TB_ADDBUTTONS message

Adds one or more buttons to a toolbar.

Parameters

wParam

Number of buttons to add.

lParam

Pointer to an array of TBBUTTON structures that contain information about the buttons to add. There must be the same number of elements in the array as buttons specified by wParam.

Return value

Returns TRUE if successful, or FALSE otherwise.

Remarks

If the toolbar was created using the CreateWindowEx function, you must send the TB_BUTTONSTRUCTSIZE message to the toolbar before sending TB_ADDBUTTONS.

See TB_SETIMAGELIST for a discussion of how to assign bitmaps to toolbar buttons from one or more image lists.

Examples

The following example code adds three buttons to a toolbar, using the standard system bitmap for view buttons. The TB_ADDBITMAP message returns the index of the first button image within the image list. Individual images are identified by their offsets from that value.

TBADDBITMAP tbAddBitmap;
tbAddBitmap.hInst = HINST_COMMCTRL;
tbAddBitmap.nID = IDB_VIEW_SMALL_COLOR;

// There are 12 items in IDB_VIEW_SMALL_COLOR.  However, because this is a standard
// system-defined bitmap, the wParam (nButtons) is ignored.
//
// hWndToolbar is the handle of the toolbar window.
//
// Do not forget to send TB_BUTTONSTRUCTSIZE if the toolbar was created
// by using CreateWindowEx.
//
int stdidx = SendMessage(hWndToolbar, TB_ADDBITMAP, 0, (LPARAM)&tbAddBitmap);

// Define the buttons. 
// IDM_SETLARGEICONVIEW and so on are application-defined command IDs.

const int numButtons = 3;
TBBUTTON tbButtonsAdd[numButtons] = 
{
    {stdidx + VIEW_LARGEICONS, IDM_SETLARGEICONVIEW, TBSTATE_ENABLED, BTNS_BUTTON},
    {stdidx + VIEW_SMALLICONS, IDM_SETSMALLICONVIEW, TBSTATE_ENABLED, BTNS_BUTTON},
    {stdidx + VIEW_DETAILS, IDM_SETDETAILSVIEW, TBSTATE_ENABLED, BTNS_BUTTON}
}; 

// Add the view buttons.
SendMessage(hWndToolbar, TB_ADDBUTTONS, numButtons, (LPARAM)tbButtonsAdd);
