Hide/ Un-Hide CBA Button

[somnathbanik]

Hi,
I am trying to hide and un-hide the cba button during run time.
The code below helps me to hide the cba button

  CEikButtonGroupContainer*  cba = CEikButtonGroupContainer::Current();
     cba->MakeVisible( EFalse );

But if I use

  CEikButtonGroupContainer*  cba = CEikButtonGroupContainer::Current();
    cba->MakeVisible( ETrue );

I am not able to unhide the cba button


Please suggest me.

may be you need to use :

cba->MakeVisible( ETrue );
cba->DrawDeferred or cba->DrawNow

I tried that and getting Kern_exec 3

  CEikButtonGroupContainer* myCba = CEikButtonGroupContainer::Current();

    CleanupStack::PushL( myCba );

    myCba->SetCommandSetL( R_CUSTOM_CBA1  );

    myCba->MakeVisible( ETrue );

    myCba->DrawDeferred();

    CleanupStack::Pop();  // myCba

One way is to get CBA buttons through the CAknAppUi::Cba() function and then call CEikButtonGroupContainer's MakeVisible() .

Another way is to create a full-screen application, like described here http://wiki.forum.nokia.com/index.ph...ymbian_C%2B%2B and here http://wiki.forum.nokia.com/index.ph...de_on_touch_UI And change from full-screen mode to a windowed one when you need it.

I am trying to hide the softkey while loading the app, and it worked perfect
I did this way
appui.cpp

ConstructL()
{
...
Cba()->MakeVisible(EFalse); 
...

When I try to display the softkey in run time , i called the function , but nothing happens. I can't see the softkey, no responce at all.
appui.cpp

ChangeOrientation()
	  {
	  Cba()->MakeVisible(ETrue);
}

could you please help me to enable the hidden softkey?

Please suggest me.

Well, if you still prefer a CBA-based solution, try the following:

#include <avkon.rsg> // include this to use R_AVKON_SOFTKEYS_EMPTY
#include <eikbtgpc.h>

...

// Disable CBA buttons
CEikButtonGroupContainer* cba = CEikButtonGroupContainer::Current(); // or CAknAppUi::Cba()

if ( cba != NULL )
{
cba->SetCommandSetL( R_AVKON_SOFTKEYS_EMPTY );
cba->DrawNow();
}

cba->DrawNow();
}

I can disable teh cba button but after disabling if I want to enable its not working, I need to enable the disabled cba button

I guess in this case the sequence of steps will be just the same, except that you'll be using your own softkey resource:

if ( enableButtons )
{
cba->SetCommandSetL( R_YOUR_APPLICATION_CBA_BUTTONS_SET );
cba->DrawNow();
}
else
{
cba->SetCommandSetL( R_AVKON_SOFTKEYS_EMPTY );
cba->DrawNow();
}

cba->DrawNow();
}

I tried this way
Appui.cpp

Constl()
{
...
  CEikButtonGroupContainer* cba =  CAknAppUi::Cba();
    if ( cba != NULL )
    {
    cba->SetCommandSetL( R_AVKON_SOFTKEYS_EMPTY );
    cba->MakeVisible( EFalse );
     cba->DrawNow();
    }
    
...

the above code helps me to display the app in full screen when it starts. Now at a sertain point of time when the app is running I want to display the menu bar. do I did in this way

void CMusicalAlarmAppUi::ShowMenuBar()
	{
	
CEikButtonGroupContainer* cba =  CAknAppUi::Cba();

	    if ( cba != NULL )
	    {
	    cba->SetCommandSetL( R_AVKON_SOFTKEYS_OPTIONS_EXIT );
	    cba->MakeVisible( ETrue );
	     cba->DrawNow();
	    }

	
	
				   	}

but not able to display the menu bar.
Any one please suggest me. I am trying this for a long time.

May be you might have to put the code for a particular view to hide/un-hide its cba keys, try like this:


CEikButtonGroupContainer* cba = CEikButtonGroupContainer::Current();
if (cba != NULL) {
cba->SetCommandSetL( R_AVKON_SOFTKEYS_OPTIONS_EXIT );
cba->MakeVisible( ETrue );
cba->DrawDeferred();
}

put the above code in some function in the view class in which you want to un-hide the cba keys.

I don't know why its not working for me. even I create a function in my view class and paste the code there. Any way i did rather differently
First i set SetExtentToWholeScreen(); to make the full screen and at a particular point I call this function below

void CMusicalAlarmContainer::SetWindow()
	{
	TRect aRect;
	SetRect(TRect(TPoint(0,0),TPoint(360,580)));
	   // SetRect(aRect);
	    ActivateL();
	}

This way i could make it done. I would like to know is this a write process , I am targeting 5th edition and S^3 device

use
/*
Make it visible at first as others suggested
*/
cba->drawableWindow()->setOrdinalPosition(0);
cba->drawnow();
