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

Author: Kirk Stowell
Platform: Visual C++ MFC
  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;
    }
