hello ,

Here's a script corrected for viewing graphically the different layout on the screen

EDIT
PS :

Caution : the PyS60 has a bug you must use 2 argument in the resize callback function instead of one 2 element tuple
else you have this :

When I switch screen in landscape mode on my N93 I have a strange error :

TypeError:resize() takes exatly 1 argument (2 given)

But doc says :
resize_callback is called when screen size is changed when the Canvas rect size has been changed.
The callback takes as its argument a two-element tuple that contains the new clientRect width and height.

What is the right argument for callback_resize argument

Thanks Cyke64

Hi cyke64,

It seems from the source

void 
CAppuifwCanvas::SizeChanged()
{ 
  PyObject *arg=NULL, *ret=NULL;
  if (iResizeCallback) {
    int in_interpreter=(_PyThreadState_Current == PYTHON_TLS->thread_state);
    if (!in_interpreter) {
      PyEval_RestoreThread(PYTHON_TLS->thread_state);
    }
    PyObject *pyrectsize=Py_BuildValue("(ii)", Rect().Width(), Rect().Height());
    app_callback_handler( iResizeCallback, pyrectsize);
  	if (!in_interpreter) {
        PyEval_SaveThread();
    }
  }
}

That that it might return a 2 elements tuple. I don't really get it nether why, but in fact I guess you get at first the width then the height. I just change your script as below and it works with no errors

def resize( aWidth=None, aHeight=None ):
    print "width:", aWidth
    print "height:", aHeight

    if ( aWidth==w ) and ( aHeight==h ):
        print "Landscape"
        appuifw.note( u'Landscape !', 'info', 1 )
    else:
        print "Portrait"
        appuifw.note( u'Portrait !', 'info', 1 )

Still I'm not 100% sure. Needs to be confirmed!

hello ,

Thanks for your answer

void 
CAppuifwCanvas::Draw(const TRect& aRect) const
{     
  if (iDrawCallback) {
    int in_interpreter=(_PyThreadState_Current == PYTHON_TLS->thread_state);
    if (!in_interpreter)
      PyEval_RestoreThread(PYTHON_TLS->thread_state);
    PyObject *pyrect=Py_BuildValue("((iiii))",
				   aRect.iTl.iX,
				   aRect.iTl.iY,
				   aRect.iBr.iX,
				   aRect.iBr.iY);
    app_callback_handler(iDrawCallback,pyrect);
    Py_DECREF(pyrect);
    if (!in_interpreter)
      PyEval_SaveThread();
  } else {
    CWindowGc& gc=SystemGc();    
    gc.SetBrushColor(KRgbWhite);
    gc.Clear(Rect()); 
  }
}

If you look at the code above you see that redraw_callback return a four-element tuple "((iiii))" and resize_callback logically must return a two-element tuple "((ii))" but there's a BUG it return only 2 elements "(ii)"

So it could be filled as a bug in the tracker ???

Sweet, we learn everyday

I submited the bug in the tracker

Good point. Thanks for the report.

hello ,

Here are some results from N93 testing :

in landscape mode :
all portrait ids work except context pane id and all landscape ids work !

in portrait mode :
all portrait ids work and only landscape control pane top and status pane top work !

Have you the same result on N90 by example ???

Does this only work on 3rd edition?
I installed 1.3.17 on 2nd and it doesnt work .

I installed 1.3.17 on 2nd and it doesnt work .

If you have used my new script and if this does'nt work it's normal thing because you haven't the right phone in the 2nd edition (only N70 and N90)
Have you read the official doc ???
Have you read these lines in the script preventing you from doing stupids things

info_edition=e32.s60_version_info
if info_edition==(2,8) or info_edition[0]>=3:
  runz=1

Ok, I just tested it quickly to see what it is. Now i know .
