奇怪现象： 程序最大化后，快速拖动分割条，图片有时候不能正常显示.... 简单程序，看原程序。

帮你顶

[OriesMap]

你是什么版本的.net呀？
我是2003版的，试了几次，感觉没有什么问题呀？

[karykwan]

private Image imx;
楼主为什么不把image换成pictureBox组件不是要好控制一些

[canoe_eyes]

to oriesMap 我的也是2003，你来回快速拖放分割条，。。。
to karykwan(独行者) 我现在试试你的方法，不过为什么image 不可以呢？

[karykwan]

因为pictureBox好控制一点

[OriesMap]

不好意思，还是没有见到有什么问题。

[canoe_eyes]

to oriesMap 我这边很明显的，奇怪... 把你的程序发给我在这边试试 ,谢谢。[e-mail]

[51106354]

我也试了一下,没有发现什么问题呀!!!
我的版本是2003

[canoe_eyes]

在sizechanged中如果 不重新调整 treeview的size就不会有问题...大家有兴趣可以试试...很奇怪...
private void panel1_SizeChanged(object sender, System.EventArgs e)
{
this.treeView1.Size = new Size (this.panel1.Size.Width - 4, this.panel1.Size.Height -25);
this.panel1.Invalidate();
}

[canoe_eyes]

我用 SnagIt 做了一个这个程序奇怪现象演示的 avi .大家有兴趣可以留下 email。 哦 我一直在线....

[xinbin1122]
