Hi Experts,

Can anybody tell me that how to draw string, image etc apart from Draw() function.

Actually in my application i am requesting to server for data and i want to show message to user when server has finished work. So user can continue. For this i want to show some message to user but dont want to use DrawNow() because it call Draw() and i dont want to call Draw().

I heard about some functon BeginDraw() and EndDraw() but how to use them?

Please help me. Smiley

Re: How to draw string without using Draw()
Hi,

  Are you calling your own function from Draw()? If not, you have to call ActivateGc() before and DeactivateGc() after calling your own function, cause the standard graphics context needs to be activated and deactivated manually (in case of Draw() function these methods are called by the framework).
  If this is not the case, please provide some more information or source code.

Hope this helps,
  Damian

Re: How to draw string without using Draw()
Hi Damian,

Thanks very much for your reply. It helped me alot but my problem is not solved yet.
I am calling my function from CMyAppUi as -
Code:
void CMyAppUi::HandleCommandL(TInt aCommand)
    {
    switch ( aCommand )
        {
        case EAknSoftkeyBack:
{
iAppContainer->DrawMyText(_L("Hello My Text"));
break;
}
        case EEikCmdExit:
            {
            Exit();

break;
            }


and the problem is this is working only with case EAknSoftkeyBack, on other menu items it is not showing any thing.
my Draw function is -
Code:
void CMyContainer::DrawMyText(const TDesC &aText)
{
ActivateGc();
m_BufDrawText.Zero();
m_BufDrawText.Copy(aText);

CWindowGc &gc = SystemGc();
gc.Activate( Window() );
gc.UseFont( iCoeEnv->NormalFont() );
gc.DrawText( m_BufDrawText, TPoint( 30, 30 ) );
gc.Deactivate();
DeactivateGc();
}



for gc.Activate( Window() ); ....gc.Deactivate(); It is giving WSERV 10.


I want to work my DrawMyText() with any menu commmand...

hope u can help

thanks

Hi prj,
        here is the description for WSERV 10 panic
Quote
Attempted to activate an already active graphics context.

On the server side, this is raised by CWsGc::Activate() as a response to a EWsGcOpActivate request.

The request is sent by the client-side method CWindowGc::Activate().

I think you can comment the codes
gc.Activate( Window() ); and
gc.Deactivate();
and try....
hope this helps..

Re: How to draw string without using Draw()
O sorry Badshah ,

Actully that gc.Activate( Window() ); and gc.Deactivate(); is commented only, I just forgot to put the comment before putting in to forum.
ActivateGc();
DeactivateGc();
is working well but on system keys only like EAknSoftkeyBack not on my menu command

Re: How to draw string without using Draw()
Hi,

  I suggest you should take a look at helloworldplus example from Series60Ex. There is a custom draw method:
Code:
void CHelloWorldPlusAppView::UserDraw() const
However, behaviour you've described is strange. Could you show how (and where) are you invoking your custom draw method when it's not working?

  Damian
