确定表单的打开位置. [英] Determining opening location of a form.

问题描述

我的表单上有一个按钮.当我单击它时，我希望在按钮所在的位置完全打开一个表单.如何实现呢?

I have a button on my form. When I click it, I want a form to be opened exactly on the location where the button is. How to achieve this? Thanks.

推荐答案

在表单属性中，将StartPosition设置为Manual.
然后:

In the form properties, set the StartPosition to Manual.
Then:

myForm f = new myForm();
f.Location = Cursor.Position;
f.Show();

将其设置为当前鼠标位置.
或:

This sets it to the current mouse position.
Or:

myForm f = new myForm();
f.Location = PointToScreen(myButton.Location);
f.Show();

将其设置为按钮位置-按钮将被表单覆盖.

This sets it to the button location - the button will be covered by the form.

您可以通过以下两种方式之一进行操作:

0)处理鼠标左键按下事件，然后您可以在单击时检索鼠标位置.然后，您可以在该光标位置打开一个表单.

1)处理按钮单击事件，并将for放置在要单击的按钮的左上角.

You can do it one of two ways:

0) Handle the Left Mouse button Down event, and you can then retrieve mouse position at the time of the click. Then, you can open a form at that cursor position.

1) Handle the button click event and position the for at the top/left corner of the button being clicked.
