Re: CTabCtrl in CSplitterWindow

Hi Jochen,

in stdafx.h
#define _WIN32_WINNT 0x0600


instead of CTabCtrl use:

// CMyTabCtrl: explicit handling of WM_ERASEBKGND when themed
#include <atltheme.h>

class CMyTabCtrl : 

public CWindowImpl<CMyTabCtrl, CTabCtrl>,

public CThemeImpl<CMyTabCtrl>

{

public:

DECLARE_WND_SUPERCLASS(_T("MyTabCtrl"), CTabCtrl::GetWndClassName())

CMyTabCtrl()

{

SetThemeClassList(VSCLASS_TABSTYLE);

}

BEGIN_MSG_MAP(CMyTabCtrl)

CHAIN_MSG_MAP(CThemeImpl<CMyTabCtrl>)

MESSAGE_HANDLER(WM_ERASEBKGND, OnEraseBackground)

END_MSG_MAP()

LRESULT OnEraseBackground(UINT /*uMsg*/, WPARAM wParam, LPARAM /*lParam*/, BOOL& /*bHandled*/)

{

if (IsThemingSupported())

{

RECT rc = {0};

GetClientRect(&rc);

DrawThemeBackground((HDC)wParam, TABP_PANE, TIS_NORMAL, &rc);

}

else 

bHandled = FALSE; // not handled

return 1;

}

};

// in CMainFrame declaration
CMyTabCtrl mTab1, mTab2;


Not very pleasant solution, but working.

cheers,
AR

  Subject: [wtl] CTabCtrl in CSplitterWindow





  I having a problem with a CTabCtrl in a CSplitterWindow when I am using Common Controls 6.0.0.0. The area where the tabs are located is not being redrawn properly when I move the splitter. The tabs themselves are redrawn but not the area next to them. Here is a picture of what I mean (http://www.geist3d.com/images/wtl.jpg). The code that produces this problem seems quite simple:

  class FrmTest : public CFrameWindowImpl<FrmTest> 
  {
  public:

  DECLARE_FRAME_WND_CLASS(NULL, IDR_MAINFRAME)

  BEGIN_MSG_MAP(FrmTest)
  MESSAGE_HANDLER(WM_CREATE, OnCreate)
  CHAIN_MSG_MAP(CFrameWindowImpl<FrmTest>)
  REFLECT_NOTIFICATIONS()
  END_MSG_MAP()

  LRESULT OnCreate(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled);

  CTabCtrl mTab1;
  CTabCtrl mTab2;

  CSplitterWindowT<false> mHorizontalSplitter;
  } 

  LRESULT FrmTest::OnCreate(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled)
  {
  LRESULT lRes = DefWindowProc(uMsg, wParam, lParam);
  CRect lRect;
  GetClientRect(&lRect);

  // Splitters
  m_hWndClient = mHorizontalSplitter.Create(m_hWnd, lRect, NULL, 0, WS_EX_CLIENTEDGE);
  mHorizontalSplitter.SetSplitterExtendedStyle(SPLIT_BOTTOMALIGNED);

  mTab1.Create (mHorizontalSplitter, rcDefault, NULL, WS_CHILD | WS_VISIBLE | TCS_BOTTOM);
  mTab2.Create (mHorizontalSplitter, rcDefault, NULL, WS_CHILD | WS_VISIBLE );

  TC_ITEM lTab; 
  lTab.mask = TCIF_TEXT; 
  lTab.pszText = _T("Scene"); 
  lTab.cchTextMax = _tcslen(lTab.pszText); 
  mTab1.InsertItem(0,&lTab); 
  mTab2.InsertItem(0,&lTab); 

  lTab.mask = TCIF_TEXT; 
  lTab.pszText = _T("Petri"); 
  lTab.cchTextMax = _tcslen(lTab.pszText); 
  mTab1.InsertItem(1,&lTab); 
  mTab2.InsertItem(0,&lTab); 

  mHorizontalSplitter.SetSplitterPanes(mTab1, mTab2);

  UpdateLayout();

  mHorizontalSplitter.SetSplitterPos(150);
  mHorizontalSplitter.m_bFullDrag = false;

  return 0;
  }

  This problem only occurs when I switch to Common Controls 6.0.0.0 in the stdafx.h. I.e. using 

  #pragma comment(linker, "/manifestdependency:\"type='win32'name='Microsoft.Windows.Common-Controls' version='6.0.0.0' processorArchitecture='x86' publicKeyToken='6595b64144ccf1df' language='*'\"")

  Cheers
  Jochen
