How to create a floating window and detect touch event

[SymNewbi]

I created a floating window with this code, but i don't know how to detect when user touches it, or to get pointer position on this window when user touches it.

   User::LeaveIfError(ws.Connect());
    screen = new(ELeave) CWsScreenDevice(ws);
    screen->Construct();
 
    RWindowGroup wg(ws);
    User::LeaveIfError(wg.Construct(reinterpret_cast<TUint32>(&wg), EFalse));
    CleanupClosePushL(wg);
 
    wg.SetOrdinalPosition(10, ECoeWinPriorityAlwaysAtFront);
 
    CWindowGc* gc;
    User::LeaveIfError(screen->CreateContext(gc));
    CleanupStack::PushL(gc);
 
    RWindow window(ws);
    User::LeaveIfError(window.Construct(wg, reinterpret_cast<TUint32>(&wg) + 1));
    CleanupClosePushL(window);
    window.SetBackgroundColor(TRgb(0x90, 0x90, 0x90));
    window.Activate();
    window.SetExtent(TPoint(0, 0), TSize(50, 300));
    window.SetVisible(ETrue);
    
    gc->Activate(window);
 
 
    TRect rect = TRect(window.Size());
    window.Invalidate(rect);
    window.BeginRedraw(rect);
 
    gc->SetBrushStyle(CGraphicsContext::ESolidBrush);
    gc->Clear();


    gc->SetBrushColor(TRgb(0, 255, 0));
    gc->DrawRect(rect);
   
 
    window.EndRedraw();
    gc->Deactivate();
 
    ws.Flush();

thanks.

You should check HandlePointerEventL()... it will let you know of the touch events.

[SymNewbi]

But how could I bind iWindow with HandlePointerEventL() ??

Is there a function under RWindow I can pass it a callback object to receive pointer event??

[symbianyucca]

Yep, she basically though that you are using normal application framework. anyway, you should first make a real class instance for handling the screen and derive it from CActive, a bit like this: http://www.developer.nokia.com/Commu...tion_framework

then you could use the RWsSession's EventReady (instead of the example RedrawReady) to catch all events, also do remember to enable focus for your window.

Also look at the following method : RWindow::SetPointerCapture()

hi guys, and girls,

I managed to get my code work , and i can detect when user touches the window, and the (x,y) point.

My problem is, how to detect when user touches the screen out of my floating window, so I can dismiss it?

[symbianyucca]

if you plan to disable the screen, you should make transparent window that fills the whole screen.

[SymNewbi]

No, I'm not planning to disable the whole screen, i just want to show my floating window ( it will be as a task bar, in screen corner ), and if user clicks it, it will launch an application and disappear, and if user click out / away from my window, it will just disappear.

[symbianyucca]

So in that case you could also use the method I descriped, then of cource the touch event used for the dismissing would be lost, unless you find a way to forward it.

How did you get it working, could you please share some of the code with me(us) as I am trying to make something similar.

[symbianyucca]

You could maybe just try out the code in the link, and then describe what the problem you still have is.
