控制的透明度取決於其母公司控制。您但是,可以使用自定義的容器控件,而不是圖片框父image.and也許這代碼usfull
using System;
using System.Windows.Forms;
using System.Drawing;
public class TransparentControl : Control
{
private readonly Timer refresher;
private Image _image;
public TransparentControl()
{
SetStyle(ControlStyles.SupportsTransparentBackColor, true);
BackColor = Color.Transparent;
refresher = new Timer();
refresher.Tick += TimerOnTick;
refresher.Interval = 50;
refresher.Enabled = true;
refresher.Start();
}
protected override CreateParams CreateParams
{
get
{
CreateParams cp = base.CreateParams;
cp.ExStyle |= 0x20;
return cp;
}
}
protected override void OnMove(EventArgs e)
{
RecreateHandle();
}
protected override void OnPaint(PaintEventArgs e)
{
if (_image != null)
{
e.Graphics.DrawImage(_image, (Width/2) - (_image.Width/2), (Height/2) - (_image.Height/2));
}
}
protected override void OnPaintBackground(PaintEventArgs e)
{
//Do not paint background
}
//Hack
public void Redraw()
{
RecreateHandle();
}
private void TimerOnTick(object source, EventArgs e)
{
RecreateHandle();
refresher.Stop();
}
public Image Image
{
get
{
return _image;
}
set
{
_image = value;
RecreateHandle();
}
}
}
不幸的是,這不會給任何其他想法的預期結果? – 2013-02-16 19:26:59
