Fullscreen : no StatusPane, no TitlePane but with CBA (Menu buttons)?

[NevenS]

Hello,

I'm trying get my application to run in fullscreen. That means no status pane, no title pane, but I DO want the menu buttons ("Options" + "Exit", the CBA) to be visible. Can somebeody please tell me how to do it?

Firstly, what I have done so far.
The GUI architecture uses derived CAknViewAppUi, CAknView and CCoeControl (each in an own class, as Carbide with GUI support would create it).
It all runs on Symbian 9.2 (N82) in landscape mode.

There seem to be many ways to achieve "fullscreennes".
I have experimented with (all done in ConstructL of CCoeControl derivation): SetExtentToWholeScreen(), SetRect(), SetExtent(), SetCanDrawOutsideRect().
A combination of these functions results in fullscreen.

I know that I can hide the status pane, title pane and cba, but there is no need to. I draw over them.

Still, I would like the CBA to be visible.
Since my main CCoeControl is periodically drawn (the camera's viewfinder), in Draw( const TRect& aRect ) const, I tried to Draw the Cba there:
AppUi()->Cba()->DrawDeffered (DrawNow crashes).
I hoped that the Cba() would be drawn after the CCoeControl has been drawn, but that didn't help.


An example of what I want to do would be the standard Camera application - it has fullscreen with "Options" and "Exit" visible. Do I have to draw them extra as Bitmaps or using some type of DrawText, or can I make the CBA be drawn over my CCoeControl (the viewfinder)?

Or can I change the drawing order (z-buffer like)? To make first my CCoeControl be drawn, then CBA. I would probbably have to hide status pane then.

I have even tried setting the Extent and/or Rect of my CCoeControl so that it excludes the CBA buttons (which are on the right side).
The CBA buttons are then visible, but the right half of the viewfinder was not visible, as expected.
My hope was that after setting SetCanDrawOutsideRect() I would be able to draw the right half, but that was not the case - it wasn't visible.

e.g.
000000000022
000000000011
000000000011
000000000011
000000000022

where 0 is the area set by SetRect / SetExtent, 1 is the area I thought would be renderable if I set SetCanDrawOutsideRect(), 2 is the area of the CBA buttons.
But as mentioned, area 1 was not rendered. Note that the upper-most and lower-most 0 line covers the title / status pane.

Thanks in advance

Try if AknLayoutUtils::LayoutMetricsRect with EControlPane can help you (basically you should "subtract" this rectangle from full screen)

[NevenS]

How can I subtract the rectangle from fullscreen?
Is there a "layout-mask" that I can update? How do I do that?

And shouldn't there be two rectangles, one for the "Options" and one for the "Exit" button?

You have to determine where the CBA is located, and indent that side of your view rectangle. Something like

// screen and cba are TRect-s
if(cba.Width()==screen.Width()) // cba is horizontal, screen sized
    if(cba.iTl.iY==0) // cba is on the top
        screen.iTl.iY=cba.iBr.iY; // screen's top is moved to cba-s bottom
    else // cba is on the bottom
        screen.iBr.iY=cba.iTl.iY; // screen's bottom is moved to cba's top
else // cba is vertical
    if(cba.iTl.iX==0) // cba is on the left
        screen.iTl.iX=cba.iBr.iX;
    else
        screen.iBr.iX=cba.iTl.iX;

it may work or may not work, I have not tried actually.

ah, but that would make my right half of the viewfinder not be displayed, even that part where there are no buttons.

If we look at the screen's layout, I want to achieve
000000000022
000000000000
000000000000
000000000000
000000000022

where 0 is the viewfinder and 2 is the CBA.
If I do it just by setting the rightmost x coord of screen (viewfinder) to the leftmost of x coord of CBA, I would get:

00000000022
000000000..
000000000..
000000000..
00000000022

where .. is not rendered (not updated by GUI).


My idea was that even if I set the viewfinder's ccoecontrol right-most x to left-most x of CBA, that I would be able to render outside of the rectangle
if I set SetCanDrawOutsideRect() and render the . part explictily. But it was culled anyway.



Can I at least change the drawing order? First render the viewfinder and then the CBA on top?
And if yes, how?


Another solution (more of a hack) would be to display the "Options" and "Exit" as text (DrawText).
And when I press "Options" the whole StatusPane and Menu moves into focus and is rendered on top of the viewfinder anyway (the way I want it).

Hi NevenS,

I faced the same problem a couple of months ago and spent a lot of time trying to solve it. Finally I 'invented' something which may not be very elegant, but does work.

CEikButtonGroupContainer* cba = CEikButtonGroupContainer::Current();
iPrevOrdinalPos = cba->DrawableWindow()->OrdinalPosition();
cba->DrawableWindow()->SetOrdinalPosition(0);

I restore CBA's ordinal position when the control gets destroyed, that's what iPrevOrdinalPos is for.

This trick works for me, I hope it helps.

Cheers,
Maciej
