鼠标位置检测

[cokeliu]

在对话框工程的MouseMove中我想检测鼠标光标是否在一个CStatic矩形框内.
GetDlgItem(IDC_TFT)->GetWindowRect(&MyProject.MyLayout.TFT_Mouse);
ScreenToClient(MyProject.MyLayout.TFT_Mouse);

void CTFT_ToolDlg::OnLButtonDown(UINT nFlags, CPoint point)
{
if(MyProject.MyLayout.TFT_Mouse.PtInRect(point))
{
.........
}
}
测试时候发现位置不是很准，请问是否需要做一个坐标转换?

感觉逻辑上没有啥问题啊

可以全部变换到屏幕坐标判断，因为OnLButtonDown的坐标位置好像是相对于窗口左上角，不是客户区的左上角，相差了几个像素。

GetWinowRect 想对于 屏幕 Points to a CRect object or a RECT structure that will receive the screen coordinates of the upper-left and lower-right corners. OnLButtonDown 相对于 控件. Specifies the x- and y-coordinate of the cursor. These coordinates are always relative to the upper-left corner of the window.

实际测试时候比较鼠标明明放在CStatic方框内了，但鼠标坐标显示在方框外，应该是鼠标坐标显示比实际小些，怎么转换到对话框的控件坐标系统做比较呢.
