推荐答案

为什么不将用户绘制的按钮与按钮上的图标设计一起使用?那应该可以让您访问所有正常的按钮交互.

Why not use a user drawn button with the icon design on the button? That should give you access to all normal button interaction.

这意味着没有解决方案可以将鼠标单击控件赋予在视图类中绘制的矩形或图标.对话为主.因此，在OnDraw()中，我先绘制一个位图，然后在该位图上绘制一个矩形.然后我在该矩形上附加了一个图标.现在我想要的是，只要有人单击该图标(矩形区域)，就应该打开一个文件.

that means no solution to give mouse click control to a rectangle or an icon drawn in a view class.. I am not supposed to use dialogue based. So in OnDraw() i draw a bitmap then a rectangle over bitmap. then i attached an Icon to that rectangle. Now what i want is when ever some one clicks on the icon(rectangle area), a file should be opened..

您可以处理WM_LBUTTONDOWN.
它会为您提供最后一次左键单击的坐标.
只需检查它们是否在矩形中即可.

You can handle WM_LBUTTONDOWN.
it gives you the coordinate of the last left-button click.
Just check if they are into the rectangle.
