如何使矩形可点击，C＃

Question

The code can generate rectangles (Rectangle rectangle) at runtime. The position of rectangles may change according to users' choices.

I want to add code in the method where it creates rectangles to make the rectangles clickable. And after user clicking the rectangle, there will be a new window to show content just like text.

Answer 1

You can use Contains method of the Rectangle object.

private Rectangle _myRectangle;
private void Form1_MouseDown(object sender, MouseEventArgs e)
{
    if (this._myRectangle.Contains(e.Location))
    {

    }
}

Answer 2

Create a label control with the border property and transaparent background(so that it will look as rectangle) and add click event handler for each label you add. It will be good if you create your own Rectangle control by deriving from Label class or you can create your own control(Many other solutions).

Answer 3

我将考虑处理窗口本身（或任何“背景”控件是）上的click事件，获取其坐标，并将其与矩形的已知位置/大小进行比较。
