Display and Refresh Text

[freak82]

I need to display and refresh a text value, but I can't seem to make this simple thing work...
I tried with ICaptionControl and calling inside the loop:

  // loop
  freq = GetFreq();
  if (GetGUI())
    {
      GetGUI()->SetParameterFromPlug(kICaptionControl,freq, false);
    }
  InformHostOfParamChange(kICaptionControl, freq);

but it keeps showing the default value.
Can someone help me?

her you are...

class IValueReadOut : public IControl
{
public:
    
    IValueReadOut(IPlugBase* pPlug, IRECT pR)
    : IControl(pPlug, pR)
    {
        mColor = IColor(255,87,87,87); //For later FilledRect()
        
    }

    ~IValueReadOut() {}
    
    bool Draw(IGraphics* pGraphics)
    {

        
        IText txt = IText(&COLOR_WHITE);
        IRECT readout = IRECT(mRECT.L, mRECT.T, mRECT.R , mRECT.B );
                
        char result[100];

        sprintf(result, "%.1f", mValue); 

            pGraphics->DrawIText(&txt, result, &readout);   
       
        return true;
    }
    
    bool IsDirty() { return true;}
    
protected:
    IColor mColor;
};
