Button TABSTOP in ownerdraw not working - mfc

Question

I created a custom button class CMyButton inherited from CButton, then I am using the DrawItem to customize the button.
Using the custtom button, I created 3button on dialog.
The issue is that the TAB key for the button is not working. If I remove drawitem then there is no issue. Can anyone please help on this?
void CMyButton::DrawItem(LPDRAWITEMSTRUCT lpDrawItemStruct)
{
CDC* pDC = CDC::FromHandle(lpDrawItemStruct->hDC);
CRect rect = lpDrawItemStruct->rcItem;
UINT state = lpDrawItemStruct->itemState;
pDC->DrawFrameControl(rect, DFC_BUTTON , DFCS_BUTTONPUSH | DFCS );
pDC->FillSolidRect(rect, RGB(24, 72, 76));
pDC->SetTextColor(RGB(255, 255, 255));
CString strText;
GetWindowText(strText);
pDC->DrawText(strText,rect, DT_SINGLELINE | DT_CENTER | DT_VCENTER);
}

Answer 1

I doubt it. If you make a button owner draw, then you are responsible for drawing it all the time. This includes the focused state, etc. See the documentation for DRAWITEMSTRUCT.itemstate.

The focus rectangle is automatically rendered for standard controls on a dialog. If you subscribe to owner-drawing, responsibility to render visual cues is shifted to the custom implementation. While TABbing still works, keyboard focus remains invisible unless the implementation explicitly accounts for it.
You can use the DRAWITEMSTRUCT passed to your DrawItem method to query the item's state. If itemState contains the ODS_FOCUS flag, the control being rendered has the keyboard focus, and should produce the desired visual cue.
As a simple illustration, replace your call to FillSolidRect with the following code:
if ( state & ODS_FOCUS )
// Control has keyboard focus -> render it green
pDC->FillSolidRect( rect, RGB( 0, 255, 0 ) );
else
// Control doesn't have keyboard focus -> render it red
pDC->FillSolidRect( rect, RGB( 255, 0, 0 ) );
This allows you to see, that the TAB key does work as expected: The button control with keyboard focus is rendered green, whereas all other buttons are red.
If you are looking for a more standard appearance you can call CDC::DrawFocusRect (or DrawFocusRect) instead.
