shadowBrush.Dispose();
}
Private Sub AddShadow(ByVal e As PaintEventArgs)

Dim shadowSize As SizeF = Size.op_Implicit(listBox1.Size)
Dim addSize As New SizeF(10.5F, 20.8F)
