推荐答案

一种方法要做的就是让一个类变量独立地保持拆分器的当前位置，并带有一个标志来指示鼠标按钮是否按下:

One way to do it is to have a class variable to independantly hold the current position of the splitter and a flag to indicate if the mouse button is down:

int split_distance = 150;
bool mouse_down = false;

然后将以下事件处理程序添加到拆分容器中:

Then add the following event handlers to the split container:

private void splitContainer1_Layout ( object sender, LayoutEventArgs e )
{
     this.splitContainer1.SplitterDistance = this.split_distance;
}

private void splitContainer1_MouseDown ( object sender, MouseEventArgs e )
{
     this.mouse_down = true;
}

private void splitContainer1_MouseUp ( object sender, MouseEventArgs e )
{
      this.mouse_down = false;
}

private void splitContainer1_SplitterMoving ( object sender, SplitterCancelEventArgs e )
{
       if ( this.mouse_down )
       {
           this.split_distance = e.SplitX;
       }
}

FixedPanel属性允许将一个面板设置为在调整SplittContainer的大小时不更改其大小.

The FixedPanel property allows setting one panel not to change size when the SplittContainer is resized.
