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

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

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..
regards
Badshah

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,

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

gc.DrawText( ptext, TPoint( 10, 20 ) );
gc.Deactivate();
