在WPF中在运行时将鼠标单击与行连接 [英] Joining Mouse clicks with a line at runtime in WPF

问题描述

大家好，

任何人都可以给我一个想法，如何在运行时将鼠标单击与一行连接起来.
我通过单击按钮在窗口上有一个Joinbutton，鼠标单击应该加入.
例如 在窗口上，如果我单击两次并单击Joinbutton，则两个mouseclick位置应用一条线连接.
如果我在窗口上单击三下并单击Joinbutton，则三个mouseclick位置应连接并形成一个三角形，类似地，对于四单击，鼠标单击位置应连接并形成一个矩形.

请提出您的建议以解决此问题.

谢谢，

Hello all,

Could any one give me idea how to join mouse clicks with a line at runtime.
i have a Joinbutton on window by clicking button the mouse clicks should join.
for eg.
on window, if i click two times and click on Joinbutton the two mouseclick positions should join with a line.
if i click three times on window and click on Joinbutton the three mouseclick positions should join and form a triangle, similarly for four click , the mouse click positions should join and form a rectangle.

Plz give your suggestions to resolve this.

Thanks,

Enough to get you going I think.

在鼠标按下时，将位置添加到列表(List< Point>)应该可以解决问题.按下按钮后，从列表中读取所有点并创建一个新的多边形(除非只有两个点，在这种情况下为一条线)并将其添加到父级.

On mouse down, add the location to a list (List<Point>) should do the trick. On pressing the button, read all the points out of the list and make a new polygon (unless there are only two points, in which case a line) and add it to the parent.
