Hi,

I have the following code:
Code:
 _LIT(was,"SynbianTextbox");

 CEikEdwin *iEdwin1 = new (ELeave) CEikEdwin();
 iEdwin1->ConstructL(EEikEdwinNoWrap,10,16,1);
 iEdwin1->SetContainerWindowL(*this);
 iEdwin1->SetExtent(TPoint(10,10), TSize(100,25));
 iEdwin1->SetTextL(&was);
 iEdwin1->SetFocus(ETrue);
 iEdwin1->SetBackgroundColorL(TRgb(255,0,0));

 CEikLabel *iLabel  = new( ELeave )CEikLabel();
 iLabel->SetContainerWindowL( * this );
 iLabel->SetTextL(_L("tectfeidlcpp"));
 iLabel->SetRect( Rect() );
 iLabel->SetExtent(TPoint(20,40),TSize(100,120));
 iLabel->DrawNow();
 iLabel->ActivateL();

 

But besides a blinking cursor, nothing is shown on the screen, the this-pointer is the container of my application. Whats's wrong?

After this view, I would like to display a list, which is already working.
Should I just delete the old controls, draw the list over the other controls, clear the screen? What is the correct method for this?

Thanks a lot for your help

i've added the correct number of controls (2 controls). the strange thing is that if i try to add different text to the editor control, the blinkin' cursor blinks at different position, so it seems that it writes the output on the editor control but it doesn't display it

if u see label then just add any one of the  following line

iEdwin->ActivateL()

or
remove iLabel->ActivateL()
and add
just
ActivateL()

this is my code in the ConstructL of my control (CTestoDizionario):

SetContainerWindowL(*aParent);

// iAppTitle
iAppTitle=CCknAppTitle::NewL(CCknAppTitle::EWindow);
iAppTitle->SetContainerWindowL(*this);
iAppTitle->SetTextL(_L("titolo"),CCknAppTitle::EMainTitle);

// editor
iEditor=new(ELeave)CEikEdwin(TGulBorder::ESingleBlack);
iEditor->ConstructL(0,0,0,0);
iEditor->SetContainerWindowL(*this);
iEditor->SetRect(TRect(30,30,100,100));
TBuf<100> text;
text.Format(_L("Line 1"));
text.Append(CEditableText::ELineBreak);
text.Append(_L("Line 2"));     
iEditor->SetTextL(&text);
iEditor->SetFocus(ETrue,EDrawNow);

if i add iEditor->ActivateL(); or iAppTitle->ActivateL(); nothing changes... note that i recall this function form the appView:

CreateWindowL();
// CTestoDizionario
iTestoDizionario=new(ELeave)CTestoDizionario();
iTestoDizionario->ConstructL(this);
iTestoDizionario->SetBorder(TGulBorder::EWindow);
SetRect(aRect);
ActivateL();

remove  following lines and check out:
text.Format(_L("Line 1"));
text.Append(CEditableText::ELineBreak);

many ppl are complaining there is prob with CEditableText::ELineBreak
so i think it would be the reason

Last suggestion:
write CreateWindowL();  as the first line of ConstructL()
instead in between

One more suggestoin  Tongue

remove it
TGulBorder::ESingleBlack

When i was working on series80, setting border to listbox resulted in not displaying text in listbox. So it may be the case with u.
