Toolbar Images

I have created a toolbar as follows:

Code:

TBADDBITMAP Bitmap;
	TBBUTTON Button[14];

	hTool = CreateWindowEx(0, TOOLBARCLASSNAME, "",
						WS_CHILD | WS_VISIBLE | TBSTYLE_FLAT | TBSTYLE_TOOLTIPS,
						0, 0, 0, 0,	hwnd, NULL,	ghInstance,	NULL);

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

	Bitmap.hInst = HINST_COMMCTRL;
	Bitmap.nID = IDB_STD_SMALL_COLOR;

	SendMessage(hTool, TB_ADDBITMAP, 0, (LPARAM) &Bitmap);

	ZeroMemory(Button, sizeof(Button));

	Button[0].iBitmap   = STD_FILENEW;
	Button[0].fsState   = TBSTATE_ENABLED;
	Button[0].fsStyle   = TBSTYLE_BUTTON;
	Button[0].idCommand = MENU_FILE_NEW;

	Button[1].iBitmap   = STD_FILEOPEN;
	Button[1].fsState   = TBSTATE_ENABLED;
	Button[1].fsStyle   = TBSTYLE_BUTTON;
	Button[1].idCommand = MENU_FILE_OPEN;

	Button[2].iBitmap   = STD_FILESAVE;
	Button[2].fsState   = TBSTATE_ENABLED;
	Button[2].fsStyle   = TBSTYLE_BUTTON;
	Button[2].idCommand = MENU_FILE_SAVE;

	Button[3].iBitmap   = STD_PRINT;
	Button[3].fsState   = TBSTATE_ENABLED;
	Button[3].fsStyle   = TBSTYLE_BUTTON;
	Button[3].idCommand = MENU_FILE_PRINT;

	Button[4].fsStyle   = TBSTYLE_SEP;

	Button[5].iBitmap   = STD_CUT;
	Button[5].fsState   = TBSTATE_ENABLED;
	Button[5].fsStyle   = TBSTYLE_BUTTON;
	Button[5].idCommand = MENU_EDIT_CUT;

	Button[6].iBitmap   = STD_COPY;
	Button[6].fsState   = TBSTATE_ENABLED;
	Button[6].fsStyle   = TBSTYLE_BUTTON;
	Button[6].idCommand = MENU_EDIT_COPY;

	Button[7].iBitmap   = STD_PASTE;
	Button[7].fsState   = TBSTATE_ENABLED;
	Button[7].fsStyle   = TBSTYLE_BUTTON;
	Button[7].idCommand = MENU_EDIT_PASTE;

	Button[8].fsStyle   = TBSTYLE_SEP;

	Button[9].iBitmap   = STD_UNDO;
	Button[9].fsState   = TBSTATE_ENABLED;
	Button[9].fsStyle   = TBSTYLE_BUTTON;
	Button[9].idCommand = MENU_EDIT_UNDO;

	Button[10].iBitmap   = STD_FIND;
	Button[10].fsState   = TBSTATE_ENABLED;
	Button[10].fsStyle   = TBSTYLE_BUTTON;
	Button[10].idCommand = MENU_SEARCH_FIND;

	Button[11].iBitmap   = STD_REPLACE;
	Button[11].fsState   = TBSTATE_ENABLED;
	Button[11].fsStyle   = TBSTYLE_BUTTON;
	Button[11].idCommand = MENU_SEARCH_REPLACE;

	Button[12].fsStyle   = TBSTYLE_SEP;

	Button[13].iBitmap   = STD_HELP;
	Button[13].fsState   = TBSTATE_ENABLED;
	Button[13].fsStyle   = TBSTYLE_BUTTON;
	Button[13].idCommand = MENU_HELP_TOPIC;

	SendMessage(hTool, TB_ADDBUTTONS, 14, (LPARAM) &Button);
}

I would like to change Button[13] to a Bitmap loaded as a resource. Does anyone know how to do this? I tried just changing the iBitmap part of the structure, but this did not work.

Thanks.

Actually changing the iBitmap is what you have to do. But this part is kinda weird, you need to have your resource name for you image have a #defines with a number. Like this:

Code:

#define my_toolbar_image 150
my_toolbar_image BITMAP "C:/image.bmp"

It has been my experience that this works.

I don't really understand. I thought iBitmap was the zero based index of the bitmap image. I think my problem is that I am trying to have some images be the STD_<imageName> kind and others being custom images that are stored as bitmap resources. I don't know if you can combine these two into one toolbar.

In that case, I don't think you can use standard images and your images both in the same toolbar. You can make multiple toolbars though.

Toolbars store and manipulate their images in an imagelist control. In order to 'mix & match' as you have described you need to kill off the current toolbar imagelist and create another that contains the images you require. You attach this new imagelist to the toolbar and access the images in exactly the same manner as previously.

You can use the TB_SETIMAGELIST to both set the new and retrieve the old imagelist, eg.:

Code:

ImageList_Destroy((HIMAGELIST)SendMessage(hToolbar,TB_SETIMAGELIST,0,(LPARAM)NewImageList);

where hToolbar is your toolbar handle and NewImageList is the handle of the new imagelist.

One way to get the default images from comctl32.dll is to use LoadLibrary to get an instance handle; use LoadImage with this handle and the image resource id to retrieve handles to the images. Get image handles for your own image(s) using your preferred loading technique and add them to your new image list. Don't forget to FreeLibrary when you're done with comctl32.dll.

Hope that helps some.

That is a very good idea! Good thinking Ken.
