SplitContainer.Panel1MinSize 属性
重要

获取或设置拆分器与 Panel1 的左边缘或上边缘的最小距离（以像素为单位）。
public:
property int Panel1MinSize { int get(); void set(int value); };C#
public int Panel1MinSize { get; set; }member this.Panel1MinSize : int with get, setPublic Property Panel1MinSize As IntegerInt32，它表示拆分器离 Panel1 的左边缘或上边缘的最小距离（以像素为单位）。 不管 Orientation 为何值，默认值均为 25 像素。
指定的值与方向不一致。
下面的代码示例显示了垂直拆分器，其中左面板 (最小大小的 Panel1) 设置为 30 像素，现在拆分器可以从容器的左边缘最小距离。 还显示了垂直拆分器的其他基本属性。 此示例是为类提供的大型示例的 SplitContainer 一部分。

使用该 Panel1MinSize 属性可防止拆分器太接近容器的左边缘或上边缘移动。 例如，你可能想要阻止覆盖部分 TreeView 显示区域。
Orientation如果属性Vertical (默认) ，Panel1MinSize则从左边缘Panel1返回拆分器的最低距离（以像素为单位）。 如果属性是OrientationHorizontal，Panel1MinSize则返回从上边缘Panel1的拆分器最小距离（以像素为单位）。
