Upgrading Toolkit Standard to Toolkit Pro -
Create a custom theme for your application

1. Create a new class derived from one of the predefined themes found in the toolkit. We are going to use CXTPDefaultTheme, however you can use any of the following theme classes:

   CXTPDefaultTheme to inherit Office 2000 theme
   CXTPOfficeTheme to inherit Office XP theme
   CXTPOffice2003Theme to inherit Office 2003 theme
   CXTPNativeXPTheme to inherit Native XP theme

   class CDoubleGripperTheme : public CXTPDefaultTheme
   {
   
   };
   

2. Override the DrawCommandBarGripper of CXTPDefaultTheme base class (See XTPPaintManager.h). This will allow us to add our own custom look for drawing the command bar grippers

   class CDoubleGripperTheme: public CXTPDefaultTheme
   {
   virtual CSize DrawCommandBarGripper(CDC* pDC, CXTPCommandBar* pBar, BOOL bDraw);
   };
   
   [...]
   
   // DrawCommandBarGripper function. 
   // if bDraw if FALSE must return gripper size.
   // if bDraw is TRUE must draw gripper.  
   CSize CDoubleGripperTheme::DrawCommandBarGripper(CDC* pDC, CXTPCommandBar* pBar, BOOL bDraw)
   {
       // If Toolbar is vertical docked
       if (pBar->GetPosition() == xtpBarRight ||
           pBar->GetPosition() == xtpBarLeft)
       {
           if (bDraw)
           {
               CXTPClientRect rc(pBar);
               Draw3dRect(pDC, CRect(3, 3, rc.right - 3, 6),
                   COLOR_BTNHILIGHT, COLOR_3DSHADOW);
               Draw3dRect(pDC, CRect(3, 7, rc.right - 3, 10),
                   COLOR_BTNHILIGHT, COLOR_3DSHADOW);
           }
           return CSize(0, 10);
       }
       // if Toolbar is horizontal  docked 
       else
           if (pBar->GetPosition() == xtpBarTop ||
               pBar->GetPosition() == xtpBarBottom)
           {
               CXTPClientRect rc(pBar);
               if (bDraw)
               {
                   Draw3dRect(pDC, CRect(3, 3, 6,
                       rc.bottom - 3),
                       COLOR_BTNHILIGHT, COLOR_3DSHADOW);
                   Draw3dRect(pDC, CRect(7, 3, 10,
                       rc.bottom - 3),
                       COLOR_BTNHILIGHT, COLOR_3DSHADOW);
               }
               return CSize(10, 0);
           }
           else return CXTPDefaultTheme::
               DrawCommandBarGripper(pDC, pBar, bDraw);
   }
   

3. Call CXTPPaintManager::SetCustomTheme from CMainFrame::OnCreate method to use the theme we just created

   int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
   {
       ...
   
           // Use our own theme for drawing 
           // command bar grippers.
           CXTPPaintManager::SetCustomTheme(
               new CDoubleGripperTheme());
   
       return 0;
   }
