Hide/Show My App and Getting Key Like #123...

[ArvinShahidi]

Hi, I could hide my application by this codeSymbian C++ s6)


CEikonEnv::Static()->RootWin().EnableReceiptOfFocus(EFalse);
CEikonEnv::Static()->RootWin().SetOrdinalPosition(-1000, ECoeWinPriorityNeverAtFront);


Now, I do not know how can I show it again, because the Symbian focus is located on another app after Set Ordinal.
Could you please help me for finding a solution?
it is important to me that my app appears with a specific code like #123 ...
If you know better way I would appreciate help me.

Thanks

try searching for threads talking about CaptureKey, or check wiki for exmaples. Then when you capture the key, just use the SetOrdinalPosition to bring your app back to teh front(that also should have wiki exmaple, as well as loads of old discussion threads).

Thanks for your reply.

I have just found a class as you can check here:

" http://wiki.forum.nokia.com/index.ph...ui_application "

Then I have added this class to my app as CKeyCapture class and when I am writing this code :

CKeyCapture* MyKey = new CKeyCapture;

in MyAppUi::ConstructorL()

I have an error like "Error : CKeyCapture :no appropriate default constructor available "
Could you please help me for getting the point. ?

try it like:

CKeyCapture* MyKey = new(ELeave)CKeyCapture();

[A.A.M.]

Try to do like this:

in MyAppUi.h

class CCapKey2AppUi : public CAknAppUi, MKeyCallBack 
    {
    ...
    ...
    private:
       CKeyCapture* iMyKey;
    ...
    }

in MyAppUi.h cpp in MyAppUi::ConstructorL()

iMyKey = CKeyCapture::NewL( this );

Thanks for your reply.

it does not work, and shows me some errors like :

error C2065: 'iMyKey' : undeclared identifier
\SRC\MYappui.cpp(79) : error C2664: 'NewL' : cannot convert parameter 1 from 'class MYAppUi *const ' to 'class MKeyCallBack &'

Thanks,

[A.A.M.]

Are you sure that you have already declared iMyKey in the header file?

[skumar_rao]

also your appui is not derived from MKeyCallBack

[ArvinShahidi]

Yes, but I have this one as well:

"Error : Can not parameter 1 from class CCapKey2AppUI *const to class MKCallBack&"

Thanks,
Arvin

[skumar_rao]

consider reading #8

[ArvinShahidi]

I have just added

In MyAppUi.h

class CKeyCapture;

class CCapKey2AppUi : public CAknAppUi, MKeyCallBack
{
public:

void ConstructL();

protected:

private:

CKeyCapture* iMyKey;

};


in MyAppUi.cpp file

void CCapKey2AppUi::ConstructL()
{
iMyKey = CKeyCapturer::NewL(this);
}


but I have the error that I was saying to you.

Thanks
Arvin

[skumar_rao]

try like this iMyKey = CKeyCapture::NewL( *this );

[ArvinShahidi]

It does not work and it gives me :

error " C2440 :'=' cannot convert from class CKeyCapture* to CKeyCapture*"


sorry for bothering you.

thanks

[ArvinShahidi]

Is it possible that I send you my App by email ?

[A.A.M.]

Check class names that you are using:

I have just added

In MyAppUi.h

class CKeyCapture;

class CCapKey2AppUi : public CAknAppUi, MKeyCallBack
{
public:

void ConstructL();

protected:

private:

CKeyCapture* iMyKey;

};


in MyAppUi.cpp file

void CCapKey2AppUi::ConstructL()
{
iMyKey = CKeyCapturer::NewL(this);
}

If you use class from this article ( http://wiki.forum.nokia.com/index.ph...ui_application ) then add to your MyAppUi.h

#include "KeyCapturer.h"
...

class CCapKey2AppUi : public CAknAppUi, public MKeyCallBack
{
private:
       // from MKeyCallBack
       void KeysMap(const TDesC& keys);  
...
private:

	CKeyCapturer* iMyKey;
}

in MyAppUi.cpp file

void CCapKey2AppUi::ConstructL()
{
...
iMyKey = CKeyCapturer::NewL(*this);
}

void CCapKey2AppUi::KeysMap(const TDesC& keys)
{
// handle event
}
