Then we will add a toolbar to our application.
It will be a simple toolbar with buttons, with text and bitmaps.
First we must create the window itself
ToolBarWindow = CreateWindowEx(0, TOOLBARCLASSNAME, 0, WS_CHILD| WS_BORDER, 0, 0, 0, 0, ParentWindow, (HMENU )ToolBarId, InstanceHandle, 0);No surprise here, except the wnd-class name, TOOLBARCLASSNAME, which is the name of a predefined wnd-class for toolbars.
ToolBarId is the ID for the toolbar, it's defined the same way as StatusBarId, in the same enumeration.
The next to do is to TB_BUTTONSTRUCTSIZE message to the window, I'm not sure why this is needed, but the documentation say we have to:
SendMessage(ToolBarWindow, TB_BUTTONSTRUCTSIZE, (WPARAM )sizeof(TBBUTTON), 0);Next we have to tell the toolbar which bitmap to use, in this simple case we will use a standard set, it has 14 images to choose from, it fits nicely to this demo purpose.
TBADDBITMAP TBaddBitmap; TBaddBitmap.hInst = HINST_COMMCTRL; TBaddBitmap.nID = IDB_STD_SMALL_COLOR; SendMessage(ToolBarWindow, TB_ADDBITMAP, (WPARAM )NumButton, (LPARAM )&TBaddBitmap);Notice that we use HINST_COMMCTRL as instance, as the bitmap is stored in the comctrl dll.
NumButton the number of buttons we will have on the toolbar, its defined as:
const int NumButton = 3;Next we have to specify what text to show on the buttons and which bitmap to use:
TBBUTTON ButtonInfo[NumButton]; memset(ButtonInfo, 0, sizeof(ButtonInfo)); int idx; idx = SendMessage(ToolBarWindow, TB_ADDSTRING, 0, (LPARAM )"Open"); ButtonInfo.iString = idx; ButtonInfo.iBitmap = STD_FILEOPEN; ButtonInfo.idCommand = FileOpenCmd; ButtonInfo.fsState = TBSTATE_ENABLED; ButtonInfo.fsStyle = TBSTYLE_BUTTON;This has to be repeated for each button.
Then we sends this information to the toolbar:
SendMessage(ToolBarWindow, TB_ADDBUTTONS, NumButton, (LPARAM)&ButtonInfo);And at the end we show the toolbar:
ShowWindow(ToolBarWindow, SW_SHOW);As for the statusbar, we must tell the toolbar to resize when the mainwindow is resized, so we add this line to the WM_SIZE handling:
SendMessage(ToolBarWindow, msg, wParam, lParam);The complete code for the application can be found here
