public DrawTreeNodeEventArgs(System.Drawing.Graphics graphics, System.Windows.Forms.TreeNode node, System.Drawing.Rectangle bounds, System.Windows.Forms.TreeNodeStates state);C#
public DrawTreeNodeEventArgs(System.Drawing.Graphics graphics, System.Windows.Forms.TreeNode? node, System.Drawing.Rectangle bounds, System.Windows.Forms.TreeNodeStates state);new System.Windows.Forms.DrawTreeNodeEventArgs : System.Drawing.Graphics * System.Windows.Forms.TreeNode * System.Drawing.Rectangle * System.Windows.Forms.TreeNodeStates -> System.Windows.Forms.DrawTreeNodeEventArgsPublic Sub New (graphics As Graphics, node As TreeNode, bounds As Rectangle, state As TreeNodeStates)- state
- TreeNodeStates
TreeNodeStates 值的按位组合，指示要绘制的 TreeNode 的当前状态。
.NET 6 及更高版本： graphics 为 null。
