    Posted: 04 April 2016 at 9:02am
I just added Visual Studio 2015 theming support to CXTPTabCtrl.

To do it, add this lines to VisualStudio2015Blue.ini:

[TabCtrl]
BackSelected = 255 255 255
Back = 91 113 153
Border = 142 155 188
TextSelected = 0 0 0
Text = 255 255 255

Add this lines to VisualStudio2015Dark.ini

[TabCtrl]
BackSelected = 37 37 38
Back = 45 45 48
Border = 63 63 70
TextSelected = 51 153 255
Text = 241 241 241

and add this lines to VisualStudio2015Light.ini

[TabCtrl]
BackSelected = 245 245 245
Back = 238 238 242
Border = 204 206 219
TextSelected = 51 153 255
Text = 0 0 0

and compile the VisualStudio2015 solution.

Then, add the next lines to XTPTabBase.cpp in method BOOL CXTPTabBase::SetTheme(XTPControlTheme eTheme):

 case xtpControlThemeVisualStudio2015:
  m_pTheme = new CXTPTabCtrlThemeVisualStudio2015;
  break;

Add this lines in XTPTabBaseTheme.h, after declaration of CXTPTTabBaseTheme:

class _XTP_EXT_CLASS CXTPTabCtrlThemeVisualStudio2015 : public CXTPTabBaseTheme
{
private:
 CXTPPaintManagerColor back;
 CXTPPaintManagerColor backSelected;
 CXTPPaintManagerColor text;
 CXTPPaintManagerColor textSelected;
 CXTPPaintManagerColor border;
public:
 CXTPTabCtrlThemeVisualStudio2015();

protected:
 virtual void RefreshMetrics(CTabCtrl* pTab);
 virtual void DrawBorders(CDC* pDC, const CRect& rcClient);
 virtual void DrawTabCtrl(CDC* pDC, CXTPTabBase* pTabCtrl);
 virtual void FillTabFace(CDC* pDC, CTabCtrl* pTabCtrl, CRect rcItem, BOOL bSelected);
 virtual void DrawTabText(CDC* pDC, CTabCtrl* pTabCtrl, CRect& rcItem, int iItem, BOOL bSelected, BOOL bBoldFont);
};

and finally add this lines to XTPTabBaseTheme.cpp:

CXTPTabCtrlThemeVisualStudio2015::CXTPTabCtrlThemeVisualStudio2015()
{
 m_bUseWinThemes = FALSE;
 m_bSystemDrawing = FALSE;
}

void CXTPTabCtrlThemeVisualStudio2015::RefreshMetrics(CTabCtrl* pTab)
{
 __super::RefreshMetrics(pTab);

 backSelected = XTPIniColor(_T("TabCtrl"), _T("BackSelected"), RGB(253, 253, 253));
 back = XTPIniColor(_T("TabCtrl"), _T("Back"), RGB(253, 253, 253));
 border = XTPIniColor(_T("TabCtrl"), _T("Border"), RGB(253, 253, 253));
 textSelected = XTPIniColor(_T("TabCtrl"), _T("TextSelected"), RGB(253, 253, 253));
 text = XTPIniColor(_T("TabCtrl"), _T("Text"), RGB(253, 253, 253));
}

void CXTPTabCtrlThemeVisualStudio2015::DrawTabCtrl(CDC* pDC, CXTPTabBase* pTabCtrlBase)
{
 CTabCtrl* pTabCtrl = pTabCtrlBase->GetTabCtrlImpl();

 CXTPClientRect rcClient(pTabCtrl);
 pDC->FillSolidRect(rcClient, back);

 DrawBorders(pDC, rcClient);

 if (pTabCtrl->GetItemCount() != 0)
 {
  for (int iItem = 0; iItem < pTabCtrl->GetItemCount(); ++iItem)
   DrawTab(pDC, pTabCtrlBase, iItem);

  DrawTab(pDC, pTabCtrlBase, pTabCtrl->GetCurSel());

  ShowButtons(pTabCtrlBase);

  if (pTabCtrlBase->m_bXPBorder)
  {
   CRect rcChild;
   pTabCtrlBase->GetChildRect(rcChild);
   rcChild.InflateRect(1, 1);
   DrawBorder(pDC, rcChild);
  }
 }
 else
 {
  ShowButtons(pTabCtrlBase);
 }
}

void CXTPTabCtrlThemeVisualStudio2015::DrawBorders(CDC* pDC, const CRect& rcClient)
{
 CRect rcBorder = rcClient;

