製表鍵子不工作的控制

Question

以下是該窗口包含3套控制我WINAPI程序：

1. ，在窗口中直接組別創建
2. 的控件控制
3. 在第2組

控件當我按Tab鍵，它只在遍歷SET1。 爲什麼我不能通過Tab鍵切換到group1和group2的子控件？

#include <Windows.h> 

LRESULT __stdcall WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam) { 
    switch (message) 
    { 
    case WM_CTLCOLORSTATIC: 
    { 
     HDC hdcStatic = (HDC)wParam; 
     SetTextColor(hdcStatic, RGB(0, 0, 255)); 
     SetBkMode(hdcStatic, TRANSPARENT); 
     return (LRESULT)GetStockObject(NULL_BRUSH); 
    } 
    case WM_DESTROY: 
     PostQuitMessage(0); 
     break; 
    default: 
     return DefWindowProc(hWnd, message, wParam, lParam); 
    } 
    return 0; 
}

託管「組1」和「組2」的兩個子窗口都需要用WS_EX_CONTROLPARENT樣式標記爲「控制父母」。這種風格是指：

本身包含應參加 對話框導航子窗口的窗口。如果執行導航 操作，如處理TAB鍵，方向鍵或鍵盤 助記符

更改您的代碼來創建這些窗口時，這種風格被指定，對話管理 遞歸到該窗口的孩子。如下：

HWND g1 = CreateWindowEx(WS_EX_CONTROLPARENT, L"button", L"Group1", WS_CHILD | WS_VISIBLE | BS_GROUPBOX | WS_TABSTOP | WS_GROUP, 0, 50, 220, 200, hWndMainWindow, (HMENU)++id, NULL, NULL); 
HWND g2 = CreateWindowEx(WS_EX_CONTROLPARENT, L"button", L"Group2", WS_CHILD | WS_VISIBLE | BS_GROUPBOX | WS_TABSTOP | WS_GROUP, 260, 50, 220, 200, hWndMainWindow, (HMENU)++id, NULL, NULL); 

（順便說一句，這似乎是錯誤的使您的Windows組框的孩子他們不需要是 - 你可以放置它們的內部，但讓他們的兄弟姐妹它代替小組。專門設計用於這種方式 - 我不知道我們如何將它作爲兒童與控件一起工作。）

Answer 2

既然你沒有創建一個對話框，你的主窗口應與WS_EX_CONTROLPARENT樣式創建。

確保您只將此樣式放置在主窗口上。孩子的窗戶不應該使用這種風格。
