Window 从最小化 state 恢复后不重新绘制自身

Question

我实际上遇到了 WinAPI 的绘画问题。

我正在创建我的控件，如下所示：

case WM_CREATE:
        g_font = CreateFont(16, 0, 0, 0, FW_DONTCARE, FALSE, FALSE, FALSE, ANSI_CHARSET, CLIP_DEFAULT_PRECIS, CLIP_DEFAULT_PRECIS, DEFAULT_QUALITY, FF_DONTCARE, "MS Dlg Shell");

        g_staticTextToEncrypt = CreateWindowEx(0, "STATIC", "Entrez le texte que vous voulez chiffrer:", WS_CHILD | WS_VISIBLE, 0, 0, 0, 0, window, NULL, GetModuleHandle(NULL), NULL); SendMessage(g_staticTextToEncrypt, WM_SETFONT, (WPARAM)g_font, (LPARAM)TRUE);
        g_staticTextAlphabet = CreateWindowEx(0, "STATIC", "Entrez votre alphabet de substitution:", WS_CHILD | WS_VISIBLE, 0, 0, 0, 0, window, NULL, GetModuleHandle(NULL), NULL); SendMessage(g_staticTextAlphabet, WM_SETFONT, (WPARAM)g_font, (LPARAM)TRUE);
        g_staticEncryptedText = CreateWindowEx(0, "STATIC", "Message chiffré:", WS_CHILD | WS_VISIBLE, 0, 0, 0, 0, window, NULL, GetModuleHandle(NULL), NULL); SendMessage(g_staticEncryptedText, WM_SETFONT, (WPARAM)g_font, (LPARAM)TRUE);

        g_editInputMessage = CreateWindowEx(WS_EX_CLIENTEDGE, "EDIT", "", WS_CHILD | WS_VISIBLE | ES_LEFT | ES_AUTOHSCROLL | ES_UPPERCASE, 0, 0, 0, 0, window, (HMENU)ID_EDIT_INPUT_MESSAGE, NULL, NULL); SendMessage(g_editInputMessage, WM_SETFONT, (WPARAM)g_font, (LPARAM)TRUE);
        g_editInputAlphabet = CreateWindowEx(WS_EX_CLIENTEDGE, "EDIT", "", WS_CHILD | WS_VISIBLE | ES_LEFT | ES_AUTOHSCROLL | ES_UPPERCASE, 0, 0, 0, 0, window, (HMENU)ID_EDIT_INPUT_ALPHABET, NULL, NULL); SendMessage(g_editInputAlphabet, WM_SETFONT, (WPARAM)g_font, (LPARAM)TRUE);
        g_editOutputEncryptedText = CreateWindowEx(WS_EX_CLIENTEDGE, "EDIT", "", WS_CHILD | WS_VISIBLE | ES_CENTER | ES_AUTOHSCROLL | ES_READONLY, 0, 0, 0, 0, window, (HMENU)ID_EDIT_OUTPUT_ENCRYPTED_TEXT, NULL, NULL); SendMessage(g_editOutputEncryptedText, WM_SETFONT, (WPARAM)g_font, (LPARAM)TRUE);

        g_buttonCopyEncryptedText = CreateWindowEx(0, "BUTTON", "Copier", WS_CHILD | WS_VISIBLE | BS_CENTER, 0, 0, 0, 0, window, ID_BUTTON_COPY_ENCRYPTED_TEXT, NULL, NULL); SendMessage(g_buttonCopyEncryptedText, WM_SETFONT, (WPARAM)g_font, (LPARAM)TRUE);

        break;

因此，即使用户调整了窗口大小，我也可以使它们居中，我正在处理 WM_PAINT 消息：

case WM_PAINT:
        BeginPaint(window, &ps);

        hdc = GetDC(g_staticTextToEncrypt);
        SelectObject(hdc, g_font);
        GetTextMetrics(hdc, &tm);
        ReleaseDC(g_staticTextToEncrypt, hdc);

        GetWindowRect(window, &windowSize);
        setNewControlsPos(&windowSize, &tm);

        EndPaint(window, &ps);
        break;

setNewControlsPos只是在执行SetWindowPos(g_staticTextToEncrypt, HWND_BOTTOM, ..., ..., ..., ..., SWP_SHOWWINDOW); 对于在 WM_CREATE 中创建的每个控件

问题是当我最小化 window 并恢复它时，window 是白色的，每个控件都在野外消失了。 我认为问题出在我没有重新绘制 WM_PAINT 中的控件，而只是重新定位它们，但我不知道如何正确地重新绘制控件。

我尝试使用RedrawWindow(..., NULL, NULL, RDW_ERASE | RDW_INVALIDATE); 或InvalidateRect(..., NULL, FALSE); 在每个控件上，但它没有效果。
