你可以为程序制作自定义主题，通过继承toolkit中的任一主题类 。 源代码链接

通过继承toolkit中的任一可用的主题类，你可以制作自定义主题.
制作一个类似Visual Studio 6.0的双把手( gripper) 主题.

1. 新建一个类，派生自 toolkit中的预定义主题. 我们将使用CXTPDefaultTheme; 不过你也可以使用下面任何一个主题类::
   CXTPDefaultTheme 继承Office 2000 风格
   CXTPOfficeTheme继承Office XP 风格
   CXTPOffice2003Theme 继承Office 2003 风格
   CXTPNativeXPTheme 继承本地 XP 风格

   class CDoubleGripperTheme : public CXTPDefaultTheme
   {
       ...
   };
   

2. 覆盖 CXTPDefaultTheme 基类(查看XTPPaintManager.h)的DrawCommandBarGripper函数.  可以画命令栏把手添加定制外观:

   class CDoubleGripperTheme : public CXTPDefaultTheme
   {
       virtual CSize DrawCommandBarGripper(
           CDC* pDC, CXTPCommandBar* pBar, BOOL bDraw);
   };
   
   // DrawCommandBarGripper函数.
   //  bDraw 为假返回 gripper size.
   //  bDraw 为真，绘制gripper.
   CSize CDoubleGripperTheme::DrawCommandBarGripper(CDC *pDC, CXTPCommandBar *pBar, BOOL bDraw)
   {
     // If 工具栏垂直停靠    
     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 工具栏水平停靠    
     elseif (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. 在CMainFrame::OnCreate()方法中调用 CXTPPaintManager::SetCustomTheme 使用我们刚创建的主题风格:

   int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
   {
       ...
   
       //使用自己的主题风格绘制命令栏grippers.
       CXTPPaintManager::SetCustomTheme(new CDoubleGripperTheme());
       return 0;
   }

原文

1. Create a new class derived from one of the predefiend themes found in the toolkit. We are going to useCXTPDefaultTheme; 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 ofCXTPDefaultTheme base class (SeeXTPPaintManager.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 fromCMainFrame::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;
   }
