Background application and restoring like WhatsApp with QML

[Chechesa]

Hi all,

I've more than six months developing apps in Symbian ^3, and this is my first post here.

I've tried some solutions, and searched in blogs, code, etc. I was waiting for code in projects.developer.nokia.com pages but I didn't see examples of this there.

I need to do my app still running in background to show notifications. Then, for now my problem is minimize and restoring application.

I've minimized (with Qt showMinimize viewer, but this only minimize that window, not app). Then when I use Open Apps menu to restore my app, this simply doesn't work. App appears like front app but it shows nothing because window is minimized (or hidden, if I use hide).

Could you help me with some code for Symbian ^3/Anna?

Thanks!

I also have faced the same issue with Qt api. So I used symbian code and it work smoothly.

Thanks kkrish!

I used second link as base. That code makes application can't close (background for ever and ever).

After I did this (for reference to other users):

Next reference allows configure minimize button (a method, it can be integrated to QML).

#include <QtDeclarative>
#include <w32std.h>

in .h of my C++ class (to be integrated with QML) and next line in body of method which will be called from QML (p.e. a C++ method which will be called in ToolButton for hide/minimize).

CCoeEnv::Static()->RootWin().SetOrdinalPosition(-1);

In .pro add:

symbian { 
 
     LIBS += -lws32\
             -lcone
 
}

Only for further reference I think it can be improved, but it's fully functional in Symbian Anna tested on E7-00

Cheers!

cool.. but what will be the solution on MeeGo?

MeeGo apps are Components basaed and they don't live in real windows because they live in a GraphicsView (aka QDeclarativeView).
So you don't have this problem.
