windows工具栏制作

为了以后查找方便,列几个关键字吧.

关键字: TB_SETIMAGELIST 工具栏风格 ImageList

 

工具栏制作不是大问题,但理解API层仍有意义.OK,开始吧.

 

创建工具栏可以用下面方法:

You can use two functions to create a toolbar—CreateToolbarEx or CreateWindowEx. The CreateToolbarEx function creates a toolbar and adds an initial set of buttons to it. You can also use CreateWindowEx, specifying the TOOLBARCLASSNAME window class to create a toolbar that initially contains no buttons. The TOOLBARCLASSNAME window class is registered when the common control dynamic-link library (DLL) is loaded. To ensure that this DLL is loaded, use the InitCommonControlsEx function first. If you create an empty toolbar, you add buttons to it by using the TB_ADDBUTTONS or TB_INSERTBUTTON message. If you retrieve the size of the toolbar, you must send the TB_AUTOSIZE message after all the items and strings have been inserted into the control to cause the toolbar to recalculate its size based on its content.

简单工具栏上面一段介绍可以给出思路了.况且示例最多就是这种.
但象freedownload下载软件的工具栏是真彩位图,又用了多个位图,上面的简单法子就不行了.

如果工具栏用到多个位图,就需要用到IMAGELIST.大概步骤如下:
1 从位图资源创建 IMAGELIST,会返回一相HIMAGELIST 句柄.
2 给工具栏通知IMAGELIST,相关消息TB_SETIMAGELIST .
3 给每个按钮的iBitmap赋值.

上面3中赋值有点问题:
For each button, set the iBitmap member of the button's TBBUTTON structure to MAKELONG(iIndex, iImageID). The iImageID value is the ID of the appropriate image list that was defined in step two. The iIndex value is the index of the particular image within that list.
嘿嘿,人家说清了,偶再理解一下.
以前是直接给一个索引iIndex就好了,但现在是多个位图,为了指明是哪个位图,这里又多了个位图本身的索引iImageID.所以用MAKELONG(iIndex, iImageID). 多说一句:iImageID是我们自定义的.像数组一样,从0开始吧.

还有个问题:
freedownload的工具栏使用了 和 
两种风格.单独理解是前者使工具栏窗口和按钮都透明,而后者是工具栏窗口透明而按钮不透明.为什么使用了两者?不明白到底按钮透不透明呢?最好方法是试一下.但偶始终没同时用后者.
这两种风格都有一个注意事项: 不要和WS_VISIBLE一块使用.否则背景不是系统的,而是程序运行时窗口所在位置上的别的窗口中的内容.这不是我们想要的.去除WS_VISIBLE,需要显示时ShowWindow即可.

同样工具栏有大量的消息用SendMessage.用户和系统都使用这些消息,包括添加按钮,文本,位图.

下面四种风格用于工具栏时,可取消一些默认行为,有空再来细说.如果嫌系统的行为不好,想自己控制,不妨试试.
CCS_NODIVIDER|CCS_NORESIZE|CCS_NOMOVEY|CCS_NOPARENTALIGN

偶有一段WTL中的代码,可能性对理解有用:

DWORD dwTBStyle=WS_CHILDWINDOW|WS_CLIPSIBLINGS|CCS_NODIVIDER\
   |CCS_NORESIZE|CCS_NOMOVEY|CCS_NOPARENTALIGN|TBSTYLE_FLAT;//|TBSTYLE_TRANSPARENT;
   DWORD dwTBExStyle=WS_EX_LEFT|WS_EX_LTRREADING|WS_EX_RIGHTSCROLLBAR;
   HWND hWndToolBar=m_toolbar.Create(m_hWnd,CRect(0,0,260,36),NULL,dwTBStyle,dwTBExStyle);
   m_toolbar.SetButtonStructSize();
   m_imageList.CreateFromImage(IDB_BITMAP1,32,6,CLR_DEFAULT,IMAGE_BITMAP,LR_LOADTRANSPARENT|LR_CREATEDIBSECTION);
   m_toolbar.SetHotImageList(m_imageList);
   m_imageList.Detach();
   m_imageList.CreateFromImage(IDB_BITMAP3,32,6,CLR_DEFAULT,IMAGE_BITMAP,LR_LOADTRANSPARENT|LR_CREATEDIBSECTION);
   m_toolbar.SetImageList(m_imageList);
   m_imageList.Detach();
   m_toolbar.SetButtonSize(32,32);
   
   TBBUTTON tbb[6];
   ZeroMemory(tbb,sizeof(tbb));
   tbb[0].iBitmap =0;
   tbb[0].fsState =TBSTATE_ENABLED;
   tbb[0].fsStyle =TBSTYLE_BUTTON;
   tbb[0].idCommand=ID_STOPTASK;

   tbb[1].iBitmap = 1;
   tbb[1].fsState = TBSTATE_ENABLED;
   tbb[1].fsStyle = TBSTYLE_BUTTON;
   tbb[1].idCommand = ID_STOPTASK;

   tbb[2].iBitmap = 2;
   tbb[2].fsState = TBSTATE_ENABLED;
   tbb[2].fsStyle = TBSTYLE_BUTTON;
   tbb[2].idCommand = ID_STOPTASK;

   tbb[3].iBitmap = 3;
   tbb[3].fsState = TBSTATE_ENABLED;
   tbb[3].fsStyle = TBSTYLE_BUTTON;
   tbb[3].idCommand = ID_STOPTASK;

   tbb[4].iBitmap = 4;
   tbb[4].fsState = TBSTATE_ENABLED;
   tbb[4].fsStyle = TBSTYLE_BUTTON;
   tbb[4].idCommand = ID_STOPTASK;

   tbb[5].iBitmap = 5;
   tbb[5].fsState = TBSTATE_ENABLED;
   tbb[5].fsStyle = TBSTYLE_BUTTON;
   tbb[5].idCommand = ID_STOPTASK;
   
   m_toolbar.AddButtons(6,tbb);
  
  ::ShowWindow(m_toolbar,SW_NORMAL);
  m_hWndToolBar=m_toolbar;
  m_imageList.Destroy();

 

错误之处劳烦您费费手指出,谢谢.
