Create a custom theme for your application

You can create a custom theme for your application by deriving a class from any of the theme classes available in the toolkit.

Create a double gripper theme similar to Visual Studio 6.0.

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);
            }
       }
       return CXTPDefaultTheme::DrawCommandBarGripper(pDC, pBar, bDraw);
    }
   

3. Call CXTPPaintManager::SetCustomTheme from CMainFrame's 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;
    }
