WM_DRAWITEM does not process for tab control
-
The following code works for me... Note you have to have a tab control subclassed by an object of your CTabCtrl-derived class, otherwise DrawItem() will never get called...
class CMyTabCtrl : public CTabCtrl
{
public:
CMyTabCtrl() : CTabCtrl() {}virtual void DrawItem(LPDRAWITEMSTRUCT /\*lpDrawItemStruct\*/);};
void CMyTabCtrl::DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct)
{
CDC dc;
dc.Attach(lpDrawItemStruct->hDC);// Note: My test tab control has two tabs inserted :) if (0 == lpDrawItemStruct->itemID) dc.DrawText(\_T("Tab 1"), &lpDrawItemStruct->rcItem, DT\_CENTER); else dc.DrawText(\_T("Tab 2"), &lpDrawItemStruct->rcItem, DT\_CENTER); dc.Detach();}

Thanks for ur help I created a dialog based application. I selected a tab control and moved to my dialog . I have created an MFC class named CMyTabCtrl derived from CTabCtrl. I added ur code to it. I created a member variable in the dialog class for the tab control using class wizard which is CMyTabCtrl m_Tab I have selected the owner draw fixed properties But still the drawitem of CMyTabCtrl does not called. Please implement this and if u r getting let me know what u did.

I did the same - I used a DDX_Control() call in DoDataExchange() to subclass the control...
void CMyDialog::DoDataExchange(CDataExchange* pDX)
{
CDialog::DoDataExchange(pDX);
DDX_Control(pDX, IDC_TAB1, m_Tab); <-- make sure you use the right ID!!!
