在水平滚动条上画一条线-C# [英] Draw a line on horizontal scrollbar - C#

问题描述

有什么办法可以在hScrollBar上画一条线(约5像素宽)? 该线将从一端移到另一端.它将代表运动.

Is there any way to draw a line (about 5 pixels width) on hScrollBar ? The line will move from one end to another. It will represent the movement.

推荐答案

我认为这是可能的.您有两个选择-所有者绘制的滚动条(在C ++/MFC中为挂起示例)-

I think its possible. You have two options - an owner drawn scrollbar (an example in C++/MFC to get a hang - http://www.codeproject.com/Articles/14724/Replace-a-Window-s-Internal-Scrollbar-with-a-custo ), the second option is to track the scrollbar movements, draw the line and repaint it.
