Wrong NaviPaneText after orientation change

[dracula78]

Using the UI designer I made 3 views for my application, each with its own Navigation Pane Text (subtitle): "Main" (default, initial view), "History" and "Settings".

This works fine; every view shows its correct subtitle. However, the N95 can switch between portrait and landscape layout on-the-fly, and after changing this orientation, the subtitle is always set to "History", irregarding the current view. Only after switching the view, the correct subtitle is displayed again.

I can't figure out why only the subtitle is set incorrectly and the rest of the view is rotated properly. Do I need to do anything in my application to handle the orientation change? I did notice the view's HandleStatusPaneSizeChange and AppUI's HandleResourceChangeL get called...

Could you provide some more info. some code snippets would be good.

Hi,
I'm having the same trouble with a CAknForm class.

I handle the device orienation change like this:

void Take3FormNewForm::HandleResourceChange(TInt aType)
{
    CAknForm::HandleResourceChange(aType);

    //call base class implementation

   if ( aType==KEikDynamicLayoutVariantSwitch )
   {
	TRect rect;

	AknLayoutUtils::LayoutMetricsRect(AknLayoutUtils::EMainPane,rect);

	SetRect(rect);	

	CAknForm::DrawDeferred();
   }
}

The form gets updated just fine with the screen orienation EXCEPT for the TitlePane which retains some of the older orienation on it (same goes for the bottom bar sometimes) with what was there before, in the background.

To illustrate this, I've uploaded an image which you can see a *before* and *after* screenshot:

Please help me as I've sat on this for several hours without success :(

Hi. Here is a code snippet of what I have been doing to handle the screen orientation change. Hope it helps.

void CMyAppUi::HandleResourceChangeL(TInt aType)
{
CAknAppUi::HandleResourceChangeL(aType);
if(aType == EEikDynamicLayoutVariantSwitch)
{
iMyView->HandleClientRectChange();
}
}

void CMyView::iMyView->HandleClientRectChange()
{
if(iMyContainer) iMyContainer->SetRect(ClientRect());
}

void CMyContainer::Draw(const TRect& aRect) const
{
CWindowGc& gc = SystemGc();
/// Now you can either clear the screen or draw the back ground.
}

Still having problems :(

My application currently has 4 views, say, view1, view2, view3, view4, each with similarly-named title.

Views view1 and view2 are part of a AppUi tab group (they inherit the navigation pane from application.uidesign), view3 and view4 are separate settings screens accessible via menu options (they have a navigation title that overrides the application.uidesign).

I start in view1 and the 2 tabs are displayed properly in the navigation pane.

Next, I change the orientation to landscape using the N95's slidable display.
The view is properly updated, controls are properly aligned again, but the 2 tabs in the navigation pane have been replaced by the title "view4". Also when going back to portrait mode, the title "view4" remains visible, even when switching between tabs with the left/right button.
Even stranger: when I then go to view4 via the menu and return to view1, it uses the title "view3". When I then go to view3 and return to view1, it properly reverts to the tabs "view1" and "view2".

My questions: Where does it dig up the title "view4"? Can I manually refresh the navigation pane somehow? Could this be a bug in the generated code by the UI designer?

Hi Jini,
Can you please show me how to "draw the background"?

This is something that I've never learned how to do.
I currently save the background to a bitmap in the startup of the program, and draw that as the background when I need to.

Is there an easier way to do this?
Can you show me some code snippets?

Hi Dracula

I have a similar problem on N95 firmware v 12.0.013 (19-06-07)

Application in landscape mode : NaviPaneText OK
Switch portrait mode : NaviPaneText OK
Re-switch landscape mode : NaviPaneText KO

The NaviPaneText (bottom left rect) area seems filled with a previous video memory scrolled a little

Your post is old so, do you find a solution ?

Still looking for a solution myself, but my problem seems different: the navigation pane is properly refreshed, but simply contains the title of the wrong view after an orientation change.

I realize my example posted above was a bit overcomplicated, that's why I posted a simple complete project in another thread.

Looks like this problem was fixed in Carbide 1.3 UI Designer. The carbide 1.3 creates the following code which fixes the problem:

void ::HandleStatusPaneSizeChange()
{
   CAknView::HandleStatusPaneSizeChange();

   // this may fail, but we're not able to propagate exceptions 
   TVwsViewId view;
   AppUi()->GetActiveViewId(view);
   if (view.iViewUid == Id() )
   {
   TInt result;
   TRAP( result, SetupStatusPaneL() );
   }
}
