在屏幕上找到坐标点? [英] Find Coordinates for point on screen?

问题描述

问题是我以表格形式显示了一些图形，例如矩形，并且当点超过thees字段时我想捕获.因此，我尝试找到这些矩形的corrrdinates，但由于坐标是形式，因此与鼠标位置不匹配.

The thing is I have some graphics shown in a form, rectangle for example, and I want to capture when the point gets over thees fields. So I Thoght I try to find the corrrdinates for thees rectangles, but as thay are the coords in the form it dose not match the ones with the mouse location.

所以我想知道是否有一种方法可以找到Point在屏幕上而不是在窗体或控制器中在屏幕上的坐标?

So I wonder is there a way to find what coord on the screen a Point has on the screen and not in the form or controller?

推荐答案

每个控件都有用于转换的PointToFoo方法.请注意，您应该从所需位置的对象的父对象处调用它:

Each control hs PointToFoo methods for conversion. Note that you should call this from the parent of the object who's location you want:

Point scrPos = this.PointToScreen(panel1.Location);

或者，您可以使用以下方法获取面板的屏幕坐标:

Alternatively, you can get the panel's screen coordinates with:

Point scrPos = panel1.PointToScreen(new Point(0,0));

请注意，由于面板的边框大小，以上两个示例可能会得出不同的结果.

Note that the above two examples could gve different result due to the border-size of the panel.
