不规则形状的按钮 [英] Irregular shaped buttons

问题描述

大家好，

我正在寻找一种方法来检查我的光标当前是否在特定的绘图上，以便可以突出显示它.

假设这可能是形状:

Hello everyone,

I am looking for a method to check if my cursor is currently over a specific draw so it can be highlighted.

Let''s say this is may shape:

  ___________
 /          /
/__________/

如您所见，有一些备用空间(按钮通常是直框).
如何排除剩余空间?

大家知道，我使用GraphicsPath绘制了线条.

As you can obviously see, there''s a bit of spare space (buttons are usually straight boxes).
How can I exclude the spare space?

Just so you know, I draw the lines using a GraphicsPath.

推荐答案

检查光标坐标(作为Point类型)是否在该区域内. >

Check if the cursors coordinates (as a Point type) lie within in that region.

Pont point = ...; //Set mouse coordinates here.
GraphicsPath path = ...; // Create your path here.
if(path.IsVisible(point)) ... // Check if mouse coordinates are within path

问候，

如Manfred所说，将您的Path转换为Region并使用 ^ ]方法.

As Manfred has said, convert your Path to a Region and use the Region.IsVisible(Point)[^] method.

所有其他答案都不完全正确.它们仅有助于定义可见区域或以特殊方式处理鼠标事件.最终的解决方案是:

在按钮HWND上使用Windows API SetWindowRgn.它将在各个方面将按钮Windows塑造成一个区域，不仅是视觉上的，而且仅当鼠标事件发生在指定区域内时，鼠标事件才会被自动路由.请参阅 http://msdn.microsoft.com/en-us/library/dd145102(v = vs.85).aspx [

All other answers are not quite correct. They only help to define visible area or process mouse events in a special way. The ultimate solution is this:

Use Windows API SetWindowRgn on a button HWND. It will shape a buttons Windows to a region in all aspects, not just visual, but the mouse event will be automatically routed only if they happen within the specified region. See http://msdn.microsoft.com/en-us/library/dd145102(v=vs.85).aspx[^].
