Question

我正在尝试使用自己的自定义图像在win32 winapi程序中创建工具栏。这就是我所拥有的（在我的WM_CREATE情况下）：

#define IDT_MAIN_TOOL     101
TBBUTTON tbb[ 1 ];
TBADDBITMAP tbab;

HWND hToolbar = CreateWindowEx( 0, TOOLBARCLASSNAME, NULL, WS_CHILD | WS_VISIBLE | TBSTYLE_FLAT, 0, 0, 0, 0, hwnd, ( HMENU )IDT_MAIN_TOL, NULL, NULL );

SendMessage( hToolbar, TB_BUTTONSTRUCTSIZE, ( WPARAM )sizeof( TBBUTTON ), 0 );

tbab.hInst = HINST_COMMCTRL;
tbab.nID = IDB_HIST_LARGE_COLOR;
SendMessage( hToolbar, TB_ADDBITMAP, 0, ( LPARAM )&tbab );

ZeroMemory( tbb, sizeof( tbb ) );

tbb[ 0 ].iBitmap = HIST_BACK;
// I've also tried tbb[ 0 ].iBitmap = LoadIcon( NULL, "browse_back.ico" );
// However, iBitmap must be an integer and can't figure out how to use my 'browse_back.ico' image
tbb[ 0 ].fsState = TBSTATE_ENABLED;

SendMessage( hToolbar, TB_ADDBUTTONS, sizeof( tbb ) / sizeof( TBBUTTON ), ( LPARAM )&tbb );

我想使用自己的图标图片：'browse_back.ico'作为该工具栏按钮的图像。这是如何完成的？不确定这是否有必要，但我使用的是Microsoft Visual C ++ 2010 Express。

Answer 1

Read the documentation：

iBitmap   键入：int

按钮图像的从零开始的索引。将此成员设置为I_IMAGECALLBACK，工具栏将发送TBN_GETDISPINFO通知代码以在需要时检索图像索引。

版本5.81。将此成员设置为I_IMAGENONE以指示该按钮没有图像。按钮布局不包含位图的任何空间，只包含文本。

如果按钮是分隔符，也就是说，如果fsStyle设置为BTNS_SEP，则iBitmap确定分隔符的宽度（以像素为单位）。 有关从图像列表中选择按钮图像的信息，请参阅TB_SETIMAGELIST消息。

因此，您需要使用ImageList_Create()创建图像列表，使用ImageList_Add()或ImageList_ReplaceIcon()将ICO图像添加到其中，使用TB_SETIMAGELIST将其与工具栏相关联，然后你可以将tbb[0].iBitmap设置为图像列表中的ICO索引。

我知道有两种方法。一个正在使用TBADDBITMAP，另一个正在使用HIMAGELIST。在此示例中，我使用TBADDBITMAP，但我个人更喜欢HIMAGELIST。

IDB_DOCUMENT         BITMAP   "document.bmp"
IDB_DRUGS            BITMAP   "drugs.bmp"