 if (m_bUseWinThemes && m_themeTab->IsAppThemeReady())
 {
 }
 else
 {
  VerticalLine(pDC, rcBorder.left, rcBorder.top, rcBorder.Height(), border);
  VerticalLine(pDC, rcBorder.right - XTP_DPI_X(1), rcBorder.top, rcBorder.Height(), border);
  HorizontalLine(pDC, rcBorder.left, rcBorder.top, rcBorder.Width(), border);
  HorizontalLine(pDC, rcBorder.left, rcBorder.bottom - XTP_DPI_Y(1), rcBorder.Width(), border);
 }
}

void CXTPTabCtrlThemeVisualStudio2015::FillTabFace(CDC* pDC, CTabCtrl* pTabCtrl, CRect rcItem, BOOL bSelected)
{
 DWORD dwStyle = GetTabStyle(pTabCtrl);

 if (IsRight(dwStyle))
 {
  if (bSelected)
   pDC->FillSolidRect(&rcItem, backSelected);
  else
   pDC->FillSolidRect(&rcItem, back);

  HorizontalLine(pDC, rcItem.left, rcItem.top, rcItem.Width(), border);
  VerticalLine(pDC, rcItem.right, rcItem.top, rcItem.Height(), border);
  HorizontalLine(pDC, rcItem.left, rcItem.bottom, rcItem.Width(), border);
 }
 else if (IsLeft(dwStyle))
 {
  if (bSelected)
   pDC->FillSolidRect(&rcItem, backSelected);
  else
   pDC->FillSolidRect(&rcItem, back);

  HorizontalLine(pDC, rcItem.left, rcItem.top, rcItem.Width(), border);
  VerticalLine(pDC, rcItem.left, rcItem.top, rcItem.Height(), border);
  HorizontalLine(pDC, rcItem.left, rcItem.bottom, rcItem.Width(), border);
 }
 else if (IsBottom(dwStyle))
 {
  if (bSelected)
   pDC->FillSolidRect(&rcItem, backSelected);
  else
   pDC->FillSolidRect(&rcItem, back);

  VerticalLine(pDC, rcItem.left, rcItem.top, rcItem.Height(), border);
  HorizontalLine(pDC, rcItem.left, rcItem.bottom, rcItem.Width(), border);
  VerticalLine(pDC, rcItem.right, rcItem.top, rcItem.Height(), border);
 }
 else
 {
  if (bSelected)
   pDC->FillSolidRect(&rcItem, backSelected);
  else
   pDC->FillSolidRect(&rcItem, back);

  VerticalLine(pDC, rcItem.left - XTP_DPI_X(2), rcItem.top - XTP_DPI_Y(2), rcItem.Height(), border);
  HorizontalLine(pDC, rcItem.left, rcItem.top - XTP_DPI_Y(2), rcItem.Width(), border);
  VerticalLine(pDC, rcItem.right - XTP_DPI_X(2), rcItem.top - XTP_DPI_Y(2), rcItem.Height(), border);
 }
}

void CXTPTabCtrlThemeVisualStudio2015::DrawTabText(CDC* pDC, CTabCtrl* pTabCtrl, CRect& rcItem, int iItem, BOOL bSelected, BOOL bBoldFont)
{
 TCHAR szLabel[256];
 szLabel[0] = 0;

 TC_ITEM tci;
 tci.mask = TCIF_TEXT;
 tci.pszText = szLabel;
 tci.cchTextMax = _countof(szLabel);

 if (pTabCtrl->GetItem(iItem, &tci))
 {
  int nLen = (int)_tcslen(szLabel);
  if (nLen > 0)
  {
   pDC->SetBkMode(TRANSPARENT);
   pDC->SetTextColor(bSelected ? textSelected : text);

   // Set the font for the tab label.
   DWORD dwStyle = GetTabStyle(pTabCtrl);
   CXTPFontDC font(pDC, (bBoldFont && bSelected) ? (IsHorz(dwStyle) ? &XTPAuxData().fontBold : &XTPAuxData().fontVertBold) : (IsHorz(dwStyle) ? &XTPAuxData().font : &XTPAuxData().fontVert));

   // Draw the tab label.
   if (IsHorz(dwStyle))
   {
    pDC->DrawText(szLabel, nLen, rcItem, DT_SINGLELINE | DT_VCENTER | DT_CENTER | DT_END_ELLIPSIS);
   }
   else
   {
    CSize sz = pDC->GetTextExtent(szLabel, nLen);
    rcItem.left = rcItem.right - (rcItem.Width() - sz.cy + XTP_DPI_Y(1)) / 2;
    rcItem.top = rcItem.top + (rcItem.Height() - sz.cx + XTP_DPI_X(1)) / 2;

    pDC->DrawText(szLabel, nLen, &rcItem, DT_SINGLELINE | DT_NOCLIP);
   }
  }
 }
}

Then, you'll have something like this:
