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, AddShadow
并在处理窗体 Paint 的事件时调用 方法。 验证窗体是否包含 ListBox 名为 listBox1
的 。
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.

// Create a custom brush using a semi-transparent color, and
// then fill in the rectangle.
