Forget the "not relevant" part, because conditions are not satisfied for it
to be executed.
What I experience is that
when the app starts in landscape mode (simulator was intentionally left in
that state)
the user interface correctly displays just the master container at full
screen (so the detail container is not added yet)
if I juggle with orientation changes the two modes correctly alternate
but the app starts in portrait mode (simulator was intentionally left in
that state)
when an orientation change occurs
and now the simulator is in landscape mode
(containers are removed)
I see that the master detail TableLayout is not working because just the
master container is at full screen.
if I juggle with orientation changes nothing changes.
Debug shows that the right code is executed at orientation change, that is
if(isTablet() && !isPortrait() )
{
...
}
If I step into, I see that mainForm has BorderLayout and not TableLayout:
CallingForm[x=0 y=0 width=2048 height=1534 name=null, layout =
BorderLayout, scrollableX = false, scrollableY = false, components =
[Container, Toolbar], title = Label[x=0 y=47 width=1536 height=0 name=null,
text = , gap = 2], visible = true]
but at startup this is executed (I tried also executing it every time, see
commented lines)
tl=new TableLayout(1,2);
mainForm.setLayout(tl);
mainForm.setScrollable(false);
I see also
Exception in thread "AWT-EventQueue-0" Failed to get location on
screen:component must be showing on the screen to determine its location
in the console after the execution of the method.
