Jumpy Text Class

Posted by Fabian Toader on December 2nd, 1999

Environment: VC6 SP2, NT4 SP5, CE 2.11

Sample Image This class is derived from CStatic and presents a special effect that will kick your ass. It is very simple to use and I hope you'll enjoy it very much. Here is how you use this class:

    1. Download the source code.
    2. Insert the .h and .cpp files into your project.
    3. Add a static control into your dialog resource.
    4. Add a member variable for that static control.
    5. Modify the varible declaration.
Change this: 

    CStatic m_ctrlYourStaticControl;
To this: 

    CJumpyDraw m_ctrlYourStaticControl;
    6. In your InitDialog message handler set the JumpyText parameters. Use these member functions: 

    SetCharHeight()
    SetText()
    7. When you want to start the animation call StartJumpyText.

    Dear sir,

    Can you help me to overcome the following problem:
    I want to have a static text control in VC++ 6.0 that has background transparent just like a label control in VB that has BackStyle set to TRANSPARENT. Because I want to use this static text to display text over an image background on a dialog box.
    Thanks for you help.

  • use float values in gradient generation

    Great modification of CStatic! Exactly what I was looking for - a gradient static control.

    But while using I recognized that gradient generation was not that precise. I changed the int values to float and used a casting in RGB() function.


    void CJumpyDraw::DrawLinearWash(CDC* pDC, CRect* prc, COLORREF crStart, COLORREF crEnd)

    {

       // Get the starting RGB values and calculate the incremental

       // changes to be applied.


       COLORREF cr;

       float iR = GetRValue(crStart);

       float iG = GetGValue(crStart);

       float iB = GetGValue(crStart);

       float idR = (GetRValue(crEnd) - iR) / (m_iGradientSteps - 1);

       float idG = (GetGValue(crEnd) - iG) / (m_iGradientSteps - 1);

       float idB = (GetBValue(crEnd) - iB) / (m_iGradientSteps - 1);

       int icx = prc->Width() / m_iGradientSteps, iLeft = prc->left, iRight;

       pDC->SelectStockObject(NULL_PEN);


       for (int i = 0; i < m_iGradientSteps; i++, iR += idR, iG += idG, iB += idB)

       {

          // Use special code for the last segment to avoid any problems

          // with integer division.


          if (i == (m_iGradientSteps - 1))

             iRight = prc->right;

          else

             iRight = iLeft + icx;


          cr = RGB((int) iR, (int) iG, (int) iB);

    		

          // The following extra stack frame allocates and disposes

          // of the GDI objects nicely.


          {

             // Perform the drawing and restore the DC; the objects

             // will be freed automatically.


             CBrush br(cr);

             CBrush* pbrOld = pDC->SelectObject(&br;);

             pDC->Rectangle(iLeft, prc->top, iRight + 1, prc->bottom);

             pDC->SelectObject(pbrOld);

          }

       // Reset the left side of the drawing rectangle.


          iLeft = iRight;

       }

    }


    I also added a member variable for the gradient steps (m_iGradientSteps) replacing the const int.
