如何在Windows窗体上显示标尺? [英] how can i show a ruler on my windows form?

问题描述

为了显示模拟，我想在表格上放一把尺子.

For showing simulation, i want to put a ruler on my form. is there any tool avalaible or i have to put an image of ruler?

推荐答案

据我所知，标尺只是视觉元素.通过System.Windows.Forms.Control的子类来实现，重写其OnPaint方法进行渲染，根据父控件的大小进行渲染，在调整大小时调用Ruler实例的System.Windows.Forms.Control.Invalidate，演示选项修改以及所有其他事件，其中此控件的循环应更改.

请参阅 http://msdn.microsoft.com/en-us/library/system .windows.forms.control.aspx [ ^ ].

As I can understand, the Ruler is just a visual element. Make it by sub-classing of System.Windows.Forms.Control, override its OnPaint method for rendering, make rendering depending on the size of a parent control, call System.Windows.Forms.Control.Invalidate of your Ruler instance when resizing, presentation option modification and all other events where the loop of this control should be changed.

See http://msdn.microsoft.com/en-us/library/system.windows.forms.control.aspx[^].
