Landscape/Portrait orientation

[greumatt]

Hi @ all,

I have developed a small application, with some labels, which are drawn to the view. My problem is now, that if I change the view to Landscape, my lowermost label, is not anymore on the screen, because I have hardcoded the positions in pixel. I tried to figure out now, what view is activated and depending on it, draw the labels higher/more to the left, because now I have more room to fit 2 labels in one row, and wouldn't need to many rows, so everything fits on the screen again.

I have read some wiki pages about it, and searched in the forum and knowlege base, but I didn't find a solution to my prob.

I tried last the version with CCoeEnv, but this always returns me EAppUiOrientationUnspecified! :(

Here is my code, I'll try to handle it in the SizeChanged() funktion (maybe it's the wrong place to do this?):

void CTestProgramAppView::SizeChanged()
	{
	TInt yOffset = 0;

	CCoeEnv* env = CCoeEnv::Static();
	if( env )
	    {
	    CAknAppUiBase* appUiBase = REINTERPRET_CAST( CAknAppUiBase*, env->AppUi() );
	    if( appUiBase )
	        {
	        /* 
	        * Possible values for TAppUiOrientation are :
	        * EAppUiOrientationUnspecified,
	        * EAppUiOrientationPortrait,
	        * EAppUiOrientationLandscape,
	        * EAppUiOrientationAutomatic
	        **/
	        CAknAppUiBase::TAppUiOrientation orientation = appUiBase->Orientation();
	        if (orientation == CAknAppUiBase::EAppUiOrientationLandscape)
	        	{
	        	yOffset = 20;
	        	}
	        }
	    }
	
	
	iLabelHeading->SetExtent( TPoint(10,10), iLabelHeading->MinimumSize());
	iLabelHeadingText->SetExtent( TPoint(10 + 4* yOffset ,30 -yOffset), iLabelHeadingText->MinimumSize());
	
	// ... more labels follow

	iLabelAdditionalInformationText->SetExtent( TPoint(10,200 -yOffset), TSize(250,70));
	 
	DrawNow();
	}

What am I doing wrong? Thanks a lot in advance for your help!

Cheers,
Matt

p.s. I also tried it with:

void CScalableScreenDrawingControl::HandleResourceChange(TInt aType)
    {
    CCoeControl::HandleResourceChange(aType);
    if(aType == KEikDynamicLayoutVariantSwitch)
       {
       // ...
       }
    }

but here I just know, a view switch happened, and I still don't know if its portait or landscape...?!

You could try setting the new size in your HandleResourceChange() function..

thanks for you reply. :)

two questions to that:

I don't have implemented that function yet, I suppose it is called automatically? When?

And then I still don't know how to check which view I've got? I think the TAppUiOrientation will still be containing "EAppUiOrientationUnspecified" ?

It will be called by the framework whenever the layout switches.. You can now decide on the points to place the labels of your UI ...
You can well go thru the Scalable screen drawing example from FN to know its usage..

Hi,

I have implemented this HandleResourceChance() Function now in my AppUI class. It's like this:

void CAppUi::HandleResourceChangeL(TInt aType)
{
	CAknAppUi::HandleResourceChangeL(aType);

	if ( aType==KEikDynamicLayoutVariantSwitch )
		{		
                // Check if we are switched to Landscape Orientation
		if(this->Orientation() == CAknViewAppUi::EAppUiOrientationLandscape)
			{
                        // Temp: Show InformationNote to see, that if statement is correct
			HBufC* text = StringLoader::LoadLC(R_BLABLA_TEXT);
			CAknInformationNote *myInformationNote = new (ELeave) CAknInformationNote;
			myInformationNote->ExecuteLD(*text);
			CleanupStack::PopAndDestroy(text);
			}
	    }
}

So, all I won by now is, that I find out WHEN the orientation is changed. The second if statement still doesn't work. this->Orientation() still has the EAppUiOrientationUnspecified value!

I also checked out the Scalable_screen_drawing_how_to.pdf ... but all they say in this document is, how to find out WHEN the orientation is changed, and then they call

SetExtentToWholeScreen();

But full screen is not what I need... :(

Thanks again,

matt

Hey buddies,

I have solved the problem now, by toggling a TBool variable everytime i get a orientation switch event, and adjust my view depending on it. But it's a really unsatisfactionary/bad solution, this Orientation() function has to be working somehow, hasn't it?!

Cheers

UPDATE: This problem is not solved when the app started already in Landscape mode! So any help about the Orientation() function is appreciated. Thanks!!

Orientation is simply not the way, see paralel thread http://discussion.forum.nokia.com/fo...d.php?t=154853 (by the way: feel free to look around a bit prior to starting a new thread).
