How to add a button to View?

I want to add CommandButton to View and I use resource CMBUT:
- In .rss:
RESOURCE CMBUT r_ex_button
   {
   version=0;
   behavior=2;
   layout=1;
   extension=0;
   txt="";
   bmpfile="*";
   bmpid=EMbmExicon;
   bmpmask=EMbmExiconm;
   }
- In class appview:
   TResourceReader reader;
iCoeEnv->CreateResourceReaderLC(reader, R_EX_BUTTON);
CEikCommandButton* button = new CEikCommandButton();
button->ConstructFromResourceL(reader);
CleanupStack::PopAndDestroy();

Re: How to add a button to View?

It's very simple. Not need to RESOURCE.
For make Button on view you must:
1)Write in CExampleAppView class *.h-file

Code:

CEikCommandButton* iBtnTest;

2)...and include

Code:

#include "eikcmbut.h"

3)In *.cpp-file of CExampleAppView classÂ in ConstructL

Code:

iBtnTest = new (ELeave) CEikCommandButton();
CleanupStack::PushL(iBtnTest);
iBtnTest->SetTextL(_L("Test"));
iBtnTest->SetObserver(this);
iBtnTest->SetContainerWindowL(*this);
TSize size = iBtnTest->MinimumSize();
iBtnTest->SetExtent( TPoint(aRect.Width() - (size.iWidth + 5),
aRect.Height() - (size.iHeight + 36)),
size);
CleanupStack::Pop();

4)... in CountComponentControls

Code:

TInt counter = 0;
if (iBtnTest)Â Â counter++;
return counter;

count this control...
5)... in ComponentControl

Code:

switch (aIndex)
{
Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â ................
case 4:
return iBtnTest;
Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â ................
default:
return NULL;
}

6)... in HandleControlEventL insert functionality for your Button

Code:

if(iBtnTest == aControl)
{
Â Â Â Â Â Â Â Â Â ........................
}

7)... and finally in ~CExampleAppView correct delete control

Code:

if(iBtnTest)
delete iBtnTest;
