窗口框架不在Windows 10上重绘 [英] Window frame not redraw on Windows 10

问题描述

在我的SW系统中，我实施了一个 浮动工具栏，它在Windows 7上运行正常，但在更改为Windows  10之后，存在一些问题。当在工具栏上移动另一个窗口然后移出时，右框架和底框架不会重新绘制。

窗口类继承自CWnd，请参阅下面的代码。如果删除WS_EX_TOOLWINDOW样式，则工具栏显示正确。

 BOOL CTGraphics :: Create（LPCTSTR lpszWindowName，const RECT& rect，CWnd * pParentWnd）
 {
 DWORD dwStyle = WS_POPUP | WS_CLIPSIBLINGS | WS_SYSMENU | WS_CAPTION; 
 DWORD dwExStyle = WS_EX_TOOLWINDOW | WS_EX_WINDOWEDGE | WS_EX_LEFT | WS_EX_LTRREADING; 
 
 int nWidth，nHeight; 
 POINT tpoint; 
 nWidth = 50; 
 nHeight = 100; 
 tpoint.x = 0; 
 tpoint.y = 0; 
 
 BOOL result = CreateEx（dwExStyle，AfxRegisterWndClass（CS_HREDRAW | CS_VREDRAW），lpszWindowName，dwStyle，tpoint.x，tpoint.y，nWidth，nHeight，pParentWnd-> GetSafeHwnd（），（HMENU）0 ）; 
 
返回结果; 
}

In my SW system, I've implemented a floating toolbar, it works fine on Windows 7, but after change to Windows 10, there's some problem. When move another window over the toolbar then move out, the right and bottom frame are not redrawn.

The window class is inherited from CWnd, see code bellow. If remove WS_EX_TOOLWINDOW style, the toolbar show correctly.

BOOL CTGraphics::Create(LPCTSTR lpszWindowName, const RECT& rect,CWnd* pParentWnd)
{
    DWORD dwStyle   = WS_POPUP|WS_CLIPSIBLINGS|WS_SYSMENU|WS_CAPTION;
    DWORD dwExStyle = WS_EX_TOOLWINDOW|WS_EX_WINDOWEDGE|WS_EX_LEFT|WS_EX_LTRREADING;

    int nWidth,nHeight;
    POINT tpoint;
    nWidth  = 50;
    nHeight = 100;
    tpoint.x = 0 ;
    tpoint.y = 0;

    BOOL result = CreateEx(dwExStyle, AfxRegisterWndClass(CS_HREDRAW | CS_VREDRAW), lpszWindowName, dwStyle, tpoint.x, tpoint.y, nWidth, nHeight, pParentWnd->GetSafeHwnd(), (HMENU)0);

    return result;
}

Hi,

thanks for posting here.

Please provide more information about your project and CTGraphics class. Or it could be better if you could share us a demo project to reproduce your issue.
