It's said in MSDN that:“
Microsoft Windows assumes that all of a toolbar's bitmapped images are the same size. ” So the question is :
How can we implement a toolbar?with different sized images, which is just like as Google Toolbar?
There are two ways:
1.To use double ImageLists
You should
note that the image's size of the toolbar is decided by?the first ImageList, even though the second one is different from the first one. So after registering double ImageLists, you also have to reset the button's size to suit the second imagelist.
This is the code segment:
a. setting double imagelist
????//1st?ImageList, with normal images
????m_hImage1st?=?ImageList_Create(16,?16,?ILC_COLOR24,?1,?0);
????int?nIdx11?=?ImageList_Add(m_hImageFirst,
,NULL);
????int?nIdx12?=??ImageList_Add(m_hImageFirst,,NULL);
????????//2nd?ImageList, with bigger image
????m_hImage2nd?=?ImageList_Create(48,?16,?ILC_COLOR24,?2,?0);
????int?nIdx21?=ImageList_Add(m_hImage2nd?,,NULL);
????//?add?imagelists, the order is very important
????::SendMessage(m_hWnd,?CCM_SETVERSION,?(WPARAM)?5,?0);
????::SendMessage(m_hWnd,?TB_SETIMAGELIST,?0,?(LPARAM)m_hImage1st);
????::SendMessage(m_hWnd,?TB_SETIMAGELIST,?1,?(LPARAM)m_hImage2nd);
????//?set?button?image
????pTBBtn[0].iBitmap?=?MAKELONG(nIdx21,?1);
????pTBBtn[1].iBitmap?=?MAKELONG(nIdx11,?0);
????pTBBtn[2].iBitmap?=?MAKELONG(nIdx12,?0);b. resize the button with bigger image
????TBBUTTONINFO?tbi;????????????
????tbi.cbSize?=?sizeof(TBBUTTONINFO);
????tbi.dwMask?=?TBIF_STYLE?|?TBIF_SIZE;
????tbi.fsStyle?=?pTBBtn[0].fsStyle;
????tbi.cx?=?48;
????????::SendMessage(m_hWnd,?TB_SETBUTTONINFO,?nID,?(LPARAM)&tbi); And now, ?the first button of the toolbar has different sized image from others.
2. To use Rebar controlA rebar?control?may have many toolbars, so you can create two toolbars with different sized imagelist.(See
MSDN.). But we can only create one toolbar in WTL by default, so it's a little complex to implement?using WTL in this method. You can try?this?in MFC.
