推荐答案

计算要连接的两个控件的大小和位置，找出控件的哪一侧应该连接，计算中心的位置对于每个控件，并在这两个点之间绘制线。

Calculate the size and position of both controls you want to connect, find out which side of the controls should be connected, calculate the position of the centre of that side for each control and draw the line between those 2 points.
