我创建了顶层窗口,但由于未知原因,我的 WNDPROC 没有收到WM_LBUTTONDOWN/WM_LBUTTONUP或WM_MOUSEMOVE消息。
有什么建议么?
相关代码:
WNDCLASSEX wc = {0};
Wc.cbSize = 48;
Wc.cbWndExtra = 80;
Wc.hCursor = LoadCursorW(g_hInstance, MAKEINTRESOURCEW(1002));
Wc.style = CS_GLOBALCLASS | CS_DBLCLKS;
Wc.lpszClassName = Ici[dItemIndex].sInit;
Wc.lpfnWndProc = Ici[dItemIndex].wInit;
RegisterClassExW(&Wc);
g_hRuler1 = CreateWindowExW(WS_EX_TOOLWINDOW,
RULER_CONTROL,
L"",
WS_POPUP|WS_VISIBLE|0x1,
100 ,100, 40, RECTHEIGHT(g_rScreen),
NULL, NULL, hInst, NULL);
LRESULT WINAPI Ruler_Window(HWND hWindow, UINT uWindow, WPARAM wParam, LPARAM lParam)
{
if (uWindow == WM_GETMINMAXINFO)
{
goto DODEFAULT;
}
if (uWindow == WM_NCCREATE)
{
g_pGRI = RULER_ALLOCATE();
RULER_SET_POINTER(hWindow, (LONG_PTR)g_pGRI);
return 1L;
}
g_pGRI = RULER_GET_POINTER(hWindow);
g_pGRI->hWindow = hWindow;
switch(uWindow)
{
case WM_CREATE:
{
return Ruler_OnCreate(wParam, lParam);
}
case WM_PAINT:
{
return Ruler_OnPaint(wParam, lParam);
}
case WM_MOUSEMOVE:
{
return Ruler_OnMouseMove(wParam, lParam);
}
case WM_DESTROY:
{
return Ruler_OnDestroy(wParam, lParam);
}
case WM_SETCURSOR:
{
return Ruler_OnSetCursor(wParam, lParam);
}
case WM_LBUTTONDOWN:
{
return Ruler_OnLeftButtonDown(wParam, lParam);
}
case WM_LBUTTONUP:
{
return Ruler_OnLeftButtonUp(wParam, lParam);
}
case GM_SETINDICATORS:
{
return Ruler_OnSetIndicators(wParam, lParam);
}
DODEFAULT:
return DefWindowProcW(hWindow, uWindow, wParam, lParam);
}
}
