在树视图节点文本上的提示 [英] Hint on treeview node text

问题描述

树视图节点文本上是否有提示属性?

Is there a hint property on treeview node text?

推荐答案

您为树视图的ToolTip.Popup创建事件处理程序:

You create an event handler for ToolTip.Popup of the treeview:

private void ToolTip1_Popup(Object sender, PopupEventArgs e)

在此事件处理程序中，您将检索鼠标的当前位置，以便确定当前在其下的注释:

In this event handler you retrieve the current position of the mouse so you can determine the note that''s currently under it:

Point pt = PointToClient(Form.MousePosition);
TreeNode node = this.GetNodeAt(pt.X, pt.Y);

没有节点，可以设置工具提示文本并像什么都没有发生一样处理事件:

Not you have the node and can set the tooltip text and handle the event like nothing happend:

e.DrawBackground();
e.DrawBorder();
e.DrawText();
