到网上查了下资料,初步实现了使用WinAPI创建工具栏。
下面是创建一个标准工具栏的函数,(这里所谓标准工具栏是指工具栏按钮图片是WinSDK内置的)
BOOL CreateStandardToolbar(HWND hParent)
{
// 首先需要先调用InitCommonControls函数,否则不能创建工具栏。
InitCommonControls();
HWND hTool;
TBBUTTON tbb[3];
TBADDBITMAP tbab;
HINSTANCE hThisInstance = GetModuleHandle(NULL);
hTool = CreateWindowEx(0, TOOLBARCLASSNAME, NULL, WS_CHILD | WS_VISIBLE|CCS_ADJUSTABLE|WS_CLIPSIBLINGS|WS_CLIPCHILDREN, 0, 0, 0, 0,
hParent,(HMENU)IDC_MAIN_TOOL,hThisInstance, NULL);
if(hTool == NULL)
{
::MessageBox(hParent, "Could not create tool bar.", "Error", MB_OK | MB_ICONERROR);
return FALSE;
}
// 发送 TB_BUTTONSTRUCTSIZE 消息, 出于向后兼容的考虑.
SendMessage(hTool, TB_BUTTONSTRUCTSIZE, (WPARAM)sizeof(TBBUTTON), 0);
tbab.hInst = HINST_COMMCTRL;
tbab.nID = IDB_STD_SMALL_COLOR;
SendMessage(hTool, TB_ADDBITMAP, 0, (LPARAM)&tbab);
ZeroMemory(tbb, sizeof(tbb));
tbb[0].iBitmap = STD_FILENEW;
tbb[0].fsState = TBSTATE_ENABLED;
tbb[0].fsStyle = TBSTYLE_BUTTON;
tbb[0].idCommand = ID_FILE_NEW;
tbb[1].iBitmap = STD_FILEOPEN;
tbb[1].fsState = TBSTATE_ENABLED;
tbb[1].fsStyle = TBSTYLE_BUTTON;
tbb[1].idCommand = ID_FILE_OPEN;
tbb[2].iBitmap = STD_FILESAVE;
tbb[2].fsState = TBSTATE_ENABLED;
tbb[2].fsStyle = TBSTYLE_BUTTON;
tbb[2].idCommand = ID_FILE_SAVEAS;
// 发送添加按钮的消息
SendMessage(hTool, TB_ADDBUTTONS, sizeof(tbb)/sizeof(TBBUTTON), (LPARAM)&tbb);
return TRUE;
}
然后在消息处理函数中调用:
LRESULT CALLBACK WindowProcedure (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
case WM_CREATE:
{
CreateToolbar(hwnd);
break;
}
// 下面是消息响应部分
case WM_COMMAND:
{
switch(LOWORD(wParam))
{
case ID_FILE_NEW:
::MessageBox(hwnd, "新建文件", "提示", MB_OK);
break;
case ID_FILE_OPEN:
::MessageBox(hwnd, "打开文件", "提示", MB_OK);
break;
case ID_FILE_SAVEAS:
::MessageBox(hwnd, "另存文件", "提示", MB_OK);
break;
default:
break;
}
}
}
效果图如下:
但是我们一般是不会SDK内置的资源图片。现在流行界面配置,具体就是我想利用磁盘上位图图片,然后把它作为工具栏按钮图片动态加载到工具栏里去。于是我写了一个函数,实现了这个功能,代码如下:
// 工具栏按钮的命令ID
#define ID_ENTIRE 1028
#define ID_GRID 1029
BOOL CreateCoolToolbar(HWND hParent)
{
InitCommonControls();
// 创建工具栏窗口
HWND hTool;
HINSTANCE hThisInstance = GetModuleHandle(NULL);
hTool = CreateWindowEx(0, TOOLBARCLASSNAME, NULL, WS_CHILD | WS_VISIBLE|CCS_ADJUSTABLE|WS_CLIPSIBLINGS|WS_CLIPCHILDREN, 0, 0, 0, 0,
hParent,(HMENU)IDC_MAIN_TOOL,hThisInstance, NULL);
if(hTool == NULL)
{
::MessageBox(hParent, "Could not create tool bar.", "Error", MB_OK | MB_ICONERROR);
return FALSE;
}
// 发送 TB_BUTTONSTRUCTSIZE 消息, 出于向后兼容的考虑.
SendMessage(hTool, TB_BUTTONSTRUCTSIZE, (WPARAM)sizeof(TBBUTTON), 0);
// 创建图像列表
HIMAGELIST hImgList = ImageList_Create(16,16, ILC_COLOR32|ILC_MASK, 0, 0);
// 为工具栏设置图像列表
::SendMessage(hTool, TB_SETIMAGELIST, 0, (LPARAM)hImgList);
// 打开位图,将其加进图像列表
TCHAR szModulePath[_MAX_PATH];
::GetModuleFileName(NULL,szModulePath,_MAX_PATH);
std::string strBinPath = szModulePath;
int ImgID[2];
// 获取位图文件路径
strBinPath = strBinPath.substr(0,strBinPath.rfind('\\')+1);
std::string strBmpPath = strBinPath + std::string(_T("Toolbar\\entire.bmp"));
HBITMAP hBitmap = NULL;
hBitmap = (HBITMAP)LoadImage(hThisInstance,strBmpPath.c_str(), IMAGE_BITMAP, 0, 0, LR_DEFAULTCOLOR|LR_LOADFROMFILE);
ImgID[0] = ImageList_Add(hImgList,hBitmap,NULL);
strBmpPath = strBinPath + std::string(_T("Toolbar\\Grid.bmp"));
hBitmap = NULL;
hBitmap = (HBITMAP)LoadImage(hThisInstance,strBmpPath.c_str(), IMAGE_BITMAP, 0, 0, LR_DEFAULTCOLOR|LR_LOADFROMFILE);
ImgID[1] = ImageList_Add(hImgList,hBitmap,NULL);
// 初始化工具栏按钮数组
TBBUTTON tbb[2];
tbb[0].iBitmap = ImgID[0];
tbb[0].fsState = TBSTATE_ENABLED;
tbb[0].fsStyle = TBSTYLE_BUTTON;
tbb[0].idCommand = ID_ENTIRE;
tbb[1].iBitmap = ImgID[1];
tbb[1].fsState = TBSTATE_ENABLED;
tbb[1].fsStyle = TBSTYLE_BUTTON;
tbb[1].idCommand = ID_GRID;
// 发送添加工具栏按钮的消息
TBADDBITMAP tbab;
::SendMessage(hTool, TB_ADDBUTTONS, sizeof(tbb)/sizeof(TBBUTTON),(LPARAM)&tbb);
// 设置工具栏按钮大小:16*16
::SendMessage(hTool, TB_SETBUTTONSIZE,NULL,(LPARAM) MAKELONG(16,16));
return TRUE;
}
效果图如下:
