Scroll down to see the controls drawn outside of ClientRect()!! Is it possible?

Hi
I want to draw some controls like CEikEdwin, CEikLabel, CEikSecreted etc.(there may be more than one control of a type). But the controls which are not drawn inside ClientRect(i.e the visible area of the mobile) are not shown. Can a scroll bar be put and we can scroll down to see the controls? or if any other way to do this. Any suggestions are appreciable. regards Satyajit |

I am explaining my problem once again. I am drawing controls dynamically. The new controls are drawn just vertically below the previous control. So after 6/7 controls the new control is drawn out side of the ClientRect(); i.e. visible area, but it is drawn. So the control is not shown. how can i show these controls?
Please help me. it is urgent..
thanx

I have drawn alternative Label and edwin controls dynamically. just changing the "noofctrl" to any integer that no of controls are drawn my code is as follows
The .cpp file
#include <eiklabel.h>
#include <eikedwin.h>
#include <barsread.h>
#include <badesca.h>
#include <eiktxlbm.h>
#include <test.rsg>
#include "testAppview1.h"
// Standard construction sequence
CtestAppview1* CtestAppview1::NewL(const TRect& aRect)
  {
  CtestAppview1* self = CtestAppview1::NewLC(aRect);
  CleanupStack::Pop(self);
  return self;
  }
CtestAppview1* CtestAppview1::NewLC(const TRect& aRect)
  {
  CtestAppview1* self = new (ELeave) CtestAppview1;
  CleanupStack::PushL(self);
  self->ConstructL(aRect);
  return self;
  }
CtestAppview1::CtestAppview1()
  {
// no implementation required
  }
CtestAppview1::~CtestAppview1()
  {
  for(TInt i=0;i<noofctrl;i++)
  {
  if(iCtrl[i])
  {
  delete iCtrl[i];
  iCtrl[i]=NULL;
  }
  }
// no implementation required
  }
void CtestAppview1::ConstructL(const TRect& aRect)
  {
  // Create a window for this application view1
  CreateWindowL();
  noofctrl=2;
  ycord = 5;
for(TInt i=0;i<noofctrl;i++)
{
if(i%2==0)
InitializeLabel(&iCtrl[i]);
else
InitializeEdwin(&iCtrl[i]);
}
iCtrl[1]->SetFocus(ETrue);
  // Set the windows size
  SetRect(aRect);
  // Activate the window, which makes it ready to be drawn
  ActivateL();
  }
// Draw this application's view1 to the screen
void CtestAppview1::Draw(const TRect& aRect) const
  {
  CWindowGc& gc = SystemGc();

  }

the .h file

  CtestAppview1();
private:
  CCoeControl* iCtrl[10];
  TInt noofctrl,ycord;
  };
#endif // __TEST_APPview1_H__
the problem is after the 3rd text box is drawn the next controls are drawn outside of the ClientRect and is not visible.
how to make those controls visible. Is some scrollbar can put to view those?
Is there any other way?
and also is there any easier way to draw dynamic controls?
Please help me
it is most urgent
thanx

let's consider u hv 10 ctrls of size 100 each. putting all ctrls in place size of container is sizeY = 1000.
call SetSize(TSize(Size().iWidth, sizeY) ) on container;
Now according to on which ctrl focus is, call SetPosition( TPoint(0, requiredPosition) ) on container
where requiredPosition veries to -100, -200, -300....
