使用Win32 API添加工具欄對話框

Question

我有一個對話框，在其上用控件添加資源編輯器。但我試圖在WM_INITGDIALOG消息中動態創建一個工具欄，但工具欄不可見。還有其他事情要做嗎？（我不這麼認爲，但是......）。如果這是不可能的，如何在資源編輯器中添加一個工具欄。

正如你猜我使用VS 2008

CreateButtons(HWND hwnd) 
{ 
    HIMAGELIST m_hTBImageList; 
    HIMAGELIST m_hTBHottrack; 



    HWND hwndSysButtonTB = CreateWindowEx(0, 
     TOOLBARCLASSNAME, 
     _T(""), 
     WS_CHILD | WS_VISIBLE | TBSTYLE_FLAT | TBSTYLE_TOOLTIPS | CCS_NORESIZE | CCS_NOPARENTALIGN, 
     toolbarRect.left, toolbarRect.top, toolbarRect.right-toolbarRect.left, toolbarRect.bottom-toolbarRect.top, 
     hwnd, 
     (HMENU)IDR_TOOLBAR, 
     (HINSTANCE)hAppInstance, 
     NULL); 

    m_hTBImageList = ImageList_LoadImage((HINSTANCE)hAppInstance, 
     MAKEINTRESOURCE(IDB_BITMAP_ICONS), toolbarButtonSize.cx, 1, 
     0, IMAGE_BITMAP, LR_CREATEDIBSECTION|LR_SHARED); 
    m_hTBHottrack = ImageList_LoadImage((HINSTANCE)hAppInstance, 
     MAKEINTRESOURCE(IDB_MOUSEOVER), toolbarButtonSize.cx, 1, 
     0, IMAGE_BITMAP, LR_CREATEDIBSECTION|LR_SHARED); 

    SendMessage(hwndSysButtonTB, (UINT) TB_SETIMAGELIST, 0, (LPARAM)m_hTBImageList); 
    SendMessage(hwndSysButtonTB, (UINT) TB_SETHOTIMAGELIST, 0, (LPARAM)m_hTBHottrack); 
    SendMessage(hwndSysButtonTB, (UINT) TB_BUTTONSTRUCTSIZE, (WPARAM)sizeof(TBBUTTON), 0); 

    // win2k: set color of hot tracking frame 
    COLORSCHEME scheme; 
    scheme.dwSize = sizeof(scheme); 
    scheme.clrBtnHighlight = RGB(175,175,175); 
    scheme.clrBtnShadow = RGB(175,175,175); 
    SendMessage(hwndSysButtonTB, (UINT) TB_SETCOLORSCHEME, 0, (LPARAM)&scheme); 

    TBBUTTON ButtonEnd =   {0,ID_BUTTON_END,TBSTATE_ENABLED,TBSTYLE_BUTTON}; 
    TBBUTTON ButtonRefresh =  {1,ID_BUTTON_REFRESH,TBSTATE_ENABLED,TBSTYLE_BUTTON}; 
    TBBUTTON ButtonOptions =  {2,ID_BUTTON_PROPERTIES,TBSTATE_ENABLED,TBSTYLE_BUTTON}; 



    SendMessage(hwndSysButtonTB, (UINT) TB_ADDBUTTONS, 1, (LPARAM)&ButtonEnd); 
    SendMessage(hwndSysButtonTB, (UINT) TB_ADDBUTTONS, 1, (LPARAM)&ButtonRefresh); 
    SendMessage(hwndSysButtonTB, (UINT) TB_ADDBUTTONS, 1, (LPARAM)&ButtonOptions); 

} 

Answer 1

你必須調用

SendMessage(hwndSysButtonTB, TB_AUTOSIZE, 0, 0); 
ShowWindow(hwndSysButtonTB , SW_SHOW); 

在你的函數結束。

我想你應該使用TBBUTTON數組而不是三個單獨的變量。然後你可以一次添加它們全部與

SendMessage(hwndSysButtonTB, (UINT) TB_ADDBUTTONS, 3, (LPARAM)&ButtonArray);
