how to remove this error....in container.app

[bharats]

hi2 all
now that prblem is solved(i again went in recycle bin and restored the deleted .rsg file then it was builded successfully) but the new prblem is that ki when i am compiling my code and builded it my application first shows the blank screen for few seconds and then emulator automatically closec.

this is my container class modified code.

void CSMSExampleRTEContainer::ConstructL(const TRect& aRect)
{
CreateWindowL();
SetRect(aRect);
iRte = CRichTextEditorRTE::NewL();

TResourceReader reader;
iEikonEnv->CreateResourceReaderLC(reader,R_LIST_LISTBOX);
iListBox->ConstructFromResourceL(reader);
ActivateL();
CleanupStack::PopAndDestroy(); // reader
SizeChanged();
}

CSMSExampleRTEContainer::~CSMSExampleRTEContainer()
{
delete iRte;
iRte = 0;
}

void CSMSExampleRTEContainer::SizeChanged()
{
iListBox->SetExtent (TPoint(0,0), iListBox->MinimumSize());
}

TInt CSMSExampleRTEContainer::CountComponentControls() const
{
return 1; // return number of controls inside this container
}

CCoeControl* CSMSExampleRTEContainer::ComponentControl(TInt aIndex) const
{
switch ( aIndex )
{
case 0:
return iListBox;
default:
return NULL;
}
}


void CSMSExampleRTEContainer::Draw(const TRect& aRect) const
{
CWindowGc& gc = SystemGc();
gc.Clear(aRect);
}

void CSMSExampleRTEContainer::HandleControlEventL(
CCoeControl* /*aControl*/,TCoeEvent /*aEventType*/)
{
}
TKeyResponse CSMSExampleRTEContainer::OfferKeyEventL(const TKeyEvent& aKeyEvent,TEventCode aType)
{
if (iRte)
return iRte->OfferKeyEventL(aKeyEvent, aType);
else
return CCoeControl::OfferKeyEventL(aKeyEvent, aType);
}
void CSMSExampleRTEContainer::PlaySelectedGame(TInt /*aOpenedItem*/)
{
}


what should i do now?

awaiting your valuable reply......

TRy to debug the application and check what panic code you get..
search for the details related to the panic code.search in the sdk and also out here in FN.
if you are still stuck post it out here.it saves much of your time dude..

You're missing iListbox->SetContainerWindowL(*this); from ConstructL(). You might also want to remove SizeChanged from ConstructL, as it is called automatically. Also, maybe move ActivateL() as the last line in the ConstructL and place SetRect just before it.

[bharats]

hi 2 all

i have moved activateL at last and i putted setrect just before that
and i cant able 2 cal iListbox->SetContainerWindowL(*this);
because only CCoecontrol derived class is able 2 cal this method and iListbox objects class is not CCoecontrol derived.
and I removed sizechange method

till i am facing the same prblem.

do u hav any suggestion?

Hi,

Do like this,

First initialize ur listbox with CAknSingleStyleListBox or any other listbox style.

iListBox =  new(ELeave)  CAknSingleStyleListBox;
iListBox->SetContainerWindowL(*this);
TResourceReader reader;
iEikonEnv->CreateResourceReaderLC(reader,R_LIST_LISTBOX);
iListBox->ConstructFromResourceL(reader);
iListBox->ActivateL();
CleanupStack::PopAndDestroy(); // reader

And in OfferKeyEventL() function,

if(iRte)
return iRte->OfferKeyEventL(aKeyEvent,aType);
if(iListBox)
return iListBox->OfferKeyEventL(aKeyEvent,aType);

And in SizeChanged() function

if(iRte)
iRte->SetExtent(TPoint(0,0),iRte->MinimumSize());
if(iListBox)
iListBox->SetExtent(TPoint(0,0),iListBox->MinimumSize());

And change in CountComponentControls() and ComponentControl() functions also.

eswar

[bharats]

thanks eswar,

i have made the changes according to you.
now my emulator dosent dies but when i opens my application it is not showing any screens.

[bharats]

hi giridher,

thanks for reply.

yah i hav made changes in these two functions.
these are given below.

TInt CSMSExampleRTEContainer::CountComponentControls() const
{
return 2; // return number of controls inside this container
}


CCoeControl* CSMSExampleRTEContainer::ComponentControl(TInt aIndex) const
{
switch ( aIndex )
{
case 0:
return iRte;
case 1:
return iListBox;
default:
return NULL;
}
}


is it right?if not plz suggest me the right changes.

Hi barath,
your CountComponentControls() and ComponentControl() looks fine to me.( hope you have got two controls, ie.. richtextbox and a listbox).

like to know whats the panic code.usually the controls wont be shown in the container if the ComponentControls has a wrong count.but in your case i find it done pretty fine.please mention the panic code in your next post.

[bharats]

hi priju
thanks for reply.

actually i am not getting any error now.
i want my listbox to be shown on the first screen.but instead it is not showing the listbox it is showing the same main emulator screen from which i have selected my application with my two soft keys.
and when i pressed any softkey i am seeing the same menus which i have set for first screen.

awaiting your valuable reply.

Are you appending the correctly formatted items onto the list box.
If the format is wrong the list box items wouldnt be shown.
Check that.
And also you could try commenting your richtexteditors codes, and try for the listbox only.i think the richtexteditor is overlapping your listbox as for both you have set the same size and points.

Hi Bharat!

U try out wt giridharn n Priju Jacob Paul are saying.

I will advise u to go with only list control initially as Priju says.

At the same time see the listbox example from sdk.
crosscheck everything 1s again.

Tryin ur Draw(-)

gc.DrawRect( aRect );

instead of Clearing the whole window.

Also call
iListBox->DrawNow(); after iListBox->ActivateL();

call SetRect(aRect); after iListBox->ActivateL() and iListBox->DrawNow()

I think u r breaking the sequence.

Hope this helps u.
